Why is heat treatment necessary when operating ultrasonic molds? Ultrasonic molds are often heat-treated during the production process. Most of the steel molds that are usually made are made of coiled steel. If there is no hardness, it will not be punched several times, and the edge of the mold will be blunt, and it will not be able to punch. The mold is also easily deformed.

The molds made with a lot of effort will not be usable after a long time, which is too costly. Therefore, the produced mold must be quenched to extend the service life of the mold as much as possible to achieve better economic benefits. At the same time, the internal performance of the mold can be changed after heat treatment, and the resistance can be reduced. Proper heat treatment of the steel can significantly increase the hardness, strength, and toughness. , Mechanical properties such as wear resistance.

Ultrasonic mold is a general term for all ultrasonic transmitters, and its function is to couple the ultrasonic waves generated by the transducer to the processed object. Because it needs to transmit ultrasonic waves, the mold must also work in a resonant state, that is, its natural resonant frequency must match the vibrator. Secondly, the amplitude must be uniform, and the shape of the end face must be adapted to the shape of the tool to be welded.

1. Frequency range: 15KHz-100KHz

2. Material: alloy steel, aluminum alloy, titanium alloy, stainless steel.

3. Hardness: greater HRC62°

4. Working medium: solid, liquid, liquid metal, etc.

5. Surface treatment: blackening, polishing, chrome plating.

Alloy steel, aluminum-magnesium alloy, titanium alloy aluminum-magnesium alloy (7075-T651, 2024-T651, 6061-T651) are mainly used for welding and welding of plastics and plastics. Titanium alloy die heads are mainly used for riveting points, such as the welding heads of ultrasonic spot welders, which are used for welding and riveting interior parts of automobile door panels.

Alloy steel is mainly used for products where ultrasonic welding and cutting are completed at the same time. It is easy to crack if it is not done well.
