The Wattheat crimped-on leads cartridge heater element is a standard and widely used structure in cartridge heaters. It uses high-temperature fiberglass leads crimped to solid pins, while the spiral resistance wire is housed in a stainless-steel tube and insulated with high-purity MgO for excellent heat transfer and electrical insulation. The non-heated end is protected by a contraction tube to keep the coil centered and stable. This type of cartridge heater is commonly used in sealing machines, mold heating, 3D printers, and packaging equipment. Contact us for custom specifications.

Crimped-on leads cartridge heater elements use a mechanical crimping process to firmly attach external lead wires to the internal power pins at the cold end of the heater. This creates a strong, vibration-resistant termination that prevents lead pull-out—one of the most common failure points in high-motion equipment. Compared with simple open-lead exits, the crimped structure provides better mechanical durability and improved basic moisture resistance, making it ideal for applications exposed to vibration, bending, or repetitive movement.
Discover the advanced engineering and precision manufacturing that makes our cartridge heaters the industry standard for durability, performance, and reliability in demanding applications.
The crimping process secures the lead wires by mechanically compressing a metal sleeve around the pin-to-lead connection at the cold end of the heater. This creates a strong, vibration-resistant mechanical joint that prevents lead pull-out—a common failure point in high-movement environments. While not a fully moisture-sealed termination, the reinforced crimp provides improved durability and stable performance in demanding industrial applications.
This reinforced termination significantly enhances durability and sealing, creating a connection that withstands the most demanding industrial environments.
