Design Variations

For applications on cylindrical parts or where the installation is temporary, eyelets with springs or snap fasteners are utilized to mount heaters. Spring fasteners allow for variations in circumference while providing close contact with the part to be heated. Many types of fasteners used for canvas or leather can be built into the sheath of the heaters.

• Eyelet
• Snap
• Spring
• Any other fasteners suitable for thin, flexible material

Lead types and exit locations are adaptable to application requirements. Perimeter exit (standard) or surface exit do not present design limitations.

• Silicone rubber
• Teflon®
• HPN heater cord (& molded plug if needed)
• Other

Silicone rubber can be bonded to metal parts to create complete thermal subassemblies. Since a perfect fit between heater and part is a vital factor in heater efficiency, customers normally supply metal parts so we can bond or vulcanize the heater to the part in our factory, and thus assure optimum contact. Temperature sensors or thermostats may be integrated into these heaters, along with provision for temperature controllers.

As part of the manufacturing process, the heater is vulcanized directly to your part. This produces a very strong void-free bond between heater and part, for the best possible heat transfer and extended heater life. When other methods of bonding have caused heater failure, factory vulcanizing can solve the problem. Also maximum watt densities can be utilized to reduce heater size, thereby lowering cost.

Hi-Heat offers 3-dimensional heaters, which can be designed and built to fit perfectly around the complex contours of your part. This results in efficient heating and lower heating costs because there are no “dead” areas. Our application specialists are happy to work with you to satisfy these complex design challenges.
