Pressure Forming Process | PPT | Forming Process | ENGINEERING STUDY MATERIALS Pressure Forming Process: Pressure forming is an advanced plastic manufacturing process whereby a plastic sheet is molded to a complex and detailed shape utilizing a single-sided mold to create the formed shape using vacuum & pressure on opposing sides of the sheet. Pressure forming is an enhancement to the vacuum forming process. With traditional vacuum forming, the parts are being formed by creating a vacuum on the mold side of the sheet. Since atmospheric pressure is 14.7 pounds per square inch (PSI) this is the theoretical maximum forming pressure available with vacuum forming. With pressure forming, a pressure box is added to the non-mold side of the sheet. The hot plastic sheet creates the seal between the pressure box and the mold. Air pressure up to 60 PSI is then added to the non-mold side of the sheet in addition to pulling the vacuum on the mold side. This can effectively increase the forming pressure 3 to 4 times what is available with vacuum forming. Universal Plastics’ sales and engineering teams can provide you with guidance on selecting the right plastic manufacturing process for your needs. If pressure forming is right for you, we will convert your design to a 3D model for manufacturing. Advantages: This added forming pressure enables creating thermoformed parts with much sharper detail. The appearance on the mold side of a pressure formed part can look virtually identical to an injection molded part but at a much lower tooling cost than injection molding or other alternative processes such as RIM molding and structural foam molding. Pressure formed plastic parts are also a good alternative to sheet metal, fiber glass or wood. Pressure forming is especially advantageous when using a female mold. The mold can even be textured just like an injection mold so the texture is formed directly into the finished part.
