In accordance with Ambrell, a cap to container seal is produced through the help of a laminated disc composed of a wax layer, aluminum layer along with a polyethylene (PE) layer. The aluminum layer acts as a susceptor, induction heating manufacturer 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 between the cap and container. Heating time is under a second within this high-speed, low energy consuming automated process.
Sealing caps on food containers and medications are just about neglected, but think of the health and safety dangers, along with the nasty molds, consumers would be at the mercy of if these caps weren’t properly sealed. By far 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 from the seal, as well as the preservation from the product for much longer time periods.
One of the major benefits associated with induction heating is its energy efficiency. “Reduced energy usage from the manufacturing process is actually a win-win for making a competitive advantage,” says Mark Davis, Inside Sales Manager of Eldec Induction LLC. “Becoming environmentally friendly in manufacturing is more than a philosophy, a strategy, or perhaps a responsibility. It really makes good ‘cents’ to lessen and conserve. Induction hardening or heating releases less internal residual stresses due to the cheapest possible energy input – measured in kilowatt seconds – and, therefore, simply a small fraction compared to the total mass that needs to be quenched during the final heat treatment. The best possible energy input and resulting reduced energy consumption translates directly into improved environmental benefits.”
Induction heating is an eco-friendly option to induction 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 linked to the induction approach to heating. Fortunately, the 2014 edition from 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 coupled to the equipment and be 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.
Moreover, a nameplate needs to be affixed for the heating equipment, offering 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 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 should be utilized in facilities to warn workers concerning the perils of utilizing induction heating on power supplies and coils that utilize high voltage. Another recommendation is the use of personal protective equipment (PPE) linked to working together with induction brazing heater. All equipment should utilize light guards or similar protective devices to stop both connection with the coil and moving mechanical assemblies which may harm the operator during automatic operations.
