\\n Frequently Asked Questions\\n <\\\/h2>\\n
\\n
\\n
\\u2753 Why can't my vacuum furnace reach the target vacuum level?<\\\/div>\\n
\\n Common causes: door seal leaks, roughing pump oil degradation, vacuum valve failure, or chamber contamination. The troubleshooting guide provides a systematic leak detection checklist and pump performance diagnostics to isolate the root cause quickly.\\n <\\\/div>\\n <\\\/div>\\n
\\n
\\u2753 What causes temperature uniformity issues in a vacuum furnace?<\\\/div>\\n
\\n Poor temperature uniformity is typically caused by: degraded heating elements (uneven resistance), damaged graphite felt insulation, thermocouple calibration drift, process gas flow disturbance, or hot zone contamination. The guide includes a step-by-step uniformity troubleshooting procedure.\\n <\\\/div>\\n <\\\/div>\\n
\\n
\\u2753 How to diagnose a heating element failure?<\\\/div>\\n
\\n Measure resistance phase-to-phase and phase-to-ground. An open circuit indicates a broken element; a ground fault indicates element sagging or insulation breakdown. Graphite elements develop hot spots visible through the viewport. Molybdenum elements show discoloration from oxidation. The guide includes resistance specification tables and replacement criteria.\\n <\\\/div>\\n <\\\/div>\\n
\\n
\\u2753 What to do when parts come out discolored or oxidized?<\\\/div>\\n
\\n Part discoloration usually indicates oxygen or moisture contamination in the chamber. Check: door seal integrity, backfill gas purity, cooling water leakage inside the chamber, and binder removal completeness. The guide provides a systematic root cause analysis for surface quality defects.\\n <\\\/div>\\n <\\\/div>\\n
\\n
