Building SMC Mould
We are also specizlized in making BMC/SMC mould,have more than 5 years experience.
We have a smart and professional team,which have abundant experience on mould analysis and mould designing,more than 5 years of experience in BMC/SMC mould design. Also using advanced software and high precision tooling machine to make good shape and good quality compression mould /SMC mould.
1) The mould is heated.
2) Piece of the selected plastic is placed into the mould and warms up.
3) The hydraulic press begins to move down when the plastic has reached the correct temperature.
4) As the upper and lower mould meet, the plastic is compressed into the shape of the mould.
Basic characteristics SMC and BMC are thermoset, that means crosslinking materials where the crosslinking is irreversible. This is the base for the unique technical performance of these materials class and the mold.
The materials consist of the following components:
SMC/BMC/DMC Composite:Resin, Shrink compensation, Fillers, Reinforcement, Additives, Curing system; Moulding of SMCand BMC: Moulding is made in heated steel tools at temperatures between 125°C and 170°C.
Mold categories:
1. Compression Moulding
Layers of SMC or preformed pellets of BMC are placed into the heated mold. Through closing the tool the material fills the cavity and polymerizes. After complete cure the parts are released hot.
2. Transfer Moulding
Preformed SMC or BMC is placed in the injection valve of the heated mold and is injected into the cavity after closing the mould. The material fills the cavities of the mold . After complete cure the parts are released hot.
Transfer moulding is used for multi cavity tools of thick parts with high requirements for strength.
3. Injection Moulding
BMC or injection SMC are placed in the stuffer which feeds the injection unit. For these thermosets non return valves are used. The Composit is injected into the closed hot mold, fills the cavities andpolymerizes. After complete cure the p |
