Kunshan Diamond Precision Mold designs and manufactures custom die-cast components for shifter mechanisms and interior trim. We provide OEM/ODM support from DFM and mold flow through tooling, casting, machining, finishing, and measurement. Zinc and aluminum alloys are selected to meet stiffness, weight, wear, EMI, and cosmetic targets. Programs cover manual, automatic, and shift-by-wire systems with reliable quality, short sampling cycles, and export-ready project management.
Typical parts include shifter housings and bases, selector forks and detent plates, actuator and sensor housings, paddle shifters, cable ends, brackets, knobs, and trim bezels. Aluminum (A380/ADC12) suits structural brackets and bases where stiffness and mass are critical. Zinc (Zamak 3/5) enables crisp detail and plating-ready surfaces for touchpoints and compact housings. For plating references and small interior components, see our automotive zinc alloy products.
Use the guide below to choose an alloy for your shift components.
| Criteria | Aluminum (A380/ADC12) | Zinc (Zamak 3/5) |
|---|---|---|
| Strength-to-weight | High stiffness, low mass; ideal for housings/brackets | Higher density; excellent for compact parts |
| Detail & thin walls | Good; more draft/wall may be needed | Excellent fine detail and thin walls |
| Thermal/EMI | Better thermal dissipation | Superior EMI shielding |
| Finishing | Chromate, paint, selective plating/PVD | Chrome/satin chrome, PVD, nickel |
We engineer stable interfaces, bosses, and guides for precise assembly. Aluminum provides a strong stiffness-to-weight ratio; zinc supports fine cosmetic detail for visible bezels and frames. Surface classes and chrome, satin chrome, PVD, or nickel finishes are managed for uniform appearance.
Selector forks and detent plates require strength, wear resistance, and accurate engagement faces. We plan machining allowances for critical bores and slots, and verify datums to keep shift feel consistent over vehicle life.
Our integrated model combines engineering, in-house toolmaking, aluminum and zinc die casting, CNC machining, finishing, and inspection under one roof. Annual output includes about 300 sets of molds and up to 60 million die-cast parts across a 9,000–10,000 m² facility. Aluminum presses in the 350–500-ton range cover varied sizes. Tight parameter control, measurement planning, and cosmetic process management deliver consistent fit and finish. Explore our end-to-end die casting capabilities.
Early collaboration reduces risk and cost. Share drawings, volumes, target materials and finishes, CTQ features, and test standards. We support practical wall thickness, draft, ribbing, and parting line planning to protect cosmetic zones.
RFQ: CAD + drawings; target alloy (A380/ADC12 or Zamak 3/5); finish and volumes.
Tolerancing: Define as-cast vs. machined features; align datums to assembly.
Quality: Appearance criteria, corrosion targets, and packaging for plated parts.
