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, microchannels, sealing insert positioning, snap-fit structures, venting grooves, and parting lines. We possess extensive processing experience in multi-cavity ice trays, precision micro-holes in water distribution pipelines, low-temperature ice storage boxes, and overmolded sealing ring molds. This ensures stable mold tolerances, uniform wall thickness, and balanced melt filling, preventing air entrapment, short shots, sink marks, warping, stress whitening, and surface cracking, thereby significantly improving validation speed and mass production yield.
GP Mold employs a "one-project, one-solution" mold development strategy, providing precisely customized mold solutions based on customer product design, food contact regulations, low-temperature operating conditions, usage scenarios, and production capacity requirements. Our engineering team is involved from the initial design stage, providing DFM optimization suggestions, focusing on anisotropic shrinkage at low temperatures, uniform mold temperature (±1℃ accuracy), and optimized gating system and hot runner design. We independently customize the mold structure, mold temperature control circuit, cooling plan, ejection design, and surface treatment solutions, ensuring the mold has stable scalability during both trial production and mass production phases.
GP Mold's mold material system and heat treatment solutions significantly enhance the durability of molds in ice maker accessory production scenarios. Through high-hardness, corrosion-resistant, and wear-resistant steel and advanced coating processes, the molds reliably withstand thermal cycling, scale corrosion, frequent opening and closing, 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 and lower overall maintenance costs.
We optimize the molding cycle through CAE mold flow simulation (with particular attention to low-temperature crystallization and shrinkage prediction), hot runner system design, efficient mold temperature control engineering, and anti-corrosion conformal cooling circuits, ensuring the mold has high-cycle production capabilities on the customer's injection molding platform. Through precise planning of gate location, venting system, and cooling system, we can shorten cooling time, improve part dimensional stability, and reduce internal stress and scrap rate, thereby directly increasing customer productivity, lowering unit costs, and ensuring consistent long-term mass production.
GP Mold operates under an ISO 9001 certified system, implementing strict quality control and data recording at every stage, from raw material incoming inspection and mold processing to assembly, T1 mold trial verification, pilot production, and mass production. We conduct comprehensive testing on the molds, including durability, filling, demolding, thermal stability, venting effectiveness, and full-dimensional functional verification (including total migration testing, low-temperature impact resistance, and thermal cycling simulation), ensuring that they meet global food safety and performance standards for ice maker components before formal delivery. We also support full-process traceability management of parts production and international logistics delivery capabilities.
