UltraFlex preheating stainless steel cylinder using induction heating, achieving huge efficiencies compared to oven heating

A demonstration set up by UltraFlex for a company manufacturing water jet cutting equipment proved the huge efficiency of induction preheating compared to traditional, oven-based preheating.

In a recent customer-requested demonstration, UltraFlex proved the huge efficiency of induction preheating compared to traditional, oven-based preheating. UltraFlex - a leading manufacturer of advanced, digitally-controlled induction heaters - is frequently setting up induction heating demos using custom scenarios proposed by potential customers.


This demonstration was set up for a company manufacturing water jet cutting equipment who was looking to optimize one of their manufacturing processes. In the process, a stainless steel cylinder having 3.0" OD (76.5mm), 1.125" ID (28.5mm) and 6.8" (172.72mm) length had to be preheated, so the inner surface wall could be coated and cured with proprietary coating. The target temperature for the inside wall had to be 250 °F (121 °C), while the outside surface temperature would not have to exceed 400 °F (204°C).

By far, the customer had been using traditional, oven-based preheating, using batches of cylinders. The process, however, took 6-8 hours per batch and the customer was looking to cut down the time and costs using induction heating.

UltraFlex application engineers considered the UltraFlex induction heater from the UltraHeat W series as most appropriate for this heating scenario. UltraHeat W is an advanced, cost-effective 5-15 kW induction heater utilizing the latest switching power supply technology. It has easily adaptable temperature and power settings, which was important for this heating case.

At 10 kW of power supplied, it took 30 seconds for the surface temperature to reach 400 °F. The induction power supply was then switched off and conductivity left to transfer heat to the inside surface of the cylinder, until it reached 250 °F.

It took mere 55 seconds for the entire heating process to complete, with all target temperatures met. The customer was convinced that he could successfully replace oven heating with induction heating, achieving huge savings in both time and costs and increasing productivity on the line. Which is more, he could achieve a process which was easy to control and would have consistent results, with no dependability on the operator skills. Finally, thanks to the lack of open flame, induction heating would be a safe and green operation, with no smoke, waste heat, and noxious emissions.

BitFlow Introduces 6th Generation Camera Link Frame Grabber: The Axion

BitFlow has offered a Camera Link frame grabbers for almost 15 years. This latest offering, our 6th generation combines the power of CoaXPress with the requirements of Camera Link 2.0. Enabling a single or two camera system to operate at up to 850 MB/S per camera, the Axion-CL family is the best choice for CL frame grabber. Like the Cyton-CXP frame grabber, the Axion-CL leverages features such as the new StreamSync system, a highly optimized DMA engine, and expanded I/O capabilities that provide unprecedented flexibility in routing. There are two options available; Axion 1xE & Axion 2xE. The Axion 1xE is compatible with one base, medium, full or 80-bit camera offering PoCL, Power over Camera Link, on both connectors. The Axion 2xE is compatible with two base, medium, full or 80-bit cameras offering PoCL on both connectors for both cameras. The Axion-CL is a culmination of the continuous improvements and updates BitFlow has made to Camera Link frame grabbers.
