Product Description

Title goes here.

THE MOST IMPORTANT PROCEDURAL STEPS ARE EXPLAINED BELOW:
1. Source Material for the Pattern
A pivotal stage for ensuring the excellence of lost foam casting is selecting the right material tailored to casting requirements. When it comes to aluminum die castings, expandable polystyrene, enriched with pentane as a dynamic blowing agent, offers optimal results. Conversely, for crafting cast iron and steel components, a robust copolymer blend of EPS and EPMMA proves indispensable.

2. Pre-expansion
Experience the remarkable expansion of polystyrene as it responds to the pentane blowing agent. Below, witness the transformation of a bead in a fluidity bed dryer, achieving prime pre-expansion conditions.
3. Molding
To create precise pattern sections, pre-expanded EPS beads are expertly directed through a fill gun into a sturdy permanent metallic mold using compressed air. Within this mold, the beads forge a bond during the heating process, forming the intended pattern geometry. Discover the detailed molding journey below.
4. Pattern Section Assembly and Mounting
Complex patterns are skillfully divided into simpler segments. After the foaming and drying phases, these segments are meticulously assembled into a full pattern and mounted on a sophisticated gating system to construct an intricate cluster.
5. Coating of the Clusters
Meticulously assembled clusters are immersed in a premium water-based refractory coating, achieving an ideal 2mm thickness through this precise dipping process.
6. Mold Filling
The coated cluster takes its position within a flask, where quartz sand is artfully distributed using a sand raining feeder. Through meticulous vibration, the sand is compacted to fully encase the cluster, leaving only the sprue prominently exposed.
7. Casting
Aligning the down sprue over the EPS sprue, molten metal cascades into the foam pattern's gating system. This molten flow triggers the decomposition of the EPS cluster, filling the mold cavity with detailed precision. Delve into the intricate decomposition process below.
8. Demolding
Once the molten metal has solidified, the majestic casting is unveiled. It then advances to the subsequent phase for comprehensive cleaning and refinement.
9. Sand Processing DepartmentPost-demolding, the sand embarks on a journey to the processing system, ensuring efficient recycling and readiness for future use.
