Injection molding is a manufacturing process for producing parts or products by injecting material into a mold. Injection molding with plastic starts with pellets and/or plastic flakes and melts with temperatures up to 450 degrees.  Then the machine injects the plastic into the mold.  The mold is water cooled, opens, and the part drops out.  Cost of molds can be $600 to $60,000 or more.  The cost of molds can be worked into product or part production cost.

  • Simple to very complex products  single to multi cavity molds
  • Recycled content from 25 – 50%  Depending on size of product

Blow molding is a manufacturing process by which hollow plastic parts are formed.  The blow molding process begins with melting down the plastic and forming it into a parison or preform. The parison is a tube-like piece of plastic with a hole in one end in which compressed air can pass through. The parison is then clamped into a mold and air is pumped into it. The air pressure then pushes the plastic out to match the mold. Once the plastic has cooled and hardened the mold opens up and the part is ejected.
