Why can conical screw barrel improve material mixing and plasticizing effects?

In plastic processing and other related industries, the mixing and plasticizing effects of materials are crucial. The emergence of conical screw barrel has brought new breakthroughs in improving the mixing and plasticizing effects of materials.
First of all, the unique structural design is the basis for the advantages of conical screw barrels. Unlike traditional equal-diameter screw barrels, the screw of conical screw barrels is conical, and the diameter gradually decreases from the feed port to the discharge port. This design makes the gap between the screw and the barrel constantly change during the material conveying process, thereby generating different shear forces and pressures. At the feed port, a larger gap is conducive to the smooth entry of the material and reduces the risk of blockage; at the discharge port, a smaller gap can increase the shear force and improve the plasticization degree of the material.
Secondly, conical screw barrels can achieve better material mixing effects. Due to the conical structure of the screw, the flow speed and direction of the material in the barrel are constantly changing. This complex flow pattern allows materials of different properties to be fully mixed and evenly distributed. At the same time, the screw's rotational motion and conical structure work together to produce a strong stirring effect, further promoting the mixing of materials. Whether adding masterbatch, fillers or other additives, the conical screw barrel can ensure that they are fully integrated with the base material to obtain high-quality mixed materials.
Furthermore, efficient plasticizing ability is another outstanding feature of the conical screw barrel. As the material advances in the barrel, the shear force between the screw and the barrel gradually increases, and the pressure on the material also continues to increase. The effect of this high shear force and high pressure makes it easier for the material's molecular chain to be opened, thereby accelerating the plasticizing process. In addition, the heating system of the conical screw barrel is usually more uniform and efficient, and can provide suitable temperature conditions for the plasticization of the material. Under the right temperature and pressure, the material can reach a good plasticizing state faster, improving the quality and performance of the product.
From the perspective of practical application, the conical screw barrel also has many advantages. For example, it can adapt to the processing needs of different types of materials, whether it is thermoplastics, rubber or other polymer materials, and can achieve good results. At the same time, the structure of the conical screw barrel is relatively compact, takes up less space, and is easy to install and maintain. In the production process, it can improve production efficiency, reduce energy consumption, and bring significant economic benefits to the enterprise.
