1. Plastics processing industry:
In plastic extruders, parallel twin screws and cylinders play a key role in melting, mixing and conveying plastic materials. Screws made of high-quality alloy steel can withstand high temperature, high pressure and corrosive substances in plastics, ensuring the stability and efficiency of the extrusion process.

2. Rubber industry:
Rubber extruders also need parallel twin screws and cylinders to mix and convey rubber materials. The wear resistance of alloy steel screws can extend the service life of equipment and improve production efficiency.

3. Chemical industry:
In the chemical industry, parallel twin screws and cylinders are often used to convey and mix corrosive chemicals. High-quality alloy steel can resist the erosion of these chemicals and ensure the long-term stable operation of equipment.

4. Food processing industry:
In some food processing equipment, such as screw pumps and extruders, parallel twin screws and cylinders are used to convey and process food materials. The hygiene and wear resistance of alloy steel screws make them an ideal choice for the food processing industry.

5. Oil and gas industry:
In the process of oil and gas extraction, processing and transportation, equipment that can withstand high pressure, high temperature and corrosive environment is needed. Parallel twin screws and cylinders play a key role in these equipment, and high-quality alloy steel is its ideal material.

6. Machinery manufacturing industry:
In the machinery manufacturing industry, parallel twin screws and cylinders are often used in transmission and power systems. These parts made of alloy steel can withstand large loads and impacts, ensuring the stability and durability of the machinery.
