Container sealing strip

Container sealing strip is an important component used for closing container doors, designed to prevent goods from being damaged during transportation due to air leakage, water leakage or theft at the door. It is usually made of high-strength rubber or plastic materials, has good elasticity and weather resistance, and can effectively protect the safety of goods.

  • Features:

Sealing and waterproof: The sealing strip can fit tightly into the gap of the container door to prevent rain, seawater or car wash water from penetrating into the container and protect the goods from moisture.

Dustproof and insect-proof: The sealing strip can effectively prevent dust, insects and other debris from entering the container and keep the goods clean.

Anti-theft and anti-tampering: Some sealing strips are designed with a special locking structure to prevent unauthorized personnel from entering the container and ensure the safety of the goods.

  • Installation method:

Self-adhesive installation: The back of the sealing strip is designed with adhesive, which is directly pasted on the container door frame, which is easy and quick to install.

Screw fixed installation: Some sealing strips need to be fixed to the container door frame by screws or clamps, and the installation is more firm and reliable.

  • Precautions:

Cleaning before installation: Make sure the surface of the container door frame is clean and free of oil and dust.

Sealing check: After installation, check whether the sealing strip is completely in line with the door frame to ensure good sealing.

Regular replacement: Regularly check whether the sealing strip is aging, cracking or deformed. If there is any problem, replace it in time to ensure the sealing effect.

  • FAQ:

1. What is the life of the sealing strip?

- The life of the sealing strip varies depending on the material and the environment in which it is used. It is generally about 1 to 3 years and needs to be checked regularly and replaced as needed.

2. Can the sealing strip withstand high and low temperature environments?

- High-quality sealing strips have good high and low temperature resistance and can be used stably in a temperature range of -40°C to +80°C.

3. Is the sealing strip easily damaged?

- Good quality sealing strips have certain wear and corrosion resistance, but you still need to be careful during loading and unloading to avoid damaging the sealing strips.

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.
