- High temperature, the viscosity decreases, making more favorable flow, pressure flow generator is also reduced. However, the temperature increase of about 200C, the resin flow of liquid resin is about 1% volume expansion, such as the density of molecules in a corresponding volume decreased 1%. That means that, when the temperature is higher line liquid plastic greater shrinkage, internal stress increases, more and more warped. It is important mechanical properties of products also declined due to tight material.
