Product Description

Title goes here.

THE MOST IMPORTANT PROCEDURAL STEPS ARE EXPLAINED BELOW:
1. Source Material for the Pattern
This stage is crucial for successful lost foam casting. Selecting the perfect material is paramount to meeting casting requirements. For our exceptional aluminum die castings, we choose expandable polystyrene, infused with pentane, which acts as an outstanding blowing agent to ensure quality results. agent. Conversely, for the robust formation of cast iron and steel parts, a copolymer blend of EPS and EPMMA is employed, providing superior performance.

2. Pre-expansion
In this step, the polystyrene magnificently expands, thanks to the pentane serving as a dynamic blowing agent. Below, observe a flawlessly pre-expanded bead utilizing a fluidity bed dryer for optimal results.
3. Molding
For crafting the actual pattern section, pre-expanded EPS beads are expertly driven through a fill gun into a robust permanent metallic mold using precision compressed air. These beads intricately bond under heat to form the required pattern geometry. Please refer to the detailed molding process outlined below.
4. Pattern Section Assembly and Mounting
Intricate pattern geometries are artfully divided into simpler sections. Post-foaming and drying, these sections are meticulously assembled into a comprehensive pattern and mounted onto a gating system, creating a seamless cluster.
5. Coating of the Clusters
The meticulously assembled clusters are immersed in a water-based refractory coating, achieving a refined thickness of about 2mm, ensuring durability and precision.
6. Mold Filling
The expertly coated cluster is strategically placed in a flask, where quartz sand is precisely filled using a sand raining feeder. Vibration compacts the sand efficiently until the cluster is perfectly encapsulated, leaving only the sprue exposed.
7. Casting
A precisely aligned down sprue is positioned over the EPS sprue. Molten metal is carefully poured into this downsprue, seamlessly merging into the foam pattern's gating system. The molten metal ingeniously decomposes the EPS cluster, filling the mold cavity with intricate precision. Please review the decomposition process detailed below.
8. Demolding
Once the molten metal has solidified perfectly, the casting is complete. The castings then progress to the next stage for meticulous cleaning, ensuring impeccable quality.
9. Sand Processing DepartmentAfter demolding, the utilized sand is efficiently transported to the processing system for recycling and reuse, promoting sustainability and efficiency.
