Purchasing a plastic extrusion production line is a very important equipment investment that requires comprehensive consideration of various factors and the needs of enterprise development. In this blog, we, as a professional plastic extrusion line supplier, will delve into the key points of purchasing plastic extrusion equipment to eliminate any doubts you may have about purchasing plastic extrusion production lines. From understanding the characteristics and advantages of this manufacturing and processing technology, to how to choose materials, evaluate costs, and service life, we have provided you with the following professional suggestions for reference.
Navigating Material Selection for Plastic Extrusion
According to the different usage characteristics of different types of plastics, plastics are usually divided into three types: general plastics, engineering plastics, and special plastics.
Universal plastic: generally refers to plastics with high production capacity, wide applications, good formability, and affordable prices. There are five types of general plastics: PE, PP, PVC, PS
Engineering plastics: generally refers to plastics that can withstand certain external forces, have good mechanical properties, high and low temperature resistance, good dimensional stability, and can be used as engineering structures, such as PC, PA, POM, PET, PPS, PEEK
Special plastics: encompass a diverse range of materials engineered to fulfill unique and demanding requirements in specialized applications. These plastics exhibit exceptional properties tailored to specific functions, such as high temperature resistance, flame retardancy, chemical inertness, or biocompatibility. Examples of special plastics include fluoropolymers like PTFE and FEP, which offer outstanding chemical resistance and non-stick properties.
What Are the Advantages of Plastic Extrusion?
(1) Continuous production can produce pipes, plates, bars, profiles, films, cables, and single wires of any length as needed.
(2) High production efficiency: The single machine output of an extruder is relatively high. For example, a 65mm diameter extruder can produce PVC film with an annual output of over 450t.
(3) This processing method has a wide range of applications and is widely used in the processing of rubber, plastics, and fibers, especially in plastic products. Almost the vast majority of thermoplastic plastics and some thermosetting plastics can be processed using this method. In addition to directly molding products, extrusion methods can also be used for mixing, plasticizing, granulation, coloring, and billet forming. If an extruder is combined with a rolling machine, it can produce rolled films; Cooperating with a press machine, it can produce various pressed molded parts; Collaborating with blow molding machines, it can produce hollow products. In the production process of rubber products, the extrusion method is used to manufacture tread, inner tube, rubber tube, and various complex cross-sectional shaped products, as well as semi-finished products such as hollow, solid, and encapsulated rubber. It can also be used for continuous mixing, plasticizing, and granulation of filter rubber and raw rubber. In the process of producing resin in petrochemical plants, an extruder can be used to remove moisture from the resin, and various grades of resin additives and modifiers can be mixed using an extruder to complete the resin granulation process.
(4) One machine can use multiple extruders, capable of processing multiple materials and products. As long as different screws and machine heads are replaced according to the material performance characteristics and the shape and size of the product, different products can be produced.
(5) Compared to injection molding and rolling, extrusion equipment is simpler, easier to manufacture, has lower equipment costs, and is more convenient to install and debug. The equipment occupies a relatively small area, and the requirements for the factory and supporting facilities are relatively simple.
How Much Does Plastic Extrusion Cost?
Plastic extrusion equipment has strong customization capabilities, usually requiring specific equipment technical configurations to be customized based on the customer's product size, material characteristics, production requirements, and other factors.
