Application of Cartridge Heater in Welding Unit of Strapping Machine
Fast Heat-Up | Precise Temperature Control | Compact Size | Long Service Life
The cartridge heater is a critical component in the welding unit of an automatic or semi-automatic strapping machine. Designed to deliver consistent and rapid heating, it ensures strong and uniform welds on PP, PET, or other plastic straps.
Its compact cylindrical design allows it to be embedded directly into the welding head, maximizing heat transfer efficiency and minimizing energy loss.
Advantages & Unique Features
Rapid Heating Response
Nichrome resistance wire enables fast temperature rise, reducing welding time.
Precise Temperature Control
Optional built-in thermocouple (J or K type) for accurate feedback and real-time control.
Compact & Durable Design
Stainless steel sheath with high-density MgO insulation, optimized for embedded applications.
Custom Fit for Welding Heads
Custom diameters and lengths ensure seamless integration into various strapping machine brands.
High Insulation Resistance
Prevents short circuits and ensures safe, continuous operation even in high-humidity environments.
Long Service Life
Designed for repeated heat cycles and continuous use in industrial packaging environments.
