Product Name EXTERNAL GAS MOLDING (EGM) Description EGM works by Injecting gas to form a thin layer of gas between one surface of the plastic and the adjacent mould cavity surface. Using the gas to apply pressure to the plastic whilst cooling, forces it against the opposite mould cavity to improve surface replication and heat transfer. EGM is used primarily for thin-walled applications and was developed to remedy molded surface imperfections. Benefits: • Can eliminate sink marks • Improves dimensional stability • Reduces clamp tonnage / machine size required • Reduces wear on molds • Reduces power consumption • More design freedom Applications: • Flat panels for office equipment • Computer enclosures • Furniture e.g. table-tops • Automotive panels • Domestic appliances e.g. refrigerator tops

Product Name LIQUID COOL Description Liquid Cool is a new, high-pressure, water process which both complements and extends gas assisted moulding. It uses the heat transfer capabilities of water to speed up the cooling of molten plastic. This allows for more efficient and cost-effective manufacturing. The technology essentially flushes water through the moulding during the cooling process. As the heat capacity of water is significantly higher than that of gas, the process allows for the overall cycle time of a product to be reduced. This is a new approach to the use of water that causes little disruption to established injection moulding processes but that meets the demands of customers worldwide. Benefits: • Cooling times reduced significantly • Short pay-back period • No fundamental change in mould process – reduced uncertainty A full range of equipment accessories and consultancy services are also available.

Product Name OPTIFOAM Description Cinpres will be highlighting the benefits of a new process – Optifoam – a retrofit system option for extrusion, using a foaming technique and physical blowing agents. This provides an easy replacement for chemical blowing agents and can deliver significant cost-savings in extruded product. The main advantages of Optifoam include improved melt and product quality, and no screw modifications. The foaming process also enables reductions in material density. The Optifoam system can be mounted on any extrusion line independently from the manufacturer.

Product Name PLASTIC EXPULSION PROCESS (PEP) Description The Plastic Expulsion Process, exclusively licensed through Cinpres, is particularly suited to components with a combination of tick and thin sections. Solid parts of components can be cored-out with this technique. Benefits: • Reduction in the weight of components • Reduction in raw material required • Reduction in cycle times • Improved part quality Applications: • Automotive – dashboards, doors, pillars, tailgates • Consumer electronics – TV and PC surrounds, printers • Home appliances – vacuums, washing machines, dryers

Product Name WATER ASSISTED MOLDING (WAM) Description Water Assisted Molding (WAM) is a further addition to the Cinpres range offering benefits to existing methods of assisted molding. The process can be used effectively to reduce cooling times by up to 50 per cent of that of traditional gas molding, predominantly used for producing thick section tubular parts. Based on the Plastic Expulsion Process (PEP) – patented and licensed by Cinpres Gas Injection – WAM molds hollow or partly hollow components by injecting water into the molten plastic in the mold and gives core-out with a smoother interior surface finish and reduced cycle times. Direct cooling inside the part presents a significant advancement in the market of assisted molding. The thermal conductivity and heat capacity of water is significantly higher than that of gas, allowing a more rapid cooling process and greater productivity to the end user.
