GP Mold leverages high-precision machining centers and multi-dimensional inspection systems (CMM, 3D scanning, visual inspection, T1 mold trial data acquisition) to achieve consistent control of mold cavities, cores, micro-prism textures, Fresnel structures, labyrinth sealing grooves, venting grooves, and parting lines. We have extensive experience in processing high-gloss automotive headlight lenses, complex prism decorative covers, weather-resistant outdoor lamp housings, and multi-material light guide cover molds. This ensures stable mold tolerances, uniform wall thickness, and balanced melt filling, preventing air entrapment, flow marks, silver streaks, burning, short shots, sink marks, warping, and birefringence shifts, thereby significantly improving validation speed and mass production yield.
GP Mold employs an "engineering one-project-one-solution" mold development strategy, providing precisely customized mold solutions based on customer product design, optical regulations, heat resistance conditions, usage scenarios, and production capacity requirements. Our engineering team is involved from the initial design stage, providing DFM optimization suggestions, focusing on optimizing the gating system and cooling circuit through ray tracing simulation, uniform mold temperature control (±0.3℃ accuracy), and stress birefringence prediction. We independently customize the mold structure, mold temperature control circuit, cooling plan, ejection design, and surface treatment solutions, ensuring stable scalability of the mold during both trial production and mass production.
The GP Mold mold material system and heat treatment solutions significantly improve the durability of molds in lampshade production. Through high-hardness, corrosion-resistant, and wear-resistant steel and advanced coating processes, the molds reliably withstand high-temperature cycles (120–200℃), UV aging, frequent opening and closing, and high-volume production conditions. This reduces common failure risks such as cavity corrosion, wear, cracking, and deformation, helping customers achieve longer mold life (over 2 million cycles) and lower overall maintenance costs.
We optimize the molding cycle through CAE mold flow simulation (with particular attention to thermal radiation and optical performance prediction), hot runner system design, efficient mold temperature control engineering, and 3D printed conformal cooling circuits, ensuring high-speed production capabilities on the customer's injection molding platform. Precise planning of gate location, venting system, and cooling system shortens cooling time, improves part dimensional stability, reduces internal stress and scrap rate, thereby directly increasing customer productivity, lowering per-unit cost, and ensuring long-term production consistency.
Based on the ISO 9001 certification system, GP Mold implements strict quality control and data recording at every stage, from raw material incoming inspection, mold processing, assembly and finishing, T1 mold trial verification, trial production to mass production. We conduct durability, filling, demolding, thermal stability, venting effect, and full-size functional verification (including light transmittance/haze testing, IP68 waterproof verification, 3000 hours of QUV accelerated aging, and 500 cycles of thermal shock) to ensure that the molds meet global optical and performance standards for lampshade products before formal delivery. We also support full-process traceability management of parts production and international logistics delivery capabilities.
