As outlined by Ambrell, a cap to container seal is created through the help of a laminated disc made up of a wax layer, aluminum layer and a polyethylene (PE) layer. The aluminum layer acts as a susceptor, induction heating system to around 125 to 150 degrees C within the electromagnetic field manufactured by the induction coil. It then gets hotter the wax and PE layer sufficiently to make a hermetic seal between your cap and container. Heating time is under a second with this high-speed, low energy consuming automated process.
Sealing caps on food containers and medicines are basically taken for granted, but think about the health and safety dangers, plus the nasty molds, consumers can be at the mercy of if these caps weren’t properly sealed. The most extended induction application in this sector is the high-speed hermetic sealing in tamperproof packages, cap sealing and aseptic packaging. This method guarantees the integrity of the seal, plus the preservation in the product for prolonged intervals.
One of the major advantages of induction heating is its energy efficiency. “Reduced energy usage in the manufacturing process is really a win-win for building a competitive advantage,” says Mark Davis, Inside Sales Manager of Eldec Induction LLC. “Becoming enviromentally friendly in manufacturing is greater than a philosophy, a method, or a responsibility. It merely 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 when compared to total mass that has to be quenched during the final heat treatment. The cheapest possible energy input and resulting reduced energy consumption translates directly into improved environmental benefits.”
Induction heating is an eco friendly alternative to induction melting metals furnace, like blowtorches, oil baths, ovens and hot plates. These expensive methods produce smoke, fumes and oil waste, and are hazardous to personal safety and working environments.
But there are actually dangers linked to the induction way 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” shall 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 removed from compartments containing 150 volts, AC or DC.
Furthermore, a nameplate should be affixed towards the heating equipment, providing the manufacturer’s name, model identification and the following input data: line volts, frequency, amount of phases, maximum current, full load kilovolt-amperes (kVAs) and full load power factor. Additional details are permitted.
Incorporating best safety practices involving induction heating can be carried out with advice from suppliers who uses induction heating methods 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 utilized in facilities to warn workers regarding the dangers of dealing with induction heating on power supplies and coils that utilize high voltage. Another recommendation is the application of personal protective equipment (PPE) associated with dealing with induction brazing heater. All equipment should utilize light guards or similar protective devices to prevent both connection with the coil and moving mechanical assemblies that may harm the operator during automatic operations.
