In the field of temperature control equipment and mica products, NBRAM has always been highly regarded for its excellent technology and innovation capabilities.
Resistance wire tolerance is set before winding: trace elements melt-controlled to 0.01%, diameter drawn within 1% on diamond dies, elongation 15-25%, resistance read at several points per spool.
Inside our X-shaped aluminum heating tube line: extruded 6063/6061 profiles with four equal arms, CNC wire grooves held to 0.05 mm, hydrostatic compaction and an infrared check on all four faces.
Inside our silicone resin bonded mica tape line: how the binder stays supple after cure, why coating uniformity and a slow oven ramp decide flexibility, and what each batch is tested for.
NBRAM thermocouple ceramic insulation beads: 2-12 mm OD, 0.5-6.0 mm bores held to 0.02 mm, 99.5% alumina, 8 kV/mm at 1000°C, dielectric tested at 1000 V AC on every batch.
NBRAM thermal protectors cover 1A to 25A at 250V AC and 50-150°C with ±3°C standard accuracy. What the setpoint is measured on, how tolerance and reset time shape selection.
