They are easily adjusted in coil diameter and pitch. We possess a whole set of CNC manufacturing and testing equipments ranging from wire tensile strength tester, shot peening machine, deburring machine, magnetic poweder flaw detector, to compression tester. This enables us meet all customers'demands. Most of our Φ0.1mm to Φ0.8mm compression spring machines are equipped with length detector and automatically selecting instrument. These machines can calcuate CPK automatically. Only with accurate free length can our spring achieve consistent force per customers'request.
