Sealing Strip Production Process

Raw Material Procurement
The company rigorously selects high-quality suppliers to procure rubber, plastics, and various additives that meet national and international standards, ensuring material quality.
Raw Material Inspection
Advanced equipment and a professional team are employed to comprehensively inspect raw materials, including their physical and chemical properties, ensuring they meet production requirements. Only materials that pass inspection proceed to the production phase.
Compounding and Mixing
Accurate compounding and mixing are conducted according to product formulation ratios. High-efficiency mixing machines ensure thorough blending of raw materials to achieve uniform consistency. The mixed materials undergo a maturation period to ensure material stability.
Extrusion Molding
Maturation-treated mixed materials enter the extrusion molding process. Different extruders and molds are used based on product shapes and specifications. Stringent control of parameters such as temperature, pressure, and speed ensures products meet design requirements in terms of size and appearance.
Vulcanization and Cooling
Products after extrusion molding undergo vulcanization to enhance their physical properties and durability. Vulcanization occurs under high temperature and pressure conditions using vulcanization machines to ensure uniform curing. Post-vulcanization, products undergo cooling to further stabilize performance.
Cutting and Processing
Cooled products enter the cutting and processing stage. Precision cutting and further processing such as edge trimming and hole punching are performed according to specific product requirements. During processing, strict control of dimensions and accuracy ensures products meet design specifications.
Surface Treatment
Processed products undergo surface treatment as required, such as spraying, impregnation, or bonding. Surface treatment enhances product appearance and improves properties such as corrosion resistance, waterproofing, and wear resistance.
Final Inspection
All finished products undergo rigorous final inspection. The company utilizes advanced testing equipment and a professional quality inspection team to comprehensively test dimensions, physical properties, chemical properties, etc. Only products that pass inspection are packaged and ready for shipment; non-conforming products are reworked or scrapped.
Packaging and Storage
Inspected and approved products proceed to packaging. Suitable packaging materials and methods are selected based on product characteristics and customer requirements to ensure products remain undamaged during transportation and storage. After packaging, products are stored in the warehouse awaiting shipment.
