The welding head mold of the ultrasonic welding machine is the part of the ultrasonic energy output. Many ultrasonic welding machines have different treatments on the surface of the mold. The final effect of the surface treatment is to make the mold wear-resistant, corrosion-resistant, increase hardness, and improve aesthetics. First of all, the ultrasonic welding machine mainly uses three materials to manufacture: steel alloy, aluminum alloy and titanium alloy. The surface treatment process of different materials is different. Today, Linke takes everyone to understand the surface treatment process and material characteristics of ultrasonic molds.

   Steel alloy: Heat treatment improves the hardness, and the nickel plating on the surface not only prevents rust, but also exerts a certain aesthetic effect.

  Aluminum alloy: generally anodize the surface to prevent corrosion, especially hard anodize to increase the surface hardness to prevent surface corrosion.

  Titanium alloy: It does not require any treatment and is itself a kind of anti-corrosion material. After cutting, it has a good metal texture, which can increase the beauty.

The characteristics of three kinds of ultrasonic welding head mold materials:

   1. Advantages of steel alloy molds: the hardness increases after heat treatment, and it is the most wear-resistant of the three materials.

   Disadvantages: difficult to cut, the mold itself heats up high, and it is easy to damage other parts.

   2. Advantages of aluminum alloy molds: low hardness, suitable for cutting and engraving processing, at the same time, mechanical conductivity is also better than steel alloy molds, less heat.

   Disadvantages: In addition to the problem of the material itself, the matching problem of mechanical properties is short in life, low in hardness, and poor in wear resistance.

  3. Advantages of titanium alloy mold: good mechanical conductivity, hardness higher than aluminum alloy but lower than steel alloy, wear resistance of aluminum alloy is higher than steel alloy but lower than steel alloy, and the service life is almost not bad.

   Disadvantages: high raw material cost and poor wear resistance.
