Heller VCO 755 In-line, Continuous Cure, Vertical Format Mini Curing Oven

Increase productivity, improve quality, reduce costs… with vertical format curing solutions from Heller.

In-line, vertical automation of the epoxy cure process produces immediate, significant benefits in three areas:

  • In-line automation increases productivity by eliminating the labor needed to load and unload batch ovens.
  • It improves process consistency, and therefore quality, by reducing the time and temperature variations caused by the frequent opening of batch oven doors.
  • And, as floor allocation costs rise on all factory floors… and particularly in clean rooms… a vertical format oven requires as little as six feet of floorspace for cure cycles as long as four hours
