What are the development trends of plastic extruders? – Suzhou Polytime Machinery Co., Ltd.

With the development of society and the increasing human demand, plastic has become an indispensable material in people's life. In recent years, with the wide application of plastic products and the rapid growth of output, the demand for plastic machinery has been increasing and has gradually become one of the fastest-growing industries. According to statistics, more than 60% of plastic products are processed by extrusion, and extrusion has become the main processing method of polymer materials. Therefore, plastic extruderhas been developed rapidly, and has been more and more widely used because of its excellent processing performance.

What is the process flow of plastic extrusion?
Many kinds of plastics can be processed by extrusion molding, and the products are more diverse. There are many differences in the molding process, but the basic process flow is roughly the same.

The common process of feeding and extruding products in the solid-state is to add granular or powdery materials into the hopper of the plastic extruding machine, and the heater gradually increases the temperature of the materials in the barrel. With the transmission of the screw, the materials are transported forward. During the transportation process, the materials rub and shear with the barrel wall, the screw, and multiple materials, resulting in a lot of heat. The temperature will continue to rise, which can make the materials melt continuously. The molten material continues to be continuously and stably transported to the head with a fixed shape. After passing through the head, the material in a fluid state reaches a shape similar to the mouth shape. Under the action of the traction device, the product can move forward continuously and obtain the final product size. Finally, cut off the products by cutting for storage and transportation.

What are the development trends of plastic extruders?
There are five development trends of the plastic pellet extruder.

1. High speed and high yield

The high-speed and high-yield extruder can enable investors to obtain large output and high returns with low investments. But at the same time, the high speed of extruder screw speed also brings a series of difficulties to be overcome, which are urgent problems to be solved in future development.

2. Efficient and multifunctional

The high efficiency of the plastic extruder is mainly reflected in high output, low energy consumption, and low manufacturing cost. In terms of function, screw extruder has not only been used for extrusion and mixing processes of polymer materials, but has also expanded to a variety of fields such as food, feed, electrode, explosive, building materials, packaging, and so on.

3. Large scale and precision

Realizing the large-scale extrusion equipment can reduce the production cost, while precision can improve the gold content of products. For example, multi-layer co-extrusion composite films need precision extrusion. We must strengthen the development and research of melt gear pumps, which is an important means to realize precision extrusion.

4. Modularization and specialization

Modular production can meet the special requirements of different users, shorten the R&D cycle of new products and strive for greater market share; Specialized production can arrange fixed-point production or even global procurement of each system module component of extrusion equipment, which is very beneficial to ensure the whole period quality, reduce costs and accelerate capital turnover.

5. Intellectualization and networking

Modern electronic and computer control technology has been widely used in extruders in developed countries to detect the process parameters of the whole extrusion process online and adopt microcomputer closed-loop control. This is very beneficial to ensure the stability of process conditions and improve the accuracy of products.

In recent years, great progress has been made in the complete set of plastic machinery in China. For example, the plastic extrusion unit has reached a fairly perfect level, the specifications of various pipe units are becoming more and more complete, and the product level and quality are continuously improved. Suzhou Polytime Machinery Co., Ltd. is committed to developing first-class plastic production machinery with quality as its life, science, and technology as its leading and customer satisfaction as its purpose.
