Precision electronic instruments, laboratory constant temperature equipment and miniature mechanical parts require ultra-small diameter embedded heating components. Traditional heating tubes have large size, poor dimensional accuracy and unstable temperature control, unable to meet miniature precision heating requirements. Miniature internal wiring cartridge heaters adopt ultra-fine precision processing, realizing stable, uniform and safe heating in extremely narrow small-space environments.
Small-diameter internal wiring heaters cancel bulky terminal structures, adapting ultra-small mounting holes that ordinary tubes cannot enter. Integrated internal lead outgoing makes overall size more compact, matching miniature precision equipment internal layout perfectly. Coreless ultra-precision grinding controls diameter error at extremely low level, achieving precise gap fit with tiny instrument holes without damaging precision parts.
Uniform surface temperature ensures high-precision constant temperature control required by instruments. 25W/cm² reasonable surface load realizes fast and gentle temperature rise, no sudden temperature impact, protecting sensitive precision components. Small temperature drift maintains stable working temperature for a long time, ensuring accurate data detection and normal operation of laboratory and medical precision instruments.
High insulation safety performance adapts electronic precision circuits. Stable insulation resistance, low leakage current and reliable withstand voltage performance will not interfere with instrument signal transmission, nor cause circuit short circuit damage. High-temperature resistant leads remain soft and stable in narrow spaces, not easy to break or age under long-term continuous heating.
Sealed dustproof structure adapts clean precision instrument working environments. No exposed gaps avoid dust accumulation, ensuring long-term stable thermal performance. Material expansion matching prevents tube deformation and cracking under repeated temperature changes. Wide ambient temperature adaptation from -20℃ to 60℃ meets indoor laboratory constant temperature use requirements.
Long service life reduces frequent disassembly replacement of precision instruments, protecting assembly accuracy. Mini internal wiring heating tubes are widely used in medical testing equipment, optical instrument constant temperature, miniature mold heating and electronic component thermal processing. It fills the gap of high-quality small-space precision heating components in the industrial market.
