What is volumetric dosing units for the plastic granular,
Plastic granular materials usually refer to organic polymers that have a softening or melting range after being heated, and flow under the action of external force during softening. They are solid, semi-solid, and sometimes liquid organic polymers at room temperature. Broadly speaking, any polymer compound that can be used as a raw material for the processing of plastic products is called a resin.

In the process of processing and mixing plastic products, resin materials are usually used, and the difference in the finished products prepared by different amounts of resin materials is overcome.
