Product Description

Title goes here.

THE MOST IMPORTANT PROCEDURAL STEPS ARE EXPLAINED BELOW:
1. Source Material for the Pattern
This stage is crucial for successful lost foam casting. Select the material based on the casting requirements. For aluminum die castings, we opt for expandable polystyrene containing pentane, which serves as an effective blowing agent. agent. In contrast, for cast iron and steel parts, a copolymer consisting of EPS and EPMMA is utilized.

2. Pre-expansion
The polystyrene expands efficiently due to the pentane acting as a blowing agent. Below, you will find a bead pre-expanded using a fluidity bed dryer.
3. Molding
For producing the actual pattern section, the pre-expanded EPS beads are propelled through a fill gun into a permanent metallic mold using compressed air. Within the mold, these beads bond during heating to form the desired pattern geometry. Please refer to the molding process outlined below.
4. Pattern Section Assembly and Mounting
Complex pattern geometries are segmented into simpler sections. After foaming and drying, these sections are assembled into a complete pattern and mounted on a gating system to create a cluster.
5. Coating of the Clusters
The assembled clusters undergo a coating process, where they are dipped into a water-based refractory coating, achieving a thickness of approximately 2mm.
6. Mold Filling
The coated cluster is positioned in a flask, and quartz sand is filled using a sand raining feeder. Vibration compacts the sand until the cluster is fully embedded, with only the sprue left exposed.
7. Casting
A down sprue is aligned over the EPS sprue. Molten metal is poured into this downsprue, flowing into the foam pattern's gating system. The molten metal decomposes the EPS cluster, filling the mold cavity in intricate detail. Please review the decomposition process below.
8. Demolding
Once the molten metal solidifies, the casting is formed. The castings progress to the next step for further cleaning.
9. Sand Processing DepartmentPost-demolding, the used sand is transported to the processing system for recycling and reuse.
