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.

Thermoplastic elastomer is an environmentally friendly low-carbon composite material that possesses the characteristics of rubber (high elasticity, compression permanent deformation, etc.), as well as the processing characteristics of plastic (simple process). In most regions, the abbreviation TPE is commonly used to refer to thermoplastic elastomers. Another theory is that TPE is the general term for thermoplastic elastomers, TPU is thermoplastic polyurethane, TPV vulcanized thermoplastic elastomers, and TPR is generally considered as shoe sole material in China.

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.
