This dramatically decreases the fill pressure required to mold a part. There are tooling advantages to the Low Pressure Structural Foam process. Low Pressure Structural Foam Molding | Todd & Associates, Inc The material does not fill the mold completely. The chemical reaction forms gas bubbles inside the now-melted resin. These machines can be used for Structural Foam, Structural Web, Gas Assist, Solid Molding, or combinations of these technologies depending on the application. As a result, the plastics we make with foam molding are ideal for outdoor environments or other environments where fluctuations in temperature and humidity are common. Structural foam molding is on the receiving end of growing attention from big players including Ford, BMW, Porsche and VW, for its ability to reduce part weight by up to 20%, and in some cases offering cost savings of up to 15%. Single Nozzle Structural Foam molding utilizes a chemical blowing agent to create the cellular structure within the wall section. The center section of the nominal wall is where the cell structure / foam occurs. Other advantages include less energy usage due to the low-pressure process and cost savings and sustainability from using less resin and less-expensive aluminum tooling. Structural foam plastic molding is an injection molding process that utilizes a foaming agent that mixes with the base resin in the polymer melt before being injected into the mold. The process is able to use quite a few different types of base polymer resins to produce finished structural foam products. A. Because of these specific requirements it is beneficial to identify if structural foam will be utilized to produce a part early on in the design process. The process creates a singular large and complex part that normally requires many components to complete. Structural foam molding results in plastics that have remarkably high dimensional stability. It also means proudly manufacturing our products in America, and making them available to the global marketplace. The density of material within a part depends heavily on its local temperature during curing. Instead of using high pressures to force the molten polymer to fill up the cavity of the mold, structural foam molding relies on the foaming action . eFunda: Introduction to Structural Foam Molding Structural Foam Molding. Engineers must consider the design criteria early in the process, rather than switching molding techniques. Introducing the Structural Foam Molding Design Guide Choosing the right tool material is dependent on the types of resin selected and the accumulated volumes expected for the tool life.
