How is the ultrasonic mold made?

The design and manufacture of ultrasonic mold is a very complicated work, which needs to be considered comprehensively according to the mold material, size, mechanical frequency and acoustic principle. What you need to pay attention to when making ultrasonic molds is the material and frequency. Frequency needs professional testing instruments to complete. Ultrasonic mold material: 1. Aluminum alloy (7075,2024,6061); 2.SCM8: generally used for inlaying screws and metals, with good toughness and high hardness, and the thermal conductivity is second only to 2024; Three, titanium alloy: generally used for continuous vibration opportunities, high toughness, good thermal conductivity, high hardness, and expensive. Shenzhen hongda ultrasonic science and technology professional ultrasonic mold, ultrasonic mold production. Simply put, the purpose of grooving ultrasonic die is to destroy the shear wave produced in ultrasonic transmission. Slotting is generally at 1/2 shear wave wavelength, which is mainly considered according to acoustic principle. As for why we should make molds with different widths, the main consideration is to increase the output, and the principle is similar to amplifying the output of sound waves. A good mold is the most important prerequisite for welding stability. If the ultrasonic die design is not good, it will lead to a series of welding problems such as uneven welding, die heating, noise and even cracking.
