Plastic Molding

Unique sourcing problems you may encounter

Plastic molding is the general term for the process of producing plastic products. Plastic molding includes the four main methods: injection molding, blow molding, plastic extrusion, and rotational molding.

  • * Overwhelmingly large number of factories and the number of un-reliable quotes
  • * Getting a different color for your product
  • * Factories use recycled materials

Plastic Injection Molding
Plastic Injection Molding This is a process to make both thermosetting plastic and thermoplastic materials. Materials after being fed through a heated barrel is mixed and then forced into a mold cavity. Then the material is allowed to cool and hardens to form the shape of the mold cavity. This method creates many items such as bottle caps, combs, packaging and most other plastic products available today.
Plastic Blow Molding
Plastic Blow Molding Or blow forming, is a process where hollow plastic parts are formed. This is a process used to produce hollow objects from thermoplastic. The process is completed by blowing air into and expanding the hot pre-form against the mold cavity until it cools. Blow molding is used to make such products: surf boards, bellows, fuel tanks, automobile bumpers and ductwork.
Plastic Extrusion
Plastic Rotational Molding This is a high volume manufacturing process where plastic material is melted and formed into a continuous profile. This process produces items such as window frames, tapes, pipes and wire insulation.
Plastic Rotational Molding
Plastic Rotational Molding Another common term is rotomolding, is a process for creating bigger plastic, hollow items. The product is made by continuously rotating the mold cavity and having the bottom touch a puddle of melted material. The melted material will then flow and stick to the walls of the mold. Maintaining even thickness is achieved by continually rowing the part during the cooling phase.
