Cartridge heater with swaged in leads
Hasteco offers properly designed and constructed cartridge heaters with swaged in leads that are capable of both high-temperature and high-watt-density operation. For cartridge heater with swaged-in leads, the connection between the leads and power pins is inside the heater. So that swaged cartridge heaters are ideal for applications in which there is a lot of movement.
- Swaged cartridge heaters are ideal for applications in which there is a lot of movement.
- Leads could be exposed to high temperature environment at 500℃.
- 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 swaged-in leads?
Cartridge heaters with swaged-in leads consist of a resistive wire heating element enclosed within a metal or ceramic cartridge, with the lead wires tightly fixed or embedded within the cartridge through a swaging process.
Advantages:
1. Robust and durable construction.
2. Excellent mechanical strength and stability.
3. Secure the electrical connection between the lead wires and the heating element.
4. Efficient heat transfer and uniform heating.
Disadvantages:
1. Difficult to replace lead wires if they become damaged.
2. Limited flexibility compared to external wiring options.
When to use the cartridge heater with swaged-in leads?
What are the types of cartridge heaters with swaged-in leads?
Flange cartridge heaters typically have their leads or wiring exiting from one end of the heater. But it has swaged-in leads depending on the specific design and manufacture of the heater.
These types of leads have terminal pins at their ends. These pins allow for easy and secure connection to electrical circuitry.
