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, complex waveguide surfaces, insert positioning holes, reinforcing rib structures, venting grooves, and parting lines. We possess extensive experience in machining large integrated housings, glass fiber reinforced speaker frames, heat-resistant voice coil bobbins, and precision horn molds, ensuring stable mold tolerances, uniform wall thickness, and balanced melt filling, preventing air entrapment, burning, short shots, sink marks, warping, and glass fiber exposure. This significantly improves validation speed and mass production yield.
GP Mold employs a "one-project, one-solution" mold development strategy, providing precisely customized PA injection mold solutions based on customer product design, acoustic performance requirements, thermal load conditions, operating environment, and production capacity needs. Our engineering team is involved from the initial design stage, providing DFM optimization suggestions, focusing on optimizing the gating system and venting design for PA's hygroscopic properties. We independently customize the mold structure, mold temperature control circuits, cooling planning, ejection design, and surface treatment solutions, ensuring stable and scalable performance during both trial and mass production phases.
GP Mold's mold material system and heat treatment solutions significantly enhance the durability of molds in PA audio production scenarios. Through high-hardness wear-resistant steel and advanced coating processes, the molds reliably withstand the high wear, high-temperature cycles, and frequent opening and closing conditions of glass fiber reinforced PA, reducing common failure risks such as cavity corrosion, wear, cracking, and deformation. This helps customers achieve longer mold life (up to millions of cycles) and lower overall maintenance costs.
We optimize molding cycles through CAE mold flow simulation (with particular attention to PA crystallization behavior and warpage prediction), hot runner system design, efficient mold temperature control engineering, and precise cooling circuit optimization, 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, and reduce internal stress and scrap rate, thereby directly increasing customer productivity, lowering unit costs, and ensuring consistent mass production in the long term.
GP Mold implements strict quality control and data recording at every stage, from raw material incoming inspection and mold processing to assembly, T1 mold trial verification, and mass production. We conduct durability, filling, demolding, thermal stability, venting effect, and full-size functional verification of the molds to ensure they meet the high-strength, heat-resistant, and acoustic performance standards required for professional audio equipment before final delivery. We also support full-process traceability management of parts production and international logistics delivery capabilities.
