Product Description

Title goes here.

THE MOST IMPORTANT PROCEDURAL STEPS ARE EXPLAINED BELOW:
1. Source Material for the Pattern
This initial stage is pivotal for achieving excellence in lost foam casting. Selecting the right material is paramount to meet casting specifications. For aluminum die castings, the preferred choice is expandable polystyrene enriched with pentane, which acts as a highly efficient blowing agent. agent. Conversely, for crafting cast iron and steel components, a sophisticated copolymer blend of EPS and EPMMA is employed.

2. Pre-expansion
The expansion of polystyrene is notably efficient due to the presence of pentane, serving as a dynamic blowing agent. Displayed below is a bead that has been expertly pre-expanded using a fluidity bed dryer.
3. Molding
To fabricate the precise pattern section, pre-expanded EPS beads are expertly propelled through a fill gun into a permanent metallic mold using compressed air. Once inside, these beads seamlessly bond under heat to form the desired pattern geometry. Please refer to the detailed molding process outlined below.
4. Pattern Section Assembly and Mounting
Intricate pattern geometries are skillfully divided into simpler sections. Post foaming and drying, these sections are assembled to create a complete pattern, then mounted on a gating system to form a cohesive cluster.
5. Coating of the Clusters
The meticulously assembled clusters are subjected to a coating process, where they are immersed in a water-based refractory coating achieving an ideal thickness of roughly 2mm.
6. Mold Filling
The coated cluster is carefully placed in a flask, after which quartz sand is filled via a sand raining feeder. The sand is vibrationally compacted to ensure the cluster is completely embedded, leaving only the sprue visible.
7. Casting
A down sprue is precisely aligned over the EPS sprue. Molten metal is adeptly poured into this down sprue, seamlessly flowing into the foam pattern's gating system. As the molten metal progresses, it decomposes the EPS cluster, resulting in the mold cavity being filled with remarkable detail. Please review the comprehensive decomposition process outlined below.
8. Demolding
Following the solidification of molten metal, the casting emerges in its intended form. The castings are then advanced to the subsequent stage for meticulous cleaning.
9. Sand Processing DepartmentAfter demolding, the sand that has been utilized is efficiently transported to the processing system, where it undergoes recycling and preparation for reuse.
