In accordance with Ambrell, a cap to container seal is created using a laminated disc composed of a wax layer, aluminum layer plus a polyethylene (PE) layer. The aluminum layer acts as a susceptor, induction heating equipment to about 125 to 150 degrees C within the electromagnetic field created 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 in this high-speed, low energy consuming automated process.
Sealing caps on food containers and medicines are just about overlooked, but picture the safety and health dangers, along with the nasty molds, consumers can be at the mercy of if these caps weren’t properly sealed. The most extended induction application in this particular marketplace is the top-speed hermetic sealing in tamperproof packages, cap sealing and aseptic packaging. This system guarantees the integrity from the seal, plus the preservation of the product for longer amounts of time.
One of the leading benefits associated with induction heating is its energy efficiency. “Reduced energy usage inside the manufacturing process is really a win-win for building a competitive advantage,” says Mark Davis, Inside Sales Manager of Eldec Induction LLC. “Being enviromentally friendly in manufacturing is over a philosophy, a technique, or possibly a responsibility. It merely makes good ‘cents’ to minimize and conserve. Induction hardening or heating releases less internal residual stresses on account of the best possible energy input – measured in kilowatt seconds – and, therefore, just a small fraction when compared to the total mass that has got to be quenched during the final heat treatment. The best possible energy input and resulting reduced energy consumption translates right into improved environmental benefits.”
Induction heating is an environmentally friendly substitute for induction brass melting furnace, for example 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 dangers linked to the induction way 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” shall be linked to the equipment and also be 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.
Additionally, a nameplate should be affixed for the heating equipment, giving the manufacturer’s name, model identification along with the following input data: line volts, frequency, quantity 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 achieved with advice from suppliers who uses induction heating procedures 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 needs to be found in facilities to warn workers concerning the dangers of utilizing induction heating on power supplies and coils that utilize high voltage. Another recommendation is the application of personal protective equipment (PPE) linked to working together with induction brazing system. All equipment should utilize light guards or similar protective devices to prevent both exposure to the coil and moving mechanical assemblies that may harm the operator during automatic operations.
