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 blades, radial ribs, thin-walled areas (<1mm), micro-foaming structures, and parting lines. We have extensive processing experience with large impeller surfaces, fiberglass-reinforced triangular frames, precision distributor boxes, and dual-material door seal molds, ensuring stable mold tolerances, uniform wall thickness, and balanced melt filling. This prevents air entrapment, burning, short shots, sink marks, warping, fiberglass exposure, and stress concentration, 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, working condition simulations (high-temperature alkaline immersion/vibration fatigue), regulatory standards, usage scenarios, and production capacity requirements. Our engineering team is involved from the initial design stage, providing DFM optimization suggestions, focusing on weld line strength, uniform mold temperature (±1℃ accuracy), and multi-scale simulation optimization of gating systems and venting designs. We independently customize mold structure, mold temperature control circuits, cooling planning, ejection design, and surface treatment solutions, ensuring stable and scalable capabilities during both trial and mass production phases.
The GP Mold mold material system and heat treatment solution significantly improve the durability of molds in washing machine parts production. Through the use of high-hardness, corrosion-resistant, and wear-resistant steel and advanced coating processes, the molds reliably withstand high-temperature cycles (80-95℃), fiberglass-reinforced abrasion, alkaline corrosion, and multi-ton injection molding pressures. 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 molding cycles through CAE mold flow simulation (with a focus on fiber orientation 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 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 effectiveness, and full-scale functional verification (including thermal shock, salt spray corrosion, and millions of opening and closing cycles) to ensure that the molds meet global regulations and performance standards for washing machine parts before formal delivery. We also support full-process traceability management and international logistics delivery capabilities for part production.
