Generator:

• The circuit adopts international advanced full-bridge voltage regulator circuit, and is optimized to achieve constant voltage output
• Automatic frequency tracking, no manual adjustment
• Voltage fluctuation can work range: 150-260V fluctuation period does not affect the output power and operating frequency.
• It has reached the international technical level of similar products.

Kneading system of ultrasonic transducer:

• Precision and stability of machinery.
• Fixed flange installation

Advanced ANSYS analysis system:

• Ultrasonic metal kneading energy exchange system, amplifiers, kneading top pole mold are strictly through the internationally recognized finite element software ANSYS for accurate design and analysis
• This test method can reach the level of foreign advanced counterparts in ultrasonic mold design,

Ultrasonic upper and lower poles (knead flat head)

• Strictly selected imported special die steel, wear resistance, high temperature resistance, good toughness, high mechanical rigidity, small deformation after heat treatment, so the ultrasonic output frequency consistency is high.
• The amplitude of mechanical high-frequency displacement is large, strong and stable.
• International leading professional heat treatment technology

Effect of flating:

• The surface after kneading is smooth, suitable for the laser kneading after the process.
