The smc mold needs to be heated, not cooled. The temperature of the mold is usually between 140 and 160. In mold design, maintaining mold temperature is very important. The mold is easier to fill, the product is not easily deformed, and the surface is better. Commonly used heating systems are steam, oil, high-pressure water or electricity. When the temperature of the mold design system pays special attention to make the temperature of the mold on the entire surface consistent, a uniform temperature can reduce deformation, improve the size of stability, and the uniformity of the product surface.
LFT, long fiber reinforced thermoplastic material, English is Long Fiber reinforced Thermoplastics, is compared with ordinary fiber reinforced thermoplastic material, usually, the fiber length of fiber reinforced thermoplastic material is less than 1 mm, while LFT, The length of the fiber is generally greater than 2 mm. The current processing technology has been able to keep the fiber length in the LFT above 5 mm.
