Performance and features:

1. The screw and barrel are both made of high-quality alloy steel of 38 chromium molybdenum aluminum, which has undergone nitriding treatment. The screw is also treated with hard alloy spraying, resulting in high hardness and good wear and corrosion resistance.
2. The screw has a large aspect ratio and is equipped with a spiral core cylindrical die head, which ensures good plasticization, high strength, and good film uniformity of the product.
3. The screw, traction, and winding all adopt stepless frequency conversion and torque speed regulation, and each section of heating adopts automatic temperature control, which is energy-saving and environmentally friendly.
4. This machine produces supermarket bags, vest bags, with good brightness, hard hand feel, and strong tensile strength.
