Frequently Asked Questions
How do different surface treatments affect corrosion resistance?
Anodizing creates a protective oxide layer ideal for aluminum parts in outdoor environments. Zinc plating offers economical corrosion protection for steel. Nickel plating provides superior wear and corrosion resistance. PVD coatings deliver exceptional hardness and chemical resistance. We recommend treatments based on specific environmental conditions and performance requirements.
What precision levels can your CNC machining achieve before surface treatment?
Our CNC machining centers achieve ±0.01mm tolerances with surface finishes to Ra 1.6. We account for coating thickness in machining dimensions to ensure final parts meet assembly tolerances post-treatment. Critical features can be masked during treatment to preserve machined accuracy.
Do you provide PPAP documentation and inspection reports?
Yes, complete PPAP packages include dimensional reports, material certifications, coating thickness measurements, salt spray test results, and surface finish analysis. We provide full traceability documentation meeting automotive and medical device industry standards.
What are typical lead times for samples versus production quantities?
Sample parts with surface treatment typically require 2-3 weeks including machining, treatment, and testing. Production quantities depend on volume and complexity but generally range from 3-6 weeks. Expedited options available for urgent requirements with advance coordination.
