What is the tolerance range that GREFEE can achieve?

Tolerance changes according to manufacturing technologies and material types. Generally tolerance is affected by the following factors:

  • Product size
  • Geometric construction
  • Characteristic quantity, type and size
  • Processing material
  • Surface requirement
  • Processing equipment
  • Processing technology

Once your order is confirmed, we’ll provide you feasibility report as soon as possible, which will point out any tolerance range we cannot achieve, and the problems exist in parts. It will greatly save cost and time if you help note key dimensions when place order. Following are design tips for tolerance.

  • tolerance range for CNC metal machining, tolerance range for CNC plastic machining.
  • tolerance range for injection molding.
