Temperature range: under 300 degrees, the temperature can be used for more than 6 hours, 250 degrees can be used for a long time, resistance to instantaneous high temperature 600 degrees, and still maintain good material performance at low temperature of -70.
Material: Double-layer silica-titanium gel, stainless steel wire, glass fiber blended, high-performance synthetic material.
In the process of soft connection of fan, high temperature resistant and soft material type thermoplastic plastic forming process, because of the change in volume, strong internal stress, large residual stress in the plastic parts, strong molecular orientation, and so on, the reduction rate is larger, the shortening rate is wide and the direction is obvious in comparison with the thermosetting plastic. Other shortening after forming, annealing, or humidifying treatments are also generally larger than those 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.
Order requirements: made according to the size of the drawings.
