What evidence should a buyer approve before releasing an export mold with textured or glossy visible surfaces?
Link the part drawing and visible-surface map to the texture or polish target, resin and color basis, controlled inspection conditions, labeled trial samples, defect limits, retained samples and correction log. Keep the selected finish, measured gloss, sample approval, mold shipment, price and delivery as NEEDS_EVIDENCE until the exact project file supports them.
Decision checklist
- Mark cosmetic and non-cosmetic zones on the drawing before mold texturing.
- Define the texture code, polish class, gloss target or physical reference sample.
- Lock the resin and color basis used to judge appearance.
- Approve labeled samples and written defect limits under agreed inspection conditions.
Appearance approval starts with a surface map
A finish callout is not enough when only selected faces are visible to the end user. The approval file should mark A, B and C surfaces, hidden zones, parting lines, gate vestige areas and any faces that require texture, polish, EDM finish or no cosmetic requirement.
Protolabs describes multiple polishing, bead-blast and Mold-Tech routes and recommends identifying the exact surfaces and texture specification. That supports a documented review, but it does not prove the finish of a specific GEERPOWER mold.
Approve the surface map and reference standard before treating photos as appearance evidence.
Review material, samples and defect limits together
Part geometry, mold design, resin, pigment, drying, filling, packing and cooling can all change the visible result. Record the resin grade, color basis, cavity number, shot sequence and trial condition with every sample set.
Use controlled lighting, viewing distance and accept-reject examples for sink, weld lines, flow marks, scratches, drag marks and gate vestige. Retain the signed reference samples so later corrections and repeat trials are compared against the same decision basis.
- Visible-surface drawing with finish requirement by zone.
- Texture plaque, gloss target, color chip or approved master sample.
- Trial samples labeled by cavity, material and date.
- Defect photographs with location and acceptance limit.
- Retained samples, correction log and surface-care handover note.
Keep project claims evidence-gated
A polished insert or textured cavity photo does not prove final molded-part appearance. Avient notes that mold surface treatments, material choice and mold design influence gloss and surface behavior, while Protolabs explains that texturing can affect draft and material response.
GEERPOWER should not claim a final texture match, gloss value, color consistency, production yield, mold life, price or delivery until the exact project records are reviewed. Any open item belongs in the correction and shipment decision log.
Common buyer questions
Is a texture code enough for export mold approval?
No. The buyer also needs the visible-surface map, material and color basis, inspection method, labeled samples, defect limits and retained reference samples.
Should gloss be approved from supplier phone photos?
No. Photos can support discussion, but approval should use controlled lighting, agreed viewing conditions, labeled samples and written accept-reject limits.
Can texture be changed after mold completion?
Sometimes, but the route may require polishing, re-texturing, insert replacement or geometry changes. The mold maker should document feasibility, risk and retest evidence.
