Structure and Principle
Plastic machine screws are usually composed of threaded parts, chrome plated or surface coated parts, cooling water channels, and heating resistance wires. The threaded part of the screw is responsible for conveying plastic particles from the hopper to the injection machine barrel, and melting the plastic under high temperature and pressure, while being controlled by the heating and pressure inside the injection machine barrel. Chromium plating or surface coating can improve the wear and corrosion resistance of screws and extend their service life. The cooling water channel and heating resistance wire are used to control the temperature of the screw, ensuring the correct processing temperature of the plastic material.
Main features
High wear resistance: Plastic machine screws are usually made of high-strength alloy steel materials, which have undergone special treatment or surface coating, and have good wear resistance. They can adapt to working environments with long-term high-speed operation.
High precision: The threaded part of the screw is precision machined to accurately control the compression and melting process of plastic particles, ensuring the dimensional accuracy and surface quality of the formed product.
Good stability: The structural design of the screw is reasonable, the processing technology is exquisite, and it can maintain stable performance under long-term high load working conditions, reducing equipment failures and downtime.
Strong Customizability: Based on different injection molding processes and plastic material characteristics, plastic machine screws with different diameters, pitches, and structural forms can be customized to meet the personalized needs of customers.
Application area
Plastic machine screws are widely used in various injection molding equipment, including plastic injection molding machines, rubber injection molding machines, silicone injection molding machines, etc. It plays a crucial role in the plastic product processing industry, such as automotive parts, household appliances, daily necessities, industrial equipment, and other fields.
