 Capabilities of Cast Aluminum Molding
The molding experts at Bremer Mfg. make the most of the attributes of aluminum, one of the few materials that can be cast by all of the processes used in metal casting. Bremer experts offer the insight experience and equipment to match the particular cost and quality requirements of a cast component…as well as the desires of the customer…with the best possible casting technology.
Aluminum Die Casting
Especially suited to production of large quantities of relatively small parts, maintaining close tolerances and producing good surface finishes.
Permanent Mold Aluminum Casting
(gravity die) casting is also used in high volume production, often with parts that are larger than typical die castings
Sand aluminum casting
commonly takes two forms, both of which fall into Bremer’s capability:
- Conventional sand casting, in which the mold is formed around a pattern by ramming sand, mixed with the proper bonding agent, onto the pattern.
- Evaporative pattern casting (EPC) is a sand casting process that uses an unbounded sand mold with an expendable polystyrene pattern placed inside of the mold
Shell Mold Casting
utilizes a shell of resin-bonded sand only 10 to 20 mm thick - much thinner than typical sand molds.
Plaster Casting
uses a permeable (aerated) or impermeable plaster for the mold. Plaster’s high insulating value allows castings with thin walls to be poured
Investment casting
employs plaster molds and expendable wax patterns, producing precision parts with minimal extra machining
Centrifugal Casting
forces metal into a mold using centrifugal force
Continuous Casting
is done in a short, bottomless, water-cooled metal mold.
