In the daily production of twin-screw extruders, the gearbox needs to perform necessary maintenance work.

One of the symbols of the development of internal kneaders is the high-speed, high-pressure, and high-efficiency machines. Generally, low-speed internal kneaders are referred to as those with a rotor speed of 20rpm, those with a speed of 30-40rpm are referred to as medium speed internal kneaders, and those above 60rpm are referred to as high-speed internal kneaders.

Plastic extruder is a common plastic mechanical equipment. In the daily operation of the extruder, various faults are inevitable, which affect the normal production of the extruder. Below, we will analyze the faults of the extruder in detail.

Bridging occurs when materials interlock or bond together, forming an arch above the container outlet. There are many factors that cause the "bridging" phenomenon: particle size, shape, specific gravity, humidity, static electricity, the cohesive strength and internal friction of a single particle will all have an impact on the "bridging" phenomenon. When this happens, the arched structure holds the rest of the contents in the feeder in place, preventing the remaining material from being discharged.

The plastic extruder pull bar granulation production line can be used for granulation of masterbatch, PE/PP+CaC03 materials, or recycling granulation of LDPE, HDPE, PP, ABS, PET and other raw materials.

Plastic granulator machines have revolutionized the way we handle plastic materials. They enable us to transform plastic waste and raw materials into manageable granules, reducing waste and contributing to sustainability. This guide aims to provide a comprehensive understanding of plastic granulators, their advantages, and their crucial role in promoting efficiency and sustainability.

Plastic compounding refers to a process in which various additives and ingredients are mixed or compounded with plastic resins to create a customized material with specific properties. This process allows manufacturers to enhance or modify the characteristics of plastic materials to suit particular applications.

Double-stage extruder （SP Series） and twin-screw extruder (TSE Series) are the main product series of Kairong Group & Haisi Extrusion. There are big differences between these two models.

Plastic pelletizing systems are vital in the plastics industry, enabling the efficient production of uniform pellets or granules from various plastic materials, which can be used in a wide range of applications. The choice of system depends on the material, throughput, and quality requirements of the specific production process.

Plastic compounding equipment is a common plastic processing equipment, which is used to mix different plastic raw materials together and make them into plastic granules or plastic sheets through processes such as heating and extrusion. The importance of plastic compounding equipment lies in its ability to provide an efficient plastic compounding process to ensure the quality and performance of plastic products.
