Overview
About this machine
What the CORNA high frequency welder makes
The Zemat CORNA is a high frequency (HF) welder for small, complex, three-dimensional welds in technical textiles. It makes inner and outer corners for membranes and tents, corner shapes for side and roof truck covers, caps for containment pools and oil booms, triangular fastenings and corners for tensile structures, reinforcements for water and fuel bags, and welded handles and grips. The column design of the head and footing reaches into corner geometry that a flat work table cannot.
Buyers describe this kind of machine as a high frequency welder for complex shapes, a corner welding machine, a 3D HF welder, or a multilayer welding machine. It is the tool for the welds that sit at an angle, in a corner, or through several layers of coated fabric.
Built for technical-textile fabricators in India
The CORNA suits fabricators who already make flat welds and need a dedicated machine for the corners and reinforcements: tent, awning and tensile-structure makers, truck cover and tarpaulin fabricators, producers of inflatable and containment products like pool liners and oil booms, and manufacturers of industrial bags, water and fuel storage bladders. It welds up to 8 layers, so heavily reinforced fastening points are no problem.
It is built to be easy to live with on a busy floor: a small footprint, great work ergonomics, pedal or toggle action to cut operator fatigue, and an option to put it on wheels and move it to wherever the work is. Custom electrodes are made to the shape of your product, and the FlexEL flexible electrode handles changeable-layer welds, going from a 2-layer weld up to 8 layers and back without a tool change.
What high frequency welding can and cannot join
HF welding works on polar thermoplastics: PVC, polyurethane (PU and TPU), PET and many coated technical fabrics, which is exactly what tents, covers, booms and bags are made from. It does not weld non-polar plastics such as polypropylene (PP) or polyethylene (PE), which do not heat under an HF field. If you are unsure whether your coated fabric welds, send Zemat a sample and they will test it.
What the CORNA helps you produce
- Tents and membranes: inner and outer corners, triangular fastenings and reinforced fixing points.
- Truck and side covers: corner shapes for roof and side curtain covers.
- Containment products: caps and corners for pools, oil booms and water or fuel storage bags.
- Fittings: welded handles, grips and reinforcement patches on technical-textile products.
Why source the CORNA through Magnum Resources
Magnum Resources is the authorised India partner for Zemat Technology Group. One team handles the whole chain: sizing the machine and the custom electrodes with the Zemat factory for your products, managing import and customs, installing it on your floor, and training your operators at start-up. Wear parts and technical support run through the same contact afterwards. If you make tents, covers, tensile structures or industrial bags and the corners are slowing you down, talk to our engineers about your product shapes and layer counts.

Return on Investment
What this machine saves you
The numbers Indian manufacturers use to justify the CAPEX internally.
Up to 8 layers
Multilayer Corner Welds
Weld up to 8 layers of coated fabric in one corner or fastening point, so heavily reinforced fixings are no longer a hand-finishing job.
Any Shape
Custom Electrodes
Electrodes are cut to the shape of your weld (round, triangular, oval), and the FlexEL electrode covers changeable-layer work without a tool change.
Mobile
Compact Footprint
A small floor footprint and optional wheels let you place the CORNA at the workstation where the corner work happens, not in a fixed bay.

FAQs
Questions Indian buyers ask us
Real questions from our last 50 enquiries, answered upfront.
The CORNA is built for small, complex, three-dimensional welds in technical textiles: inner and outer corners for tents and membranes, corner shapes for truck covers, caps for containment pools and oil booms, triangular fastenings for tensile structures, water and fuel bag reinforcements, and welded handles and grips. Its column design reaches corner and conical geometry that a flat-table welder cannot.
The CORNA makes multilayer welds of up to 8 layers, which covers heavily reinforced corners and fastening points. It works on polar thermoplastics: PVC, polyurethane (PU and TPU) and PET, including coated technical fabrics. It does not weld non-polar plastics such as polypropylene or polyethylene. The FlexEL flexible electrode lets you move between 2-layer and 8-layer welds without changing tools.
Corners and 3D shapes are hard to weld on a flat table because the fabric has to fold and sit at an angle. The CORNA puts the welding head on a column over an open footing, so the part can wrap around and be welded from the right direction. That is what makes inner and outer corners, caps and triangular fastenings practical to produce in volume.
Yes. CORNA electrodes can be cut to custom shapes (rectangular, round, triangular or oval) to match the look of the finished weld. Zemat makes the tooling, and the FlexEL flexible electrode covers changeable-layer work. Send us your product drawings and we will scope the electrodes with the factory.
The main buyers are tent, awning and tensile-structure makers, truck cover and tarpaulin fabricators, producers of inflatable and containment products such as pool liners and oil booms, and manufacturers of industrial bags and water or fuel bladders. It suits fabricators who already weld flat seams and want a dedicated machine for corners and reinforcements.
The CORNA uses a new-generation Hi-Q3 HF generator rated at 4 kW, sized for small, precise welds rather than large flat seams. It has a deliberately small footprint with good work ergonomics, a freestanding HMI control panel, and can be fitted with wheels so you can move it to where the work is.
The CORNA is made to CE regulations and tested according to ISO 17025, and Zemat runs its own ISO 17025 certified EMC laboratory with onsite EMC testing available for CE and UL standards. The Hi-Q3 generator is designed for minimum operator RF exposure, and safety comes from a protective fixed guard with an HF shielded and filtered work table, the ZTG AntiFlash ARC sensor with overload protection, the ZTG SafeDown anti-crush electrode system, a grid filter, safety switches and backflow HF emission protection.
Typical lead time is around 16 to 20 weeks: build and EMC testing at the Zemat factory in Poland, then sea freight and customs into India. Magnum Resources manages the import, customs clearance, delivery, installation and operator training at start-up. Spares, custom electrodes and technical support stay with the same Magnum contact after the machine is brought online.
