Automotive

Balancing Performance, Cost, and Production Scale

Automotive components must operate stably under mechanical stress, vibration, high temperature, and long-term use, while meeting strict cost targets and increasing production volume requirements.

Core Constraints for Component Development

Strict Tolerance Control

Stable and Durable Performance

Batch Consistency

Material Traceability

Full-Process Compliance

Fast Delivery Cycle

Engineering-Driven · Full-Cycle Support for Automotive Projects

Surface Treatment Processes

Anodizing

Applied to aluminum alloy components, enhancing corrosion resistance and wear resistance, available in custom colors for automotive interior and exterior parts.

Hard Anodizing

Increases the surface hardness of aluminum parts, suitable for high-wear components such as chassis brackets and motor accessories in automotive systems.

Black Oxide Coating

Used for carbon steel and alloy steel parts, providing rust and corrosion resistance, widely applied to automotive fasteners, shafts, and chassis components.

Hot-Dip Galvanizing

Forms a protective zinc layer on steel parts, with excellent corrosion resistance, suitable for automotive exterior structural parts and undercarriage components.

Electroplating (Zinc/Nickel/Chrome)

Improves surface finish and corrosion resistance; chrome plating is used for decorative parts, zinc-nickel plating for high-corrosion areas.

High-Gloss Polishing

Applied to mold cavities and automotive appearance parts, achieving a mirror-like finish to ensure the surface quality of injection-molded and machined parts.
