8% Annual Yield Loss from Oven Insulation Powdering? Yujia® VAP Delivers Long-Term Zero-Dust Contamination
A fully sealed SUS304 metal vacuum insulation panel engineered for precision coating and electronics baking at up to 800°C
Many industrial ovens and tunnel furnaces run continuous cycles of drying, baking, curing, tempering, preheating, shaping, and aging. After 3–5 years, rock wool or aluminum silicate wool loses structural integrity from long-term high-temperature exposure and airflow vibration — resulting in powdering and brittle cracking. Because the oven interior is a circulation system, these fibers enter the circulating air through gaps and become the “hidden culprit” contaminating products.
The cost impact:
Yield Loss: Even a 1-percentage-point drop in yield means several tons of defective products per day on a line producing hundreds of thousands of units
Rework Costs: Polishing, cleaning, and repainting drive continuous increases in labor and material expenses
Brand Risk: Defective deliveries put next-quarter orders at risk
This is a typical case of “saving on material costs but losing profit.”
