PAQ / FAQ

Q1: What material do you use for this locating block?

A: Standard material is 6061 aluminum alloy. 7075 aluminum alloy can be chosen when higher strength is required.

Q2: What benefits does hard anodizing bring?

A: Hard anodizing greatly improves surface hardness, wear resistance and corrosion resistance, suitable for repeated positioning and friction scenarios.

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?

A: Normally ±0.005~0.02mm. We can meet strict tolerance requirements according to 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.
