Explanation.

Chaplets:

Chaplets are used in the casting process of the production system to support a sand core inside a sand mold cavity. The design of the chaplets and the manner in which they are placed in the mold cavity surface allows each chaplet to sustain a force and chaplets are located beneath the core to support it before pouring, and chaplets are placed above the core to resist the buoyancy force during pouring.

  • Chaplets are used to support the core due to buoyancy force act by the molten metal casting process.
  • No use of chaplets in other manufacturing processes like welding, forging, extrusion, etc

Important Points

  • Chaplets are an integral part of casting to ensure that the material of the chaplet must be the same as casting.
