The twin-screw extruder is developed on the basis of the single-screw extruder. Due to its good feeding performance, mixing and plasticizing performance, exhaust performance, and extrusion stability, it has been widely used in the production of extruded products.

The difference between twin screw extruder and single screw extruder is mainly reflected in the following two aspects.

The desktop film blowing machine is mainly composed of a single screw extruder, film blowing die head, film blowing frame, blower and so on
The whole machine adopts the integrated structure, the single screw extrusion host and the film blowing unit share the same frame and set in one
frame, compact structure.

In order to promote the standardization of equipment with high quality, Guangzhou Putong Experimental Analytical Instrument Co., Ltd. organized and held the desktop small precision extrusion film blowing machine type acceptance meeting on June 6, the company's senior executives, functional departments and the relevant responsible person of the research department attended the meeting.
