In the field of pre-heating, heat treatments and welding processes, Seit Elettronica offers HF and MF induction heating equipment. Induction heating is highly repetitive once initial adjustments are made to the power supply. Following this phase, part after part can be heated with identical results, so long as the parts are introduced to the coil similarly each cycle. This can also lead to better material utilisation and product yield. The ability of induction heating to heat all parts identically lends itself to automation of the process. Induction heating can also heat the part in a highly localised fashion, which can be beneficial when it is desirable or necessary to limit the heat to only a certain region of the part. The location of the desired heat zone can be defined to a specific area on a workpiece in order to achieve accurate and consistent results. Induction heating equipment is instantly on, which means it requires no warm-up time, unlike conventional heating

sources. Induction heating systems are also energy efficient. With the development of an induction coil combined with the specification of the proper power and frequency, the user can isolate or pinpoint a heat- zone, small or large, without affecting surrounding areas. The result is minimal distortion in the part being

heated, yielding higher quality production. Additional infrared temperature control devices can be added for further control of the process.

Launch of first 3-axis-lump detector for transparent products

Sikora AG, Germany, has revealed its latest measuring innovation with the launch of the 3-axis lump detector for transparent products, branded Lump 2000 T. This follows on from the successful measuring performance of the 2- and 3-axis lump detectors used already during hose and tube production. The Lump 2000 T offers an additional future-oriented technology for the detection

readings at the fault detection. As there are no moving parts included in this technology there is also no need for calibration or maintenance.

of lumps and neckdowns in transparent materials, in particular for the production of medical tubes. The gauge heads are available for product diameters from 0.25mm to 10mm together with 0.5mm to 35mm. The heart of the new lump and neckdown detector is

the technically advanced double sensor technology. By means of light sources in combination with light sensors the Lump 2000 T detects (in 3 planes) the quantity, type, height, depth and length of the fault. The system defines punctual non-conformities in the product surface – even at production line speeds of up to 3,000m/min. The result of this technology is that even the smallest lumps and neckdowns of 0.01mm are detected and analysed by the Lump 2000 T with constantly high probability. Under difficult conditions such as extreme vibration the lump detector ensures reliable
