What are the criteria for the classification of plastic materials at injection molding and extrusion?
The new plastic materials, manufacturers have set by type of good applicability, according to the model can be used, but not to say that the plastic extrusion grade no injection molding, injection molding grade plastic extrusion processing can not, some engineers to use the material properties, will use the technological method for solving extrusion or injection molding grade between the influence.
In comparison, the lower melt flow rate is applicable to the extrusion grade, and the higher is applicable to the injection molding grade. As to what is low and what is high, there is a difference between the different plastic varieties.
Plastic material is injection molding or extrusion grade, there is no standard, but there is an applicable reference value, that is, the material "melt flow rate" value.
