FAQ：

Q: Can ABS and PC be welded together by ultrasonic plastic welding machine?

A: Yes, it can be welded. Theoretically, these two materials have good dissolution effect. In terms of materials, PC has better strength than ABS, but PC has one defect, that is difficult to eliminate stress and easy to crack. In ultrasonic welding, the stress cracking of PC is more obvious. By welding PC with ABS, the risk of PC cracking can be appropriately reduced with the help of ABS physical properties.

Q: Can polypropylene materials be welded by ultrasound welding machine?

A: PP plastic has no good ultrasonic transmission characteristics. Compared with ABS, PC, PMMA and other plastics, welding PP is more difficult. When using ordinary welding machines will be difficult to meet your welding requirements. However, jiayuanda team has rich experience in ultrasonic welding of PP materials. If you have PP plastic products that need to be welded, please contact us. We can choose the special ultrasonic welding grading card slabs machine model for you according to the specific product structure and requirements.

Q: How to debug an ultrasonic plastic welding machine?

1. Preparation work:

Ensure that the ultrasonic welding machine is connected to the power supply and grounded properly.

Inspect all parts of the equipment for damage and abnormalities, including welding heads, molds, power lines, and control systems.

Turn on the power switch, run the device without load for 5 minutes, and observe if there is any noise. If there is any noise, it should be eliminated first.

2. Ultrasonic welding head inspection:

Gently press the upper and lower mold seats with your fingers to ensure a good hand feel and not to loosen.

Check if the contact surface between the welding head and the secondary rod is clean, and apply a small amount of silicone oil or butter on both end faces to ensure a tight connection.

3. Mold temperature control:

The mold temperature is usually controlled between 40-50 ° C to avoid a decrease in plasticization efficiency and discoloration of the product surface.

4. Parameter adjustment:

Adjust parameters such as ultrasonic amplitude, welding time, and pressure according to the welding material and requirements.

Perform ultrasonic testing to ensure that the generator frequency is consistent with the mechanical resonance frequency of the transducer system.

5. Debugging and operation:

Place the two objects that need to be welded between the upper and lower molds.

Press the start button to start pressing down on the upper mold, making sure to press down to the bottom.

After waiting for the pressure gauge to display the normal value, keep the pressure gauge unchanged and continue to apply pressure until the ultrasound stops.

Remove the template, remove the product, and inspect its appearance and quality.
