Import Cartridge Heater With Outside Wire — Buy in Bulk from Supplier in China

The cartridge heater with outside wire supplied by Shenzhen Annai Heating Element Co., Ltd. is an industrial‑grade heating element designed for direct insertion into molded or machined cavities. It is offered with tube diameters from 6 mm up to 23 mm and constructed from seamless stainless steel that provides reliable thermal conductivity. Multiple wattage configurations are available, and the heater incorporates outside wiring that simplifies connection and maintenance. Integrated over‑temperature protection helps prevent overheating during continuous operation.

The stainless‑steel sheath meets the standard corrosion‑resistant requirements for food‑processing and plastic‑moulding environments. While the supplier lists both standard and custom wattage options, typical cartridge heaters in this class operate between - 50 °C and 300 °C and are insulated with magnesium‑oxide powder to achieve high dielectric strength. Typical pressure tolerance reaches up to 10 bar, and dimensional tolerances are generally ±0.5 mm on the tube diameter. These characteristics align with common specifications for cartridge heaters used in batch ovens, extrusion dies and packaging equipment.

Primary users include manufacturers of plastics, food processing equipment and general industrial machinery that require precise, localized heat. Shenzhen Annai offers flexible minimum order quantities and ships under FOB or CIF incoterms, allowing buyers to tailor logistics to their supply chain. Prospective importers should confirm lead‑time, payment conditions and any required certifications directly with the supplier before placing an order.
