The production process and manufacturing process of EPDM strips generally include the following steps:
1. Material preparation: Prepare the required EPDM raw materials and auxiliary materials according to the product requirements. This includes EPDM, fillers, plasticizers, stabilizers, etc.
2. Formula modulation: According to the formula ratio of the product, mix EPDM rubber with other additives in a certain proportion. This is usually done in a rubber mixer or mixer to ensure that the materials are evenly mixed.
3. Extrusion molding: Send the mixed EPDM rubber material into the extruder, and extrude the required strip shape through the extrusion head. The extruder heats, pressures and extrudes the compound through an extrusion die to form a continuous bead.
4. Forming and curing: the extruded rubber strips are cut or broken to obtain the required length of rubber strips. Then, put the adhesive strip into an oven or other heating equipment for curing to obtain a certain hardness and elasticity.
5. Surface treatment: According to needs, the surface of the rubber strip may be treated, such as coating with special coating or glue, to increase its weather resistance, chemical corrosion resistance and adhesion.
6. Inspection and quality control: Inspection and quality control of the produced EPDM strips, including appearance inspection, size measurement, physical performance test, etc., to ensure compliance with product requirements and quality standards.
7. Packaging and storage: Pack the EPDM strips that meet the quality requirements, such as rolls or strips, and then mark and store them, ready for shipment or supply to the market.
It should be noted that the specific production process and manufacturing process may vary depending on the manufacturer and product, but the above steps generally cover the common production process of EPDM strips. In actual production, it is also necessary to carry out corresponding control and adjustment according to product requirements and quality management system to ensure the production of high-quality products that meet customer needs.
