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 over mold cavities, cores, sealing inserts, microchannels, snap locks, vents, and parting lines. We have extensive processing experience in high-mirror vacuum chamber covers, overmolded sealing strips, heat-resistant sealing support bases, and glass fiber reinforced pump impeller molds, ensuring stable mold tolerances, uniform wall thickness, and balanced melt filling, preventing air entrapment, scorching, short shots, sink marks, warping, yellowing resistance, and negative pressure deformation, thereby significantly improving validation speed and mass production yield.
GP Mold adopts an "engineering one-case-per-project" mold development strategy, providing precisely customized mold solutions based on customer product design, food safety regulations, negative pressure 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 valve gate hot runner design for negative pressure stress, uniform mold temperature (±1℃ accuracy), and thermal expansion compensation. 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 both trial production and mass production phases.
GP Mold's mold material system and heat treatment solutions significantly improve the durability of molds in vacuum packaging machine parts production scenarios. Through high-hardness, corrosion-resistant, and wear-resistant steel and advanced coating processes, the molds reliably withstand humid heat negative pressure cycles, detergent corrosion, mechanical friction, and high-cycle mass production conditions, reducing common failure risks such as cavity corrosion, wear, cracking, and deformation, helping customers achieve longer mold life (over one million cycles) and lower overall maintenance costs.
We optimize the molding cycle through CAE mold flow simulation (with particular attention to negative pressure deformation and corrosion resistance prediction), hot runner system design, efficient mold temperature control engineering, and beryllium copper reinforced cooling circuits, ensuring 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, reduce internal stress and scrap rate, thereby directly increasing customer productivity, lowering unit costs, and ensuring consistent long-term mass production.
GP Mold, based on the ISO 9001 certification system, implements strict quality control and data recording at every stage, from raw material entry and mold processing to assembly, T1 mold trial verification, pilot production, and mass production. We conduct durability, filling, demolding, thermal stability, venting effect, and full-size functional verification (including total migration testing, detergent corrosion resistance, and negative pressure cycle simulation) to ensure that the molds meet global food safety and performance standards for vacuum packaging machine parts before formal delivery. We also support full-process traceability management of parts production and international logistics delivery capabilities.
