Product Description

THE MOST IMPORTANT PROCEDURAL STEPS ARE EXPLAINED BELOW:
1. Source Material for the Pattern
In the world of lost foam casting, the selection of the right source material is crucial. Depending on the specific casting material, different materials are chosen. For aluminum die castings, expandable polystyrene containing pentane serves as the blowing agent of choice. This choice ensures the ideal expansion and quality of the final product. agent. However, when producing cast iron and steel parts, a superior copolymer composed of EPS and EPMMA is selected to meet the rigorous standards and demands of these robust materials.

2. Pre-Expansion
The introduction of pentane as a blowing agent enables the polystyrene to expand. The beads undergo pre-expansion using a fluidized bed dryer, ensuring optimal quality and consistency for the next stage in production.
3. Molding
In this pivotal phase, pre-expanded EPS beads are expertly delivered into a metallic permanent mold via a fill gun using compressed air. Once inside, the beads bond through heat, forming the desired pattern geometry. Discover the intricate molding process detailed below.
4. Pattern Section Assembly and Mounting of the Patterns on a Gating System
Complex pattern geometries often require segmentation into simpler sections. Post-foaming and drying, these sections are meticulously assembled into a complete pattern. Subsequently, multiple patterns are strategically mounted onto a single gating system to form a unified cluster.
5. Coating of the Clusters
In this step, the assembled clusters are submerged into a water-based refractory coating, ensuring a uniform 2mm thickness. This layer serves as a protective shield during the casting process.
6. Mold Filling The coated cluster is carefully positioned within a flask. Quartz sand is then precisely added using a sand raining feeder and compacted via a vibration table. This ensures the cluster is entirely enveloped by the quartz sand, with only the sprue remaining visible to facilitate the next stages.
7. Casting
A strategically placed down sprue aligns with the EPS sprue. As molten metal is poured into the down sprue, it seamlessly flows into the gating system, decomposing the EPS cluster and perfectly filling the mold cavity with intricate precision. Explore the decomposition process outlined below for further insights.
8. Demolding
Once the molten metal solidifies, the castings emerge ready for further processing. The next step includes careful conveyance for subsequent cleaning and refinement, ensuring each casting achieves its highest potential.
9. Sand Processing Department
After demolding, attention shifts to the used sand. It is meticulously transported to the processing system where it undergoes recycling, ensuring sustainability and efficiency throughout the production cycle..
