Description

technical field

[0001] The invention relates to a heating screw for a plastic processing machine and a manufacturing method thereof, and belongs to the technical field of heating screw for a plastic processing machine. Background technique

[0002] In the prior art, plastic granulators, injection molding machines, blow molding machines, and extruders all adopt the design of installing electric furnace wire heating ring heating on the machine tube of the screw rod, that is, external heating. This design has some problems in use: the outer circle of the electric furnace wire heating ring and part of the outer circle of the machine tube are exposed, so that part of the heat energy is dissipated in the space, resulting in waste of heat energy; because this design can only be heated and plasticized through the inner hole wall of the machine tube Plastic, so that the plastic near the inner hole wall of the machine tube is plasticized faster and more fully, while the plastic farthe...
