SMC mould design follows similar rules as for any other production process with the plastic industry. But before you build a SMC mould, there are certain things need to be considered.The first and most important is shear edge.
Mould shrinkage
There are two shrinkage for SMC mould. Low profile class A part have a shrinkage of -0.05% to 0%.
Temperature system
SMC and BMC need heating channel instead of cooling. The working temperature of the mould is usually at 140 degree to 160 degree. When designing the temperature systme it is important to keep surface temperature within very close parameters. Mould will fill easier and produce parts with less warpage, and uniform surface appearance. The The mould can be heated by steam, or oil, or electricity or even high pressure water.
vacuum system
To achieve a better appearance of part will require vacuum assistance. For more information please contact our techinician
Production SMC mould
Production mould must be of highest quality and capable of making parts consistently and economically. Ningguang Mould will help you to achieve that.
