What is a mold?

335Views

Molding or molding plastic machining process to form a liquid or soft raw material using a rigid frame called a mold or matrix. This in itself may already use a pattern or the final object of the model.

A mold or plastic mold is a hollow block filled with liquid or soft materials such as plastic, glass, metal, or ceramic raw materials. The liquid in the mold hardens or collects and adopts its shape. A mold is a peer. A very common bi-valve molding process uses two molds, one for each half of the object. Piece-molding uses many different molds, each cnc creating a complex object of a part. This is usually only used for larger and more valuable objects.

The maker of the mold is called a mold-maker. Agents are usually used to make the removal of hardening/setting substances from the mold easier. Typical uses of molded plastics include molding furniture, molding household items, molded cases, and structural materials.

The types of molds include:

  • 1. Blow molding
  • 2. Powder metallurgy + sintering
  • 3. Compression molding
  • 4. Extrusion
  • 5. Injection
  • 6. Laminating reaction injection molding
  • 7. Matrix forming
  • 8. Rotational molding (or rotomolding)
  • 9. Spin casting
  • 10. Transfer molding method
  • 11. Thermoforming Vacuum forming, a simplified version of thermoforming
