Matrelec High Frequency and Impulse Welders

Matrelec specialises in the manufacture of high-frequency or impulse welding machines. Designed and manufactured in France since 1989, Matrelec welders offer versatile, reliable and high performance welders at a competitive price.

HF welding is widely used with technical textiles for welding truck tarpaulins, water tanks and dam liners, swimming pool covers and liners, shade structures, café curtains and tension membranes. Other jobs which are ideal for HF welding include inflatable products such as mattresses, life jackets, air bags, inflatable dinghies and survival products.

Medical products made with HF welding include gastric balloons, blood bags, disposable PPE, HAZMAT and nuclear garments, CBRN suits, orthopaedic products, inflatable structures, blood pressure cuffs, inflatable beds and cushions. HF welding is also used for blister packs and other types of plastic packaging.

Matrelec welders can be equipped for impulse welding making the machine suitable for precise welding of thin materials. With the high cycle times possible with impulse welding, the process is suitable for food, medical, cosmetic and automotive work. 

The compact foot operated CCM30 with 3kW output and 80cm² welding area is perfect for small medial and packaging products or detail work in PPE, hazmat suits, medical and packaging. 

The C-750 welders with 750mm behind the electrode and 10-15kW of power, make welding larger, bulky products quick and easy.  With a quick-change electrode up to 1500mm or 500cm² this welder can handle the toughest work.

The CP welders have 1500mm behind the electrode for rolling large products and 10-15kW of power for big jobs. CP welders can be configured for front or side operation and have air-cooled electrodes for consistent welds.

The CCM30 can be configured with a wide range of fixed and rotary tables and interchangeable tools for fast precise work with small flat items like handles, eyelets and valves as well as tubular products like gloves.  

Q welders with 8-12kW power, fitted with a transfer table for reduced cycle times are the first step in more automated welding of products from PVC to medical and packaging.

Higher power welders can be fitted with long transfer tables either side or one or more welders can travel over a table for working with truck side curtains, roller doors, shade structures and other PVC work.

High-frequency welding is a process based where high-frequency electrical oscillations are used to melt and fuse plastic materials. The main feature of HF welding is that a uniform, controlled temperature is achieved in the material being welded creating a good join without damaging the material. 

HF welding has considerable advantages over hot air welding. It's a simple process, requiring less skill. Good, consistent results are easy to achieve. While hot air welding applies heat to the exterior of the welded region, HF welding generates heat within the weld giving a stronger and more reliable bond. HF welding uses lower energy than hot air welding and doesn't produce toxic gasses.

Impulse welding is a thermal welding process in which a thin stripe heating element is heated by short power pulses directly at the weld zones.

The process is similar to high-frequency welding and can often be done on the same machine. The welding and cooling cycles are precisely controlled, as the blade rises and falls in temperature very quickly.

The process is effective on thin materials when compared with HF welding and is best suited to smaller, precise welds where a high production rate is necessary.

Tools for impulse welding can be more complex and costly than HF tools.
