CASTING

OUR FOUNDRY

The fully licensed foundry utilise electric furnaces with power supplied by our own on-site 500kva 3 phases generator. This clean approach to melting metal achieves the 1280 degrees C required for AB2 in less than 30 minutes.

LOW EMISSIONS

The company takes a responsible attitude to environmental issues and closely controls and monitors these to a level that is only a small fraction of the EU emission limits.

SAND RECLAMATION

Added to this is our reclamation unit which recovers and re-uses nearly 80% of the sand needed which eases the burden on the world’s expensive and limited landfill sites.

CASTING ANALYSIS

Density modelling through digital software simulates the casting process ensuring the most appropriate runner and risers systems are being used. What’s known as the ‘draw’ of the metal as it cools can result in porosity (air holes) in the casting, which can weaken the product, and at the surface of the metal even affects performance. Our software enables our highly skilled foundry technicians to prove out their theories without the expenses of true life trial and error.

Flow modelling allows us to simulate the effects of how the molten metal flows into the mould. Unlike the un-scientific methods still favoured by many foundries, CJR  is committed to ensuring the very best results are achieved every time. The software gives us that otherwise unavailable insight into making sure the integrity of our castings isn’t compromised by an inefficient or uneven flow which could cause turbulence leading to unsound structural integrity.
