Improving ductile iron casting yield
In this case study, Elkem faced a challenge together with the customer, a foundry that produces critical safety components for the automotive and agricultural sectors. Elkem worked on increasing productivity by adding an extra cavity on the pattern plate, saving the customer production time and costs.
Solving shrinkage issues in a heavy duty iron casting
In this case, a globaly leading manufacturer of ductile iron castings for crittical machinery parts experienced leakage in housing elements. They specialise in elevator traction machinery, with parts weighing up to 10 tonnes.
Avoiding micro porosity defects in iron castings
In this case, a leading grey and ductile iron foundry experienced some defects. They specialise in producing automotive, agricultural, earthmoving and engineering castings for the global market. Previously they worked with a competitor’s inoculants and nodularisers. They experienced issues with machining their cast products.
Reviewing alloy additions in the production of safety-critical castings
In this case, a leading producer of ductile iron high-speed railway tie plates, experienced challenges to meet the required safety standards, especially caused by issues around shrinkage control.
When approached by the foundry, Elkem conducted a full process audit. Key areas for improvement were quickly identified.
Improving casting yield to increase profitability
Elkem faced a challenge together with the customer in this case, to increase the casting yield by metallurgical means, to improve the process efficiency.
