Product Description

THE MOST IMPORTANT PROCEDURAL STEPS ARE EXPLAINED BELOW:
1. Source Material for the Pattern
This essential step in the lost foam casting process involves selecting the appropriate material based on the casting type. For aluminum die castings, we opt for expandable polystyrene containing pentane to act as a blowing agent. agent. Conversely, for creating cast iron and steel components, we utilize a copolymer composed of EPS and EPMMA.

2. Pre-Expansion
The expandable nature of polystyrene is due to pentane, which serves as a blowing agent. Below is a bead pre-expanded using a fluidity bed dryer.
3. Molding
In producing the pattern section, pre-expanded EPS beads are propelled into a metallic permanent mold using compressed air and a fill gun. Within the mold, heating bonds the beads to form the desired pattern geometry. Please refer to the detailed molding process below.
4. Pattern Section Assembly and Mounting on Gating System
Complex pattern geometries are divided into simpler sections for ease of assembly. Once foamed and dried, these sections are combined into a complete pattern. Subsequently, the patterns are affixed to a gating system, forming a cohesive cluster.
5. Coating of the Clusters
The assembled clusters are coated by dipping in a water-based refractory coating, achieving a thickness of approximately 2mm.
6. Mold Filling The coated cluster is placed in a flask, where quartz sand is distributed by a sand-raining feeder and compacted using a vibration table. Upon completion, the cluster is fully encased in quartz sand, with only the sprue exposed.
7. Casting
A downsprue is aligned with the EPS sprue, allowing molten metal to pour into it and proceed into the gating system of the foam pattern. The heat decomposes the EPS cluster, enabling the metal to intricately fill the mold cavity. Examine the decomposition process below.
8. Demolding
Once the molten metal solidifies, the casting is formed. The castings are then transferred to the next stage for thorough cleaning.
9. Sand Processing Department
Post-demolding, used sand is conveyed to the processing system for recycling, ensuring sustainable and efficient sand reuse..
