Murray Hill & New Providence, N.J., U.S. - New high-tech supply and control systems for cryogenic gases from Linde can help plastics manufacturers and designers address a variety of challenges - from small, intricate parts where water cooling is ineffective, to mold filling, all providing production efficiencies.
High-tech, cryogenic gas technology provides rapid cooling using an inert gas, typically liquid carbon dioxide (CO2), or nitrogen (N2), for molding, extruding and foaming applications.
"Precise cooling of injection-molded and gas-assisted injection-molded parts with complex geometries is just one area where our high-tech systems excel. We are also making it easier than ever for polystyrene (PS) extrusion foam manufacturers to capitalize on the pressure advantages of CO2 - while reducing hydrocarbon foaming agents and the emissions and safety issues associated with them," said Jim Stanley, program manager, industrial applications, Linde North America.
Linde is highlighting the PRESUS(TM) family of precision metering, cooling, pressure boosting and control systems at the 2012 National Plastics Exposition (NPE), April 2-5 in Orlando, FL:
1) DSD 500 high-pressure metering system for extrusion foaming
2) High-pressure N2 boosting system for gas assist injection molding
3) Cost-effective, high-pressure system for CO2
4) Spot cooling device for mold hot spots
Precision cooling and pressurizing systems are important for manufacturing a range of engineered plastics parts for automotive, aerospace, electronics, appliances and MIL-spec applications. The N2 or CO2 may cool the polymer product from in- or outside a mold, or just focus on a specific spot. The Linde Plastics Team reviews processing challenges and develops solutions for injection-molders, foamers and extruders, as well as manufacturers and designers of plastics processing equipment.
