1. What materials can be welded by ultrasonic welding machines?
1. Ultrasonic welding machines use ultrasonic vibration and pressure to connect two objects together. It uses high-frequency ultrasonic energy to generate localized heat to rearrange the molecular structure of an object and weld it without the need for additional welding materials.
2. Metal materials, including brass, copper, aluminum and aluminum alloy. Non-metallic materials, including CYCOVIN, KYDEX, NORYL, PC, PE, PP, PS, POLYSULFONE, PVC, SAN, POLYESTER, XT-POLYMER, ABS, ACETAL, ACRTILCS, CELLULOSICS.
3. POM, SAN, PP, PVC, PMMA and other materials, that is to say, it is possible to use ultrasonic welding machines to complete the welding action to make products with these materials, but although some of these materials can be welded with ultrasonic welding machines, some of the welding effects are difficult to meet the requirements, that is to say, it is difficult to weld.
4. What materials can be welded by ultrasonic welding machine?Ultrasonic welding machine can weld a variety of materials, it is recommended that you choose three materials: ABS, PS, SNA. These three materials are recognized as the more suitable materials for ultrasonic welding. SNA: Ultrasonic welding effect is good.
5. The materials that can be welded by the ultrasonic welding machine are also required, such as hard materials ABS, PP, PC, etc., which are more suitable for ultrasonic welding, and the effect is also better.
2. What kind of material is the ultrasonic sonotrotode?
1. Ultrasonic welding head is also called ultrasonic mold, there are many materials for ultrasonic welding head, aluminum alloy, titanium alloy, etc., to say that the wear-resistant one is titanium alloy, there are more introductions to this aspect.
2. Ultrasonic welding head is divided into three types according to the mold material: aluminum-magnesium alloy mold, which is used for the manufacture of vibration system (luffing rod) and sonotrode head, which has extremely high mechanical yield strength, high hardness and strong thermal conductivity, and is an ideal ultrasonic mold manufacturing material; However, aluminum is not wear-resistant and suitable for general welding requirements.
3. Ultrasonic sonotrode is an indispensable and important part of ultrasonic welding equipment. Its function is to couple the ultrasonic waves generated by the transducer into the processed object, and because it is used to transmit ultrasonic waves, the sonotrode must work in a resonant state.
4. At the same time, the wear resistance of the sonotrode can be greatly increased by specific surface treatment on the surface of the sonotrotode. It is often used for welding plastics containing fiberglass. Alloy steel: used for welding plastic parts that cannot be applied to aluminum alloy and titanium alloy, it has high hardness and higher wear resistance, and is generally hardened before use.
5. The material of the commonly used ultrasonic welding machine welding head is as follows: about 75% of the ultrasonic welding head is made of titanium, about 15% is made of aluminum, and the other welding heads are made of hardened steel of HRC54-5. Titanium is an ideal material with light weight, appropriate hardness, good toughness and excellent acoustic performance, which is often used in small welding heads, and titanium can also be coated with cemented carbide for high wear occasions.
6. Multiply the welding head (2) the selection of the welding head: the daily welding head mostly uses titanium alloy, aluminum alloy, and steel as raw materials, and now most of the machines use high-quality imported 7075 aluminum alloy, which has good mechanical strength, hardness and thermal conductivity, and the price is reasonable, it is the best material for the welding head of ultrasonic plastic welding machine.
