FAQ

Q1: What stainless steel grades can you use?

A: Standard material is 304 stainless steel. 316 stainless steel is available for corrosion-resistant working environments.

Q2: Can you customize thread size and shaft dimensions?

A: Yes. Shaft length, step diameters, thread standard and all dimensions can be customized per your drawings.

Q3: What drawing formats do you accept for quotation?

A: STEP, IGES, STL, DWG, DXF and PDF. 3D STEP file is preferred for accurate quotation.

Q4: What is your MOQ?

A: Flexible MOQ. We accept 1 piece for prototype, small batch and mass production.

Q5: What tolerance can you achieve for the shaft concentricity?

A: Normally ±0.005~0.02mm. We can meet strict concentricity and tolerance requirements as marked on your drawing.

Q6: How long is the prototype lead time?

A: Normally 3–7 working days for prototype. Bulk lead time depends on quantity and machining complexity.
