Frequently Asked Questions
Why choose 316L instead of 304 for automation parts?
316L offers better corrosion resistance compared to 304 stainless steel, making it ideal for humid environments, chemical washdown areas, food-grade applications, or outdoor automation equipment where exposure to moisture or chemicals is a concern.
Can you hold shaft concentricity and runout tolerance?
Yes. We inspect runout, concentricity and critical fit dimensions using CMM (Coordinate Measuring Machine) and precision gauges to ensure all your critical tolerances are met before shipping.
Do you support small batch prototype orders?
Yes, our MOQ starts from 1 piece for prototyping. We support small trial orders to help you validate your design before full mass production.
Do you provide material certificates for 316L parts?
Yes, we can provide EN10204 3.1 material test certificates (MTC) for all raw materials upon request, to help you meet your compliance and quality requirements.
Can you help optimize our drawing to reduce production cost?
Yes, our engineering team will review your drawing for DFM (Design for Manufacturability). We can provide suggestions on wall thickness, machining path, tolerance stack-up and non-critical dimension adjustments to help lower your production cost without affecting performance.
