Case Study
Foundry industry – Veining problems with casted gearboxes
Topic
A midsized German foundry is casting gearboxes (GJL-200) for a well-respected player. This foundry has been continuously facing the same problem. Although they used an expensive anti veining additive (dosage level 5.2 %), the results had been still negative as partially veining and poor surface quality occured. During the foundry process, smoke was generated caused by incomplete incineration and phenolic in the additive. In spite of using an expensive additive, the cores had to be coated.
Our solution
Adding 1.7 % MIOX® as anti-veining additie leads to casted parts which are completely veining-free and show an excellent surface quality. MIOX® is a completely inorganic substrance and free of Phenolic.
Additionally cores need not to be coated any more and the binder content can be reduced from 0.7 % to 0.55 % which provides economic advantages and reduces the emissions.
