Product Description

Introducing: The Cornerstone of Our Success - Unveiling the Title!

THE MOST IMPORTANT PROCEDURAL STEPS ARE EXPLAINED BELOW: A DETAILED GUIDE TO EXCELLENCE
1. Selecting the Ideal Source Material for the Pattern
Selecting the appropriate material is crucial for successful lost foam casting. Depending on the casting material, the choice varies. For producing aluminum die castings, the optimal choice is expandable polystyrene containing pentane, which acts as a blowing agent. Meanwhile, the production of cast iron and steel parts utilizes a specialized copolymer blend of EPS and EPMMA, ensuring superior results.

2. Pre-expansion Stage
Thanks to the pentane, which serves as a blowing agent, polystyrene becomes expandable, facilitating the pre-expansion process. The resulting bead is pre-expanded using a state-of-the-art fluidized bed dryer.
3. Molding Process
In this phase, pre-expanded EPS beads are blown through a sophisticated fill gun into a permanent metal mold using compressed air. The mold then bonds the beads through heating, forming the desired pattern geometry. Refer to the detailed molding process below.
4. Assembling Pattern Sections and Mounting on Gating System
Complex pattern geometries are segmented into simpler sections for ease of assembly. Once foamed and dried, these sections are combined into a complete pattern. Subsequently, multiple patterns are mounted onto a single gating system to create a cohesive cluster.
5. Coating the Cluster Ensemble
The meticulously assembled clusters undergo a coating process by being dipped into a water-based refractory substance. This coating is approximately 2mm thick, ensuring robust protection.
6. Mold Filling and Compaction
The coated cluster is strategically positioned within a flask. Quartz sand is then introduced via a sand raining feeder and compacted using a vibration table. Upon completion of compaction, the entire cluster is embedded within the quartz sand, leaving only the sprue visible.
7. Casting Process
A down sprue is placed over the EPS sprue. As molten metal is poured into this down sprue, it cascades into the gating system, decomposing the EPS cluster and intricately filling the mold cavity. For a more comprehensive understanding, see the decomposition process below.
8. Demolding Process
Once the molten metal solidifies, the castings are formed. These castings are then transferred to the subsequent shot step for thorough cleaning and refinement.
9. Sand Processing DepartmentUpon demolding, the used sand is transferred to our advanced processing system, where it is meticulously recycled and prepared for reuse.
