Materials We Can Custom Die Spring

What is a Die Spring?

The mold spring is the spring used for the mold. It is a commonly used elastic element. It produces large elastic deformation after being subjected to the external force. Die springs are generally distinguished by color, and different colors represent different loads. For specific information, please contact KENENG.

Die Spring VS Compression Spring

Springs are generally divided into three types, namely compression springs, tension springs, and torsion springs, which can be used in molds. Die springs are widely used in various molds such as stamping dies, metal die-casting dies, and plastic dies.

  • The difference between mold springs and compression springs lies in the different manufacturing processes.
  • Die springs are made of square wire, and ordinary compression springs are made of round wire.
  • The strength of the mold spring is much stronger than that of ordinary springs, and its anti-fatigue performance is also better than that of ordinary springs.
