Construction & Heavy Equipment

TMC combines two different materials
to create parts with high durability and wear resistance.

BUSH

Guide Pin Bushing

  • PEM Bushing

    [Guide Pin Bushing]

  • PEM Bushing

    [Bushing for Molds]

  • The upper part of the mold set is moved up and down or left and right along the guide pin.
    : Designed for smooth operation of the top plate of the mold inserted inside the guide pin
  • Fixed to the fixed side plate, it plays the role of a bearing and decreases the resistance when moving along the guide pin.
    It is used in various forms according to the mold structure.
