COMPRESSION MOULDING

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.

At IBV Hungaria Kft the most common appearances of thermoset material are SMC (Sheet Moulding Compound) and BMC (Bulk Moulding Compound)

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.

POWDER COATING

P.I.M.C. technology can be used if we want to produce a high quality product in one step (without post-painting, varnishing) or the goal is to achieve “CLASS A” surface quality (body elements, sanitary ware, furniture elements, stadium / train public transport vehicle seats). It is based on the P.I.M.C. powder that is sprayed onto the surface of the tool heated up to 140-150 °C prior to the pressing process.

The aesthetic surface made by the P.I.M.C process is better than those ones made with coloured SMC/BMC. Further advantage is that contrary to other post coating processes it is scratch- and chemical-resistant.

COMPRESSION MOLDING

As one of the largest users of glass fiber reinforced polyester (SMC) in Europe, our company processes more than 3,200 tons of raw materials per year. With our fleet of 37 presses (with a closing force of 200 to 2,000 tons), we are capable to manufacture the desired product in a wide range of sizes.

SMC is used in areas where light weight but high strength and resistant components are also required.
