Processing of Flexible Rubber Magnetic Strips

Rubber magnetic strips are flexible magnetic materials that can be cut to any size. They are used in window screens, door curtains, sensors, refrigerators, motor vibrating feeders, and more. Today, we'll introduce their manufacturing process.

1. Ingredients

Mix magnetic powder, rubber, and other additives (such as fillers, adhesives, etc.) in proportion, most of which use strontium ferrite magnetic powder.

2. Compounding

The mixture is thoroughly stirred and homogenized using compounding equipment. The purpose of compounding is to uniformly disperse various raw materials throughout the rubber, forming a consistent magnetic rubber compound.

3. Extrusion or Calendering

The mixed magnetic rubber compound is processed through an extruder or calender to form the desired shape, such as strips or flat sheets.

4. Vulcanization

Rubber is cured through vulcanization under controlled temperature and pressure. This critical step in rubber processing enhances the material's strength and elasticity.

5. Cooling and Curing

After vulcanization, the rubber strips must be cooled, typically through water cooling or air cooling, to reduce their temperature to room temperature.

6. Cutting or Forming

Cut the cooled magnetic rubber strips according to specifications to achieve the required length and shape.

7. Magnetization and Inspection

Magnetize flexible rubber strips after cutting or forming to impart the required magnetic properties.

8. Packaging and Storage

Magnetic rubber strips that pass inspection are packaged and stored in the warehouse.

The above outlines the overall manufacturing process. Each step requires strict control of process parameters and quality standards to ensure the performance and quality of the final product.
