FAQ

★What tolerance you can achieve?

It’s best that you provide 2D drawing with tolerances for us to review, we will give you a detail feedback quickly on each critical tolerance. Of course, we will give you our advice from our experience to design proper tolerances, to reduce manufacturing cost at mean time the necessary requirements are achieved.

If you have no idea on tolerance design, there will be some general tolerance guidelines for your reference. It’s depend on different manufacturing process.
