Product Description

THE MOST IMPORTANT PROCEDURAL STEPS ARE EXPLAINED BELOW:
1. Source material for the pattern
This critical step in lost foam casting involves selecting the most suitable material based on the desired casting material. For aluminum die castings, the choice is expandable polystyrene, enriched with pentane as a blowing agent, while the creation of robust cast iron and steel parts requires a specialized copolymer blend of EPS and EPMMA. agent. But for the production of cast iron and steel parts a copolymer made of EPS and EPMMA is used.

2. Pr-expansion
Polystyrene, thanks to its pentane content serving as a blowing agent, can be expanded impressively. The process begins with a bead pre-expanded using a fluidized bed dryer.
3. Molding
For crafting the precise pattern section, pre-expanded EPS beads are propelled into a permanent metallic mold using compressed air. Upon heating, these beads fuse together, forming the defined geometry of the desired pattern. Explore the intricate molding process outlined below.
4. Pattern section assembly and mounting of the patterns on a gating system
Due to the intricate segmentation of the complex pattern geometries into simpler forms, these sections must be meticulously assembled into a comprehensive pattern post-foaming and drying. Subsequently, each pattern is strategically mounted on a gating system to form a cohesive cluster.
5. Coating of the clusters
Through an expert dipping process, the assembled clusters receive a protective water-based refractory coating, approximately 2mm thick, ensuring durability and precision.
6. Mold filling
The coated cluster is strategically placed within a flask, where quartz sand is introduced via a sand raining feeder and compacted using a vibration table. This ensures the cluster is entirely enveloped in quartz sand, leaving only the sprue exposed for further processing.
A down sprue is aligned over the EPS sprue. Molten metal is then meticulously poured into this down sprue, flowing seamlessly into the gating system of the foam pattern. As the molten metal encounters the EPS cluster, it decomposes and intricately fills the mold cavity, capturing even the finest details. Examine the decomposition process articulated below.
8. Demolding
After the molten metal solidifies, the casting takes shape. These newly formed castings are then transported to the subsequent process for thorough cleaning, ensuring quality finish and precision.
9. Sand processing department
Post-demolding, the used sand is conveyed to a dedicated processing system, facilitating efficient sand recycling and environmentally conscious production..
