Blown Film Extrusion Line
-
1970 is the year of our first machine for Blown FilmExtrusion Line, until now, we are always seeking for better know-how, offeringthe complete Blown Film Line combined mature technology and well devisedconcepts.
-
Today, we are focusing on new film applications of Naturepolymer – Starch, PLA, plastic biodegradable polyester film blown, which is ahot topic in modern society for green issue. We also keep our leading advantagein stationery PP file film extrusion, taking almost 70% market share of Asian inthe PP file protector film extrusion machine of stationery industry.
-
To create a cost - effective production system, maximizeprofitability and flexibility, we combine with computer control system by PLC ,the touch screen control panel centralizes all the machine's components frommaterial feeding to film winding, which continually monitors and manages allset points and parameters, and easily re-program to match future requirement,and assure optimum output quality and efficiency. The finish film is flat andsmooth with accurate specification.
Characteristic of The Machine
-
Screw and barrel are designed to adopt the specialcompounding function to melt at high speed and homogeneous, also get greateroutput.
-
Spiral flow channel die is designed to stabilize meltflow. Optional rotating device is chosen and helpful to eliminate gauge band onthe web.
-
Air/ water rings are alum-alloyed special design forproviding excellent and stable cooling. The combination of air and watercooling rings for water output and air blow stably working together, whichresults in excellent film transparency, film surface is evenly and glossy.
-
Take-off unit allows adjustment to the proper height andprovides effective film cooling.
-
A variety of winders including manual, 2 bobbin type, 4bobbin type, back to back winder with computerized tension control for highquality film.
-
Computerized speed control system of take-off and windingunits will provide precise winding quality, won' t cause tensile or broken offilm.
