  • Quality control:

Quality control of electrical sealing strips usually includes the following aspects:
Raw material inspection: Strictly inspect the purchased materials to ensure that the materials meet the quality standards.
Production process control: Strictly implement the production process to ensure that each link meets the quality requirements.
Finished product inspection: Perform appearance inspection and dimension measurement on the finished product to ensure that the product quality meets the standards.
Performance testing: Perform performance tests such as high and low temperature resistance, aging resistance, and chemical corrosion resistance to ensure that the product has stable performance in various environments.

  • Applicable scenarios:

Electrical sealing strips are suitable for various electrical equipment, such as household appliances, industrial equipment, and communication equipment. It is widely used in projects such as the sealing of the outer shell and the sealing of the connection parts of electrical equipment to protect the interior of the equipment from dust, water vapor, and other pollution.

  • Installation method:

The installation method of electrical sealing strips is simple and flexible:
1. Clean the installation surface: Ensure that the installation surface is clean, dry, and free of oil and dust.
2. Measurement and cutting: Measure and cut the sealing strip according to actual needs to ensure the appropriate length.
3. Paste or clamp installation: Paste or clamp the sealing strip on the installation surface to ensure a tight fit and avoid gaps.

  • Notes:

1. During installation, ensure that the sealing strip fits the installation surface tightly to avoid gaps to ensure a good sealing effect.

2. The length of the sealing strip should match the length of the installation surface to avoid being too long or too short to cause poor sealing effect.

3. Check the adhesion of the sealing strip regularly. If it is found to be loose or aging, it should be replaced in time to maintain a good sealing effect.

  • FAQ:

1. Is the sealing strip waterproof?

- Yes, electrical sealing strips usually have good waterproof properties and can effectively prevent moisture from penetrating into the interior of electrical equipment.

2. Is the sealing strip resistant to high temperatures?

- The temperature resistance range of the sealing strip is usually between -40°C and +120°C, which can meet the use requirements of most electrical equipment.

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.
