The perfection degree of plastic machinery of injection molding machine directly affects the quality, output and cost of plastic semi-products or products, so it must be able to adapt to changes in temperature and stress of plastic compounding and processing, and the resulting changes in the properties of molten materials, and to adapt to Chemical corrosion and machinery.

First of all, injection molding machine plastic machinery is a general term for various types of machinery and devices used in the plastic processing industry.

With China's accession to the WTO, the plastic machinery industry is receiving more and more attention. But how do we better understand the plastic machinery industry? Take a look at the following materials first.

Certain fluid and solid transportation, separation, crushing, grinding and drying and other general machinery and equipment also occupy an important position in the plastic processing industry, so they are often listed as plastic machinery.

There are many types of plastic machinery. According to the production process of plastic products, plastic machinery can be divided into four categories: plastic compounding machinery, plastic molding machinery, plastic secondary processing machinery and plastic processing auxiliary machinery or devices.

Plastic mixing machinery is used in the manufacture of various forms of plastic mixing ingredients, including kneaders, plasticizers (openers and mixers), pelletizers, screening machines, crushers and grinders.

Plastic molding machinery, also known as plastic primary processing machinery, is used for the molding of plastic semi-products or products, including compression molding machines, injection molding machines, extruders, blow molding machines, calenders, rotational molding machines, foaming machines, etc.

Plastic secondary processing machinery is used for reprocessing and post-processing of plastic semi-products or products, including thermoforming machines, welding machines, heat sealing machines, hot stamping machines, vacuum evaporation machines, flocking machines, printing machines, etc. Metal processing machines are also commonly used for secondary plastic processing.

Auxiliary machines or devices for plastic processing are used to rationalize the plastic machining process, including automatic metering and feeding devices, automatic scrap recycling devices, automatic plastic product removal devices, injection mold quick-change devices, plastic mold coolers, automatic thickness measurement devices, and Raw material transportation and storage equipment. Such auxiliary machinery or devices have become an indispensable part of the automation of modern plastic machining processes.

The degree of perfection of plastic machinery directly affects the quality, output and cost of plastic semi-products or products. Therefore, it must be able to adapt to the changes in temperature and stress of the plastic mixing process, as well as the changes in the properties of molten materials caused by it, and to adapt to chemical chemistry Special conditions such as corrosion and mechanical wear. In recent years, the specialization of plastic grades, the development of engineering plastics, the emergence of composite materials, the development of large-scale, lightweight and thin-walled plastic product technologies require plastic machinery to achieve: complete sets for high-speed production, Labor-saving and automation to improve the production efficiency of products, ensure the minimum precision of product specifications and quality errors, to achieve low energy consumption, small footprint, convenient and safe operation and maintenance.
