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, precision threads, insert positioning holes, sealing ring grooves, reinforcing rib structures, venting grooves, and parting lines. We have extensive experience in processing large distribution boxes, high-fiber reinforced control cabinets, precision waterproof connectors, and molds with core-pulling mechanisms, ensuring stable mold tolerances, uniform wall thickness, and balanced melt filling. This prevents air entrapment, burning, short shots, sink marks, warping, glass fiber exposure, and weld line displacement, significantly improving validation speed and mass production yield.
GP Mold employs a "one-project, one-solution" mold development strategy. Based on customer product design, electrical safety regulations, IP protection ratings, operating environment, and production capacity requirements, we provide precisely customized mold solutions. Our engineering team is involved from the initial design stage, providing DFM optimization suggestions, focusing on avoiding weld lines in high-voltage areas, achieving balanced mold temperature (±2℃ accuracy), and optimizing the gating system for venting. We independently customize the mold structure, temperature control circuits, cooling planning, ejection design, and surface treatment solutions, ensuring stable and scalable performance during both trial and mass production.
The GP Mold mold material system and heat treatment solutions significantly improve the durability of molds in electrical box and cable box production scenarios. Through high-hardness, wear-resistant, and corrosion-resistant steel and advanced coating processes, the molds reliably withstand high-temperature cycles, fiberglass reinforcement abrasion, flame retardant corrosion, and multi-ton injection molding pressures, reducing common failure risks such as cavity corrosion, wear, cracking, and deformation. This helps customers achieve longer mold life (mass production ≥ 500,000 cycles) and lower overall maintenance costs.
We ensure high-cycle production capabilities on our customers' injection molding platforms through CAE mold flow simulation (with a particular focus on glass fiber orientation and warpage prediction), hot runner system design, efficient mold temperature control engineering, and optimized cooling circuits. Through precise planning of gate locations, 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 ensuring consistent mass production over the long term.
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-dimensional functional verification of the molds to ensure they meet global safety and performance standards for electrical and cable box products before formal delivery. We also support full-process traceability management of parts production and international logistics delivery capabilities.
