Main Features:
It is used for blowing various low density polyethylene (LDPE) and high density polyethylene (HDPE) color striped plastic film (or double-color film), etc. Which are widely used for packing food, fruit, garments, textile, daily necessities and other civil and industrial products. The cylinder and the screw stem of the extruder are made of high-quality 38 chrome-molybdenum aluminum (optional: alloy steel), nitrogen treated in a precision way. Hence it is sound in hardness, durable in corrosion resistance. The specially-designed screw is of sound quality in plasticizing, which helps increase the production capacity. National standard gear box adopts water cooling reducer, hard tooth surface, and oil pump. The main motor adopts frequency control of motor speed to improve the speed regulating stability of main motor and save electricity by 30%. The film width and thickness can be adjusted according to the technological requirements of different materials, and has been fitted with a plug-in plate mechanism for making vest bag. The coiling unit adopts torque motor to keep proper tension and make rolling even and roll-changing easy.
Optional Equipment:
1)Auto loader and Dryer
2)Cast aluminum heater
3)Air shafts
5)Double-station rewinder
6)Up and down traction unit
7) Alloy steel screw
9)High-speed manual net changer
