I plant the production of dual-mode first prize is to be blown unit from both sides of Article Mitoya screw die Barrel and a combination of two Masterbatch configuration, blowing a variety of colorvest bag ( Procurement bags), do not need color printing can be achieved, and has a colorful uniform lines, reasonable structure, advanced technology, rolling formation, and high production.

1, the host machine from a drive, two-sided article Mitoya Barrel and a die component, through both sides of Article Mitoya Barrel Feeding a extrusion die at the same time, coiling traction device that can effectively improve colorfilm production.2, screw, cylinder used 38CrMoAl, after nitrogen treatment and precision machining formed, high hardness, resistance and high corrosion resistance, and durability.3, die hard chromium plating, and its structure mandral spiral type, melt extrusion material uniform,thin-film-blowing finish well, air-cooled structure of the maze-type devices, the air flow evenly.4, Take-up device using the pressure of rolling friction or rolling center, regulating the use of torquemotor, rolling formation, for convenient volume.
