This robust construction also offers high dielectric strength and shock and vibration resistance required for many industrial applications. For high temperature applications, such as those above 1000 ° F, colorless deposits are recommended for maximum heat transfer and durability. To place a cartridge Mica Band heater in a low or medium temperature application (600 ° F or less), general purpose drills are generally suitable for hole drilling. The holes should be drilled and mocked instead of drilled with a general piece. With a tighter fit, the stove will work better and have a longer life expectancy.

For heavy cartridge heaters, there is a gate or insertion point on the device to be heated. An inch rule for adjustment is to make the hole diameter no more than 0.005 inches larger than the heating diameter. We offer a full range of cartridge heaters with high density watt density to meet your specific needs. The “Max K” cartridge heater is designed to meet increasingly demanding requirements. Our high density compaction process ensures maximum reliability under unfavorable operating conditions.

The split sheath design of the cartridge heaters allows the heater to expand to maximize heat transfer by increasing contact with the hole walls, meaning that the heater consumes less energy. Pattern heaters provide accurate and accurate heat that is concentrated enough to meet the needs of a wide range of production applications. The construction of a cartridge heater starts with a ceramic core with a resistance cable around it. The core and resistance cable are enclosed in a steel or stainless steel dielectric metal cover. Heat is transferred from the resistance cable to the sheath and the material to be heated.

3 “leading past the armor is standard. If necessary, specify longer leads. Specify the galvanized or stainless steel armor and the total length of the cartridge heater. Teflon leads and seals: Teflon® insulated lead cables with the final Teflon® seal on the cartridge heating envelope provide superior moisture and chemical resistance. This design requires at least a cold 1 “section at the outlet end of the heater. 12 “wires are standard.

Teflon and TGGT cables have a 480 ° F rating, while MGT cables can withstand up to 840 ° F. The heating coil is the actual resistance where the electric charge occurs. The most commonly used type of metal alloy for this purpose is a nickel chromium mixture, also known as Nichrome. The Nichrome cable wraps around a ceramic core and the number of coils per inch varies depending on the requested watt density.

Designed for easy installation, cartridge heaters become smaller than their nominal diameter. However, they can be found in various compact sizes in options with low or high watt density. Choose a low watt density cartridge heater for packaging, heat sealing, laminating, cooling and melting tanks or nozzles. High density cartridge heaters are used in plastic extruders, hot printing, medical equipment, food processing, hot channel molds and other plastic molding equipment. The use of square cartridge stoves attached to milled grooves on the tool surface has become particularly cost effective with the advent of modern CNC machining. Square heaters attached to cooled, closed grooves ensure optimal heat transfer to the application, while the heater can be easily removed for cleaning or maintaining the system.
