Main considerations for SMC auto parts compression molding machine
1. Equipment tonnage When selecting the molding process of SMC/GRP composite products, the tonnage of the hydraulic press (molding press) can be selected according to the unit pressure that the product bears the least. For eccentric products or products with large depth dimensions where the moldi...Read more -
Problems and solutions that easily occur in the SMC molding process
The problems that are likely to occur in the SMC molding process are: blistering and internal bulging on the surface of the product; warpage and deformation of the product; cracks in the product after a period of time, and partial fiber exposure of the product. The reasons for the related phenome...Read more -

Development of basalt fiber
Speaking of basalt fiber production technology, I have to talk about Paul Dhe from France. He was the first person to have the idea of extruding fibers from basalt. He applied for a U.S. patent in 1923. Around 1960, the United States and the former Soviet Union both began to study the use of ba...Read more -
Compression Process of 1000 Tons Carbon Fiber Composite Forming Hydraulic Press
Carbon fibers are mainly a special fiber composed of carbon elements, which varies depending on the kind of carbon, generally 90% or more. Carbon fibers have characteristics of general carbon materials such as high temperature resistance, friction, conductive, thermal conductivity, corrosion resi...Read more -

Composite hydraulic press scope application
The composite series hydraulic press products are suitable for the molding of thermosetting and thermoplastic products in the automotive, aerospace, home appliances, military and other industries. There are many types of composite materials. At present, the composite materials widely used in hydr...Read more -
The temperature influence for SMC molding products
The temperature change during the molding process of FRP is more complicated. Because plastic is a poor conductor of heat, the temperature difference between the center and the edge of the material is large at the beginning of molding, which will cause the curing and cross-linking reaction to not...Read more -
