SMC and BMC Hot Press
Hot press is a production method that provides, producing composite parts from different molding compound formulations under pressure. It is preferred in high quantity productions because of high investment costs. The following products are under this product range: Polipol 347 for production of park equipment, boxes, recycle bins; Polipol 3417-V for production of high surface quality vehicle parts, composite boxes and cases; Polipol 382 for production of high thermal resistant and chemical resistant composite parts. Polipol 3418 all maleic resin is used in applications where both high surface quality and thermal resistance are needed.
SMC-BMC production methods are one of the fastest production methods for producing composite parts.

SMC-BMC Paste Production
① Prepare the mixture of Polipol resin, peroxide, thickening agent MgO, filler, thermoplastic additives, pigment paste and internal release agent.
② Transfer resin mixture to the carrier film. Chop glassfiber and sprinkle it onto the resin mixture.
③ Apply second layer of resin mixture to second carrier film.
④ Apply second carrier film on top.
⑤ Press the compound between two carrier films and roll up for maturation for at least two days at 20-23°C.
Note: Temperature has an influence on maturation speed. Maturation will be slower at lower temperatures. For higher mechanical properties, different glassfiber alternatives can be used.

.
SMC Hot Press Application
① Release the plastic films from the matured compound.
② Place the compound into the hot mold at temperatures between 130-170°C .
③ Ideal molding pressure should be around 150-170 kg/cm2. Molding should take 1minute for every 1mm of material thickness.
④ After molding, demold the product and trim edges.
