Single-Head Cartridge Heaters

Single-ended cartridge heaters press into a drilled bore to heat metal directly. Supplied in high, medium and low watt density, with threaded bosses, integral thermocouples, right-angle exits, corrosion-resistant sheaths and finned variants.

A cartridge heater is a single-ended swaged heater that drops into a drilled bore to heat a metal block — a die, mold, platen or hot-runner manifold. Life is decided almost entirely by bore fit and watt density: a loose bore traps an air gap that pushes sheath temperature up sharply, so high-density cartridges above roughly 30 W/cm² need a reamed H7 bore and a tight swage. Jianqiang supplies high, medium and low density builds with optional integral thermocouples.

Catalog dimensions are nominal. On any order the controlling dimensions are those on the drawing approved before production starts — and roughly half of what this plant ships is made to a customer drawing rather than to a catalog code.
