HIGH QUALITY MACHINES
FOR HEATING ELEMENTS PRODUCTION
KANTHAL®MACEDONIA Machinery has a long experience in coil preparation and is able to propose a number of solutions in pin-coil welding.
According to the required production rates, these devices feature coil-pin-plug assembly units with manual, semi-automatic or full-automatic function.
The fully automatic version is designed to be a high-speed production unit for assembling and welding pins and coils and offers fast insertion of plugs into the upper end of the elements.
The machine is best suited for high volumes batches and can optionally be equipped with units for deformation of terminal pins, coil stretching, electrical test and other operations.
The unit assembles and welds two terminal pins to a coil as well as locating the bottom sealing plug onto the pin. Faulty or non assembled parts are automatically sorted out.
As an option, the KMMA can be equipped with resistance measuring (stretching the coil, measuring resistance and on the same time making a simple check that the coil is welded) of the ready unit after welding.
The normal cycle time is appr 3,5-4,0 s. Normal production during an eight-hour shift would be around 5000 – 6000 pcs.
This machine is only suitable for large batches, e g above 5 000 or 10 000 coils. Otherwise, the set-up time will become too important. However, if only the coil length varies, there is no need for a new set-up.
One week commissioning is a recommended option.
