High efficiency blown film machine screw barrel

Introduction:
The screw is made of high-quality alloy steel, which has been precisely processed, tempered and nitrided, and has the best hardness and corrosion resistance. The specially designed screw is equipped with a forced conveying bushing, with a reasonable structure, stable performance, good plasticization, high output, low energy consumption, and clear stratification. It is an ideal choice for producing high-strength, aging-resistant, drip-free, light-transmitting, heat-insulating and other multifunctional films.
