Product Description

Essential Guide: Your Comprehensive Procedural Steps

THE MOST CRITICAL PROCEDURAL STEPS DETAILED BELOW:
1. Procuring Material for the Pattern
This phase is crucial in lost foam casting. Material selection should align with the casting material. For aluminum die castings, expandable polystyrene with pentane as a blowing agent is used. For cast iron and steel parts, a specialized copolymer made from EPS and EPMMA is selected for optimal results.

2. Pre-Expansion
Polystyrene is expandable due to pentane, serving as a blowing agent. Here, a bead is pre-expanded using a fluidity bed dryer, ensuring optimal expansion.
3. Molding
For producing pattern sections, pre-expanded EPS beads are blown via a fill gun into a metallic mold with compressed air. Heating bonds the beads, forming the intended 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, assembled into one complete pattern post-foaming and drying. These patterns are mounted on a gating system to form a cluster.
5. Cluster Coating
Mounted clusters are dipped in a 2mm thick water-based refractory coating, providing a uniform surface essential for casting.
6. Mold Filling The coated cluster is placed in a flask, where quartz sand is filled using a sand raining feeder and compacted with a vibration table, embedding the cluster completely except for the sprue.
7. Casting
A down sprue is placed over the EPS sprue. Molten metal is poured into the downsprue, flowing into the gating system, decomposing the EPS cluster, and filling the mold cavity precisely. Review the decomposition process in detail below.
8. Demolding
Once molten metal solidifies, castings are formed and conveyed to the next stage for cleaning.
9. Sand Processing Department
Post-demolding, used sand is transported to the processing system to be recycled efficiently..
