vulcanization systems
PVO and NIR pre-vulcanization ovens
Pre-vulcanization systems are suitable for curing the outer surface of the profile to stabilize its geometry before coming into contact with the vulcanization oven conveyor belt.
The pre-vulcanization temperature inside the oven reaches about 600°C in the PVO system and 950°C in the NIR system.

High-speed hot air ovens
The principle of operation of the system developed and implemented by Colmec is based on the circulation of forced hot ai at high speed inside two concentric chambers. The external chamber, where the hot air circulates at low speed, is called the preheating tunnel because the air in this area is preheated. The internal chamber, where the hot air circulates at high speed, is called the vulcanization tunnel, here the profile vulcanization takes place. The air temperature and the air speed are adjustable.
