Detailed Description
GP Mold offers full lifecycle injection molding development and manufacturing solutions for global shredder equipment manufacturers, focusing on meeting the mass production needs of high-wear, high-strength, and precision functional components such as paper feed trays, protective housings, internal structural brackets, function buttons, waste bin assemblies, blade protection covers, drive system parts, and caster adjustment pads. We employ a closed-loop engineering development model, utilizing DFM (Design for Manufacturability) review, precision mold structure design, mold flow simulation analysis, cooling and ejection system optimization, and high-standard CNC/EDM/wire cutting manufacturing processes to ensure high-cycle production stability and micron-level fit reliability. GP Mold has the capability to support injection molding equipment from 100T to 1600T, and can provide aluminum and high-grade steel mold solutions, adapting to production transitions from small-batch verification to tens of millions of units in capacity. This helps customers shorten verification cycles, reduce mold risks, and improve overall yield, with specific optimization for the high-speed operation, continuous load, and safety requirements of shredder parts.
Specifications
GP Mold's shredder accessory molds are designed with wear resistance, structural strength, dimensional stability, and safety protection as core objectives. They support various advanced mold architectures, including hot runner, multi-cavity, stack molds, insert molding, two-color/multi-color overmolding, precision gear molding, and thin-wall structure molding. These molds are suitable for paper trays and guides, housings and protective covers (such as main casings, top covers, side panels), internal structural brackets (such as motor mounts, gearbox housings, blade shaft support frames), function buttons and control panels (such as power switches, gear selection buttons, reverse buttons), waste bin components (such as the bin body, handle, and latching mechanism), blade group protective covers and safety baffles, transmission system parts (such as gears, worms, cams), and wheels and adjustable feet. Mold manufacturing tolerances are stably controlled within ±0.01–0.02mm, ensuring reliable critical assembly fit, uniform wall thickness, controllable weld line strength, precise molding of tooth profiles and sealing edges, and smooth demolding. We provide independent engineering customization solutions for different shredder components, guaranteeing that part molding quality meets the stringent requirements of high-speed vibration, impact resistance, safety standards, and long-term reliability.
Product Features
GP Mold prioritizes the use of high-hardness, wear-resistant, corrosion-resistant, and high-polish steels in the manufacturing of shredder accessory molds, such as S136H, NAK80, 2344ESR (H13), P20, 2738, FDAC, ASP-23, and 2316H. This is combined with controlled heat treatment (quenching/tempering/nitriding/cryogenic treatment) and wear-resistant coating (PVD/TiN/CrN) processes to ensure that the molds maintain excellent dimensional stability and cavity surface integrity even under long-term high-temperature and high-pressure injection molding cycles and abrasive environments involving glass fiber reinforced materials. The compatible molding materials system covers general plastics (PP, ABS, HDPE), engineering plastics (PC/ABS alloy, PA6/PA66, POM, PA12, TPU), and high-performance shredder-grade materials (glass fiber reinforced materials such as PA6+GF30%, PA66+GF25%, flame-retardant V-0 grade, impact-resistant and low-temperature modified materials, high-flow thin-wall formulations, self-lubricating POM/PA12, wear-resistant reinforced and mechanically interlocking structure compatible materials). Mold surface treatment strictly follows SPI/SPE standards (A-1/A-2 grade mirror high-gloss, B grade semi-gloss, C grade matte polishing), and supports VDI texture, laser etching, sandblasting, chrome plating, mirror polishing, anti-stick coating, and precision gear grinding to ensure consistent smoothness of the paper guiding surface, wear-resistant drive gear profiles, and safe protective surfaces.

Exceptional Precision

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, precision gear profiles, insert positioning, reinforcing rib structures, venting grooves, and parting lines. We have extensive experience in processing precision transmission gears, glass fiber reinforced structural brackets, large thin-walled housings, and two-color operating panel molds, ensuring stable mold tolerances, uniform wall thickness, and balanced melt filling, preventing air entrapment, burning, short shots, sink marks, warping, glass fiber exposure, and weld line displacement, thereby significantly improving validation speed and mass production yield.

Customization Capabilities

GP Mold adopts a "one-project, one-solution" mold development strategy, providing precisely customized mold solutions based on customer product design, safety standards, load conditions, usage scenarios, and production capacity requirements. Our engineering team is involved from the early design stages, providing DFM optimization suggestions, focusing on avoiding weld lines in stress areas, balanced mold temperature (±2℃ accuracy), and optimized venting and gating systems. We independently customize the mold structure, mold temperature control circuits, cooling planning, ejection design, and surface treatment solutions, ensuring stable and scalable capabilities for the mold during both trial and mass production phases.

Enhanced Durability:

GP Mold's mold material system and heat treatment solutions significantly enhance the durability of molds in shredder parts production scenarios. Through high-hardness, wear-resistant, and corrosion-resistant steel and advanced coating processes, the molds reliably withstand high-temperature cycles, glass fiber reinforced wear, mechanical vibration, and frequent opening and closing conditions, reducing common failure risks such as cavity corrosion, wear, cracking, and deformation, helping customers achieve longer mold life (≥500,000 cycles in mass production) and lower overall maintenance costs.

Efficient Production

We ensure high-cycle production capabilities on our customers' injection molding platforms through CAE mold flow simulation (with a particular focus on tooth profile filling and warpage prediction), hot runner system design, efficient mold temperature control engineering, and multi-layer conformal cooling circuit optimization. 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 per-unit costs, and ensuring consistent mass production over the long term.

Quality Assurance

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 effect, and full-dimensional functional verification of the molds to ensure they meet global safety and performance standards for shredder parts before formal delivery. We also support full-process traceability management of parts production and international logistics delivery capabilities.
