Automotive Lock Die Casting Parts from Kunshan Diamond Precision Mold Co., Ltd. are engineered for durable, precise vehicle lock systems across ICE and EV platforms. We support zinc and aluminum alloy parts from DFM and mold flow to tooling, production, finishing, measurement, and quality control. Explore our die casting and mold capabilities to align your requirements with our process strengths.
We produce door latch and striker housings, lock cylinder shells, steering column lock parts, and trunk or glovebox components. Designs include bosses, threads, hinge points, detents, and interfaces for actuators, cables, and sensors. For zinc-intensive programs, review our related automotive zinc alloy die-cast products.
| Material | Best For | Typical Finishes |
|---|---|---|
| Zamak 3 | Precision shells, small brackets, actuator interfaces | Nickel, chrome, satin chrome, color zinc, PVD, chromate |
| Zamak 5 | Higher-strength housings and latch components | Chrome plated, nickel, color zinc, PVD |
| Aluminum alloys | Lightweight covers and larger housings | Chromate conversion, paint or powder coat |
Finish stacks are matched to cosmetic and corrosion targets, with masking or selective plating where needed.
Our team applies DFM and mold flow analysis to optimize gating, venting, and ejection for thin-walled lock geometries. Casting parameters are controlled to reduce porosity and protect precision bores, ribs, and threads. Aluminum parts run on 350–500T machines; zinc cells are tuned for short cycles and consistent release. Quality covers incoming materials, in-process checks, and final inspection. FAI and documentation can be provided per your requirements.
We deliver assembly-ready parts with trimming, deburring, CNC machining, drilling, tapping, and surface preparation. Datums and gauge plans support functional fits and repeatability.
Include these details in your RFQ to accelerate DFM and pricing:
Material grade and any inserts or overmolding.
Critical dimensions, GD&T, and datum scheme.
Wall thickness, draft, and thread strategy (cast vs. post-tapped).
Finish stack, cosmetic criteria, and corrosion targets.
Validation plan, sample quantities, and reporting format.
