Hot runer size options include hot runner manifold plate size options and runner sizes options.
In order to withstand the injection pressure, opening the flow path, heating system installation, the manifold plate should have a sufficient size, and in order to minimize power and heat loss, the volume of the manifold plate should not be too large. Minimize the quality of the manifold plate, the smaller manifold plate quality, the heating system less power. Also ensure that the surface roughness in a certain range within the flow channel.
Flow characteristics and properties of each material is not the same diameter, the size of the flow channel choices are different. For heat sensitive materials with smaller flow channel dimensions of the flow channel can reduce the capacity of the material, but the shear-sensitive material to be used a larger flow channel to reduce the size of the shearing action. Those requirements can change color in the case of the smaller size of the flow channel can quickly scour the old colors. The design of the mold hot runner melt flow analysis can be used to determine the optimal size of the flow passage,the analysis takes into account the type of materials and processing parameters. This particular application will be able to produce an optimized flow channel dimensions.
