Description
5mm Diameter miniature cartridge heater is made according to the actual needs of customers,the research and development, design and production is used in micro precision mold heating.It is made by imported raw materials, precision processing equipment, combined with our company's many years' research and development and design experience.
Over the years, it has been used by many R & D institutions, precision mold design enterprises, hot runner mold enterprises, medical equipment enterprises, and has solved the actual needs and design problems of many customers.
It has precise size and fine workmanship,the bottom of the pipe is soldered firmly. Gauge seamless stainless steel tube ,sealing imported materials and process.Electric wire is teflon wire imported from Germany glass fiber nickel core wire imported from Japan.
5mm Diameter miniature cartridge heater is a small heating element that is used to heat up small areas or components. It is often used in industrial applications, such as in machinery or equipment that require precise heating. The heater is shaped like a cartridge, with a cylindrical body and two wires extending from one end. It can be inserted into a hole or clamp in the component, and the electrical current passing through the wires heats up the cartridge.
It can be used to cover the full spectrum of cartridge heater applications. While a standard range of cartridge heaters is available, we design and manufacture cartridge heaters exclusively to our customers' requirements. It is important to choose the right building heater for your application.
The minimum diamter we can do is 2mm,the voltage can be 3V,5V,12V,24V,36V.
The Incoloy 800 material is designed to withstand temperatures up to 900°C, ensuring stability and durability in extremely hot environments.miniature design is easy for installation in compact spaces.
The seamless metal jacket on this cartridge heater element is made from a single piece of metal, providing excellent jacket integrity for high altitude and high stress applications. Deep drawing eliminates the risk of solder failure when equipment reliability is critical.
It provides localized and precise heat.
It is also important to consider the electrical termination of a cartridge in regard to the operating temperature. When 5mm diameter micro cartridge heater is used at relatively high temperatures, the electric terminals should either be different than the common high temperature lead wires or the cartridge should be designed in a manner that the temperature around the lead wires is maintained at a lower temperature than the temperature limit of the lead wire.
Concerning the cartridge lead wire,the following can be your reference:
1.Conventional high temperature wire: is our most common lead wire, it can withstand the temperature is 100-400℃.
2.Mica high temperature wire: used for air dry burning cartridge heater, the lead wire will also be exposed to high temperature, it can withstand the temperature is 500-600℃.
3.Pure nickel wire: It is also a very high temperature resistant lead wire, the temperature is used at 700 ° C.
4.Ceramic bead lead: when the temperature is relatively high, it can withstand 700-800℃.
5.Metal hose lead wire: often used in the case of lead friction.
6. PTFE wire: generally used when heating corrosive liquids, with a certain corrosion resistance.
Small Diameter, Miniature Cartridge Heaters Selection Guide
How much wattage is required?
What voltage will be used?
What is the heated length? What is the overall length?
How long are the heater leads or what is the lead length required?
What is the dimentions of the cartridge heater?
What is the ambient temperature the cartridge heater will see?
What is the maximum temperature required from the heater?
How quickly do you want to reach your operating temperature or set point in hour/minutes? What is the type and weight (in lbs.) of the material you want to heat? Special Modifications
Patented high-temperature design provides these advantages:
When energized, the patented split-sheath expands into contact with surrounding bore for maximum heat transfer, fast response.
When de-energized, the split-sheath contracts for easy, slide-out removal. Sunrods are guaranteed never to sieze in the bore.
Uninterruped hot zone and fully heated tip provides unmatched heat distribution without cold spots.
Slender continuous leads simplify wire management. High flexibility allows free motion when heating "floating" components.
The result is a miniature cartridge heater offering longer life, uniform temperatures, and easy installation in the smallest devices.
Application
Cartridge heaters are most frequently used for heating dies, platens, molds, and other metal parts by insertion into drilled holes. They can also be used in liquid immersion applications. Below are some examples of specific applications:
Heating gases and liquids
