We review your automotive part drawings and 3D models to confirm functional tolerances and manufacturability. Our engineers help balance precision and cost for powertrain, chassis, and EV components.
Our team programs CNC machines, defines tooling and fixtures, and prepares inspection plans aligned with automotive PPAP requirements for prototype or volume production.
Components are machined on multi-axis equipment with stable processes suitable for repeated batches. Inline inspections ensure every lot meets automotive quality standards.
We coordinate heat treatment, plating, and surface finishing for wear and corrosion resistance. Each lot passes final dimensional and visual inspections before packing.
Parts are labeled, packed in returnable or disposable containers as required, and shipped according to your schedule. We support JIT and Kanban deliveries to keep production running smoothly.
From Design to Prototyping to Production, RuoChen Precision turns your ideas into reality with tailored, high-end machining solutions.
We machine a wide range of automotive alloys, from steels to aluminum and copper alloys. Finishes include anodizing, plating, passivation, and precision polishing to meet corrosion and appearance requirements.
