UltraFlex using induction to preheat steel forms to 1742°F/950°C within less than 5 seconds

The efficient and fast usage of induction heaters for preheating steel shovel molds has recently been demonstrated by UltraFlex Power Technologies.

The efficient usage of induction heaters for preheating steel shovel molds has recently been demonstrated by UltraFlex Power Technologies. Being a leading manufacturer of advanced induction heater solutions, the company is frequently showcasing the high efficiency of induction heating compared to traditional heating methods, for a rich variety of industrial applications.

In this demo case, a potential customer from the Dies and Molds industry was looking to replace their current gas furnace-based preheating method with induction heating, to achieve faster heat cycles, repeatability and a uniform heating temperature. The customer was manufacturing steel shovels and the process required to preheat metal billets to a target temperature of 1742°F/950°C, before they were further processed for bending and shaping. The target temperature had to be reached within less than 5 seconds.

For this heating process UltraFlex engineers recommended the use of an Ultraflex SmartPower™ system. UltraFlex SmartPower™ Compac are a breakthrough innovation in induction heating. The latest SiC transistor technology and proprietary digital control algorithms they use ensure optimal performance and maximum efficiency in a wide frequency range.

UltraFlex designed a custom induction coil for this heating process, so multiple shovel molds could be preheated at the same time and the productivity largely increased. With SmartPower™ turned on, it took less than 5 seconds for all steel molds to reach the target temperature of 1742°F/950°C! The customer had all target parameters met, but also achieved great thermal efficiency, thus substantially cutting down the energy consumed for the heating process. The heating times were decreased, and all heated items achieved uniform temperature.

If used on the production line, this induction heating process would ensure increased productivity and high-quality, repeatable results, independent of the operator's skills. This would also be a safe process - both for the operator and the environment - with no smoke, waste heat, and noxious emissions.

Innovative SWIR camera for UAV based spectral remote sensing

Allied Vision's compact and light weight Alvium SWIR (short wave infrared) cameras are the ideal choice to build cost-effective OEM systems used in embedded and machine vision applications. The cameras support a spectral range from 400 nm to 1700 nm at high quantum efficiencies. This allows to capture images in both the visible and SWIR spectra with a single camera and enables users to reduce overall system costs! Equipped with Sony's IMX990 and IMX991 SenSWIR InGaAs sensors, Alvium SWIR cameras deliver high image quality and frame rates. This makes them well suited for drones or handheld devices used in various industries such as, agriculture, mining, solar cell inspection or medical.
