The design of the ultrasonic mold is not reasonable enough, the manufacturing is not precise enough, and the optimal frequency is not reached when the frequency is trimmed, so the ultrasonic energy is not completely released during the application process, and then most of it stays in the ultrasonic mold, and the mold will appear to be weakly welded over time. After the mold heats up, the mold will show cracks. To deal with this problem, you must first select a professional ultrasonic welding machine manufacturer to manufacture the ultrasonic mold. The experience absolutely occupies more than half of the success and failure, and then whether the master is in accordance with the design when manufacturing. To manufacture, whether there are multiple trimming frequencies to make the mold reach the best condition.
by the low density of 6061, it also has outstanding corrosion resistance. It has outstanding generalized mechanical properties and cutability at room temperature. Steel molds and titanium alloy molds are more simple to make molds. Because they are harder and more difficult to cut, they are generally used to make relatively flat molds. The service life of titanium alloys on these three materials is The highest, almost no cracks, is also the most expensive of the three in terms of price.
The above is the reason why the welding head of the ultrasonic welding machine is easy to crack. I hope it will be helpful to everyone.
Do you know the reason why the welding head of ultrasonic welding machine is easy to crack? Let's take a look at it with the editor below
The simple crack of the ultrasonic mold is mainly caused by two major aspects:
In the selection of ultrasonic molds, the three most common materials used in ultrasonic mold manufacturing are steel, magnesium-aluminum alloy, and titanium alloy. There are big differences in magnesium-aluminum alloy. Generally, imported 7075 is used for manufacturing. Aluminum alloy is wear-resistant, corrosion-resistant, and has good mechanical properties. The hardness is slightly higher than other aluminum alloys. It is the best choice for ultrasonic molds and relatively high in price. It is generally used in aircraft structural parts.
