INGA machine is integrated HF welder 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 HF welding for PVC eyelets of various diameters e.g.: 11/27, 13/32, 15/37, 19/43mm (inside/outside) with customized electrodes.


INGA 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.


armo 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 offers 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.
