There are four general types of wipers:

  • 1.Bone: You can obviously see the metal skeleton.
  • 2.Traditionally no bone: outside the package of rubber, which is a metal spring.

3.No three-segment type: there are three sections, the  support body is plastic, built-in metal spring.

4.A new generation of non-bone three-stage: there are  three sections, the support body is plastic and metal  skeleton, built-in metal spring, is a combination of bone  and bone, generally divided into bone wipers.
