Specially designed of screw and made of alloy steel and with nitrided &
precision processed, so that, there are no dead angle of extruding. Especially,
due to various plastic material character to couple wiht cooling system which
can be melted completely and mixed evenly, unloading quickly, moreover, those
plastic material will not change quality or character, high efficiency, good
The two stage synchronous take-up unit and couple with cooling water
circulating system which can be cooled and held temp for plastic sheet,
Stretching properly, conveying smoothly and not to bread off, little of waste,
increasing production rate.
Standardized of components & parts, easy & simple of replacing.
