Extrusion Production Line - Introduction to Several Types of Extruders

Parallel twin screw extruder

Product introduction: The barrel and screw adopt a "building block" structure, with a fully engaged screw and strong self-cleaning performance. It can be combined and arranged according to the process requirements of users for various materials, with interchangeability, wide adaptability, and good mixing, plasticization, and exhaust effects. The material of the machine barrel can be selected as 38CrMoALA and nitrided according to the processing material; Alternatively, alloy liners can be used for good wear resistance. The machine barrel adopts a cast aluminum heater and is cooled by water. Using a DC motor or AC motor variable frequency governor.

SJ series new high-efficiency single screw extruder

The two-stage overall design enhances the plasticization function, ensuring high-speed and high-performance extrusion. Special barrier and BM type comprehensive mixing design ensure the mixing effect of materials. High shear and low melting plasticization temperature ensure high-performance extrusion of materials.

SJZ series conical twin screw plastic extruder

The SJZ series conical twin screw plastic extruder is an efficient mixing and extrusion equipment. It has the advantages of low shear rate, difficulty in material decomposition, uniform plasticization and mixing, high yield, excellent quality, good self-cleaning, wide applicability, and long service life. PVC powder is directly formed with good results. Adopting automatic temperature control, vacuum exhaust, screw core oil cooling, and barrel cooling, there are two types: air cooling or oil cooling. The main motor and feeding motor can adopt AC variable frequency speed regulation system or DC speed regulation system respectively. This machine has a wide range of uses, equipped with corresponding screws, heads, and auxiliary machines, which can directly extrude various thermoplastic thermosetting plastics and modified plastics from powder state into plastic products such as tube, plate, rod, film, hollow, and special-shaped cross-section profiles. The SJSZ series conical twin screw extruder, equipped with corresponding screws and auxiliary machines, can directly extrude various thermoplastic plastics, especially hard polyvinyl chloride powder, into pipes, plates, sheets, films, and shaped materials. It can also complete the modification and powder granulation process of various plastics. This machine adopts a direct current motor, thyristor stepless speed regulation, equipped with overload protection and fault alarm, screw core oil circulation constant temperature, barrel oil cooling, and equipped with a vacuum exhaust pipe device and a quantitative feeding device.
