This custom injection molded Top Segment is engineered with specialized light-blocking UV-stabilized ABS (white 9010 grade), ideal for light-shielding assemblies exposed to outdoor or UV-rich environments. We manufacture both the injection mold and finished plastic components with strict dimensional control, stable mass-production performance and qualified cosmetic finish. Built by our experienced mold engineering team, this single-cavity tool adopts submarine gate design for clean auto-degating, reducing post-processing work and guaranteeing consistent part appearance.

✅ Excellent Light Blocking Performance: Custom filled ABS formulation blocks light transmission reliably for optical shielding applications✅ UV Stabilized Formula: Anti-UV additive prevents yellowing, degradation under long-term ultraviolet exposure✅ High Precision Mold Fabrication: Mold core & cavity adopt 738H pre-hardened mold steel (HRC35-40), stable for long-run mass production✅ Clean Submarine Gate (Large Sprue): Automatic gate break, minimal witness mark on finished part✅ Controlled Shrinkage: Precisely set at 0.5% (1.005 mold factor) to hold tight tolerance✅ Custom Surface Texture: Front cavity finished to VDI18 texture; rear cavity fine polished for smooth release✅ OEM & ODM Available: We support DFM review, mold flow simulation, prototype sampling and mass molding service

Free DFM & mold flow analysis before mold machining T1 trial samples for dimension & appearance confirmation Mold repair, modification and lifetime maintenance support Flexible shipping options: Express / Air / Sea; FOB / DAP / DDU terms available Strict inspection report, dimension data and photos provided before shipment

Q1: Can you produce only the mold, or mass plastic parts as well?A: We support both. You can purchase only the injection mold, or order continuous molding mass production from our workshop.

Q2: What’s the lead time for this Top Segment mold?A: Standard lead time depends on drawing confirmation & sample approval; we will share formal schedule after DFM review.

Q3: Is the 738H mold steel suitable for long-term mass production?A: Yes. 738H (1.2738) pre-hardened steel at HRC35-40 delivers stable texture & dimension for medium to high volume ABS molding.

Q4: Can we adjust the light blocking effect or color shade?A: Yes. We can tune the filler ratio and masterbatch to meet your light opacity and white-color requirements.

Q5: What surface options can you offer besides VDI18?A: We provide various VDI textures, MT matte finish, high gloss polish, laser engraving and custom etching per your request.
