Product Description

Introducing Our Detailed Guide to Successful Lost Foam Casting.

THE MOST IMPORTANT PROCEDURAL STEPS ARE EXPLAINED BELOW:
1. Source Material for the Pattern
This stage is pivotal for exceptional lost foam casting success. Select materials tailored to casting needs. For aluminum die castings, we utilize expandable polystyrene with pentane, a superb blowing agent. In contrast, for cast iron and steel parts, a specialized copolymer of EPS and EPMMA is employed.

2. Pre-expansion
Thanks to the pentane blowing agent, polystyrene expands efficiently. Discover below a bead pre-expanded using a fluidity bed dryer.
3. Molding
For crafting the actual pattern section, pre-expanded EPS beads are directed through a fill gun into a permanent metallic mold using compressed air. In the mold, the beads bond during heating, forming the desired pattern geometry. Explore the molding process detailed below.
4. Pattern Section Assembly and Mounting
Complex geometric patterns are divided into manageable sections. After foaming and drying, these sections are assembled into a complete pattern and mounted on a gating system to form a cluster.
5. Coating of the Clusters
The assembled clusters undergo a coating process, where they are immersed in a water-based refractory coating to achieve an approximate 2mm thickness.
6. Mold Filling
The coated cluster is placed into a flask, and quartz sand is added using a sand raining feeder. Vibration compacts the sand until the cluster is fully encapsulated, with only the sprue remaining visible.
7. Casting
A down sprue aligns over the EPS sprue. Molten metal is introduced into this downsprue, traversing the foam pattern's gating system. The molten metal decomposes the EPS cluster, filling the mold cavity with stunning detail. Examine the decomposition process below.
8. Demolding
Upon solidification of the molten metal, the casting is complete. The castings advance to the next phase for further cleaning.
9. Sand Processing DepartmentFollowing demolding, the used sand is conveyed to the processing system for efficient recycling and reuse.
