High-frequency welders are machines designed for packaging PVC (polyvinyl chloride) based materials, mainly used in the form of sheets or large sheets.
The sturdiness of the machine and of all the electromechanical and pneumatic components used in its construction, which comply with standards and are largely oversized, give the welding machines a high degree of reliability.
Proper logistic support makes it possible to minimize the risk of machine downtime, thus guaranteeing programmable production with extremely low risks.
These machines are therefore designed to operate safely, in compliance with the EEC directives in force concerning machines with a medium-low risk level.
The technology used by these machines is based on 3 fundamental parameters:
- Pressure
- Power
- Time
The material to be welded is placed on the work surface, pressed by the welding electrode to which high-frequency (27.12 MHz) power (or welding current) is applied for a defined time.
The material thus becomes the high-loss insulator of a capacitor in which the POSITIVE pole is the WELDING ELECTRODE (or MOLD), and the NEGATIVE pole is the work surface.
When the high-frequency current flows through the PVC molecules, they join together to form a single body.
By mixing these 3 parameters, PRESSURE, POWER, TIME, it is possible to obtain excellent welding quality.
Thanks to this special technology, HIGH FREQUENCY JOINTING of PVC sheets is absolutely the best welding possible for this product.
