SMC materials was first applied in Federal Germany and UK in 1960-s, and then was greatly developed in U. S. A in 1970-s and in Japan in 1980-s respectively. Because it is endowed with favorable electrical property, mechanical performance, good high-temperature proof and chemical anti-erosion as well as being anti-erosion, it is adoptable for various processes, that is to say, it can meet performance requirements for different products, and it is widely used in all areas.

Die Molding temperature: 150C
Duration: 60-70s/mm
Pressure: 10-20Mpa
Practical process should be measured according to the products and mold structure, if the products are thick, the temperature should be lower. Most molding temperatures are 135C-145C. Higher molding pressure is required for complicated products.
