Application of spiral die head

Spiral die-heads are widely used in plastic extrusion, rubber processing, metal drawing and other fields. It is usually designed to ensure uniform heating, mixing and extrusion of materials during the production process. Here are some common uses of spiral die-heads:

Plastic processing: In the plastic extrusion process, the spiral die-head can help the plastic to mix evenly during the heating process and ensure a smooth surface of the finished product. This is very important for the production of plastic products such as films, pipes, profiles, etc.

Rubber production: Spiral die-heads are used in rubber extrusion molding to ensure the uniformity and accuracy of rubber during the production process, especially in the production of tires, sealing strips and other products.

Food industry: In the production process of some foods, spiral die-heads can be used to control mixing and molding to ensure the quality and shape of food.

Metal processing: Spiral die-heads are also used in the processing of some metal materials, such as drawing copper wire, aluminum wire, etc., which can effectively control the metal molding process.

Composites: In the manufacture of composite materials, spiral die-heads can help mix different components and maintain the consistency and strength of materials.

The working principle of the spiral die is usually to generate a spiral driving force through the spiral design, pushing the material to flow along the die head and gradually forming the desired shape. This design helps to reduce the possible stratification of the material during the flow process and ensure the quality of the final product.
