02 · Foreword
Why This Manual Exists
Application success depends on five things working together.
应用是否成功 · 取决于五项变量同时配合
A rhinestone material is not a finished product. It becomes a finished product on a buyer’s line — under a specific heat-press, on a specific fabric, with a specific glue, by a specific operator. Five variables decide whether the result holds.
Heat-press temperature must activate the adhesive without scorching the receiving fabric. A 10°C swing can be the difference between a permanent bond and a sample-day disaster.
热压温度要既激活胶膜 · 又不烧到面料。10°C 的偏差 · 就是永久粘合和打样翻车的距离。
03 · Pressure
压力
Press pressure transfers the stone field onto the substrate. Too little and stones float; too much and stones embed or fabric puckers.
压力把钻面转移到承接面。压力不够 · 钻浮起 · 压力过大 · 钻陷入或面料起皱。
04 · Adhesive
胶膜
Hot-melt activates under heat. 513 double-sided is pressure-sensitive. Sew-on uses no adhesive. The choice depends on the receiving material and on whether the application will see heat in production.
Where in the line the rhinestone gets applied. Before cutting, after cutting, after sewing, on a finished piece — each position has its own failure modes.
水钻在产线上哪个阶段上贴。裁前、裁后、缝后、成品上 · 每个位置都有自己的失败模式。
The non-negotiable rule
Always sample on the buyer’s actual material before bulk.
No catalog spec, no application parameter, no factory recommendation replaces a sample test on the buyer’s actual production fabric, with the buyer’s actual heat-press, under the buyer’s actual line conditions. This manual gives starting guidance. The buyer’s sample test gives the final answer.
This manual is built from seventeen years of running rhinestone accessory production inside the same Pujiang factory. The parameters are starting guidance, not absolute guarantees. The rules apply to every product line LOCA makes.
All eight start from a stone, a base, and a way to bond them.
八条产品线 · 起点都是钻、基底、与把两者结合的工艺
LOCA produces eight product lines, grouped by base structure. Crystal Mesh is the upstream material — most other lines either share its flexible adhesive base or extend it with a fabric back and an inner core.
For a glossary mapping buyer-side search terms (rhinestone trim, rhinestone sheet, rhinestone applique) to the LOCA product codes above, see the Buyer Vocabulary Guide.
The LOCA 12-element material library · 乐卡 12 元素材料库
All seven non-PVC product lines above draw from the same 12-element material library — four families organised by element type. The exact mix in any finished product is selected from this library per order.
* Hot-fix rhinestone (烫钻 · also written as 平底烫钻 to emphasize structure) is a stone material with hot-melt adhesive already bonded to the back as part of the product spec — ship-ready · no separate backing step required. See Page 09 · BDS for the full element library breakdown.
A starting reference. Each cell marked “•” means the product line has been actively used in that finished-product category. Empty cells aren’t exclusions — they mean the combination is uncommon or untested at scale.
If the application you’re planning isn’t in the matrix above, it doesn’t mean it can’t be done. Many custom projects sit between the standard categories; LOCA’s development team handles custom-fit work routinely.
Read across by application, then down by stone quantity.
If you’re building a footwear collection: the Footwear column gives you five product lines that work (CM, DR, DL, DF, SP, SU, PVC). The next decision is volume: SU is fully-formed (highest unit cost, lowest factory labor on your end), SP is per-piece patches, CM/DR/DL are continuous materials that you cut and apply yourself.
举例 · 做一个鞋类系列：Footwear 这一列给你五条可行产品线（CM / DR / DL / DF / SP / SU / PVC）。下一步看单件钻量 · SU 是整体成型（单价最高 · 你工厂自己加工最少）· SP 是单片贴 · CM / DR / DL 是连续材料 · 你自己裁切贴。
05 · Material Compatibility
What Bonds, What Doesn’t
Material compatibility is starting guidance, not a guarantee.
材料兼容是起点指引 · 不是保证
The table below maps common substrates against LOCA’s primary application methods. “OK” means the combination is well-tested. “Test required” means LOCA has done it but the buyer’s specific material grade matters more than the category. “Avoid” means the combination has a known failure mode.
Standard heat-press settings work. Heavy cotton may need higher press time.
Polyester (woven)
OK

Three notes that apply across every row above:
三条贯穿全表的提醒：
Material grade matters more than material category. A “PU” can be a thin coating on cotton, a thick foam-backed sheet, or a synthetic leather. Each behaves differently under heat.
Coloured / printed substrates need lower hot-press temperatures. Pigment surfaces are heat-sensitive in ways the base material isn’t.
The buyer’s heat-press machine matters. Two presses at the same setpoint can deliver different actual surface temperatures. Calibrate before bulk.
When the receiving material is unknown, heat-sensitive, or expensive to ruin (silk, leather, vintage pieces, dyed surfaces), the safe default is 513 double-sided adhesive. It activates under pressure, leaves no heat damage, and can be repositioned on the substrate up to the final press. Hot-fix is faster and more permanent — but only after confirmation that the substrate tolerates the temperature.
The upstream material in the LOCA system. Stones set on a flexible adhesive base, supplied as sheet or roll, sized to either a re-processing factory or an end-product factory depending on what the buyer does with it next.

Application notes · 应用提示
Storage matters more than buyers expect. Crystal Mesh has two storage failure modes that show up after shipment if conditions are wrong:
储存条件 · 客户最容易忽视的环节。水钻胶网片有两种储存失败模式 · 在收货后才显现：
Humid environment — prolonged exposure causes the silver backing layer on each stone to detach. Stones then fall out of the glue field even before application.
Heat exposure — high storage temperature softens the adhesive film. Stones drop from the field at the next handling.
潮湿环境长期存放 — 水钻背面的银层会脱落 · 还没开始应用 · 钻就先掉出来。
高温环境 — 胶膜软化 · 下一次搬动钻就脱落。
LOCA storage recommendation
Store sealed, cool, dry, ventilated.
Keep Crystal Mesh in its sealed packaging until use. Storage location should be cool, dry, and ventilated — not a closed cabinet near a heat source, not a humid basement, not a tropical warehouse without climate control. If the buyer’s warehouse has variable humidity or temperature, request shorter delivery batches and use within 60 days.
Stones falling out of the glue field before application.
应用前 · 钻就从胶面掉出来
Cause: prolonged humid storage detached the silver backing layer; or heat softened the adhesive.
原因：潮湿存放过久 · 银层脱落；或储存温度过高 · 胶软化。
Fix: retire the affected batch; verify storage conditions before continuing; request fresh material in sealed packaging.
处理：受影响批次报废；核查储存环境再继续；请乐卡补发密封包装新料。
Stones embed too deep into the substrate after press.
压贴后 · 钻陷入承接面过深
Cause: pressure too high for the substrate, especially common on soft cotton, thin polyester, or fine knit.
原因：承接面承受不了该压力 · 软棉、薄涤、细针织最常见。
Fix: drop pressure one notch (heavy → medium, medium → light) and re-sample on the same fabric.
处理：压力下调一档（重 → 中 / 中 → 轻）· 同面料重打样。
Adhesive does not bond — trim peels after first wash.
胶没粘住 · 首次洗后条带脱落
Cause: temperature below 180 °C activation point; or press time below 15 seconds; or the substrate has a release-treated surface (silicone-coated polyester, water-repellent fabric).
原因：温度未到 180 °C 激活点；或热压时间不足 15 秒；或承接面有离型处理（涂硅涤纶、防水面料）。
Fix: verify press calibration; if substrate is suspected, switch to 513 double-sided adhesive (see Material Compatibility).
Fabric-backed continuous rhinestone trim with a selectable inner core. The inner core decides everything downstream — drape, cutting, sewing, durability under wear. Pick the core first; the row count and width follow from the application.

All standard inner cores tolerate up to 350 °C for short exposures, which is well above any hot-press temperature the trim will see in production (180 °C is standard). This makes Diamond Rope unusually forgiving in downstream processes — including secondary heat treatment, embossing, or hot-knife cutting at the buyer’s end.

Application methods · 应用方式
Diamond Rope is the most-flexible product in the LOCA system in terms of attachment method. The same piece can be:
水钻抽条在乐卡体系里 · 是应用方式最灵活的产品。同一段水钻抽条可以：
Glued — surface-bonded with appropriate adhesive for the substrate
Hand-sewn — stitched through the fabric back, standard upholstery or beading needle
Machine-sewn — industrial sewing through the back, away from the stone field
Combined — sewn at the ends, glued in the middle, or vice versa
粘贴 — 根据承接面选合适胶水
手工缝制 — 缝穿布底 · 用标准家纺针或串珠针
机器缝制 — 工业缝纫机走布底 · 避开钻面
组合方式 — 两端缝、中间粘 · 或者反过来
Common problems · 常见问题
Adhesive peels from trim after a few weeks.
胶在几周后从条带上脱落
Cause: the buyer pulled hard on the adhesive layer during application, separating the bond. Diamond Rope’s glue is not designed for high-force peel resistance.
原因：应用时用力拉扯胶层 · 把粘合层撕开了。水钻抽条的胶不是为抗剥离强力设计。
Fix: instruct line operators to press, not pull. If trim must be repositioned, lift gently with the trim direction, not against it. For high-stress placements (children’s wear, athletic), use sewn application.
Cause: long-term humid storage. The same silver-layer detachment problem that affects Crystal Mesh also affects Diamond Rope.
原因：潮湿环境长期存放。和水钻胶网片一样的银层脱落问题。
Fix: seal in original packaging, store cool / dry / ventilated, use within 60 days of receipt for best results.
处理：保持原包装密封 · 阴凉干燥通风 · 收货后 60 天内用完最佳。
08 · Product Application
DL · Diamond Lace
Diamond Lace.
水钻胶条
Backless flexible adhesive trim. Same hot-press protocol as Crystal Mesh — same temperature, same time, same press calibration. The buyer-facing difference is form factor: Diamond Lace ships in narrow row counts (2 / 3 / 4 / 5 rows), pre-shaped to be cut to length with scissors and applied directly.
Crystal Mesh and Diamond Lace share the same flexible adhesive base. The split is about shape pre-commitment:
水钻胶网片和水钻胶条共用同一种柔性胶底。区别在于成型程度的预设：
Crystal Mesh ships as a stone-filled field. The buyer cuts the motif shape out of the field. Cutting waste is part of the price.
Diamond Lace ships as a pre-formed trim already shaped to row count and width. The buyer cuts only the length. Zero motif-shape waste.
水钻胶网片 出整片钻面 · 客户从片上裁出图案形状 · 裁切损耗算在价格里。
水钻胶条 出已成型的条带 · 已经按排数和宽度预成型 · 客户只裁长度。零图案损耗。
If the buyer needs a custom shape, use Crystal Mesh. If the buyer needs a continuous narrow trim, use Diamond Lace.
需要自定义形状 · 用水钻胶网片。需要连续窄条 · 用水钻胶条。
Row count selection · 排数选择
All four row counts (2 / 3 / 4 / 5) use the same flexible adhesive base. Choose by the visible width you need on the finished product. Scissors cut to length — no special tooling required.

Combinations to avoid · 不推荐的组合
Not recommended
Rhinestone + steel bead on Diamond Lace.
The Diamond Lace flexible adhesive base is not engineered to support steel beads alongside rhinestones in the same trim. For multi-element layouts that combine rhinestones with electroplated steel beads, use Bangle Diamond Sticker instead — it’s the dedicated multi-element strip product.
Diamond Lace is the most-forgiving product in the LOCA system. The flexible adhesive base, simple cutting protocol, and shared parameters with Crystal Mesh mean failures are rare when the buyer picks the right width and row count for the application.
Trim looks too wide / too narrow on the finished piece.
成品上 · 条带显得太宽或太窄
Cause: wrong row count for the application. A 5-row Diamond Lace looks heavy on a delicate neckline; a 2-row looks lost on a wide belt.
原因：排数和应用不匹配。5 排水钻胶条贴在精致领口显重 · 2 排贴在宽腰带又显薄。
Fix: request a sample swatch in 2-3 adjacent row counts before bulk. Place each against the actual product and check visible width at intended viewing distance.
The multi-element product in the LOCA system. Most BDS strips ship with a built-in self-adhesive backing — no heat press required — and combine rhinestones with a wide range of decorative elements selected per order. One strip equals one finished bangle.

Element library · 元素库（LOCA 12 元素标准）
BDS production combines elements from LOCA’s 12-element standard library — the same library shared across all seven non-PVC product lines. What makes BDS the “multi-element” product is the breadth of combinations LOCA runs in a single bangle strip. Four families, twelve elements:
C · PearlC · 珍珠
Faux pearl — glass or resin core · soft non-reflective accent.
C · Glass beadC · 玻璃珠
Round glass bead · refractive but non-faceted.
C · Electroplated steel beadC · 电镀钢珠
Hard metal accent · finish families: rose gold / black + gun / gold / silver.
D · Shaped claw settingD · 异形爪
Metal claw setting in non-standard shapes · mechanical setting (no glue).
D · Claw chainD · 爪链
Continuous claw-set chain · holds stones under stress · alternative to adhesive-bonded trim.
Any element from this library can be combined with rhinestones in the same strip. Multi-element layouts are LOCA’s signature in the bangle category. For the buyer-side terminology mapping of this library, see the Buyer Vocabulary Guide.
The self-adhesive backing is pressure-sensitive. Application onto the buyer’s bangle base:

The strip applies to most common bangle bases: metal frames, acrylic / plastic bangles, leather wrist straps, fabric-covered bangle bases. For a buyer-side guide to width tier selection, stone density, and bangle market context, see the Bangle Decoration Guide.
Silver-plated elements need promptness or resin coating.
Silver-plated steel beads and any silver-finish elements oxidize over time through air contact — especially in humid conditions. Two ways to handle this in production: (1) use silver-bead orders promptly after receipt and keep sealed packaging until use, or (2) request resin-coated silver elements at order time — the resin layer prevents air contact and significantly slows oxidation.
Silver elements turning dull or tarnishing during storage.
银面元素在储存中失光或发黑
Cause: oxidation. Silver-plated elements react with air, accelerated by humidity and time.
原因：氧化。镀银元素和空气反应 · 湿度和时间加速。
Fix: use within 30–60 days of receipt; seal in original packaging when not in use; for long storage planning, request resin-coated silver elements at order time.
Pre-shaped 3D rhinestone applique. Where Crystal Mesh, Diamond Lace, and the other trim products ship as continuous length, Diamond Flower ships as a finished single-piece motif. Laser cut, then pressed into dimensional form, then hand-set with crystals. One piece per placement. Nothing to cut to length, nothing to choose by row.

Why Diamond Flower exists alongside trim products · 钻花 vs 抽条 / 网片
Trim products (Crystal Mesh, Diamond Lace, Diamond Rope) ship as continuous length and the buyer commits to motif shape at cutting time. Diamond Flower commits to motif shape at LOCA’s production time — the laser-cut, 3D-formed silhouette is fixed before shipment.
Trim products: maximum flexibility (any shape from one roll), but the buyer carries the cutting waste and shape-decision burden.
Diamond Flower: zero cutting waste, zero shape-decision burden, three-dimensional visual lift that flat trim cannot match. Trade-off is per-piece cost vs per-metre cost.
抽条类：灵活性最大（一卷可裁任意形状）· 但裁切损耗 + 形状决策都由客户承担。
钻花：零裁切损耗 · 零形状决策负担 · 立体感是平面抽条永远做不到的。代价：按件计价 vs 按米计价。
For multi-piece couture or bridal layouts that need a specific recurring motif (butterfly, rose, star), Diamond Flower is the right choice. For continuous edge treatment, use a trim product.

Combinations to avoid · 不推荐的组合
Not recommended
Cutting or trimming the Diamond Flower outline.
The 3D heat-pressed structure depends on the exact die-cut silhouette. Trimming the edge after shipment compromises the dimensional form and exposes the unfinished base. If the buyer needs a different motif size or shape, request a new mold — do not modify the shipped piece.
3D 热压结构依赖精确的激光切割轮廓。出货后再裁边会破坏立体造型 · 同时暴露未处理的基底。需要不同尺寸或形状的 motif · 请乐卡重新开模 — 不要修改已出货的件。
Common problems · 常见问题
3D shape flattens or distorts after storage.
储存一段时间后 · 3D 立体感变扁或变形
Cause: stacking pressure (pieces piled flat under weight) or heat exposure (storage above 35°C softens the dimensional form).
原因：堆压（多片平放叠加受重）或高温（储存温度超过 35°C 让立体结构软化）。
Fix: store flat in single-layer trays with a divider sheet between layers; keep below 30°C; use within 6 months of receipt.
处理：单层托盘平放储存 · 层间加隔板；温度保持 30°C 以下；收货后 6 个月内用完。
A few hand-set crystals fall off during shipment.
运输过程中 · 个别手工嵌的水钻脱落
Cause: Diamond Flower includes hand-set crystals as part of step 3 of the 4-step process. Hand-set bonding is strong but not laser-grade. Multi-piece cartons under shipping vibration may dislodge a small percentage.
Fix: LOCA includes 2–3% extra crystals (matching size + colour) in every bulk shipment of 500+ pieces. Use these to spot-repair on receipt before bulk application.

Die-cut motif patches that share Crystal Mesh’s flexible adhesive base. Same hot-press parameters, same application protocol — the only difference is shape pre-commitment. A Shoe Patch ships already cut to a specific motif outline, ready to press-apply onto the substrate.

Common problems · 常见问题
Few unique to Shoe Patch. The product inherits Crystal Mesh’s flexible adhesive base, so any application failures are typically substrate-side — e.g., heat-sensitive coloured PU, glossy polyester requiring reduced temperature, water-repellent coatings preventing bond. See Page 05 · Material Compatibility for substrate-specific guidance.
For a deeper buyer-side guide on choosing between Shoe Patch, Crystal Mesh roll, or finished Shoe Upper for footwear projects, see Rhinestone Inputs for Shoe Factories.
Finished shoe-upper component. SU sits downstream of every other LOCA product: rhinestone trim, motifs, and structural fabric all integrated into a complete vamp form before shipment. The shoe factory receives a piece that is ready to attach to a sole, and removes one entire production stage from its own line.
Why Shoe Upper exists alongside trim products · 鞋面 vs 抽条 / 鞋花
A shoe factory has three ways to source rhinestone decoration. Buy raw stones and apply in-house. Buy LOCA trim products (Crystal Mesh, Diamond Rope, Shoe Patch) and integrate at its own factory. Or buy LOCA Shoe Upper, and remove the decoration step entirely.
Raw stones: lowest material cost, highest labour cost, requires skilled application team.
Trim products: balanced cost, the buyer keeps the design decision but skips raw stone setting. Most shoe factories sit here.
Shoe Upper: highest per-piece cost, lowest labour cost on the buyer side. The shoe factory becomes a sole-and-assembly operation. Good for factories scaling fast or running rhinestone designs irregularly.

Combinations to avoid · 不推荐的组合
Not recommended
Sole assembly without sample-fit verification.
Each SU shape is engineered to a specific shoe-last profile. Mounting onto a sole with a different last curvature can cause the vamp to wrinkle, gap at the toe, or pull at the heel. Always verify a sample SU against the production last before bulk assembly — LOCA sends one fit-test pair before every bulk order.
Cause: SU is hand-finished in step 3. Left-right pairs are matched during QC, but a small percentage of late-stage hand-finishing variation can occur in dense-pave designs.
Fix: on receipt, lay all pairs flat in a single layer and visually scan for mismatch. LOCA replaces any rejected pairs at no charge if reported within 14 days of receipt.
处理：收货后单层平铺所有配对 · 目视检查不对称。14 天内反馈 · 乐卡免费替换不合格配对。
Vamp fabric pulls at the sole-bonding line during assembly.
装配时 · 鞋面布料在鞋底粘合线处被拉扯
Cause: sole-bonding adhesive too aggressive, OR sole assembly pressure too high, OR last curvature mismatch (see Combinations to avoid above).
原因：鞋底粘合胶太强 · 或装配压力太大 · 或鞋楦曲度不匹配（见上文"不推荐组合"）。
Fix: reduce sole-bond adhesive layer by 20%; lower press pressure one notch; if mismatch persists, request SU last-profile matched to your specific sole at next order.
处理：鞋底粘合胶层减薄 20%；装配压力调低一档；如仍不匹配 · 下次下单时请乐卡按你的鞋楦轮廓定制 SU 形状。

PVC · PVC Strip
PVC Strip.
PVC 亮条
Extruded PVC base with rhinestones embedded directly into the strip. PVC Strip is structurally distinct from every other LOCA product — it’s not a flexible adhesive sheet, not a fabric-backed trim, but an extruded continuous profile. As a result, its application method is also unique: natural latex bonding, not hot-press, not 513 double-sided.
Diamond Rope (fabric back + inner core) — used where the strip needs to drape, conform to curves, or be sewn into fabric assemblies. Soft and flexible.
PVC Strip (extruded continuous profile) — used where the strip needs to hold shape, resist moisture, or apply to plastic / sandal / slipper bases where the substrate itself is rigid. Firm and shape-holding.
A sandal strap, for example, often needs a rigid decorative trim that doesn’t deform — PVC Strip’s extruded profile delivers that. A bracelet sash needs softness and drape — Diamond Rope delivers that.
PVC Strip uses natural latex adhesive (天然乳胶) instead of hot-press or 513 double-sided:
PVC 亮条用天然乳胶 · 不是热压 · 不是 513 双面胶：
Apply natural latex to the substrate (or to the back of the PVC strip)
Position the strip along the application line
Press evenly along the length
Allow curing time per the latex specification (typically minutes, not seconds)
把天然乳胶涂在承接面上（或涂在 PVC 亮条背面）
沿应用线定位条带

Natural latex bonds well to PVC, plastic, and most rigid substrates common in footwear. Avoid heat exposure during the curing window — once the latex has cured, the bond is stable.
LOCA’s PVC Strip uses a special additive-free formulation.
This is relevant for buyers in markets with phthalate or plasticizer regulations — EU REACH, US footwear safety standards, certain Middle East import requirements. Specify your market’s formulation requirements at order time so LOCA can confirm compliance before bulk runs.

Common problems · 常见问题
PVC Strip is operationally simple once the latex application is dialled in. Most issues come from substrate prep or latex application volume:
PVC 亮条乳胶用量调好之后 · 操作很简单。常见问题来自承接面准备或乳胶用量：
Strip lifts at the edge after curing.
固化后 · 条带边缘翘起
Cause: insufficient latex coverage at edges; or substrate not properly cleaned (oils, dust, release agents preventing bond).
原因：边缘乳胶涂布不足；或承接面未清洁干净（油渍、灰尘、脱模剂阻碍粘合）。
Fix: ensure latex covers the full strip back — especially the edges; degrease substrate with isopropyl alcohol before application.
处理：确保乳胶覆盖整个条带背面 · 尤其边缘；用异丙醇清洁承接面再涂胶。
Visible glue line at the strip edge on finished product.
成品上 · 条带边缘有可见胶线
Cause: latex application too generous — excess squeezed out during press.
原因：乳胶用量过多 · 压贴时被挤出。
Fix: reduce latex per-meter usage; apply in a thinner consistent layer; press more slowly to allow displacement before squeeze.
处理：减少每米乳胶用量；涂得更薄更均匀；慢慢压贴 · 给胶位移留时间。

出问题时 · 先查这一页
Cross-product symptom-to-cause-to-fix table. Most issues that show up after a rhinestone trim or motif application trace back to seven recurring causes: temperature, pressure, dwell time, surface prep, storage, fabric chemistry, or pair fitment. This page collapses diagnosis from a multi-day email round-trip to a one-page lookup.

Symptom → Cause → Fix · 症状 → 原因 → 处理
Rhinestones fall off after application.
应用后 · 水钻脱落
Likely cause: hot-fix temperature too low (under 170°C), OR press time too short (under 12 sec), OR surface contamination (oil, dust, sizing chemical on fabric).
Fix: verify press calibration with thermometer (target 180°C); extend dwell time to 15 sec; pre-clean fabric surface with isopropanol wipe before application.
Likely cause: UV exposure during storage (sunlight on shelf), OR storage temperature above 30°C, OR shelf life exceeded (use within 6 months of receipt).
Fix: store in opaque packaging away from windows; keep storage area under 30°C; rotate stock first-in-first-out.
处理：用不透光包装储存 · 远离窗户；储存温度 30°C 以下；先到先用 FIFO 轮转。
Diamond Rope strap separates from fabric backing.
水钻抽条与布底分离
Likely cause: inner-core selection mismatch for the application (cotton in a wet-environment use, EVA at extreme temperature, PU in heavy-flex motion).
可能原因：内层选型与应用不匹配（潮湿环境用棉芯、极温下用 EVA、高频弯曲用 PU）。
Fix: consult the DR application page for inner-core selection by environment (PART 07); re-order with corrected inner-core specification.
处理：参考 DR 应用页按环境选内层（PART 07）· 用正确的内层规格重新下单。
BDS strip wrinkles or peels at bangle curve.
BDS 在手镯弯曲处起皱或脱粘
Likely cause: BDS width too wide for the bangle curvature (3mm and 6mm widths conform better than 12mm+); OR adhesive backing not fully activated by pressure during application.
Fix: for tight-curve bangles (under 6cm diameter), use 3–6mm widths; press firmly along entire strip length for 30 seconds; check page 09 for full BDS application guidance.
Likely cause: carton stacking during transit (too many pieces in one box, pressure on lower layers).
可能原因：运输中整箱堆压（一箱装太多 · 下层受压）。
Fix: request smaller-batch packaging (max 50 pieces per box for 7×7cm motifs and larger); place "do not stack" labels on cartons; see PART 10 for DF storage and care.
处理：申请小批量包装（7×7cm 以上的 motif · 每箱不超过 50 件）；箱外贴"勿堆压"标签；详见 PART 10 钻花储存与维护。
Fix: declare target market at order time (EU REACH / US CPSIA / India BIS); LOCA adjusts formulation to comply; for sun-exposed end use, request UV-stabilized PVC formulation.
Shoe Upper left-right pair mismatch detected after receipt.
收货后 · 发现鞋面左右配对不对
Likely cause: hand-finish stage 3 variation in dense-pave designs (see PART 12 SU common problems).
可能原因：密集嵌钻款式 · 第 3 步手工修整阶段的小比例左右差异（详见 PART 12 SU 常见问题）。
Fix: report mismatched pairs to LOCA within 14 days of receipt; LOCA replaces no-charge. Always inspect by single-layer flat lay before bulk sole-assembly.
处理：14 天内反馈不对称配对 · 乐卡免费替换。装鞋底前 · 单层平铺目视检查所有配对。
When in doubt
Send a photo + product code to LOCA before scaling production.
A clear photo of the symptom + product SKU / order reference + brief description of the application environment lets LOCA’s technical team diagnose within one working day. Pre-bulk diagnosis saves orders of magnitude more than post-bulk remediation.
Most rhinestone trim and motif applications hold for years under reasonable care. This page collects what LOCA asks its B2B buyers to pass down to their end consumers: a short list of do’s and don’ts that prevent the avoidable failures (chemical exposure, machine wash, harsh storage) from coming back six months later as warranty claims.
