What are the design principles of Conical Screw Barrel and its unique advantages in industry applications?

Conical Screw Barrel has a unique design principle and shows significant advantages in many industrial applications.
Its design principle is based on the optimization of material conveying and plasticizing processes. The diameter of the conical screw gradually decreases from the feed end to the discharge end. This gradual structure makes the material transportation process in the barrel more orderly. In the plastic processing industry, such as injection molding, after the raw material enters the barrel from the hopper, the material is gradually pushed forward as the screw rotates. The design of the conical screw can produce gradually increasing compression of the material. At the feed end, the larger screw diameter provides a larger space to facilitate the smooth entry of materials. As the material moves toward the discharge end, the screw diameter decreases and the material is compressed more tightly, which is beneficial to improving the material quality. The plasticizing effect. Because during the compression process, the friction between the material and the screw and barrel increases, and the heat generation increases, which promotes the melting and mixing of the material and makes the plasticization of the plastic more uniform.
In the field of rubber processing, the conical screw barrel also has excellent performance. Rubber materials usually have high viscosity and elasticity, and the structure of the conical screw can better adapt to the processing characteristics of rubber. During the mixing process, it can effectively fully mix rubber with various additives (such as vulcanizing agents, fillers, etc.). Because the conical screw extrudes and shears the rubber more uniformly, it can avoid local overheating or uneven mixing, and improves the quality and efficiency of rubber mixing.
From an energy consumption perspective, the conical screw barrel has certain advantages. Because its special structure enables better plasticization and transportation of materials within a shorter screw length, compared with traditional equal-diameter screw barrels, the screw speed and driving power can be reduced under the same production tasks. Thereby reducing energy consumption. For example, in some large-scale plastic extrusion production lines, the use of conical screw barrels can reduce energy consumption by 10% - 20%.
Our company's conical screw barrel adopts advanced manufacturing technology and high-quality materials, and the geometric shape and size of the screw and barrel are precisely designed to ensure that it can give full play to its unique advantages and improve production efficiency in applications in plastics, rubber and other industries. , reduce energy consumption and improve product quality.
