Q1:

Can you machine pins with extremely small diameters?

A1:

Yes, our precision CNC lathes can machine stepped pins with diameters as small as 1mm with high repeatability.

Q2:

Do you provide Passivation or Electropolishing?

A2:

Absolutely. All our stainless steel pins undergo ultrasonic cleaning and passivation to ensure maximum rust resistance.

Q3:

Can I get a quote with only a physical sample?

A3:

Yes, our engineering team can perform reverse engineering on your sample to create a digital CAD drawing for production.
