Machine Introduction
This Rotary Die Film Blowing Machine is commonly used type in the blown film industry. This is the most economical type which Youjia has rich manufacturing experiences for many years. Most of its final applications are widely used in our daily life which from people’s livelihood to the rising industry of biodegradable. Despite there are lots of advantages in other types of film blowing machine, monolayer blown film extrusion machine is still a great choice for use of many applications.
Compared with the multilayer blown film extrusion machine, the monolayer blown film extrusion machine still has many advantages.
1. The price is lower: the single screw extruder is compact and cheap. Twin-screw extruders are more than twice as expensive as single-screw extruders. Some are higher and the actual prices vary depending on the manufacturer and model specifications.
2. The formula is simple, the single screw extruder's process and secret recipe are relatively simple, while the twin screw extruder's process and secret recipe are more complicated.
3. Easier maintenance: In terms of maintenance, a single screw is easier than a twin screw, because the structure of a single screw is very simple, which is conducive to maintenance.
