n THERMOSETS A thermoset composite compound is based on unsaturated polyester or vinyl ester resins, fillers and fibre reinforcement. Catalysts, stabilizers, mould release agents, thickeners, pigments and other functional additives are utilised to enhance the properties of the thermoset material, designed to offer superior mechanical properties, excellent electrical and fire protecting characteristics, as well as “Class A” surface appearance and low density characteristics. Its colour can be adjusted to customer needs nevertheless to achieve perfect aesthetic look P.I.M.C technology to be applied.
n COMPRESSION TECHNOLOGY Compression moulding is the transformation technique which is most commonly used for SMC and BMC moulding. This technology is an ideal choice also when large-scale products need to be manufactured. The press tool is a two-sided, hardened or chrome-plated manufacturing tool. Heating of the mould can be provided by steam, oil or electricity. Special shapes and undercuts are formed by hydraulically moved inserts (sliders). At IBV Hungária Kft. we use hydraulically operated press machines with a vertical structure (down: fixed machine table; top: moving side), capable of exerting a compressive force from 200 to 2000 tons
At IBV Hungaria Kft the most common appearances of thermoset material are SMC (Sheet Moulding Compound) and BMC (Bulk Moulding Compound)
n SMC APPEARANCE
A ready to mould glass-fibre reinforced polyester material primarily used in compression moulding.
The material is available in rolls or paper boxes. Both sides are protected with foil (film) that prevents from evaporation of styrene, which is first removed by using a customized cutting machine and then cut to proper size.
