Gas-Assist & High Pressure Structural Foam Molding

• Increased surface finish
• Reduced resin usage
• Vastly Improved Mold Fill-Out
• Virtual elimination of 'sink marks'

Gas-assist lets designers mold thin-walled parts with less clamp tonnage, thereby cutting the cost of tooling and the size of the molding machine. It also is said to be an ideal method for adding hollow sections to an otherwise flat part. Conventional injection molding can't easily produce such a configuration. Other plastic forming processes such as blow or rotational molding have a tough time with it as well.
