Product Description

Title goes here.

THE MOST IMPORTANT PROCEDURAL STEPS ARE EXPLAINED BELOW:
1. Source Material for the Pattern
In the realm of lost foam casting, choosing the right source material is paramount. Our material choice varies with the casting material. For aluminum die castings, we opt for expandable polystyrene infused with pentane as a blowing agent, ensuring optimal performance. agent. In contrast, for crafting robust cast iron and steel parts, we rely on a specialized copolymer composed of EPS and EPMMA for unmatched durability and efficiency.

2. Pre-expansion
Polystyrene, with its pentane component, becomes remarkably expandable. Below, we illustrate a bead pre-expanded using a fluidity bed dryer, setting the stage for the subsequent molding process.
3. Molding
The journey to crafting the perfect pattern begins here. Pre-expanded EPS beads are expertly propelled into a metallic permanent mold using compressed air via a fill gun. Within the mold, the beads bond seamlessly upon heating, achieving the precise pattern geometry. Explore the meticulous molding process below.
4. Pattern Section Assembly and Mounting on the Gating System
In the art of assembling complex pattern geometries, simplicity is key. Following foaming and drying, these segmented sections are meticulously combined into a complete pattern. Subsequently, multiple patterns are mounted on a singular gating system, forming a cohesive cluster.
5. Coating of the Clusters
With precision and care, the assembled clusters are immersed in a water-based refractory coating bath, achieving a uniform 2mm-thick coating that fortifies the cluster.
6. Mold Filling As the coated cluster finds its place in a flask, quartz sand cascades down through a sand raining feeder, compacted meticulously by a vibration table. At the end of this process, the cluster is cocooned within the quartz sand, leaving only the sprue exposed.
7. Casting
A down sprue is strategically positioned over the EPS sprue. Molten metal cascades through this conduit, entering the gating system of the foam pattern. The molten metal deftly decomposes the EPS cluster, filling the mold cavity with precision. Delve into the decomposition process shown below.
8. Demolding
Once the molten metal solidifies, the castings emerge in their final form, ready for the next phase. We transport them to the next stage for meticulous cleaning, ensuring pristine quality.
9. Sand Processing Department
In the aftermath of demolding, our commitment to sustainability shines. Used sand is conveyed to the processing system for essential recycling, preparing it for reuse..
