Thermofoil™ Solutions for Heating Industry-leading heater technology Flexible Thermofoil™ Heaters Thermofoil™ heaters are thin, flexible components consisting of an etched-foil resistive heating element laminated between layers of flexible insulation. Since their introduction by Minco over 55 years ago, Thermofoil heaters have demonstrated significant advantages over conventional electric heaters. Precise heating Thermofoil heaters put heat where you need it. You simply apply them to the surface of the part to be heated. The thin construction provides close thermal coupling between the...

Custom Design Options Heater designs to perfectly fit your application Methods to derive the profiling pattern include: Minco’s Unmatched Design Options Experimentation: Lay out a pattern with standard heaters and vary the power levels until temperature reaches the desired uniformity. Or, Minco can provide a custom heater with separately powered zones for prototyping. Minco will then reproduce the successful profile with a single element. Finite Element Analysis (FEA): Although more expensive, FEA modeling of thermal systems can reduce the number of trials required to design a profiled...

Custom Design Options Value-added assemblies and complete thermal solutions. Overview Clamped mica heaters For best heater performance and reduced installation costs, consider Minco’s capabilities in mounting heaters to make complete thermal subassemblies. You can furnish the heat sinks or we can fabricate them to your specifications. Either way, you get a guaranteed bond, superior reliability, and the benefits of Minco’s experience with advanced adhesives and lamination equipment. In many cases we can affix the heater to the mating part in the same step used to bond its layers together....

Custom_Design_OptionsIntegrating sensors and thermal cut-outs Temperature sensors Integrating sensors into heaters simplifies your assembly operations by providing a gradient-free system with excellent temperature control. The sensor sits in a window of the heating element. It reacts to temperature changes in the component beneath the heater, yet remains close to the heating element itself. This tight coupling of heater, sensor, and heat sink can greatly improve heating control and accuracy. Sensors can be electrically connected via leadwires or flex circuitry. Surface Mount RTDs and...

Installing_a_Thermofoil_HeaterChoose the best method for your application Versatile Thermofoil heaters allow a variety of mounting methods. Proper installation is crucial to heater performance. The heater must be in intimate contact with the surface beneath, as any gaps can block heat transfer and cause a hot spot resulting in premature heater failure. Pressure-sensitive adhesive (PSA) Liquid adhesives require more care in application than PSA, but generally provide higher temperature/wattage performance.
