OPTICAL PC LIGHT COVER TOOLING

Transparent PC Light Cover Injection Mold

Production tooling for transparent PC light covers, lens covers, lamp shields, indicator windows, and optical diffuser panels. Engineered for light transmission control, surface clarity, birefringence management, and PC / PMMA / PC+ABS material systems used in automotive lighting and optical display assemblies.

High Light Transmission Low Birefringence Optical Grade Polish
1200 max tonnage
1M shots life
50 day lead time
Program Overview

Transparent PC light cover molds are built for manufacturing optical components that must satisfy light transmission, surface clarity, dimensional stability, and birefringence requirements. Tooling is developed from customer CAD data with wall thickness verification, gating strategy, warp prediction, and optical surface validation before steel procurement. Molds accommodate PC, PMMA, and PC+ABS grades with dedicated polishing of light-transmitting surfaces to SPI A1 or SPI A2 finish. Deliverables include DFM reports, mold flow analysis, steel certificates, T1 sampling, dimensional inspection reports, light transmission measurement data, and PPAP documentation packages suitable for automotive lighting and optical display supply chains.

Procurement FAQ
Q What data is required to quote a transparent PC light cover mold?
3D part data (STEP / IGES / native CAD), 2D drawing with tolerance and datum scheme, material specification including optical grade and light transmission target, annual volume forecast, surface finish requirement, machine tonnage available, and target cycle time if defined.
Q What is the typical lead time for light cover tooling?
Standard lead time is 40–50 days for single-cavity light covers and 55–75 days for multi-cavity tools or covers with optical inserts, complex slide systems, and overmold requirements. Lead time begins after design freeze and includes T1 sampling.
Q How is optical clarity controlled during tooling?
Light-transmitting surfaces are machined and polished to SPI A1 or SPI A2 finish with surface roughness verified by profilometer. Optical inserts use Stavax ESR or equivalent steel with dedicated polishing sequences and protective handling throughout assembly, trial, and storage.
Q How is birefringence managed in PC light covers?
Birefringence is managed through balanced cooling design, controlled packing pressure profiles, and gate placement validated in mold flow simulation. Slow fill rates and uniform mold temperature reduce molecular orientation, and polariscope inspection can be performed on T1 samples when specified.
Q What after-sales support is provided?
Support includes remote process troubleshooting, spare parts supply, wear insert replacement, hot runner service, optical surface restoration, and on-site technical assistance for production ramp-up when required.
