Frequently Asked Questions (FAQ)
-
Q: What is a Mill Test Report and why do you supply it?
A: A Mill Test Report (MTR) is a quality assurance document that certifies the material's chemical composition and mechanical properties. We supply it with every shipment to ensure full traceability and compliance with industry standards. -
Q: Do you perform 100% inspection on all parts?
A: Yes, we conduct 100% dimensional and visual inspection on every stamped and welded part. For critical dimensions, we use CMM and gauges. Weld integrity is tested by visual inspection and, if required, by destructive or non-destructive testing. -
Q: Can you handle complex geometries with tight tolerances?
A: Absolutely. Our stamping dies and welding fixtures are custom designed to achieve tolerances of ±0.1 mm or better. We have experience with intricate brackets, enclosures, and structural components. -
Q: What materials can you stamp and weld?
A: We work with carbon steel, stainless steel (304, 316), aluminum, copper, brass, and galvanized steel. All materials are sourced from certified suppliers and accompanied by MTR upon request. -
Q: What is your typical lead time for custom parts?
A: For prototypes, 7–15 days; for production orders, 15–30 days depending on quantity and complexity. We can expedite for urgent projects. -
Q: Do you offer surface finishing options?
A: Yes, we offer deburring, zinc plating, powder coating, galvanizing, and passivation. Please specify your requirements, and we will recommend the best option. -
Q: What is the minimum order quantity (MOQ)?
A: For standard parts, MOQ is 1000 pcs. For prototypes, we accept small quantities (50–200 pcs) to support your product development. -
Q: How do you ensure consistent quality across high-volume production?
