Description

The screw and the cylinder of SJ-PP type automatic or manual PP plastic strapping hand making machine adopt excellent-quality alloy steel through nitrogenization treatment and has the advantages of long life for use. Good abrasion resistant and high output if extruding. With the advantages of automatic temperature control, economical power consumption. high output and easy uses PE powder which is mainly I&II grade recycling material as its main raw material.During the process of producing the granules needn&#**9;t to be dried or mixed and directly use mineral powder instead of expensive master batch to produce automatic strapping band.Which can improve the quality of the products and reduce the production cost of the cllocated printing devece to a great extent.
