Product Description

Title goes here.

THE MOST IMPORTANT PROCEDURAL STEPS ARE EXPLAINED BELOW:
1. Source material for the pattern
Choosing the right materials is crucial for successful lost foam casting. Depending on the casting material, different choices are made. For aluminum die castings, expandable polystyrene (EPS) with pentane as a blowing agent is ideal. agent. For cast iron and steel parts, a copolymer blend of EPS and EPMMA is preferred to ensure optimal performance.

2. Pre-expansion
The unique expandable property of polystyrene is due to pentane, which serves as the blowing agent. Behold the transformation as EPS beads undergo pre-expansion using a fluidized bed dryer, preparing them for the next stages.
3. Molding
In this phase, pre-expanded EPS beads are propelled into a metallic mold using compressed air via a fill gun. The magic happens when heat bonds the beads, sculpting them into the desired pattern geometry. Dive deeper into the intricate molding process below.
4. Pattern section assembly and mounting on a gating system
Complex patterns are elegantly segmented into simpler sections. Post foaming and drying, these sections converge into a unified pattern. Mounted on a single gating system, they form a cohesive cluster, ready for the next step.
5. Coating of the clusters
Clusters are enveloped in a robust 2mm thick water-based refractory coating through a dipping process, ensuring durability and precision in the casting operation.
6. Mold filling The coated cluster is carefully placed inside a flask. With precision, quartz sand fills the space via a sand raining feeder, compacted to perfection by a vibration table. Once compacted, the cluster is fully embedded in quartz sand, leaving only the sprue visible.
7. Casting
A down sprue is expertly positioned over the EPS sprue, guiding molten metal to the foam pattern's gating system. As the metal flows, it gracefully decomposes the EPS cluster, seamlessly filling the mold cavity with intricate detail. Explore the mesmerizing decomposition process below.
8. Demolding
With the molten metal solidified, the castings emerge, ready to embark on the next stage for thorough cleaning and refinement.
9. Sand processing department
Post-demolding, the used sand is skillfully conveyed to the processing system, ensuring it is recycled and ready for future use, exemplifying our commitment to sustainability..
