Cartridge heater with crimped on leads
Cartridge heater with crimped on leads
If vibration and impact resistant is not required in application, and it only need low to medium watt density cartridge heaters, then Non-swaged cartridge heaters offers a cost effective alternative to Swaged cartridge heaters.
- If the temperature at the end of heater is extremely higher than maximum rated temperature of the lead wire, Leads could be externally conntected to power pins. Cartridge heater with crimped-on leads has a advantage that the unheated length at the lead end of the heater is at a minimum.
- Leads could be exposed to a maximum temperature of 260 degrees
- Use recommended maximum watt density range to avoid excessive watt densities which result in the internal overheating of the heater.
- When heater requirements demand excessive watt densities, contact Hasteco for recommendations. Special heaters can be designed for these applications.
- Thermal expansion and contraction due to cycling shortens heater life. We recommend reducing watt densities by 20% for those heaters subject to frequent cycling.
- Be sure the full heated length is in contact with the metal to avoid burn-out by operating in air. The use of Infrakote thermal paste is recommended.

What is the cartridge heater with crimped-on leads?
A cartridge heater with crimped-on leads refers to a type of cartridge heater where the lead wires are attached to the heating element using a crimping process. Crimping is a method of securely joining two pieces of metal by deforming one or both of them to hold the other. The deformity is called the crimp.
In the context of a cartridge heater, the leads are crimped onto the heating element, providing a secure connection. This is an important feature in applications where the heater may be subjected to movement, vibration, or other forces that could potentially damage a less secure connection.
Crimped-on leads can be found on many types of cartridge heaters, including those with flanges, threaded fittings, or other mounting hardware. The specific design and manufacture of the heater will determine whether crimped-on leads are used.
It’s important to note that while crimped-on leads can provide a secure connection, they may not be as robust as swaged-in leads, which are formed using a high-pressure bonding process. The choice between crimped-on leads and swaged-in leads will depend on the specific requirements of the application, including factors like the operating environment, expected lifespan, and budget.
When to use the cartridge heater with crimped-on leads?
Packaging Industry
These heaters can be used in heat-sealing equipment, shrink-wrapping machines, and other packaging machinery where moderate heat is needed, and the equipment may be subjected to regular movement or vibration.
Plastics Industry
In the plastics and injection molding industry, cartridge heaters are often used to heat molds or to keep plastic at the correct temperature during the molding process. The crimped-on leads can withstand the regular heating and cooling cycles typical of these applications.
Medical Equipment
In the healthcare sector, cartridge heaters can be used in medical devices and laboratory equipment. For example, they might be used to heat samples for analysis or to sterilize equipment.
Automotive Industry
Cartridge heaters are often used in the manufacturing processes for automotive parts. They can be used for applications like heating molds for plastic parts, pre-heating engines, or in manufacturing equipment where reliable, localized heating is needed.
Food and Beverage Industry
Cartridge heaters with crimped-on leads can be used in various food processing and service equipment, such as grills, ovens, deep fryers, and coffee makers, where they can provide reliable, localized heat.
