All automotive precision parts are packaged in custom-designed, anti-corrosion export-grade wooden cases or cartons to prevent any damage during transit.
FAQ
Swiss-type CNC machining feeds the bar stock through a guide bushing, allowing the tool to cut precisely near the bushing. This provides unparalleled support, making it ideal for manufacturing long, slender, and micro-precision automotive components (like shafts and pins) with tight tolerances, while minimizing deflection and vibration compared to conventional CNC turning.
We implement rigorous SPC (Statistical Process Control) throughout the production cycle. By utilizing Japanese Star CNC lathes and German/Japanese imported testing instruments, we conduct first article inspection (FAI), in-process inspections, and final random sampling. This guarantees that every batch meets the strict PPAP (Production Part Approval Process) standards required by the automotive industry.
Yes. Our 30+ years of experience and advanced equipment allow us to process a wide range of automotive-grade materials. We have optimized cutting parameters for tough alloys like SCM440 (chrome-molybdenum steel) and 12L14 (free-cutting steel), ensuring excellent surface finish and tool life without compromising material integrity.
We offer a comprehensive range of surface treatments tailored for automotive environments, including zinc-nickel alloy plating (for high corrosion resistance), black oxide coating, anodizing (for aluminum parts), carburizing, and quenching. These treatments enhance the wear resistance, fatigue strength, and corrosion protection of the final components.
For new custom projects, the lead time for the first sample (prototyping) is generally 7-15 days, depending on the complexity of the geometry and the need for custom tooling. Once the sample is approved, the lead time for mass production typically ranges from 20 to 35 days, heavily dependent on the order volume and surface treatment requirements.
Absolutely. We adhere to the "Quality Foremost" principle. Every shipment of CNC automotive precision parts comes with a Mill Test Certificate (MTC) from the raw material supplier, as well as an internal dimensional inspection report and FAI (First Article Inspection) report, ensuring full traceability and quality assurance for our clients.
