Palmer Foundry, the leader in vacuum tight and dimensionally stable aluminum castings, announces the launch of a new alloy, HyDuct5.
The foundry engineering that goes into a high quality casting even before the pattern is built leverages collective knowledge base over a wide array of products and markets…
Often times, a hole, boss or other feature must be located in a casting at a specific, (toleranced) position. The position requirements may be to ensure that the casting will assemble properly with other components, or to make sure that there is enough material on the feature to be removed during machining.

A profile tolerance can control the size, location, orientation and form of a feature. It typically defines a uniform boundary around the feature in which all elements of the feature must lie.
Palmer Foundry’s specialization in the vacuum chamber market started in the early 1980s. We had been working extensively to refine our process to meet the stringent vacuum and metal quality requirements. Our big break into this sector was with a “start-up” company that was willing to take a chance on this “new” technology for making vacuum chambers.
Find out how Palmer Foundry replaced welded and brazed aluminum assembly with a machined and polished VaPore® casting with a per part savings of $3,278.
A few years back we partnered with someone who was doing a Master’s Thesis on Vacuum performance under various scenarios. The information and charts in this article highlights the vacuum performance of a chamber cast at Palmer Foundry.
The biggest difference between casting tolerances, and billet tolerances is that casting tolerances are based on the size of the part, and where the feature is located. The aluminum association has published standards for sand castings.
