ESSENTIAL PROCEDURAL STEPS ILLUMINATED:
Step 1: Source Material for the Pattern
This foundational stage is pivotal for achieving excellence in lost foam casting. Material selection is dictated by the specific casting requirements. For aluminum die castings, we choose expandable polystyrene, infused with pentane, serving as a highly efficient blowing agent. Conversely, for crafting cast iron and steel components, a sophisticated copolymer blend of EPS and EPMMA is employed to achieve optimal results.

Step 2: Pre-expansion
Polystyrene undergoes rapid expansion, driven by the potent action of pentane as a blowing agent. Featured below is a bead that has been pre-expanded using state-of-the-art fluidity bed dryer technology.
Step 3: Molding
To create the definitive pattern section, pre-expanded EPS beads are expertly directed through a fill gun into a robust permanent metallic mold using high-pressure compressed air. Inside the mold, these beads undergo thermal bonding, crafting the exact geometry desired. Please examine the detailed molding process outlined below.
Step 4: Pattern Section Assembly and Mounting
Complex geometries are ingeniously divided into manageable sections. Post foaming and drying, these sections are meticulously assembled into a complete pattern, which is then affixed to a gating system, forming an intricate cluster.
Step 5: Coating of the Clusters
The assembled clusters are enveloped in a meticulous coating process. They are immersed in a specialized water-based refractory coating, achieving a uniform thickness of approximately 2mm.
Step 6: Mold Filling
The coated cluster is strategically placed within a flask, while quartz sand is precisely filled using an advanced sand raining feeder. Vibration ensures the sand compacts thoroughly until the cluster is entirely encased, save for the exposed sprue.
Step 7: Casting
An expertly aligned down sprue channels the molten metal into the EPS sprue. As molten metal is poured, it enters the foam pattern's gating system, dissolving the EPS cluster and intricately filling the mold cavity. Delve into the decomposition process below for further insights.
Step 8: Demolding
Upon solidification of the molten metal, a precise casting is realized. These castings then advance to subsequent stages for meticulous cleaning and final finishes.
Step 9: Sand Processing DepartmentFollowing demolding, the utilized sand is efficiently transported to a cutting-edge processing system, facilitating recycling and reuse, ensuring sustainable operations.
