An aerospace component manufacturer running vacuum brazing furnaces identified inconsistent braze joint quality traced back to uneven hot-zone temperature distribution.
The Challenge
Single-layer radiation shielding was allowing heat loss variation across the furnace chamber, leading to temperature gradients during critical braze cycles.
The Solution
Upgrading to multi-layer molybdenum radiation shielding improved heat retention uniformity across the hot zone.
The Result
The manufacturer reported improved braze joint consistency and a measurable reduction in process-related rework.
