Far-Infrared Annealing Furnace

Engineering

The significant reduction in annealing time by effectively using the heat emissions from far-infrared heaters revolutionizes the annealing of resin molds.

Temperatures Used: R.T. + 15 to 350°C

* Specified heater value

Temperature Accuracy: ±3°C

* Standard product temperature

Cleanliness: Class 10,000 (Class 1,000-compatible)

Far-Infrared Annealing Furnace

Sample Processed Products

  • 「Automotive Parts」
    Electronic sensors
  • 「Electronic Parts」
    Electromagnetic switch
  • 「Precision Medical Instruments」
    Dialysis parts

Features

  • Significantly Shortened Processing Time
    Significantly shortened processing time by combining far-infrared heat emission with heat dispersed by air blasting.
    Conventional hot air batch furnace: 1-2 hours→Noritake Annealing Furnace: 3-5 minutes
  • Continuous Processing with Conveyor
    A compact continuous furnace is created by the shortened processing time. Therefore connection is possible with a molding machine to make one continuous process and increase production efficiency.
  • Better Quality
    Heat uniformly by combining a highly responsive far-infrared heater with a hot air dryer. Furthermore, continuous processing makes for reliably accurate dimensions.
    Dimension Accuracy:±5/100mm→±2/100mm
