Flash treatment in the production process of SMC and BMC molds

In the production process of SMC and BMC mold products, there is a problem that is very important, but it is also easy to handle, that is, flash processing.

Since SMC is a sheet molding compound, a mixed polymer resin, the raw materials are full of glass fibers, minerals, and fillers. The BMC material is a mixture of thermosetting plastic resins in the form of pellets. Due to its short fibers, the fluidity is slightly better than that of SMC. One of the advantages of this material over metal is that it can be customized according to the needs of processing and end customers.

In the production process of SMC and BMC products, the way the raw materials are laid is also very important. The paving material needs to adjust the cutting method, size, weight, etc. of the raw material according to the structure of the product, considering the fluidity of the raw material, and the welding position. Improper spreading of materials can cause nicks, cracks and other problems in the product.

All SMC or BMC products have a flash cleaning process. If it is a high-quality mold, the flash will be very thin, and the cleaning process is very simple. The flash cleaning process can be automated or manually operated by machines.
