Coatings for sand moulds and cores

The foundry industry encompasses many metal types and production processes, producing an array of cast components in a multitude of different sizes. To acknowledge this diversity, Foseco have developed a variety of coating ranges to ensure that product and process are optimised. Furthermore Foseco offer a wide range of equipment for the handling and application of refractory coatings. Through the use of carefully selected refractory fillers, Foseco coatings are designed to deposit the correct coating structure onto a given substrate, to ensure cast surface integrity and help in the reduction and elimination of a number of casting defects:

Metal penetration
Poor casting strip
Mould erosion
Gas defects
Metal / mould reactions
Sand expansion defects
Metallurgical defects
Scabbing defects

Foseco's production iron coatings are designed for high-production foundries, ensuring consistent application and superior casting quality.

Coatings for high production cores and moulds

Production iron foundries are highly automated, often with a large proportion of cored castings. The application of coating is normally via a dipping operation. The range of coatings is focussed on providing exceptional dipping characteristics, whilst ensuring internal surfaces are free from casting defects.

Foseco's brush-on coatings for sand moulds and cores are designed to enhance casting quality by providing a protective barrier that prevents metal penetration, mould erosion, and gas defects.

Coatings for jobbing cores and moulds

This sector is typified by the variety of size and shape of cast components, ranging from many tonnes to less than a kilo. The processing of such components in, typically, short runs requires flexible manufacturing techniques. This variety and flexibility is reflected within the coating product ranges on offer from Foseco.

$Foseco's Intelligent Coating Unit (ICU) is an automated system designed to enhance the application of refractory coatings in foundries.$

Equipment

Foseco offer a wide range of equipment for the handling and application of refractory coatings, ranging from containers and mixer units to spray equipment, flow coating units as well as automated coating dilution (ICU).

Foseco's ACTICOTE CG water-based coating for compacted graphite iron (CGI) castings is designed to reduce the formation of flake graphite within the casting surface.

Speciality coatings

A full range of specialist products is also available to cover specific applications, such as coatings for full mould and lost foam processes, coatings for spun pipes and rolls, metallurgical and electrostatic coatings and coatings for refractories.
