Ultrasonic steel mold is a kind of ultrasonic mold. Why do ultrasonic steel molds need heat treatment?
The ultrasonic steel mold is made of chromium steel. If the hardness is not enough, the cutting edge of the mold will be dull after using it many times, the product cannot be washed away, and the mold is also easy to deform. Therefore, the produced mold must be quenched to extend the service life of the mold as much as possible. At the same time, heat treatment can change the internal performance of the mold and reduce impedance. Proper heat treatment of mold steel can significantly increase mechanical properties such as hardness, strength, toughness, and wear resistance. .
The heat treatment process of ultrasonic steel mold is composed of three stages: heating, heat preservation and cooling. The purpose of ultrasonic steel mold heat treatment is to increase the hardness and change the crystal structure inside the material itself to make it wear-resistant and facilitate ultrasonic transmission.
At present, the treatment of ultrasonic steel molds usually adopts blackened surface treatment or electroplating hard chrome treatment.
