The workflow of a three-layer co extrusion blown film machine

The production process of the three-layer co extrusion blown film machine requires precise control of multiple parameters, such as the temperature, pressure, and speed of the three-layer extrusion head, as well as the stretching speed, smoothness, and thickness uniformity. These parameters are collected, adjusted, and optimized by the automatic control system to ensure excellent quality of the produced membrane materials.

The three-layer co extrusion blown film machine is an efficient plastic film manufacturing equipment, mainly used for producing plastic films with different functions. The three-layer co extrusion blown film machine adopts multi-layer co extrusion technology, which can process multiple plastics of different materials on the same production line, achieve the stacking of different film materials, and thus produce plastic films with special functions.

The workflow of the three-layer co extrusion blown film machine is as follows:

(1) Evenly feed three different plastic particles into the fusion chamber of the extruder.

(2) The extruder uses a hot water circulation system to heat and melt plastic particles, and extrudes the plastic through screws.

(3) The extruded molten material passes through the die head to form a flat film, where the width of the bottom and top films is narrower, and the width of the middle film is wider.

(4) The film is rapidly cooled by a cooling roller to solidify the shape of the plastic.

(5) After cooling, the film is pulled and stretched by a traction device to ensure its flatness and uniformity, so that the three layers of film are densely adhered together.

(6) Send the produced blown film into the discharge device for sorting and cutting.

The three-layer co extrusion blown film machine is an excellent plastic product production equipment. Its working principle is to use a multi-layer extrusion head, which forms a thin film during the stretching and compression process through the hot melt fusion and extrusion pressure of plastic materials. The three-layer co extrusion blown film machine can manufacture multi-layer structured film materials, which can meet the requirements of different colors, transparency, thickness, and physical properties in different layouts. Currently, it is widely used in packaging, construction, agriculture, medical and industrial fields.

Compared with other similar machines, the three-layer co extrusion blown film machine has excellent energy utilization efficiency. It can flexibly adjust temperature and other parameters according to user needs, greatly reducing production costs. This machine has efficient production functions and can produce a large number of thin film rolls in a short period of time. This means that users can increase their production capacity and volume, thereby expanding their careers.
