  SMC Compression Mold process compression molding is the most common choice for high-volume composite parts, usually related to SMC (sheet molding composite) and BMC (bulk molding composite) materials.

  Compression molding takes place in equipment called "compression molding presses", which are usually hydraulically powered. You can find it in our compression molding equipment, with tonnage ranging from 150 to 4,000 tons, a super large bed, which can produce super large parts, multiple robots, and machining cells for secondary processing. Put the preheated SMC into the lower part of the mold. Then lower the upper plate and apply pressure up to 2000 psi to the mold. The cycle time is 1-5 minutes, depending on the part size and thickness. Continuous application of heat and pressure will cause the SMC to diffuse and fill each part of the SMC mold correctly. Therefore, SMC compression molding can be used to produce complex and detailed parts with high precision.

  SMC molds require heating rather than cooling systems. The temperature of the mold is usually between 130 and 160. When designing the mold, it is very important to maintain the temperature control of the mold. Commonly used heating systems are steam, oil, and electric heating rods. SMC products with Class A surfaces are usually vacuum-assisted. SMC molds must have sensors and vacuum systems to measure mold temperature and pressure. The SMC Mold produced must guarantee high quality, long life, and economy.
