Metal Casting Solutions

Our industrial activity began in 1933 in the mineral foundry products sector, with the supply of coal and bentonite for the green molding process.

High-performance and innovative solutions guarantee our customers high performance of the systems and superior quality of the castings, essential in today’s competitive market.

We offer a wide range of bentonite and coal  for green molding, as well as silica sands and shell molding products. Our offer is completed by the laboratory and green moulding sand analysis service, in addition to continuous customer support which guarantees the availability of essential information and the resolution of production problems.

Green Sand Casting Process

A comprehensive range of bentonite products to meet all casting requirements, in addition to high-quality coal dust to guarantee excellent casting surface quality, silica sand to guarantee an optimal refractory skeleton, and starch additives for perfect moisture control.
All our green sand casting products guarantee excellent results in both the moulding phase and on the castings themselves, minimising the risk of defects.
 

Our premixed bentonite/coal dust/additives are formulated according to the individual needs of each customer, created to achieve the best yield depending on the specific type of facility and production.

Shell Moulding Process

The shell moulding process uses sand that is pre-coated with a thermosetting resin.

Pre-Coated Sand

The quality of the sand used, combined with a reliable and consistent process, ensures that our range of PRE-COATED SAND is compatible with all types of cores. Additionally, our specific formulas are created to handle situations where the core is particularly stressed and at risk of penetration or sintering.

Sand/Resin Casting Process

The sand/resin casting process requires high-quality, pure and consistent sand, which does not affect the action of the resin and/or catalyst. Available in a full range of grain sizes, foreign silica sand provides excellent results in terms of quality and consistency for all types of production.

Slag Removal

The slag removal process is carried out by dispersing natural granular perlite over molten cast iron. The coagulating and agglomerating effect of perlite allows slag to be easily removed from ladles and kilns.

Perlite

DESCORIL, our natural perlite, is available in two different grain sizes specifically selected to remove slag from ladles or furnaces, formulated for use on both cast iron and steel.

Auxiliary Casting Products

Lubricating powders and sealing strips to optimise the yield and quality of the various steps in the green sand casting process.

Graphite

Our GRAPHITE boasts impressive lubricating and refractory values: AMORPHOUS GRAPHITE, 65/70 C, is formulated to be dispersed in water with an appropriate binder in order to coat sand resin moulds, improving the refractory qualities of the mould and the surface finish of large castings; SILVER GRAPHITE 90 C is intended to be dusted on green sand moulds where the surface finish of the castings needs to be perfect.

Services and Technical Support

In foundry processes, technical support and close cooperation between supplier and customer are essential for maintaining the high quality standards of the Italian foundry sector in this difficult and competitive environment.

Services and Technical Support

The service department is made up of specialised technicians who carry out periodic visits and timely interventions, monitoring and preventing any casting issues and surface defects.
