Product Description

THE MOST IMPORTANT PROCEDURAL STEPS ARE EXPLAINED BELOW:
1. Source Material for the Pattern
This stage is a cornerstone for achieving excellence in lost foam casting. Take meticulous care in selecting your materials based on specific casting requirements. For crafting aluminum die castings, we prefer expandable polystyrene that contains pentane as it acts as a superior blowing agent. In contrast, for more robust applications such as cast iron and steel parts, a copolymer blend of EPS and EPMMA is the material of choice.

2. Pre-expansion
Witness the remarkable expansion of polystyrene, driven by pentane, an outstanding blowing agent. Below is an example of a bead pre-expanded using an advanced fluidity bed dryer.
3. Molding
In sculpting the actual pattern section, pre-expanded EPS beads are expertly driven through a fill gun into a permanent metallic mold with the aid of compressed air. Within this mold, a fusion occurs during heating, creating the pattern geometry with precision. Discover the detailed molding process outlined below.
4. Pattern Section Assembly and Mounting
Complex pattern geometries are ingeniously broken down into simpler sections. Once foamed and dried, these sections are skillfully assembled into a complete pattern and mounted on a gating system to form a cohesive cluster.
5. Coating of the Clusters
The assembled clusters are expertly coated by dipping them into a water-based refractory solution, achieving a consistent layer approximately 2mm thick.
6. Mold Filling
The precisely coated cluster is positioned within a flask. Quartz sand is meticulously filled using a sand raining feeder, with vibration ensuring the sand compacts perfectly until the cluster is fully embedded, leaving only the sprue exposed.
7. Casting
A down sprue is strategically aligned over the EPS sprue, allowing molten metal to be poured seamlessly into this channel. As it flows into the foam pattern's gating system, the molten metal effectively decomposes the EPS cluster, filling the mold cavity with intricate detail. Delve into the decomposition process described below.
8. Demolding
With the solidification of molten metal, the casting is formed to perfection. The castings are then prepared to move to the next stage for comprehensive cleaning.
9. Sand Processing DepartmentAfter demolding, the used sand is transported to our state-of-the-art processing system, ensuring efficient recycling and reuse.
