What are the production process and heat sealing advantages of medical device leg bags

In the production of medical device leg bags, the high-frequency heat sealing machine achieves heat generation through the polarization friction of plastic material molecules by high-frequency electromagnetic fields, and completes the welding under the pressure of the mold. Its specific production process and advantages are as follows:

Production process
Equipment preparation: The high-frequency heat sealing machine uses a self-excited oscillator of an electron tube to generate a high-frequency electromagnetic field. The output power is strong and meets the international industrial band standards. It has safety protection measures such as a highly sensitive spark protection device and a current limiting protection device.
Mold installation and debugging: Install a suitable mold according to the shape and size of the leg bag, and debug the gap and position of the upper and lower molds.
Material placement: Place the cut plastic material (such as PVC, TPU, etc.) into the mold.
Heat sealing operation: Start the equipment, and the object to be processed is subjected to the action of a high-frequency electromagnetic field. The internal molecules are polarized and rubbed to generate heat, and the object is welded under the pressure of the mold.
Remove the finished product: After the heat sealing is completed, turn off the equipment and take out the welded leg bag product.
Advantages
High efficiency and automation: It can complete material welding in a very short time, improve production efficiency, and meet the needs of large-scale industrial production and small-batch customized processing. The equipment has a high degree of automation, is easy to operate, and reduces manual intervention.
High quality and high reliability: By precisely controlling the high-frequency electromagnetic field parameters, a uniform and firm welding effect is achieved, the welding point is flat and smooth, with high strength, and it is not easy to crack or degumming, ensuring stable and reliable product quality.
Material compatibility: It supports a variety of plastic materials, such as PVC, TPU, EVA, etc. It can also be used for the composite processing of materials such as leather and cloth with plastics, and plays an important role in medical packaging and medical plastic welding.
Safety performance: It is equipped with anti-radio interference devices, spark suppression and safety devices, etc. to minimize high-frequency interference, effectively solve the impact of high-frequency interference on other machines or human bodies, and avoid damage to molds and materials due to sparks.
Process flexibility and personalized customization: Molds of various shapes and sizes can be designed and manufactured according to different product requirements. Whether it is a complex three-dimensional structure or a special shape of the product, efficient welding can be achieved through suitable molds, which has unique advantages for small batch and personalized customized production.
Energy saving and environmental protection: It can heat materials in a concentrated manner in a short time. Compared with traditional heating methods, it has higher energy utilization, reduces energy waste, reduces production costs, and also helps to reduce the energy consumption burden on the environment. Its precise heating control can also avoid overheating, further improving the rationality of energy utilization.
