As outlined by Ambrell, a cap to container seal is created through the help of a laminated disc comprised of a wax layer, aluminum layer as well as a polyethylene (PE) layer. The aluminum layer behaves as a susceptor, induction heating system to about 125 to 150 degrees C within the electromagnetic field made by the induction coil. It then gets hot the wax and PE layer sufficiently to generate a hermetic seal in between the cap and container. Heating time is less than a second in this particular high-speed, low energy consuming automated process.
Sealing caps on food containers and medications are basically taken for granted, but picture the safety and health dangers, as well as the nasty molds, consumers can be subjected to if these caps weren’t properly sealed. Probably the most extended induction application within this market is the high-speed hermetic sealing in tamperproof packages, cap sealing and aseptic packaging. This method guarantees the integrity of your seal, and also the preservation of the product for extended time periods.
One of the leading benefits of induction heating is its energy efficiency. “Reduced energy usage inside the manufacturing process is a win-win for making a competitive advantage,” says Mark Davis, Inside Sales Manager of Eldec Induction LLC. “Being enviromentally friendly in manufacturing is more than a philosophy, a method, or even a responsibility. It really makes good ‘cents’ to lessen and conserve. Induction hardening or heating releases less internal residual stresses on account of the cheapest possible energy input – measured in kilowatt seconds – and, therefore, just a small fraction compared to the total mass that has got to be quenched throughout the final heat treatment. The smallest possible energy input and resulting reduced energy consumption translates right into improved environmental benefits.”
Induction heating is an environmentally friendly substitute for induction melting metals furnace, like blowtorches, oil baths, ovens and hot plates. These expensive methods produce smoke, fumes and oil waste, and they are hazardous to personal safety and working environments.
But there are actually dangers related to the induction means of heating. Fortunately, the 2014 edition of your National Fire Protection Association’s NFPA 70: National Electric Code addresses these concerns with specific guidelines for warning labels, signs and equipment marking.
Warning labels or signs that read, “Danger – High Voltage – Keep Out” will be attached to the equipment and become plainly visible where persons might come in contact with energized parts when doors are opened or closed, or when panels are taken from compartments containing 150 volts, AC or DC.
Additionally, a nameplate has to be affixed for the heating equipment, supplying the manufacturer’s name, model identification as well as the following input data: line volts, frequency, amount of phases, maximum current, full load kilovolt-amperes (kVAs) and full load power factor. Additional data is permitted.
Incorporating best safety practices involving induction heating can be achieved with advice from suppliers who uses induction heating approaches for new product development, process dexjpky33 and troubleshooting. Consultants work primarily with operators and line forepersons who are accountable for day-to day-equipment operations. Best practices include using lockout devices when servicing equipment.
Signs and labels should be found in facilities to warn workers in regards to the perils of working together with induction heating on power supplies and coils that utilize high voltage. Another recommendation is the application of personal protective equipment (PPE) connected with working with induction brazing system. All equipment should utilize light guards or similar protective devices to avoid both contact with the coil and moving mechanical assemblies that could harm the operator during automatic operations.
