Car windshield seal

Car windshield seals are rubber or plastic seals installed around the car windshield, designed to prevent moisture, dust and noise from entering the car from the edge of the windshield. It seals and protects the windshield while improving vehicle ride comfort.

specification

EPDM rubber: has good weather resistance

high and low temperature resistance and elasticity

and is often used in automobile windshield sealing strips.

PVC plastic: soft and weather-resistant

suitable for sealing windshields of some light vehicles.

  • Features:

Sealing and waterproof: The sealing strip can fit tightly to the joint of the windshield and the car body to prevent rain and car wash water from penetrating into the car.

Dustproof and soundproof: Effectively prevent dust, noise and odor from entering the car through the gap of the windshield, improving riding comfort.

Weather-resistant and durable: It has good weather resistance and aging resistance, and can maintain elasticity and sealing effect for a long time.

  • Installation method:

Fitting installation: The sealing strip is designed to match the joint of the windshield and is directly installed around the windshield.

Clamping installation: Some sealing strips are designed with a clamping structure, which is fixed and installed by clamping the edge of the windshield.

  • Precautions:

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

Cleaning and maintenance: Clean the surface of the sealing strip regularly, and use special rubber maintenance agent or detergent to keep it soft and durable.

Correct installation: During installation, make sure that the sealing strip is completely fitted with the edge of the windshield to avoid gaps that cause water seepage or noise.

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.
