Manufacturing capabilities

Aluminum & bronze sand casting

A Baltimore nonferrous foundry casting A356, A357, C355, 319 and 535 Almag aluminum alloys, plus aluminum, silicon and manganese bronze. Conventional tooling and 3-D printed sand molds support your component geometry.

A connected process

01

Define

Review alloy, geometry, quantity and acceptance criteria.

02

Form

Produce pattern tooling or print sand molds and cores.

03

Cast & finish

Pour, clean, heat treat and machine as specified.

From molten metal to a finished casting

Metal is melted and poured into a mold made from bound sand. After cooling, the sand mold is broken away, and the gating and risers are removed for remelting. Our team grinds and cleans each casting before the next manufacturing stage.

Connected to the next process

In-house heat treatment, CNC machining and inspection keep casting connected to the requirements of the finished component. Blasting options include aluminum oxide, glass beads and shot blast.
