The following will explain in detail the materials and welding heat sealing technology of the car seat back inflatable airbag:
1. Detailed explanation of the materials of the inflatable airbags in the car seat back
Polyester fiber: Polyester fiber is one of the commonly used materials in the production of inflatable airbags. It has good strength, wear resistance and chemical resistance, and can effectively protect personnel and equipment from external impact. The use of this material ensures the durability and safety of the airbag.
Nylon cloth: Nylon cloth is another commonly used raw material for inflatable airbags. It has high strength, wear resistance and tear resistance, and is particularly suitable for making high-pressure airbags. The use of nylon cloth ensures that the airbag can still maintain its structural integrity when subjected to high pressure.
Plastic film: Plastic film is often used as the airtight layer of the inflatable airbag. It has good airtightness and can effectively prevent the leakage of the inflatable airbag. This feature is essential to ensure the inflation effect and durability of the airbag.
Rubber: Rubber is an important raw material for the production of inflatable airbags, and common ones are natural rubber and synthetic rubber. Rubber has good elasticity, wear resistance and chemical resistance, and can be used to make the airtight layer of the airbag. The use of rubber enhances the sealing and durability of the airbag.
Connectors: The production of inflatable airbags also requires some connectors, such as zippers, buckles, ropes, etc., in order to fix and use the inflatable airbags. The selection and use of these connectors are also related to the overall performance and safety of the airbags.
2. Welding and heat sealing technology
In the manufacturing process of inflatable airbags for car seat backrests, welding and heat sealing technology is an important process. This technology is mainly used for the connection and sealing of airbags to ensure the integrity and airtightness of airbags.
Airbag connection process:
Ensure that the materials of the connection parts are compatible to improve the strength and stability of the connection.
The connection parts are cleaned to ensure that there are no impurities such as dust and grease on the surface.
Use a heat welding machine for connection. The materials of the airbag connection parts are melted and combined by heating, applying pressure and holding for a certain period of time.
Carry out quality inspection on the connection to ensure the firmness of the connection.
Airbag sealing process:
Select materials with good sealing properties.
Bond the edge of the airbag and the seat cushion of the seat to ensure that a seal is formed between the airbag and the seat cushion.
Heat and apply pressure in the heat seal welding machine to melt the materials and combine them together to complete the sealing of the airbag.
Technical points:
Select a suitable heat seal welding machine to ensure that it has stable temperature control and pressure control functions.
Reasonably select the temperature and time parameters of heat seal welding according to actual needs to avoid overheating or insufficient welding quality.
Strict quality inspection of materials and adhesives at the connection parts to ensure the reliability and sealing of the connection.
Quality inspection of the airbag after welding to ensure that the welding effect meets the requirements.
Through the above material details and the introduction of welding heat sealing technology, we can better understand the manufacturing process and technical requirements of the car seat back inflatable airbag. This information is crucial to ensure the quality and performance of the airbag.
