Composition
 

SMC and BMC, as well as derivatives which include: TMC (Thick Moulding Compound), HPC (High Performance Compound) CIC (Continuous Impregnation Compounds) and AMC (Advanced Moulding Compounds) are all fibre reinforced composite materials which primarily consist of a thermosetting resin matrix (normally UP -unsaturated polyester), reinforcement (normally glassfibre) and inorganic filler.

Additional ingredients such as low-profile additives, cure initiators, thickeners, process additives and mould release agents are used to enhance the processability of the material and the end-performance of the part. Typically less than 30 percent of an SMC/ BMC recipe is a crude oil derivative either as unsaturated polyester resin or thermoplastic additives. The remainder is inorganic filler and reinforcing glass fibres, chopped into lengths: 25 - 50mm for SMC and 6 -12mm for BMC.

LFT-D long fiber reinforced thermoplastic directly inline molding

1. The micro-opening technology of proportional servo is adopted, and the minimum height of stable mold opening can reach 0.1mm.
2. Adopting the unique fast and slow flexible switching technology, the slider fast and slow conversion realizes the no-flow breakpoint switching, and the safety of the slider operation is greatly improved.
3. The key parts are sealed by radial sealing, and the oil leakage of the press is effectively controlled.
4. The thermoplastic composite production line has a complete set of supply capabilities for material processing, molding processes, molds and automated full-line bus control integration.
