1. Material preparation
Ventilation bag materials: usually use materials with good air tightness and air permeability, such as airtight non-woven fabrics, TPU films, etc. These materials can ensure that the ventilation bag is not easily damaged during use and has good ventilation effect.
Welding materials: According to the material and design requirements of the ventilation bag, select suitable welding materials, such as heat-sealing glue, welding wire, etc.
2. Welding equipment
Heat-sealing welding machine: The welding of automobile seat ventilation bags mainly depends on heat-sealing welding machines. This equipment melts and combines the ventilation bag materials by heating, applying pressure and holding for a certain period of time.
High-frequency welding machine: Some high-end ventilation bags use high-frequency welding technology, which uses high-frequency electromagnetic fields to promote molecular flow penetration and achieve simultaneous melting. This technology can ensure the firmness and beauty of welding.
3. Welding process
Cleaning treatment: Before welding, the connection parts of the ventilation bag need to be cleaned to ensure that there are no impurities such as dust and grease on the surface to improve the welding quality.
Welding: According to the design requirements of the ventilation bag, select appropriate welding methods and parameters, such as welding temperature, time, pressure, etc. Then, place the connection part of the ventilation bag on the workbench of the heat sealing welding machine or high-frequency welding machine for welding.
Quality inspection: After welding, the ventilation bag is quality inspected, including air tightness test, strength test, etc., to ensure that the welding quality meets the requirements.
IV. Precautions
Choose a suitable welding machine and welding materials to ensure welding quality.
According to the material and design requirements of the ventilation bag, reasonably set the welding parameters to avoid overheating or insufficient welding quality.
Carry out strict quality inspection on the materials and adhesives of the connection parts to ensure the reliability and sealing of the connection.
Regularly maintain and maintain the welding equipment to ensure the normal operation of the equipment and the welding quality.
V. Summary
The welding production process of the automobile seat ventilation bag is an important link in the production process of the ventilation bag. By selecting suitable materials, equipment and process parameters, as well as strict quality inspection and control, it can ensure that the welding quality of the ventilation bag meets the requirements and provide passengers with a comfortable and safe riding environment.
