Client: Japanese Aftermarket Auto Parts Manufacturer
Industry: Automotive
Location: Japan
At ZC Precision, we recently partnered with a Japanese aftermarket auto parts manufacturer to produce high-quality, precision-machined aluminum half-circle parts. These parts were essential for enhancing automotive performance and meeting stringent industry standards.
Client Requirements

Precision: High tolerance levels for perfect fit.
Surface Finish: Smooth, flawless surface for aesthetic and functional excellence.
PET Certification: Compliance with environmental and safety standards.
Material Analysis Report: Verified by an authorized lab to ensure material consistency and performance.
Technical Challenges
Machining half-circle aluminum parts presents unique challenges, including:
1.Concentricity: Ensuring that the concentricity of the parts is maintained to meet the required precision.
2.Plane Surface Deformation: Preventing deformation of the plane surface during the machining process to ensure a flat and even finish.
Solutions to Technical Challenges
3.Concentricity:
Precision Fixturing: Use high-precision fixtures to hold the parts securely in place during machining. Custom fixtures can be designed to ensure the part is perfectly aligned and stable.
4.Slow and Steady Approach: Opt for slower feed rates and spindle speeds when finishing critical dimensions to maintain tight tolerances.
Understanding the PET Certificate
A PET (Product Environmental Testing) Certificate is a crucial document that verifies a product’s compliance with environmental and safety standards.
ZC Precision demonstrates its ability to deliver high-quality CNC milled aluminum parts for the aftermarket auto parts industry. Our commitment to precision, quality, and regulatory compliance, including PET certification, ensures we meet the most demanding client requirements.
