Detailed Description
GP Mold offers full-lifecycle injection mold development and molding solutions for global commercial vehicle manufacturers, focusing on meeting the mass production needs of high-strength, weather-resistant, vibration-resistant, and precision functional components such as exterior protection, interior functions, lighting optics, intake and exhaust cooling fluids, electrical protection and safety, NVH sound insulation and sealing, and internal structural support. We employ an engineering closed-loop development model, utilizing DFM (Design for Manufacturability) reviews, 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 3000T, 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 scale. This helps customers shorten verification cycles, reduce mold risks, and improve overall yield, with specific optimization for the harsh working conditions of commercial vehicle parts, including high temperatures in the engine compartment, outdoor weather resistance, vibration and impact, and media corrosion.
Specifications
GP Mold's commercial vehicle parts molds are designed with high strength, weather resistance (UV resistance), impact resistance, vibration fatigue resistance, chemical corrosion resistance, and flame retardant safety as core design objectives. They support various advanced mold architectures, including hot runner (including valve gate type), multi-cavity, stack molds, insert molding, two-color/overmolding, high-gloss transparent molding, and precision slide core pulling. Applications include exterior protection (such as front and rear bumpers, grilles, fender flares, side skirts, mudguards, door handle bases, pedal panels, toolbox/storage box housings, battery box housings), lighting optics (such as headlight lenses, taillight/turn signal covers, LED light guides, reflector cup supports, lamp housings, transparent camera protective covers, millimeter-wave radar covers), and intake/exhaust/cooling fluid systems (such as air filter housings, intake pipes, turbocharger intake diffusers, intercooler air ducts, radiator fan shrouds, cooling water three-way connectors, auxiliary water tank housings, fuel pump support housings, oil filler caps, windshield washer fluid reservoir housings, quick connectors). The applications include pipe fittings, oil and water pipe fixing clips, filter housings, water pump and fan brackets; interior controls (such as instrument panel frames and panels, center console housings, air conditioning vents, storage boxes, door panel linings, cup holders, seat adjustment covers, airbag covers, steering wheel switch module housings, gear shift panel knobs, light guide lenses, audio speaker grilles, sunroof control housings, interior reading light housings, snap-fit ​​connectors, cockpit trim strips, sun visor frames, passenger side glove box damping slides, and interior sealing strip base materials); electrical protection and safety (such as ECU housings, fuse box housings, relay bases, sensor mounting bases, camera and radar light protective covers, battery compartment protective covers, wiring harness fixing clips, insulation partitions, buttons and knobs, light guide lenses, temperature control overheat protection brackets, and power connector housings); and NVH sound insulation and sealing (such as motor and pump damping sleeves, sound insulation covers, anti-vibration hangers, sealing strip overmolding base materials, dust cover frames, pump end caps, and vibration damping support bases). 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 optical surfaces and sealing inserts, and smooth demolding. We provide independent engineering customized solutions for different modules of commercial vehicles, guaranteeing that the part molding quality meets stringent standards for low VOC, resistance to mud and sand abrasion, electrical safety, and millions of cycles of vibration fatigue.
Product Features
GP Mold prioritizes the use of high-hardness, corrosion-resistant, wear-resistant, and high-polish steels in commercial vehicle parts mold manufacturing, such as S136/S136H, 4Cr13/420, 718H/738H, H13, NAK80, etc. This is combined with controlled heat treatment (vacuum quenching/tempering/nitriding) and wear-resistant coating processes (PVD/TiN/CrN/hard chrome plating) to ensure excellent dimensional stability and cavity surface integrity even under long-term high-temperature and high-pressure injection molding cycles and exposure to humid and corrosive outdoor environments. The compatible molding materials system covers general plastics (PP, ABS, HDPE), engineering plastics (PC, PA6/PA66, POM, PBT, PC/ABS alloy, ASA, TPE/TPU, PPSU), and high-performance commercial vehicle-grade materials (glass fiber reinforced such as PP+EPDM/TD20/GF20-40%, PA66+GF30-50%, PBT+GF30%, weather-resistant and UV-resistant modified ASA, oil/coolant/urea/fuel resistant, high-temperature resistant 120–150°C such as PBT-GF/PPSU, low-temperature -40°C impact modified PP/PC, optical grade high-transparency PC/PMMA, low dielectric loss PC/PC+ABS, flame retardant V-0/V2 grade, low VOC, low odor, low fogging formulations, and flexible overmolding TPE/TPU/LSR inserts). 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 coatings, and beryllium copper inserts for localized enhanced cooling, ensuring streak-free optical lenses, scratch-resistant bumpers, and uniform and consistent light guides.

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 of mold cavities, cores, optical surfaces, sealing insert positioning, reflector frames, venting grooves, and parting lines. We have extensive experience in machining high-gloss headlight lenses, large bumper fascias, fiberglass-reinforced air filter housings, urea system connectors, and overmolded sealing strip molds, ensuring stable mold tolerances, uniform wall thickness, and balanced melt filling. This prevents air entrapment, burning, short shots, sink marks, warping, silver streaks, and weld line whitening, 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, weatherability regulations, vibration fatigue conditions, usage scenarios, and production capacity requirements. Our engineering team is involved from the initial design stage, providing DFM optimization suggestions, focusing on UV aging resistance, low VOC emissions, uniform mold temperature (±1℃ accuracy), and thermal expansion compensation to optimize the gating system and valve gate hot runner design. We independently customize the mold structure, mold temperature control circuit, cooling plan, ejection design, and surface treatment solutions, ensuring stable scalability of the mold during trial production and mass production.

Enhanced Durability

GP Mold's mold material system and heat treatment solutions significantly enhance the durability of molds in commercial vehicle parts production scenarios. Through high-hardness, corrosion-resistant, and wear-resistant steel and advanced coating processes, the molds reliably withstand high-temperature radiation cycles (120–150°C), humid and hot media erosion, millions of vibration impacts, and high-cycle mass production conditions. This reduces common failure risks such as cavity corrosion, wear, cracking, and deformation, helping customers achieve longer mold life (1 million–5 million cycles or more) 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 vibration fatigue and corrosion resistance prediction), hot runner system design, efficient mold temperature control engineering, and beryllium copper reinforced 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 unit costs, and ensuring consistent mass production over the long term.
