Product Description

Title goes here.

THE MOST IMPORTANT PROCEDURAL STEPS ARE EXPLAINED BELOW:
1. Source Material for the Pattern
Selecting the right source material is a cornerstone for flawless lost foam casting. For die castings in aluminum, we choose expandable polystyrene, infused with pentane, a remarkable blowing agent that ensures high-quality results. agent. Conversely, for crafting robust cast iron and steel components, a sophisticated copolymer blend of EPS and EPMMA is employed for superior performance.

2. Pre-expansion
In this phase, the polystyrene expands robustly, with pentane as the dynamic blowing agent. Here, a bead is pre-expanded using an advanced fluidity bed dryer, setting the stage for precision molding.
3. Molding
Creating the actual pattern section involves propelling pre-expanded EPS beads through a fill gun into a durable metallic mold. Compressed air assists in this seamless process. Within the mold, heating facilitates the bonding of beads, achieving the exquisite pattern geometry desired. Consult the detailed molding process highlighted below for further insights.
4. Pattern Section Assembly and Mounting
Intricate pattern designs are broken down into manageable sections. Post-foaming and drying, these sections are meticulously assembled into a comprehensive pattern and expertly mounted onto a gating system, culminating in a cohesive cluster.
5. Coating of the Clusters
These meticulously assembled clusters undergo a specialized coating process. They are submerged in a water-based refractory coating solution, attaining an ideal thickness of roughly 2mm, ensuring durability and precision.
6. Mold Filling
The expertly coated cluster is strategically placed within a flask. Quartz sand is meticulously filled using a sand raining feeder, and vibration ensures the sand compacts thoroughly around the cluster, leaving only the sprue visible.
7. Casting
A strategically positioned down sprue aligns perfectly with the EPS sprue. Molten metal cascades into the downsprue, navigating through the intricate foam pattern's gating system. The metal's heat decomposes the EPS cluster, intricately filling the mold cavity. For a deeper understanding, examine the decomposition process detailed below.
8. Demolding
With the solidification of the molten metal, the casting reaches completion. Castings are then advanced to the subsequent stage for comprehensive cleaning, ensuring readiness for further application.
9. Sand Processing DepartmentAfter demolding, the utilized sand is efficiently conveyed to the processing system, where it undergoes a meticulous recycling and reuse process, promoting sustainability and efficiency.
