induction sealing glass

Induction sealing glass to enclose resistors with high frequency induction heating system Objective Provide a hermetic seal of glass enclosed resistor to a lead Material Resistor Kovar rings, 0.1 inch (0.254cm) diameter Glass tube slightly larger than 0.1 inch (0.254cm) diameter, 0.5 (1.27) inch length Metal lead Temperature 900 ºF (482) ºC Frequency 324 kHz Equipment • DW-UHF-6kW-III induction heating system, equipped with a remote workhead containing two (2) 1.5 μF capacitors (for a total of 0.75 μF). • An induction heating coil designed and developed specifically for this application. Process A three turn concentrator plate coil is used to heat the Kovar ring for 500 milliseconds. This causes the glass to melt and seal one side of the resistor. The resistor is then turned over and the process is repeated to seal the other side using a second Kovar ring. Results/Benefits Induction heating provides precise, consistent heat to very small parts resulting in repeatable, quality seals. By heating with medium frequency, arcing (which occurs at high frequencies) is avoided.

Induction Heating Sealing

Induction Heating Sealing With High Frequency Induction Heating Equipment Induction heating provides an elegant means of sealing aluminum covers on jars of food products. The Induction Heating Sealing packaging method assures tamper protection, safety, hygiene and product preservation. Induction heating of the aluminum film increases the temperature of the sealing product applied to the side of the cover in contact with the jar. This heating is combined with pressure applied to the cover for 0.5 to 1.5s. This process is applied to all shapes of containers and for a wide range of materials, including: glass, cardboard, and plastics (PE, PP, PVC…). In all cases there is no contact between the inductor and the cover. In addition to this advantage, there are several reasons why this new method is increasingly used: ■ The heat is generated in the cover itself as near to sealing surface as possible. The process is thus simplified and the problems associated with the overheating of resistor type sealing heads are avoided. ■ The induction heat sealing method can be used for circular, oval, square, rectangular or other shapes ■ The medium frequency generator is made using solid state components and has no parts subject to wear during the heat sealing process. We supply several types of Induction Heating Sealing systems:

■ One-step induction heat sealing. ■ Continuous induction heat sealing before encapsulation. ■ Static induction heat sealing before encapsulation.
