Heat treatment is often carried out during the production of ultrasonic molds. Most of the steel molds usually made are made of stainless steel. If there is no hardness, the edges of the molds will be blunt after several times of punching, and the molds will be easy to deform. The mold made with great efforts will not be used for a long time, which is too uneconomical. Therefore, the produced mold must be quenched to prolong the service life of the mold as far as possible and obtain the best economic benefits. At the same time, the internal performance of the mold can be changed and the resistance can be reduced after heat treatment. The mechanical properties such as hardness, strength, toughness and wear resistance of steel can be significantly increased after proper heat treatment.
Ultrasonic mold is a general term for all ultrasonic emitting ends. Its function is to couple the ultrasonic wave generated by the transducer to the object to be processed. 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 should be uniform, and the end face shape should adapt to the shape of the tool to be welded. 1. Frequency range: 15khz-100khz 2. Materials: alloy steel, aluminum alloy, titanium alloy and stainless steel. 3. Hardness: maximum HRC62 ° 4. Working medium: solid, liquid, liquid metal, etc. 5. Surface treatment: blackening, polishing and chrome plating.

Alloy steel, aluminum magnesium alloy, titanium alloy aluminum magnesium alloy (7075-t6512024-t6516061-t651) are mainly used for welding and fusion of plastics and plastics. The die of titanium alloy is mainly used for riveting, such as the welding head of ultrasonic spot welding machine, which is used for the welding and riveting of automobile door panel trim parts. Alloy steel is mainly used for ultrasonic welding and cutting products. It's easy to crack if you don't do it well.
