GP Mold leverages advanced mold manufacturing and high-tonnage injection molding capabilities to provide global companies with customized plastic parts solutions that are high-precision, high-strength, and highly consistent.
These molds are suitable for components such as housings and enclosures (e.g., multimedia speakers, Bluetooth speakers, Soundbar housings), protective grilles, diaphragms/cones, voice coil formers, speaker frames/brackets, sound guides/bass reflex tubes, terminal boards, knobs and buttons, heat dissipation grilles, and feet. Mold manufacturing tolerances are stably controlled within ±0.02–0.05mm, ensuring reliable critical assembly fit, uniform wall thickness, controllable weld line strength, precise molding of acoustic vents, and smooth demolding. We provide independent engineering customized solutions for different audio scenarios, guaranteeing that part molding quality meets the stringent acoustic and structural standards of professional audio, consumer audio, and portable devices.

Key messages paired with visuals to communicate capabilities.
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, acoustic holes, snap-fit structures, insert positions, sealing surfaces, and parting lines. We possess extensive processing experience in integrated speaker grilles, diaphragm molding, two-color knobs, and complex curved sound guide molds, ensuring stable mold tolerances, uniform wall thickness, and balanced melt filling, preventing air entrapment, short shots, sink marks, warping, and batch-to-batch appearance variations, 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, acoustic requirements, usage scenarios, and production capacity needs. Our engineering team is involved from the initial design stage, providing DFM optimization suggestions to ensure product structure is adapted to high-cycle injection molding production. We independently customize mold structure, gating systems, cooling plans, ejection designs, and surface treatment solutions, ensuring the mold has stable scalability during trial production and mass production phases.
GP Mold's mold material system and heat treatment solutions significantly enhance the durability of molds in audio production scenarios. Through high-hardness steel and advanced coating processes, the molds reliably withstand high-temperature cycles, wear from glass fiber reinforced materials, and other conditions, reducing common failure risks such as cavity corrosion, wear, cracking, and deformation, helping customers achieve longer mold life and lower overall maintenance costs.
We optimize molding cycles through CAE mold flow simulation, hot runner system design, and efficient cooling engineering, ensuring high-speed production capabilities on the customer's injection molding platform. Precise planning of gating and cooling systems shortens cooling time, improves part dimensional stability, and reduces warping and scrap rates, directly increasing customer productivity, lowering per-unit costs, and ensuring consistent long-term mass production.
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 trial molding verification, trial production to mass production. We conduct durability, filling, demolding, thermal stability, and full-dimensional functional verification of the molds to ensure they meet global standards for audio-grade products before formal delivery. We also support full-process traceability management of parts production and international logistics delivery capabilities.
