Frequently Asked Questions
Q1: What's the minimum batch size for CNC automotive parts?
A1: We can start from a single prototype part and scale up to thousands for mass production.
Q2: Can you provide material certificates and inspection reports?
A2: Yes. All shipments include full QC reports, and material certifications are available upon request.
Q3: What if my part requires multiple processes (e.g., machining + coating)?
A3: We offer integrated services including machining, surface finishing, assembly, and packaging--everything in-house or through vetted partners.
Q4: Are you capable of reverse engineering existing automotive parts?
A4: Yes. With 3D scanning and CAD services, we can reverse engineer and manufacture replacement or improved parts.
Q5: Do you accept urgent or rush orders?
A5: We offer expedited services for urgent prototyping, with 5-7 day turnaround depending on complexity.
