RINGA machine is an integrated high frequency welder for PVC eyelets with automated pneumatic feeding/punching press for large volume welding of plastic eyelets onto various technical textiles.
Compared to metal grommets, welded plastic eyelets will fuse together with the fabric and result in a joint that is significantly stronger and can withstand significantly higher pull forces. This is especially true when working in mesh materials.
RINGA machine offers single side high frequency welding for PVC eyelets of various diameters e.g.: 11/27, 13/32, 15/37, 19/43mm (inside/outside) with customized electrodes.
RINGA punch/weld machine is designed to work with Carmo PVC and plastic eyelets which are typically used for reinforcement of holes in foils and fabric in building wraps, banners, outdoor advertisings, tarpaulins, tents, billboards, tensile structures, netting, water sport equipment.
Carmo eyelets are made from a special formulation and are used worldwide for strong, flexible and durable reinforcement of holes. Clear, grey, white. Other colours available upon request. PVC eyelets offer more advantages for the outdoor banner producer, e.g.: no hemming required, the only solution for single layer vinyl. “Invisible” placement of eyelets on the back of the banner is possible.
They will not rust, tear through the reinforced fabric and their tensile strength is much greater than metal eyelets.
Full diagnostic testing and certification of the local factory EMC/EMS parameters according to the latest guidelines required by the CE & UL standards. We have our own ISO 17025 certified production control and EMC laboratory providing validation of each required process parameters and the whole technological production cycle.
High frequency welders manufactured by Zemat Technology Group are designed and built in accordance with current European requirements for machine safety and energy efficiency. The machine design incorporates technical solutions that enhance welding process stability, reduce energy losses, and increase production repeatability.
HF Smart Control™ is a set of structural and electronic solutions implemented in high frequency welders, including:
The HF/RH welders use high frequency generators with microprocessor-based power control, enabling precise adjustment of energy to the process parameters. The system continuously monitors operating conditions and dynamically regulates power in real time. As a result, energy consumption can be reduced compared to heat sealing technologies and many impulse-based systems. The actual level of savings depends on the material, application, and process settings.
The ATS ensures precise impedance matching and automatic generator tuning during machine operation. This stabilizes the welding process, reduces the risk of instability, and minimizes the possibility of arcing. Fast reflected power control protects HF circuit components and improves weld repeatability.
Modern HF generators achieve energy efficiency levels of approximately 70–90%, depending on configuration and operating conditions. Band-pass filters reduce harmonic distortion, while lower thermal losses decrease heating of machine components. This results in stable operation and extended service life of key components.
