Curing
Oven - A Boon For Industries
Curing
oven is a boon to the industries that helps in curing of the product,
which is the final step of the painting process. The curing oven
raises the temperature of the product mass and keeps it stable
for a long time. Before the product is made to enter the curing
oven, the product should be cleaned, dried, coated and rinsed.
Various
Applications Of The Curing Oven
Temperature and time are very important factors to consider while
you are curing the coated product. However, you should be careful
to avoid any danger. Apart from simple curing, the oven also serves
various other purposes.
Following are some of the applications of Curing oven:
• Core hardening
• Preheating
• Baking
• Aging
• Plastic curing
• Paint drying
• Epoxy curing
• Varnish baking
• Shrink packaging
Curing
Combination Oven
Curing oven is often used to cure powder coatings also. This powder
coating is easily done with another type of curing oven called
the combination oven -- oven that employ both infrared and convection
rays. This oven usually connects infrared and convection heating
zones together in series, that is, a zone of infrared followed
by a zone of convection.
Different
Types Of Curing Oven
There are three types of curing ovens basically used by the industries.
They are Vertical shock oven, Horizontal cure oven heated by infrared
and Horizontal cure oven heated by hot air.
Vertical
shock oven - With the help of this oven, it becomes very
easy and fast to process sponge extrusion as the change of the
length of the profile during the cure process does not affect
processing. The thickness and specific gravity of the product
is maintained.
Horizontal
cure oven heated by infrared - With the temperature ranging
from 250-300°C, this oven offers fast curing along with retaining
the perfect thickness of the product.
Horizontal
cure oven heated by hot air - The speed of hot air transfer
is very fast in this oven thereby leading to a rapid curing of
the products. The temperature can be raised to 290-320°C.
The people involved in the coating process should know the proper
temperature and time required for curing the products. However,
the curing processor should also know the other factors like product
window size, line speed, product weight/ conveyor weight and hanging
space needed for the products.
