Sheet molding compound machine , SMC Sheet Molding Compounds
Product,smc molding machine
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.
Company composite molding equipment performance characteristics
- Nominal force: up to 5000 tons
- Countertop: Maximum 5000mm
- Slider stroke: up to 4500mm
- The slider has a maximum fast return speed: 800mm/S
- Slider minimum mold opening speed: 0.1mm/S
- Pressure holding accuracy: 0.8MPa/hour per hour (no pressure
compensation)
- Touch screen plus PLC control system, bus control system
- The four-corner leveling system meets the high-precision
requirements for large-area thin-walled parts, and the leveling
accuracy is ±0.05m.
- The hydraulic system uses a piston accumulator, which is 40-60%
lower than that of a conventional press.
- Complete press mechanical locking safety system and electronic
control interlock system.
Company composite molding equipment performance characteristics
LFT-D long fiber reinforced thermoplastic directly inline molding
- The micro-opening technology of proportional servo is adopted, and
the minimum height of stable mold opening can reach 0.1mm.
- 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.
- The key parts are sealed by radial sealing, and the oil leakage of
the press is effectively controlled.
- 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.
