What is Blow Molding?

The blow molding process is used to make plastic hollow parts, such as containers or bottles. The parts are created by extruding a tube of hot plastic, called a parison into an open mold. The parison is extruded into the mold then pinched at the bottom welding it closed. Air is then blown in through the top of the mold to inflate the parison into the shape of the mold. The mold opens and the new part drops out.

The Rinse Hanger

The Rinse Hanger is a complex blow molded part that was designed to easily and conveniently wash out the inside of your wetsuit. We designed and built the mold using ABS plastic because it is a very tough and durable resin with a UV repellant adaptive. This adaptive will help protect the blow molded tank from harmful UV rays for up to 5 years. The Rinse Hanger is an innovative way to wash the inside of your wetsuit after a fun day at the beach.

  • 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.

  • 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. Next step would building the mold, which they recommended for us to go on kickstarter and raise the money required to build the mold.  I would recommend this company to someone that needs a plastic or blow molded product.
