  Twin-screw extrusion technology leads the new trend of TPE foam particle production   With the advancement of materials science, thermoplastic elastomer (TPE) foam particles are becoming the new darling of the plastics industry because of their excellent properties and wide range of applications. TPE foamed particles are not only used in the automotive, construction, medical and consumer products sectors, but also become an important part of the sustainable development strategy due to their environmentally friendly and recyclable properties.   TPE foam particles are widely used in many industries because of their light weight, high elasticity and good cushioning properties. In the automotive industry, TPE foamed particles can be used to manufacture lightweight components such as seals and shock pads, resulting in increased fuel efficiency and ride comfort. In the construction sector, TPE foamed particles can be used to produce thermal insulation materials and sound insulation panels to improve the energy efficiency and residential comfort of buildings. In addition, TPE foam particles are also widely used in medical devices and consumer products, such as the handles of medical devices and children's toys, providing good touch and safety.   In the process of producing TPE foam particles, the heating temperature is a key factor. Depending on the characteristics of the TPE material and the desired foaming effect, the heating temperature is usually controlled between 130-170 ° C. Too high a temperature may cause excessive foaming on the surface of the material, affecting the quality of the product, while too low a temperature may lead to insufficient foaming.   Twin-screw extruder is the core equipment for producing TPE foam particles. It is composed of a transmission device, a feeding device, a barrel and a screw. The working principle of the twin-screw extruder is to mix, melt and transport TPE material in the barrel through the rotation of two parallel screws. Compared with single-screw extruders, twin-screw extruders have higher mixing efficiency and better heat transfer performance, enabling more uniform control of the temperature and pressure of the material, resulting in high-quality TPE foam particle production.   In twin-screw extruder, the material flow velocity field and the material transfer mode are the key factors that affect the product quality. The screw geometry of the tightly meshed cross-rotating extruder can obtain a high degree of forward displacement transport characteristics, while the flow velocity distribution of the material in the twin-screw extruder is quite complex, requiring precise control to ensure the uniformity of the foaming effect.   With the continuous progress of technology, the application of twin-screw extruders in the production of TPE foam particles will be more extensive, and new vitality will be injected into the development of the plastics industry.

  Recently, the plastic extruder industry has undergone an important technological innovation, with new extrusion technologies not only improving production efficiency but also making significant progress in environmental protection. As an important equipment in the plastic processing industry, the technological progress of plastic extruders is of great significance to the development of the entire industry.   Raw materials and their processing：Plastic extruders mainly use common plastic raw materials such as polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC). These raw materials usually require pre-treatment, such as drying and mixing, before entering the extruder to ensure the stability of their physical and chemical properties. During the extrusion process, these plastic particles will be fed into the feeding port of the extruder and transported to the heating zone through the rotation of the screw.   The new generation of plastic extruders adopts a more precise heating system, which can be precisely controlled according to the characteristics of different raw materials. Taking polyethylene as an example, its heating temperature is usually between 180 ℃ and 220 ℃. Within this temperature range, polyethylene particles will gradually melt, forming a viscous melt. This process mainly involves physical changes and no chemical reactions occur. However, for polyvinyl chloride, the heating temperature needs to be controlled between 160 ℃ and 190 ℃ to prevent its decomposition and the production of harmful gases.   During the heating process, the screw of the extruder not only serves to transport the raw materials, but also through its shearing and mixing effects, evenly mixes the melted plastic, eliminates bubbles and impurities, and ensures the quality of the final product.   This technological innovation mainly focuses on the application of twin-screw extruders. Compared to traditional single screw extruders, twin-screw extruders have higher mixing efficiency and stronger processing capabilities. Its screw structure design is more complex, enabling precise control of plastic raw materials. The advantage of twin-screw extruders is that they can handle more complex plastic formulations and meet the processing needs of various plastic raw materials.   The new extruder also has significant performance in energy saving. By adopting an efficient heating system and optimized screw design, energy consumption is significantly reduced. In addition, companies have introduced more environmental measures during the extrusion process, such as using renewable materials and reducing waste emissions. This not only helps to reduce production costs, but also responds to the increasingly strict environmental requirements worldwide.   Conclusion: The innovation of plastic extruder technology not only improves production efficiency and product quality, but also greatly reduces its impact on the environment. With the continuous enhancement of global environmental awareness, the investment in technology research and innovation in the plastic extruder industry will continue to lead the development direction of the plastic processing industry. We look forward to the future plastic extruder technology achieving more intelligent, efficient, and environmentally friendly production, bringing more value to the industry and society.

    Twin screw extruder is one of the more popular types of modern plastics processing equipment. Compared with the traditional single-screw extruder, the twin-screw extruder has the following advantages: the twin-screw extruder can process raw materials into molded products faster during the extrusion process.
