Structural Foam Molding
Our Low Pressure Structural Foam Molding & Plastic Injection Molding facilities form the heart of our manufacturing capabilities! Plastic Industries has gas assist structural foam molding machines ranging from 375 ton to 500 ton, with shot capacity up to 150 pounds.
Structural Foam Molding is primarily a low pressure injection molding process. Typically it’s used to process materials like high density polyethylene (HDPE), in a low pressure machine. 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 caused by an inert gas distributed in the plastic material to facilitate the flow. Low Pressure Structural Foam Molding is primary achieved when Nitrogen (or other gases) are added to the injection molding process to create a polymer that is lighter in weight than standard injection molded parts. Also gas assist structural foam molded parts are not only more light weight but more durable than other standard injection molded parts. Low pressure structural foam molded parts have a significant density reduction, sometimes as large as 40%, from its base material. They typically exhibit excellent strength-to-weight ratio, improved thermal and acoustic insulation properties, but suffer from lower tensile strengths.
Other in-house services include design and engineering capabilities, in-house fully equipped tool facility, warehousing and integrated quality control. We can also provide press side packaging, hot stamping and sonic welding.
Make sure to remember our unique location in east Tennessee makes shipping products to the East, North East and Mid West portions of the USA less expensive and faster. Plastic Industries is located off interstate I-75 and is only 30 minutes from I-40.
