Automotive Drive Gears Die Casting Parts include gear wheels, planetary carriers, and motor or gearbox housings produced in aluminum and zinc alloys. As an OEM/ODM partner, Kunshan Diamond Precision Mold Co., Ltd. supports your program from DFM and mold flow analysis to tooling, casting, machining, measurement, and finishing.
With 20+ years in molds and nearly 15 years in zinc and aluminum production, we deliver repeatable accuracy for gear components. Capacity spans about 300 mold sets and 60 million parts annually. Aluminum die casting machines (350–500 tons) cover medium-size housings and carriers. Explore our DFM and mold flow analysis capabilities to see how we engineer quality into every step.
Zamak 3/5 enables fine tooth details and low noise for HVAC, seat, and window regulator drives. We provide plating or chromate finishes and selective post-machining for tight fits. View related parts in our automotive zinc alloy products.
Aluminum carriers and gearbox or motor housings combine stiffness, thermal conductivity, and weight savings. Critical bores, bearing seats, and datum faces are machined for alignment and NVH control.
Alloy selection balances load, temperature, environment, and cost. Aluminum (e.g., ADC12/A380) suits carriers and housings; zinc (Zamak 3/5) suits small gear wheels and worm or spur drives. Common finishes include chromate conversion, anodizing for aluminum, and plating for zinc. Post-casting machining is applied to bores, gear teeth, and datum faces to meet assembly tolerances.
Effective DFM addresses draft, wall thickness, ribbing, and parting line placement to protect tooth geometry. We optimize gating, cooling, and venting based on mold flow results. Quality control includes CMM inspection, defined datum strategies, and documented in-process checks for stable capability.
We scale from prototypes and pilot runs to mass production with transparent scheduling. Short first-article lead times help validate geometry and function quickly. Strong project management coordinates tooling, casting, machining, finishing, and inspection.
