Product Description

The Essential Procedural Steps Unveiled Below:
1. Sourcing Material for the Pattern
This critical stage is the bedrock of successful lost foam casting. Selecting the right material is paramount, dictated by specific casting requirements. For aluminum die castings, we choose expandable polystyrene infused with pentane, an exceptional blowing agent ensuring optimal performance. Alternatively, for cast iron and steel parts, we employ a specialized copolymer composed of EPS and EPMMA to meet the distinct demands of these robust materials.

2. Pre-expansion
Through the remarkable properties of pentane as a blowing agent, the polystyrene expands efficiently. Below, observe a bead pre-expanded to perfection using a fluidity bed dryer, showcasing the remarkable technology in action.
3. Molding
To create the actual pattern section, pre-expanded EPS beads are dynamically introduced into a permanent metallic mold via a fill gun powered by compressed air. Inside the mold, these beads bond seamlessly under heat to craft the desired pattern geometry. Explore the whole molding process meticulously outlined below.
4. Pattern Section Assembly and Mounting
Complex pattern geometries are ingeniously divided into simpler sections. Following foaming and precise drying, these segments are assembled into a coherent pattern, skillfully mounted on a gating system to form an impressive cluster.
5. Coating of the Clusters
The meticulously assembled clusters are enveloped in a water-based refractory coating, achieving a precise thickness of approximately 2mm, ensuring robust and reliable performance.
6. Mold Filling
The coated cluster is strategically placed within a flask, where quartz sand is methodically filled using a sand raining feeder. Vibrations compact the sand until the cluster is thoroughly embedded, leaving only the sprue prominently exposed for the subsequent casting phase.
7. Casting
A down sprue is carefully aligned atop the EPS sprue. Molten metal is expertly poured into this down sprue, gracefully flowing into the foam pattern's gating system. The molten metal effectively decomposes the EPS cluster, skillfully filling the mold cavity with intricate precision. Delve into the decomposition process detailed below.
8. Demolding
Following the solidification of molten metal, a fully formed casting emerges. These castings advance to the next pivotal step for meticulous cleaning and finalization.
9. Sand Processing DepartmentUpon demolding, the used sand is efficiently transported to the state-of-the-art processing system, ensuring seamless recycling and reuse.
