PVC needs to add additives in processing in order to produce various products that meet people's needs, such as soft, hard, transparent, good electrical insulation, foaming, etc. When selecting the variety and dosage of additives, it is necessary to comprehensively consider various factors, such as physical and chemical properties, flowability, and formability, in order to ultimately establish an ideal formula.

Coupling is an important connecting device between the main motor of the extruder and the gearbox. Currently, nylon rod couplings and safety couplings are commonly used on the market. Nylon rod couplings have a simple mechanical structure and low cost, but the torque is not accurate. They rely entirely on the shear force of the torque greater than that of the nylon rod. When the nylon rod is cut off, it needs to be reattached.

The main components of automobile lights are composed of reflectors, lenses, casings, light sources, electronic circuits, and installation accessories. With the development trend of lightweight automobiles, the proportion of plastics in automobiles is getting higher and higher.

With the development of industries such as automobiles, machinery, electronics, and aerospace, the requirements for material properties are becoming increasingly high. Developing high-performance and multifunctional modified nylon (PA) special materials has become a major research and development topic.

Loss-in-weight feeders are used to continuously measure the volume and weight of bulk solid feed materials, such as powders, granules, liquids, flakes and fibers. Haisi Extrusion supply loss-in-weight feeding equipment specially designed for screw extruders.

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.
