High Frequency Welding Machine For Carpet

With the development of industry and commerce, the connection technology of products has gradually developed and changed. From traditional locking screws, instant glue, chemical solvents, and injection package melting, it has become the current ultrasonic vibration transmission, hot plate direct melting, high frequency, etc. Welding method. Because of the development of industry and commerce, the pursuit of high-efficiency production also needs to meet the needs of environmental protection. At present, the welding technologies that are frequently used in the production of the electronics industry include Ultrasonic Welding Machine, Hot Plate Welding Machine, High Frequency Welding Machine .

The difference between high frequency welding and ultrasonic welding

High-frequency welding and ultrasonic welding are two different concepts. High-frequency refers to electromagnetic waves with a frequency greater than 100Khz, and ultrasonic refers to sound waves with a frequency greater than 20 kHz. The high-frequency welding principle and welding principle are also different from ultrasonic waves. High-frequency waves use high-frequency electromagnetic fields to make the internal molecules of materials violently collide with each other to generate high temperatures to achieve the purpose of welding and welding. Ultrasound uses the principle of frictional heat generation to generate a lot of heat. To achieve the purpose of welding and welding.

Advantages and disadvantages of ultrasonic welding

Its advantage is the fastest production speed, generally welding and hardening can be completed in 0.4-1.0 seconds, without harmful chemical reactions and toxicity. The disadvantage is that below 15KHz, there will be more than 80 decibels of noise, the energy amplifier (upper mold) is limited by the conduction area, and higher toughness materials such as polypropylene PP, polyethylene PE, polyamide PA and nylon are not easy to weld. Parts after ultrasonic welding can be shipped without drying. The use of ultrasonic welding does not require the purchase and storage of welding rods, and does not use any chemicals and other solvents during the welding process, which is conducive to the improvement of the working environment and the recycling of plastics.

Advantages and disadvantages of high frequency welding

High-frequency welding uses positive and negative electrodes to produce a welding effect, and can also weld large products, but the materials are more likely to become embrittlement after welding using this welding method, and the cost of machinery and equipment is high, and electromagnetic interference is prone to disadvantages.
