Pre-Evacuated Retort Furnace for Precision Resistors
Precision resistors must maintain accurate and stable resistance values over time, temperature changes and demanding operating conditions. Their heat treatment therefore requires close temperature control and uniformity throughout the working zone.
A pre-evacuated retort furnace removes unwanted oxygen before the process begins. Controlled inert-gas circulation and direct cooling can protect surface quality, shorten cycles and improve production consistency for resistor alloys.
