point groups Industry Knowledge Expansion

The term "screw and barrel" refers to the components of an injection molding machine or extruder that are responsible for melting and conveying the plastic material. The screw is a long, helical component that rotates inside the barrel, which is a cylindrical housing. The screw and barrel work together to heat and melt the plastic material, and to apply pressure to the molten material as it is extruded through a die to form a desired shape. The term "point group" does not have a specific meaning in the context of screw and barrel design.
