Our customers told us same questions about the Ultrasonic Plastic welder to sealing trading plastic slabs, Do you have the following questions?
David said “I just can’t imagine in todays market people will be sending them cards in the millions as it happened during the pandemic. It’s just not worth the flip with so many cards even if they can now handle it.”
Sytse said“ I do consider sending some cards in. It”s just that the label is kind of bland ,and most of all, the ink and lettering are not so clear. Everything seems to be of high quality except the label. Would love to see that improved”.

Facing such a big competition environment, the welding effect of ultrasonic welding machine is particularly important. Welding firmness, waterproof effect after welding, perfect effect after welding.
There are many things you may need to do to get a collectible plastic case, you need to choose a good quality plastic case, and the right welding machine. Quality plastic case included; Transparent plastic shell, translucent plastic, plastic shell material, plastic shell ultrasonic line design, plastic shell size and so on.
If the design height of the ultrasonic wire of the plastic shell is reasonable, generally the height of the ultrasonic wire is about 0.3-0.4mm. If the ultrasonic line is too low, the welding is not solid, if the ultrasonic line is too high, the glue overflow after welding, welding is not beautiful.
If the plastic material itself is too thin, it will take a long time to adjust the machine during the welding process. The thickness of plastic parts is one of the important reasons affecting ultrasonic energy conduction. The thickness of plastic parts makes it difficult to effectively transfer the energy to the welding surface, so it is difficult to achieve high strength ultrasonic welding. Plastic parts are thin, the energy is not easy to effectively control in the required range, shorten the time then ultrasonic welding strength is not enough, too long time will lead to ultra-thin plastic cracking.
Welding machine selection, generally recommended to choose 15khz 2600W plastic welding machine, and with time and energy mode. Welding mode is required with gentle and constant amplitude. The welded plastic shell is not only strong, but also beautiful to weld.
Our factory specializes in the production and development of ultrasonic plastic welding machine, and provides welding technical solutions for various industrial factories. If you need, we can provide you with the plan and price for free.
