Product Description

Title goes here.

THE MOST CRUCIAL PROCEDURAL STEPS ARE EXPLAINED BELOW:
1. Procuring Material for the Pattern
This phase forms the bedrock of successful lost foam casting. Carefully select material based on your specific casting requirements. For aluminum die castings, we leverage expandable polystyrene infused with pentane, a potent blowing agent. agent. Conversely, for cast iron and steel parts, a copolymer blend of EPS and EPMMA is employed.

2. Pre-expansion Process
The polystyrene expands optimally, thanks to pentane's role as a diligent blowing agent. Illustrated below is a bead pre-expanded utilizing a cutting-edge fluidity bed dryer.
3. Molding Sequence
To craft the actual pattern segment, pre-expanded EPS beads are injected through a fill gun into a robust permanent metallic mold using compressed air. Inside, these beads coalesce during heating, forming precise pattern geometry. Please explore the outlined molding process below.
4. Assembling and Mounting the Pattern Section
To tackle complex pattern geometries, these are divided into more manageable sections. Post-foaming and drying, sections are assembled into a cohesive pattern and mounted on a gating system to establish a cluster.
5. Cluster Coating Procedure
The assembled clusters undergo a meticulous coating process, where they are immersed in a water-based refractory coating, achieving a uniform thickness of about 2mm.
6. Mold Filling Process
The coated cluster is strategically positioned within a flask as quartz sand is meticulously filled via a sand raining feeder. Vibration compacts the sand, ensuring the cluster is entirely enveloped, save for the sprue that remains exposed.
7. Casting Phase
A down sprue is precisely aligned with the EPS sprue. As molten metal is poured into this downsprue, it flows seamlessly into the foam pattern's intricate gating system. The molten metal efficiently decomposes the EPS cluster, intricately filling the mold cavity. Please examine the decomposition process below.
8. Demolding Step
Once the molten metal solidifies, the casting takes shape and is ready to move to the subsequent stage for thorough cleaning.
9. Sand Processing DepartmentFollowing demolding, the utilized sand is conveyed to an advanced processing system where it undergoes recycling and preparation for reuse.
