Material: Double-layer silica-titanium gel, stainless steel wire, glass fiber blended, high-performance synthetic material.
In the soft connection of stainless steel and the forming process of thermoplastic plastics with high temperature and soft material, because of the change in volume, strong internal stress, large residual stress in the plastic parts, strong molecular orientation and so on, the shortening rate is larger than that of thermosetting plastic, and the shortening rate is wide and the direction is distinct. The shortening after forming, annealing or humidification is also generally greater than that of thermosetting plastics.
The melting material and the cavity surface touch the outer layer and immediately cool down to form a low density solid shell. Because of the poor thermal conductivity of plastics, the inner layer of the plastics is slowly cooled to form a shortened high density solid layer. So the wall thickness, slow cooling, high density layer thickness is shortened. In addition, there are no embedded parts and inserts planning, and the number directly affects the direction of the flow of material, the dispersion of density and the reduction of the resistance, so the characteristics of the plastic parts have a great influence on the shortening of the size and the direction.
