  • Quality control:

We strictly implement the quality management system, including the following steps:
Raw material inspection: Strictly inspect the purchased rubber materials to ensure that the material quality meets the requirements.
Molding inspection: Perform appearance inspection and size inspection on the molded sealing strip to ensure that the molding quality meets the standards.
Durability test: Conduct durability test to simulate long-term use to ensure that the sealing strip has good durability.
Anti-aging test: Conduct anti-aging test to test the performance of the sealing strip under high temperature, ultraviolet rays and other environments to ensure its stability and durability.

  • Functional features:

Sealing and waterproof: The bus sealing strip can effectively prevent rain, dust and foreign objects from entering the car, keeping the car dry and clean.
Sound insulation and shock absorption: The elastic material of the sealing strip can absorb and isolate external noise and vibration, and improve the riding comfort of passengers.
Environmentally friendly and durable: Made of environmentally friendly materials, it has good durability and long-term stability, and is not easy to age and deform.

  • Installation method:

Built-in installation: The sealing strip is directly embedded in the sealing groove of the bus body, door, and window to ensure a tight fit and sealing effect.

Fitting installation: Some sealing strips are designed with self-adhesive glue on the back, which can be directly attached to the body or door surface, which is simple and quick.

  • Notes:

Installation location: Choose a suitable installation location according to the bus model and the door and window structure to ensure that the sealing strip can be fully attached and seal.

Cleaning and maintenance: The installation location needs to be cleaned before installation to ensure that the surface is clean and free of oil and dust. Regular cleaning and maintenance can extend the service life of the sealing strip.

Regular inspection: Regularly check whether the sealing strip is damaged, aged or deformed. If there is a problem, replace it in time to ensure the sealing effect.

  • Frequently Asked Questions (FAQ):

1. Is the sealing strip easily affected by high temperature?

- Automobile molded sealing strips are usually made of high temperature resistant rubber materials, which can maintain good elasticity and sealing performance in high temperature environments.

2. Is the sealing strip easily affected by grease and chemicals?

- Good quality sealing strips have certain oil resistance and chemical resistance, and can resist the erosion of common automobile grease and chemicals.

3. Is the sealing strip easily damaged?

- The sealing strip has good wear resistance and aging resistance, but it may age or be damaged in special environments or after long-term use, and needs to be inspected and replaced regularly.

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.
