Silica filtration mesh is highly effective material for cleaning of
melts of ferrous and non-ferrous metals while pouring them into the
The filter of necessary size is cut and installed into the gating
system or directly under the pouring gate between the bottom and
top moulding boxes. Usage of silica mesh filters allows to reduce
1, 5 - 2 times casting defects, to improve the metal structure, to
increase its physical-mechanical and technological properties.
Pre-shrunk silica meshes are subjected to additional thermal
treatment which allows to have minimum shrinkage while using of the
mesh and keep shape. Silica meshes can be treated with special
coatings which provides necessary stiffness of the filter.
The peculiarity of filters made of silica mesh - efficiency of
filtration of all traditional metals and and melts (aluminium,
magnesium and others), different types of cast iron and
