Frequently Asked Questions (FAQ)
- What is the minimum order quantity (MOQ) for CNC machining of 304 stainless steel? – Our MOQ is flexible. For prototypes, we can accommodate as low as 1 piece. For mass production, typical MOQ is 500 pieces, but we can adjust based on your requirements.
- Can you achieve tighter tolerances than ±0.01mm? – Yes, tighter tolerances (e.g., ±0.005mm) are achievable depending on part geometry and size. Please contact us with your specific requirements for a feasibility evaluation.
- How do you ensure the quality of machined parts? – We implement a three-stage inspection: first article inspection (FAI) prior to production, in-process quality checks, and final dimensional inspection using CMM, micrometers, and surface testers. A full inspection report can be provided with each shipment.
- What surface finishes do you offer for 304 stainless steel? – Standard finishes include as-machined, bead blasting, passivation, and electropolishing. We can also apply additional coatings or treatments upon request.
- Do you provide design assistance or DFM (Design for Manufacturing) feedback? – Absolutely. Our engineering team reviews your CAD files and offers suggestions to improve manufacturability, reduce cost, and optimize performance. This service is included free of charge.
- What is the typical lead time for an order? – For standard orders, lead time is 7-15 working days after design approval and material confirmation. Rush orders can be expedited for an additional fee.
- Can you handle parts with complex internal features or secondary operations? – Yes, our multi-axis CNC machines can create complex internal cavities, undercuts, and threads. We also offer secondary services such as tapping, drilling, and assembly.
- How do you package and ship the parts? – Each part is individually wrapped with anti-corrosion paper, foam padding, and placed in a sturdy carton or wooden crate. We use bubble wrap and desiccant for moisture protection. Shipments are made via air or sea freight, with full tracking.
