In accordance with Ambrell, a cap to container seal is created with the aid of a laminated disc comprised of a wax layer, aluminum layer plus a polyethylene (PE) layer. The aluminum layer works as a susceptor, induction heating machine to about 125 to 150 degrees C within the electromagnetic field produced by the induction coil. It then gets hotter the wax and PE layer sufficiently to generate a hermetic seal between your cap and container. Heating time is less than a second in this high-speed, low energy consuming automated process.
Sealing caps on food containers and medications are virtually neglected, but think about the safety and health dangers, as well as the nasty molds, consumers can be at the mercy of if these caps weren’t properly sealed. One of the most extended induction application in this marketplace is the top-speed hermetic sealing in tamperproof packages, cap sealing and aseptic packaging. This method guarantees the integrity from the seal, along with the preservation of your product for much longer intervals.
One of the leading benefits of induction heating is its energy efficiency. “Reduced energy usage from the manufacturing process is a win-win for creating a competitive advantage,” says Mark Davis, Inside Sales Manager of Eldec Induction LLC. “Becoming environmentally friendly in manufacturing is greater 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 because of the lowest possible energy input – measured in kilowatt seconds – and, therefore, just a small fraction when compared to total mass that has got to be quenched in the final heat treatment. The lowest possible energy input and resulting reduced energy consumption translates straight into improved environmental benefits.”
Induction heating is an eco friendly alternative to induction brass 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 there are dangers associated with the induction method of heating. Fortunately, the 2014 edition in the 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 stay 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.
Furthermore, a nameplate must be affixed on the heating equipment, giving the manufacturer’s name, model identification as well as the following input data: line volts, frequency, number 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 techniques 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 employed in facilities to warn workers about the hazards of utilizing induction heating on power supplies and coils that utilize high voltage. Another recommendation is the usage of personal protective equipment (PPE) related to dealing with induction brazing machine. All equipment should utilize light guards or similar protective devices to stop both experience of the coil and moving mechanical assemblies that may harm the operator during automatic operations.
