Product Description

Title goes here.

THE MOST IMPORTANT PROCEDURAL STEPS ARE EXPLAINED BELOW:
1. Source Material for the Pattern
This stage is absolutely pivotal for achieving success in the lost foam casting process. The selection of material is meticulously based on specific casting requirements. In the case of aluminum die castings, expandable polystyrene enriched with pentane is chosen for its efficacy as a remarkable blowing agent. Conversely, for the crafting of cast iron and steel components, a sophisticated copolymer blend of EPS and EPMMA is employed, demonstrating optimal performance.

2. Pre-expansion
The efficiency of polystyrene expansion is significantly enhanced by the inclusion of pentane, which acts as an excellent blowing agent. Featured below is an expertly pre-expanded bead, utilizing a state-of-the-art fluidity bed dryer.
3. Molding
The creation of the actual pattern section involves propelling pre-expanded EPS beads using a fill gun into a permanent metallic mold, powered by compressed air. These beads undergo bonding within the mold under heat, forming the desired pattern geometry. Detailed insights into the molding process are provided below.
4. Pattern Section Assembly and Mounting
Complex pattern geometries are ingeniously divided into simpler sections. Post foaming and drying, these sections are meticulously assembled into a complete pattern, subsequently mounted onto a gating system to form an integrated cluster.
5. Coating of the Clusters
The assembled clusters are subjected to a sophisticated coating process, involving immersion in a water-based refractory coating, achieving an ideal thickness of approximately 2mm.
6. Mold Filling
The coated cluster is expertly positioned within a flask, where quartz sand is systematically filled using a precision sand raining feeder. Vibration ensures the sand is compacted until the cluster is fully embedded, with only the sprue remaining visible.
7. Casting
Aligning a down sprue over the EPS sprue allows molten metal to be expertly poured into this downsprue. The metal flows seamlessly into the foam pattern's gating system, decomposing the EPS cluster and intricately filling the mold cavity. The detailed decomposition process unfolds below.
8. Demolding
Upon solidification of the molten metal, a flawless casting is formed. These castings then proceed to the subsequent phase for comprehensive cleaning and refinement.
9. Sand Processing DepartmentFollowing demolding, the used sand is efficiently conveyed to the processing system for environmentally responsible recycling and reuse.
