Air Set (No-Bake) Aluminum Casting & Molding
Bremer Manufacturing operates a large air set molding line, enabling production of much larger and heavier aluminum parts than can be produced on our green sand casting Hunter machines. Another type of aluminum sand casting, air set molding (also known as “no-bake” molding) uses chemically bonded sand to form high-strength molds needed to produce large, complicated shapes that many parts require. Parts can weigh up to 120 pounds and measure 60” inches in length utilizing this operation.
Internal passageways and undercuts on parts can be easily produced using cores made in the air set operation, using warm box cores made on the Redford machines, or purchased from an outside source.
High Output Aluminum Casting with Low Cost and Lead Times
Aluminum casting patterns for the air set molding line are typically made of wood and plastic, keeping pattern cost and lead time down. What’s more, multiple patterns of various part numbers may be run simultaneously on our molding loop, and multi-cavity patterns and core boxes can also be used to increase throughput for larger volume projects. Bremer’s air set pouring line includes three aluminum melt furnaces complete with an automatic mold shakeout station, which captures sand to be run through our reclamation system for reuse – lower costs even further.
