What is Injection Molding?

Injection molding is a type of plastic molding used in the creation of solid plastic items that are more complex in shape than pipes or flat sheets. Toys, plastic silverware, and car parts are examples of products best made with injection molding. Liquid plastic is forced into a metal mold under intense pressure. The resulting plastic piece is eventually cooled and removed from the mold, ready to be cleaned and finished.

What Our Clients Get

Often times, plastic molding facilities will outsource some of the work that goes into an injection molding project, like requiring clients to supply their own CAD specs for example. Making changes to molds or even getting ahold of a live, English-speaking engineer can be tough. We’re different at Valencia Plastics. Here, we offer all-in-one services and a friendly, knowledgeable team who can always answer your questions.

  • So we finally went through and assembled 5000 parts manufactured for us by VP, and we had very low percentage of nonconforming parts. I am very happy with the work VP did. They are an excellent supplier for plastic parts and I highly recommend them.
    Joshua S. Carlsbad, CA
  • Valencia Plastics was a very professional company in helping in deciding in what direction to go with my invention. First they developed the 2D and 3D drawings that I required to make my prototype and then the actually helped me in finding a 3d printing company that can actually make the prototype for us... I would recommend this company to someone that needs a plastic or blow molded product.
