Bimetallic Screw And Barrel has many unique advantages in plastic processing, mainly reflected in the following aspects:
1. Wear resistance
The bimetallic screw and barrel are composed of two different metals that have been specially treated to significantly improve their wear resistance. The improvement of wear resistance means that the equipment will wear less during long-term use, thereby extending the service life of the equipment. In addition, the improvement of wear resistance also helps to maintain a stable gap between the screw and barrel, ensuring the fluidity and uniformity of plastic raw materials during the extrusion process.
2. Corrosion resistance
During plastic processing, the screw and barrel often come into contact with various corrosive substances, such as additives and pigments in the plastic melt. The bimetal screw and barrel have high corrosion resistance and can effectively resist the erosion of these corrosive substances and keep the surface of the equipment smooth and intact. This not only helps maintain the stability of the extrusion process, but also reduces equipment failure rates and improves production efficiency.
3. High heat resistance
During plastic processing, the screw and barrel need to withstand the impact and friction of high-temperature melt. The bimetal screw and barrel have high heat resistance and can maintain stable performance and shape in high temperature environments. This enables the equipment to operate at higher temperatures, thereby broadening the application range of plastic processing and increasing processing efficiency.
4. Excellent mechanical properties
Bimetallic screws and barrels are typically made of high-strength, high-hardness metals, which give them excellent mechanical properties. During plastic processing, screws and barrels need to withstand greater pressure and torque, and bimetal screws and barrels can easily cope with these challenges and ensure stable operation of the equipment.
5. Good processing adaptability
The material and structural design of the bimetal screw and barrel can be customized to meet specific plastic processing needs. This customized design allows the equipment to better adapt to different types of plastic raw materials and processing conditions, thereby improving product quality and consistency.
6. Extend the service life of equipment
Bimetallic screws and barrels can significantly extend the service life of equipment due to their excellent resistance to wear, corrosion and high heat resistance. This reduces the frequency of equipment replacement and maintenance costs, bringing higher economic benefits to the enterprise.
