  • Use of Infrared Imaging Techniques to Understand and Quantify Expanded Polymer Molding Operations and Part Quality (.pdf)
    The manufacture of expanded polystyrene, polypropylene and similar molded parts (automotive bumpers, protective helmets, etc.) requires precise molding control for its vacuum, steaming and subsequent cooling cycles. These are processes where optimal part quality demands a precise amount of steam...
  • Building safer seats for Indy racers
    they hit the driver. In the past, drivers would sit on a bag filled with expanded polystyrene beads and resin to create an exact imprint of them in their most comfortable driving position. The entire process took at least 20 hr. And every time a car is in an accident or a driver switches cars, a new...
  • The Effect of Process Characteristics on Metal Fill and Defect Formation in Aluminum Lost Foam castings
    The process used to make the foam patterns generally involves two steps. The first step is pre-expansion in which the raw polystyrene beads are expanded to the desired bulk density. The expansion is accomplished by either heating the beads in vacuum, or by applying steam to obtain the desired...
  • Polyolefins
    methods used for expandable polystyrene (EPS). After the beads are expanded (20 to 40 times that of the solid resin) nd conditioned, they are poured into a mold and heated, usually by direct injection of steam. This softens, expands further, nd fuses the particles together, forming a niform, void-free...
  • From Lubricants to Packaging Materials: ARS Scientists Just Say "No" to Petroleum
    . At various points in the process, the beads puff and expand. That happens, for instance, when the beads are put into the cavity of a heated mold, to press them into the desired shape. Expanded beads will eventually touch one another, creating a strong matrix that's much like the bead matrix of polystyrene...
  • CNC Routers Increase Productivity in the Plastics and Foam Industry
    applications such as inside bicycle helmets. The company, which has 250 employees, molds a full range of materials including expanded polystyrene (EPS), expanded polyethylene (EPE), expanded polypropylene (EPP), and copolymers such as GECET, ARCEL, and RMER. These raw materials are injected as beads...
  • Application Articles: CNC Router Drops Production Time for Foam Samples from Five days to Two
    foam products are used in the packaging of items such as electronics equipment and appliances, but they can also be found in other applications such as inside bicycle helmets. The company, which has 250 employees, molds a full range of materials including expanded polystyrene (EPS), expanded...
