Additive manufacturingprocess realized MAN cylinder head

A cylinder head weighing several tonnes was produced at MAN B&W Diesel AG in Augsburg in record time, confirming the usefulness of the newest mold production technologies.

A company presentation by MAN B&W Diesel AG states as follows: “Diesel engines consist of 70% to 80% cast components, therefore our foundry is mainly concerned with the production of these components at the required quality and market-appropriate prices.” MAN B&W Diesel AG Augsburg is measuring its performance by this requirement as part of its daily operations. But is it also possible to produce a large diesel cylinder head in two weeks?

Challenge: Very large model with many undercuts

In contrast to a conventional mold structure, which consists of a top and bottom box as well as 19 cores, seven of which featuring different geometries, the mold was merely divided in half. The two halves of the mold contained the gating system, feeder heads and the downsprue. To ensure that chills could continue to be placed on the combustion space side, the front cover was separated from the mold and implemented in a conventional manner using core boxes.
