Ultrasonic Welding Machine for ABS Plastic

Adjustment of Ultrasonic Welding Machine for ABS Plastic and preparation work before fusion:
(1) First, clean the ultrasonic transducer, welding head (HORN), and welding head screws with alcohol or gasoline. Then, apply a thin layer of yellow grease to the welding head screws, transducer, and welding head joint surface, and lock the welding head screws onto the welding head. Attention: If there is damage to the joint surface between the transducer and the welding head, the transmission efficiency of vibration will decrease, and it should be maintained carefully.
(2) Tighten the four welding head horizontal adjustment screws again and fix the transducer in the middle position of its rotation range.
(3) Rotate the welding head into the transducer by hand until it cannot rotate.
(4) Use a welding head locking wrench to tighten the welding head (with a torque of about 300 kg/cm). At this time, be particularly careful not to let the transducer rotate to prevent the rotating tip from breaking. (If rotation is found, the horizontal adjustment screws of the four welding heads need to be tightened further.).

FAQ

Q：Can Ultrasonic Welding Machine for ABS Plastic press plastic?
1. Conducting energy through vibration.
2. Thermal energy directly comes into contact with the surface of plastic products. These two points are two situations that ultrasonic welding machines may encounter during operation, so it is easy for welding components to be scalded. For plastic parts with thinner walls, they are prone to cracking. These are all unavoidable. There are other reasons that can cause cracks or ruptures, which can be avoided. For example, sometimes when the power is insufficient, it is mostly through long-term welding to accumulate heat to compensate for insufficient power. This will cause heat to act on the surface of plastic parts for a long time, resulting in product burns and other phenomena, which can be completely avoided.

• Solution:

1. Reducing the welding time requires reducing the time that heat acts on plastic parts.
2. Start vibration early.
3. Reduce stress.
4. Reduce delay time (early vibration).
5. Cover with reference media (such as PE bags).
6. Add an R angle at the right angle for products that are prone to breakage.
7. Surface treatment of mold fixtures (hardening or chrome plating).
8. The number of machine sections is reduced or the upper mold expansion ratio is reduced.
9. Fixtures should be made into cushioning products that are prone to cracking or breakage. Such as soft resin or covered cork plugs (this refers to not affecting the welding strength).
