Due to poor distribution of pigments or fillers, the color of plastic or pigment discoloration on the surface of plastic parts is uneven. The reasons for uneven color vary depending on the phenomenon presented. The uneven distribution of pigments near the

As a wet premix, BMC materials contain volatile active monomers, so do not remove their packaging prematurely before use. Otherwise, these active monomers will evaporate from the BMC material, leading to a decrease in material fluidity and even performanc

The quality of SMC sheets has a significant impact on the forming process and product quality. Therefore, before pressing, it is necessary to understand the quality of the material, such as the resin paste formula, the thickening curve of the resin paste, the glass fiber content, and the type of glass fiber sizing agent. Single weight, film peel resistance, hardness, and quality uniformity.

We all understand that SMC is a kind of composite material, with a large number of points. In the production of molds have a variety of points need to grasp, grasp is difficult to produce quality molds, the following, and we introduce in detail about the
