Explore our portfolio of precision-machined prototypes and high-durability production parts manufactured for global automotive tier suppliers and OEMs. Each component reflects our strict adherence to rigid dimensional tolerances and strict quality verification standards.








We manufacture automotive components strictly adhering to ISO 9001:2015 quality systems and automotive-grade standards. We strictly implement PPAP (Production Part Approval Process) protocols to ensure every batch meets rigid automotive tolerance and safety requirements.
We specialize in high-precision CNC machining and sheet metal fabrication for powertrain components, EV battery housings, transmission gears, suspension brackets, custom sensor enclosures, heat sinks, and lightweight interior structural parts.
Yes. We source certified raw materials—including aircraft/automotive grade aluminum (6061-T6, 7075-T6), high-strength stainless steel, titanium, and engineering plastics (POM, PEEK). Every order comes with Material Test Reports (MTRs), RoHS/REACH compliance certificates, and heat lot numbers for complete batch traceability.
We provide end-to-end manufacturing support. You can start with rapid prototyping (1-10 units) using 5-axis CNC machining for initial fit & functional testing, and smoothly transition to low-to-high volume production (10,000+ units) with optimized unit costs and dedicated fixtures.
Utilizing multi-axis CNC machining centers, we routinely maintain tight tolerances down to ±0.001” (±0.025 mm) for critical bearing seats, engine blocks, and seal grooves. Complex 3D surfaces and curved EV battery cold plates are 100% verified via CMM inspection.
We offer automotive-grade surface finishing tailored to severe working conditions, including Hardcoat Anodizing (Type III), Powder Coating, Passivation, Electroplating (Nickel/Zinc), and E-coating (Electrodeposition) for maximum corrosion resistance and durability.
Once we receive your design files, our senior manufacturing engineers will manually perform a comprehensive DFM review and deliver an accurate, optimized quote within 24 hours.
