  • 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
  • Polystyrene
    insulation and energy absorption. Copolymers of polystyrene formulated into EPS-type foamable resins provide improved beat tolerance, solvent resistant, or cushioning. Expandable PS foams are produced in a two-stage process. The resin particles are first expanded to the density required
  • Extrusion Process Creates Dangerous Static: NRD Ionizers Safely Eliminate Problem
    Expanded polystyrene (EPS) is manufactured in a process where it is extruded in a sheet and then "formed " or expanded, using gas that is injected into the material during extrusion. The gas that is released after the EPS is extruded is flammable and can ignite if a static discharge takes place
  • Case History: New Feeders Boost EPS Production and Efficiency at Bandex
    Bandex S.A., located in San Luis, Argentina, manufactures disposable containers and plates from expanded polystyrene (EPS). The production line extrudes and thermoforms virgin polystyrene, recycled polystyrene, talc, and masterbatch color pellets. Bandex is the market leader in EPS packaging
  • 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
  • CNC Routers Increase Productivity in the Plastics and Foam Industry
    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 into molds, then heated
  • Application Articles: CNC Router Drops Production Time for Foam Samples from Five days to Two
    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 polyethylene (EPE), expanded
  • Medical Device Link .
    dunnage or cushioning can be designed to prevent leakage. Such packaging includes expanded polystyrene foam, open- or closed-cell foams, inflatable pillows, and corrugate. Returnable packaging and dunnage can also be created if a closed-loop system can be defined. Saf-T-Pak Inc. (Edmonton, SK
  • 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
