A 70 extruder production line is a complete industrial system designed for the continuous manufacturing of plastic, rubber, or composite products through the extrusion process. It is widely used in industries such as packaging, construction, automotive, electrical insulation, and consumer goods. The “70” usually refers to the screw diameter of the extruder, which is 70 mm. This size is suitable for medium-output production and offers a good balance between processing capacity, material compatibility, and operational stability.The production line typically includes several key parts: a feeding system, a main extruder, a heating and cooling system, a die head, a calibration or forming section, a traction unit, a cutting or winding unit, and an intelligent control panel. Raw materials such as plastic pellets, powder, or additives are first fed into the hopper. Inside the barrel, the rotating screw conveys, compresses, melts, and homogenizes the material through controlled heat and mechanical shear. The molten material is then pushed through the die, which determines the final shape of the product.A 70 extruder production line can be configured for a variety of products depending on the die and downstream equipment. It may be used to produce pipes, profiles, sheets, cables, granules, or film-like materials. Because of its moderate screw diameter, the line is often chosen for operations that need consistent quality and flexible production without requiring extremely large space or energy consumption. It is suitable for both standard production and custom manufacturing needs.One of the major advantages of this production line is its high level of automation. Modern control systems allow operators to monitor temperature, pressure, motor speed, and output rate in real time. This improves product consistency, reduces manual labor, and helps minimize material waste. Many systems also feature frequency control, energy-saving motors, and automatic alarms for overheating, overload, or material blockage.The 70 extruder production line is also valued for its durability and ease of maintenance. The screw and barrel are usually made from wear-resistant alloy steel, ensuring long service life even under continuous operation. The modular structure of the line makes it easier to clean, replace parts, and adjust settings for different materials or product specifications.In terms of performance, this type of line offers stable extrusion, uniform melting, and reliable dimensional accuracy. It is capable of processing a wide range of thermoplastic materials, including PVC, PE, PP, ABS, and other engineered compounds. Depending on the material and configuration, the output can be adjusted to meet different production requirements.Overall, a 70 extruder production line is an efficient, versatile, and dependable solution for modern manufacturing. It combines precision, automation, and flexibility, making it an important asset for businesses seeking stable output and high-quality finished products.
