Automotive Lighting Mold
ZHIAN Lighting MoldOptical Precision
From DFM review and moldflow analysis to precision tooling, trial validation and 2K/3K injection support, ZHIAN builds a closed-loop delivery system for automotive lighting plastic molds.
Early Engineering Review
Optical surfaces, appearance zones, assembly datums, shrinkage, weld lines, venting, cooling and maintenance are reviewed at the data stage.
Precision Mold Manufacturing
Five-axis machining, high-speed CNC, wire cutting, EDM, deep-hole drilling, mirror polishing and insert management are organized for lighting molds.
2K/3K Injection Support
Injection molding and trial validation are supported with Yizumi and other leading machines for transparent PC, PMMA and multi-component appearance parts.
Inspection and Production Loop
Trial data, dimensional inspection, appearance review and assembly feedback are connected to help projects reach a stable production window.

The product center now covers headlamps, tail lamps, light guides, lenses, housings, reflectors and vanity mirror lighting components.
2K/3K Injection Becomes Critical for Automotive Lighting Appearance Parts
Through-type tail lamps, red-clear lenses and smoked optics require stronger control over mold positioning, color change and material bonding.
Light Guide Tooling Requires More Micro-Structure and Venting Control
Light guide molds must balance transparent material molding, micro-structure protection, uniform brightness and clean appearance.
