   feeding and the elastic modulus influence forming distortion, compared with the powder, the smaller elastic modulus of adhesive, feeding the elastic mould of depends on the composition and content of powder binder, temperature can also affect its elasticity and the modulus, polymer can store because of the molecular orientation and volume expansion, resulting in the deformation energy.Often, as the temperature rises, the elastic modulus value is reduced, but because of the different thermal expansion coefficient of powder and binder, can lead to complicated stress changes, therefore, the measured module depends on the stress and the temperature of feed process, this is a substantial difference between the conductivity of powder.Low conductive powder, such as ceramic powder can delay the mould cooling, but easy to accumulate residual stress from forming and cooling.
