SMC mould door step

SMC  tooling,BMC tooling are usually designed with hydraulic cylinders with flow diverters for the ejection side.Many of the SMC tooling,BMC toolings are polished to diamond finish and textured prior to chrome plating.

SMC tooling and BMC tooling normally heated by oil and steam.The temperature directly affects the products quality and production efficiency of products,the tooling with a uniform temperature will fill easier and produce parts with less warpage,improved dimensionnal stability and uniform surface appearance.Achieveing a uniform tooling temperature is dependent on the method of SMC toolings,BMC toolings heating.

A tooling that is heated by steam or oil will have a uniform temperature because the heat source maintains a constant temperature.Electrically heatedSMC toolings,BMC  toolings are more difficult to maintain at a uniform temperature because the cartridge heaters are contantly cycling on and off.when they are on,they generate a great deal of heat at the source but this heat must be dispersed throughout the tooling in a way that produces a uniform toolings temperature.

Heating the SMC  tooling,BMC tooling by steam is faster than by oil,temperature is uniform,but not easy to control,oil heating,the temperature is more uniform than steam,and stability,but pollute the environments.However,oil as a heat sourse is only about half as efficient as steam.Therefor,when using oil to heat a tooling,it is necessary to set the oil temperature higher than the desired tooling temperature.Whatever your SMC or BMC tooling needs we have the design & manufacture capabilities to fulfill them.

There have different requirement for SMC products accuracy in different applications.we provide products with good serviceability according to customers‘ request.If we emphasis on product accuracy would increase the cost of production cost,manufacturing products and quality control will be more difficult.In generally,it depends on design requirements and assembly requirements of customers.The following respects roughtly introduced the related factors effect the precision of SMC products.

1)SMC material shrinkage

It is the  important basis to calculate the moulding  product’s size，also  will affcet product accuracy and deformation.

2)SMC paoducts structure

During design the SMC product,need pay attention to below point:

①products shape

②product thickness

③Draft

④choosing Material

⑤SMC mould design and manufacture
