Laboratory Small Single Screw Extruder Film Blowing Machine


Product introduce

This machine is the main equipment of the film blowing machine, and its function is to plasticize and extrude polymer. The screw and barrel are both made of 38CrMoAl alloy steel, and the surface is treated with processes such as nitriding and ultra precision honing. This machine is equipped with 3 zones for heating, and 2 zones for heating the mold head and mold mouth, with a total of 5 zones for heating. 

The extruder screw is divided into three sections: feeding section, melting section, and homogenizing section. 

At the inlet of the feeding section, the heating temperature is set low to prevent the raw material from sticking and blocking the material outlet. In addition, the resin in the feeding section is continuously compressed, and the air will be discharged from the feeding port upside down. Although the feeding port is not heated, it will transfer heat through the machine barrel. Therefore, the temperature of the feeding port can be set to around 50-90℃.

In the melting section, the viscous flow temperature is reached before melting. For crystalline resins, the viscous flow temperature is equal to the melting point temperature. Then, by continuously compressing and increasing the melting layer, it is necessary to continuously increase the temperature in order to make the length of resin molecular chains unequal, so that polymers with different thermal motion energies can melt successively.
