? FREQUENTLY ASKED QUESTIONS
What materials can this spot welder handle?
The machine is specifically designed for PP (Polypropylene) hollow boards, also known as corflute, coroplast, or correx corrugated plastic sheets.
Does the machine require glue or staples for bonding?
No. It uses ultrasonic vibration technology to fuse the material together at a molecular level, creating a strong bond without any consumables.
How many weld points can it perform per hour?
Depending on the operator and box complexity, the machine typically achieves a productivity rate of 700 to 1200 pieces per hour.
Is the welding depth adjustable for large boxes?
Yes. The cantilever structure provides a standard throat depth of 500mm, with custom frames available to accommodate heights and depths up to 1000mm.
Can the machine weld different thicknesses of PP board?
Yes, the ultrasonic power, welding time, and pressure can be adjusted via the digital control panel to suit various thicknesses and densities of corrugated sheets.
What are the main maintenance requirements?
Ultrasonic welders have fewer moving parts than traditional heat-sealing machines. Regular checks of the pneumatic system and ensuring the ultrasonic horn is clean and balanced are the primary maintenance tasks.
