Engine housings, transmission cases, ECU enclosures and structural brackets for EV, HEV and ICE platforms — produced on IATF 16949 lines.
Hiyet supplies powertrain and chassis castings for EV, hybrid and conventional vehicles. Our flagship 5052-T5 motor protection shells combine excellent strength-to-weight with full corrosion resistance, safeguarding traction motors against impact, moisture and road chemicals.
Transmission housings cast from A356-H32 deliver the toughness needed for repeated power-transfer cycles, while ADC12 die-cast ECU enclosures provide tight tolerances and EMC-friendly geometry. Every program is validated through IMDS, PPAP and 100% dimensional CMM inspection on critical features.
Our automotive line is staffed by engineers who came from tier-1 suppliers — they know what your customers will ask in the audit. Every line is APQP-managed, with PFMEAs reviewed before tooling release. Material traceability is at heat-number level, and we ship CMM and material certs with every container, no surcharge.
We typically support cost-down workshops on mature programs — 8–15% savings are common through wall-thickness optimization, runner re-design, or alloy substitution to lower TCO without compromising performance.
Yes. Our automotive QA team prepares full IMDS data sheets and CDX submissions as part of the PPAP package, including third-party material analysis if needed.
Level 1 = 1 week post-production; Level 3 with full capability study = 3–4 weeks post-trial. Level 5 on-site reviews are scheduled as needed.
Yes — brass nuts, steel sleeves, helicoils and oil-resistant thread inserts are routinely cast in to reduce secondary machining.
Yes. Rapid sand-cast or 3D-printed sand-mold prototypes ship in 10–14 days; aluminum/silicone bridge tools for 50–500 pcs in 3 weeks.
Send us your STEP / IGES / DWG / PDF and a senior engineer will respond with DFM feedback, tooling cost and unit price within two business days.
