Injection Mold in China: Important Parts That You Need to Know

What are the essential part of an injection molding machine? Hopper – plastic pellets are being fed through the hopper. Barrel – the barrel heats the pallet to liquefy them. Reciprocating Screw – this part is in charge of making the liquefied plastic more fit for molding.

Defects Cause Analysis of BMC products

​It is due to the presence of gas when the BMC substrate is pressurized, which leads to protrusions on the surface of the product.

What is sheet molding compound (SMC)

Although the chemical properties of sheet molding compound (SMC) are similar to those of bulk molding compound (BMC), the manufacturing process is quite different. SMC is made into a sheet shape, so it is easier to be used in various fields, and its mechanical strength is much more prominent than its thermoset family counterparts. SMC usually contains 10-65% fiber-reinforced material, which is composed of strips of chopped glass fibers ranging in length from 1/2 to 2 inches (or 12.7 to 50.8 mm).
