According to Ambrell, a cap to container seal is made with the help of a laminated disc comprised of a wax layer, aluminum layer and a polyethylene (PE) layer. The aluminum layer provides a susceptor, induction heating units to around 125 to 150 degrees C inside the electromagnetic field created by the induction coil. It then heats up the wax and PE layer sufficiently to make a hermetic seal in between the cap and container. Heating time is under a second in this high-speed, low energy consuming automated process.
Sealing caps on food containers and medicines are basically taken for granted, but picture the safety and health dangers, and also the nasty molds, consumers could be subjected to if these caps weren’t properly sealed. One of the most extended induction application within this market is our prime-speed hermetic sealing in tamperproof packages, cap sealing and aseptic packaging. This system guarantees the integrity of the seal, and also the preservation of the product for much longer intervals.
One of the major benefits associated with induction heating is its energy efficiency. “Reduced energy usage from the manufacturing process is really a win-win for creating a competitive advantage,” says Mark Davis, Inside Sales Manager of Eldec Induction LLC. “Becoming environmentally 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 due to the smallest possible energy input – measured in kilowatt seconds – and, therefore, simply a small fraction when compared to the total mass that has to be quenched in the final heat treatment. The cheapest possible energy input and resulting reduced energy consumption translates right into improved environmental benefits.”
Induction heating is an eco-friendly alternative to induction aluminum melting furnace, including blowtorches, oil baths, ovens and hot plates. These expensive methods produce smoke, fumes and oil waste, and so are hazardous to personal safety and working environments.
But you can find dangers linked to the induction approach to 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” shall be coupled to the equipment and stay plainly visible where persons might come in touch with energized parts when doors are opened or closed, or when panels are removed from compartments containing 150 volts, AC or DC.
In addition, a nameplate needs to be affixed for the heating equipment, supplying the manufacturer’s name, model identification as well as the following input data: line volts, frequency, variety of phases, maximum current, full load kilovolt-amperes (kVAs) and full load power factor. Additional info 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 responsible for day-to day-equipment operations. Best practices include using lockout devices when servicing equipment.
Signs and labels needs to be used in facilities to warn workers in regards to the hazards of working with induction heating on power supplies and coils that utilize high voltage. Another recommendation is the usage of personal protective equipment (PPE) connected with utilizing induction brazing machine. All equipment should utilize light guards or similar protective devices to avoid both connection with the coil and moving mechanical assemblies that may harm the operator during automatic operations.
