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, involute tooth profiles, sealing insert positioning, thin-walled reinforcing ribs, venting grooves, and parting lines. We have extensive experience in machining precision limiters, multi-slide handle structures, overmolded sealing corner brackets, and large screen window frame molds, ensuring stable mold tolerances, uniform wall thickness, and balanced melt filling, preventing air entrapment, burning, short shots, sink marks, warping, glass fiber exposure, and weld line whitening, thereby significantly improving validation speed and mass production yield.
GP Mold adopts an "engineering one-project-one-solution" mold development strategy, providing precisely customized mold solutions based on customer product design, weather resistance regulations, load-bearing creep conditions, usage scenarios, and production capacity requirements. Our engineering team is involved from the initial design stage, providing DFM optimization suggestions, focusing on multi-physics coupling simulation, uniform mold temperature (±0.5℃ accuracy), and thermal expansion compensation to optimize the gating system and multi-point hot runner design. We also independently customize the mold structure, mold temperature control circuit, cooling plan, ejection design, and surface treatment solutions, ensuring stable scalability of the mold during trial production and mass production.
GP Mold's mold material system and heat treatment solutions significantly enhance the durability of molds in window and door accessory production scenarios. Through high-hardness, corrosion-resistant, and wear-resistant steel and advanced coating processes, the molds reliably withstand humid and cold condensation cycles, dust and abrasive particle erosion, millions of opening and closing impacts, and high-cycle mass production conditions, reducing common failure risks such as cavity corrosion, wear, cracking, and deformation. This helps customers achieve longer mold life (over 1.5 million cycles) and lower overall maintenance costs. High-Efficiency Production: We optimize molding cycles through CAE mold flow simulation (with a particular focus on creep prediction and fatigue simulation), hot runner system design, efficient mold temperature control engineering, and 3D printed conformal cooling circuit optimization, ensuring high-speed production capabilities on our clients' injection molding platforms. Through precise planning of gate location, venting systems, and cooling systems, we shorten cooling times, improve part dimensional stability, reduce internal stress and scrap rates, thereby directly increasing customer productivity, lowering unit costs, and guaranteeing consistent long-term mass production.

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, pilot production to mass production. We conduct durability, filling, demolding, thermal stability, venting effect, and full-size functional verification of the molds (including 3000 hours of QUV ultraviolet irradiation, 1000 hours of salt spray testing, 2000 high and low-temperature cycles, and 100,000 opening and closing life tests) to ensure that they meet global regulations and performance standards for window and door hardware products before formal delivery. We also support full-process traceability management of parts production and international logistics delivery capabilities.
