The application of Refractory Coatings to the surface of Moulds
and Cores is a practice believed to date to as early as 4500BC. Since
that time and in the case of James Durrans & Sons Limited from
1863, Foundrymen have used Refractory Coatings to improve the casting
surface cosmetics of Iron, Steel and Non-Ferrous Alloys and to reduce
the cleaning operations and associated costs. Durrans Coatings have
helped reduce or eliminate problematic casting defects such as Veining,
Burn-on and Metal Penetration.
As with all aspects of the Metal Cast Industry Mould and Core Coatings
have undergone significant technology transformations in recent years.
These market drivers include; |
 |
Global demand for
improved casting quality and surface finish |
|
Requirements that cast parts approach
'near net shape' |
|
Wide application viscosities to make
them user friendly |
|
Reduced preparation and application
time |
|
Total compliance with environmental
regulations |
|
| The ultimate objective is clear - reduce the total manufactured
cost of the finished product (casting), while improving quality and
environment. |
