Product Description

THE MOST IMPORTANT PROCEDURAL STEPS ARE EXPLAINED BELOW:
1. Source Material for the Pattern
This initial stage is pivotal for the triumphant execution of lost foam casting. Carefully select the material in accordance with the casting's specific requirements. For aluminum die castings, we choose expandable polystyrene imbued with pentane, serving as a highly efficient blowing agent. agent. Conversely, for cast iron and steel parts, we employ a copolymer blend of EPS and EPMMA to achieve optimal results.

2. Pre-expansion
The polystyrene undergoes a seamless expansion process owing to the pentane serving as an effective blowing agent. In the following section, observe a bead pre-expanded using a fluidity bed dryer, showcasing its readiness for the next stage.
3. Molding
To produce the designated pattern section, pre-expanded EPS beads are expertly channeled through a fill gun into a permanent metallic mold with the aid of compressed air. Inside the mold, these beads meticulously bond under heat, forging the precise pattern geometry required. Discover more about the molding process detailed below.
4. Pattern Section Assembly and Mounting
Complex pattern geometries are intelligently divided into manageable sections. After undergoing foaming and drying, these sections are meticulously assembled to form an entire pattern and are then mounted on a gating system, creating a well-structured cluster.
5. Coating of the Clusters
The completed clusters are subjected to a rigorous coating process, where they are immersed in a water-based refractory coating to achieve a uniform thickness of approximately 2mm, ensuring enhanced durability and performance.
6. Mold Filling
The coated cluster finds its place within a flask, while quartz sand is meticulously filled using a sand raining feeder. Through vibration, the sand compacts flawlessly, embedding the cluster entirely with only the sprue left visible.
7. Casting
A strategically placed down sprue aligns over the EPS sprue. Molten metal is expertly poured into the downsprue, navigating through the foam pattern's gating system. The molten metal systematically decomposes the EPS cluster, intricately filling the mold cavity with precision. Examine the detailed decomposition process outlined below.
8. Demolding
Upon the solidification of the molten metal, the casting takes shape, ready for the subsequent stage of comprehensive cleaning and refinement.
9. Sand Processing DepartmentFollowing demolding, the used sand is efficiently transported to the processing system, setting the stage for recycling and reuse, thereby promoting sustainability and cost-efficiency.
