1.High-frequency oscillation:
The high-frequency generator inside the equipment generates high-frequency current, which is input into the mold through a specific conduction system to form a high-frequency electromagnetic field.
2.Molecular vibration and heating:
Under the action of the high-frequency electromagnetic field, the molecules inside the TPU (or other plastic) material vibrate rapidly and rub against each other, generating heat, causing the material to quickly heat up to the melting point.
3.Fusion sealing:
Under the pressure and temperature control of the mold, the material heated to the melting point quickly fuses and solidifies to form a solid fusion layer or seal.
1.Efficient automation:
The equipment adopts a fully automatic turntable design, which can achieve continuous and efficient automated production. The four-station design doubles the production efficiency, greatly saving manpower and time.
2.Precise control:
With the help of PLC programming and microcomputer touch screen control system, the operation is simple and accurate. Users can easily set parameters such as welding time, temperature, pressure, etc. to ensure that each welding achieves the best effect.
3.Wide application:
The equipment is designed for continuous welding of various materials such as PVC, EVA, TPU, etc., and is widely used in automotive accessories (such as seat lumbar support airbags) and other fields.
4.Reliable quality:
The equipment is made of high-quality materials and advanced technology, and the structure is stable and durable. At the same time, it also has the function of cold cutting automatic trimming to ensure that the welding part is flat and beautiful.
1.Place the plastic material to be welded (such as TPU airbags) in the mold.
2.Start the equipment, the equipment generates high-frequency electromagnetic waves, penetrates the plastic material and makes its internal molecules vibrate to generate heat.
3.When the temperature reaches the melting point of the plastic, the material begins to weld. At this time, the mechanical pressure system applies pressure to make the welded part more solid.
4.After welding is completed, the equipment automatically cools and shapes to ensure the quality of the welding part.
5.The welded products are transported to the next station or collection area through the automatic turntable.
1.Before use, please ensure that the power supply, air pressure and other connections of the equipment are normal, and check whether the mold is installed in place.
2.According to the type and thickness of the material to be welded, reasonably set the welding time, temperature, pressure and other parameters.
3.During the operation, please pay attention to the operating status and welding quality of the equipment. If there is any abnormality, please stop and check in time.
4.Maintain and maintain the equipment regularly to ensure its long-term stable operation.
The four-station turntable heat sealing machine has significant advantages in the heat sealing of automobile seat lumbar support airbags and is an indispensable and important equipment in the production of automobile interiors.
