The thermal sealing process of the automatic rapid stacking door is an important step to ensure the close connection of all parts of the door body and improve the overall performance.
The following is a clear introduction to the process, including point representation and induction:
Overview of hot joint processing technology
Thermal bonding process is a process that uses heat energy to heat two or more material surfaces to a certain temperature, and then makes them closely connected under pressure.
In the manufacturing process of automatic rapid stacking door, the thermal sealing process is mainly used for the connection of door body, door frame, sealing strip and other components.
Hot sealing process steps
Material preparation: Select materials that meet the requirements, such as high-strength aluminum alloy, sealing strips, etc., and carry out necessary pretreatment, such as cleaning, drying, etc., to ensure that the surface of the material is clean, free of oil and impurities.
Commissioning of hot sealing equipment: Check the working status of hot sealing equipment, including temperature control system, pressure control system, etc., to ensure the normal operation of equipment.
According to the characteristics and requirements of the material, set the appropriate heat sealing temperature, pressure and time parameters.
Material positioning: Place the parts that need to be hot closed on the hot closing device according to the design requirements to ensure that the positions between the parts are accurate and aligned.
Start the hot bonding equipment to heat the material. When the material reaches the set temperature, a certain pressure is applied to make the surface of the material close contact, melt and bond together.
Keep for a certain time, so that the molten part is fully cured and firmly connected.
Check and repair: After the hot sealing is completed, check the connected part to ensure that there are no bubbles, no impurities, and the connection is firm. If necessary, it can be properly trimmed and polished to improve the appearance quality and connection performance.
Key points of hot bonding processing technology
Temperature control: The thermal sealing temperature is a key factor affecting the quality of the connection.
High temperature may lead to material deformation and burning; Too low a temperature may cause the connection to be weak.
Therefore, it is necessary to strictly control the thermal sealing temperature to ensure that it is within the appropriate range.
Pressure control: Appropriate pressure ensures that the material surfaces are in close contact, fused and bonded together. Excessive pressure may lead to material deformation and rupture; Too little pressure may result in a weak connection.
Therefore, it is necessary to set the appropriate pressure parameters according to the characteristics and requirements of the material.
Time control: The length of heating and holding time also affects the quality of the connection. Too short a time may lead to a weak connection; If the time is too long, it may cause the material to burn and aging.
Therefore, it is necessary to strictly control the heating and holding time to ensure that it is within the appropriate range.
The thermal sealing process of the automatic rapid stacking door is an important step to ensure the close connection of all parts of the door body and improve the overall performance. By strictly controlling parameters such as temperature, pressure and time, you can ensure the stability and reliability of the connection quality.
At the same time, reasonable material selection and pretreatment, equipment debugging and inspection are also the key to ensure the quality of hot joint processing.
