Product Description

Title goes here.

THE MOST IMPORTANT PROCEDURAL STEPS ARE EXPLAINED BELOW:
1. Source Material for the Pattern
This initial stage is absolutely critical for ensuring the success of the lost foam casting process. Carefully select the material based on the specific casting requirements. When working with aluminum die castings, choose expandable polystyrene that includes pentane, an outstanding blowing agent that ensures efficiency and reliability. agent. Conversely, for crafting cast iron and steel parts, a sophisticated copolymer composed of EPS and EPMMA is employed to achieve optimal results.

2. Pre-expansion
The polystyrene exhibits excellent expansion properties, thanks to pentane acting as a high-performing blowing agent. Illustrated below, you can observe a bead that has been pre-expanded using a state-of-the-art fluidity bed dryer.
3. Molding
To produce the actual pattern section, the pre-expanded EPS beads are expertly propelled through a fill gun into a permanent metallic mold using compressed air. Inside the mold, these beads seamlessly bond during the heating process, forming the precise pattern geometry desired. Refer to the detailed molding process laid out below for clarity.
4. Pattern Section Assembly and Mounting
For intricate pattern geometries, complex forms are divided into simpler sections. Following foaming and thorough drying, these sections are meticulously assembled to create a complete pattern and mounted onto a gating system, culminating in a cohesive cluster.
5. Coating of the Clusters
The assembled clusters undergo an essential coating process, where they are immersed in a sophisticated water-based refractory coating, achieving an ideal thickness of approximately 2mm for optimal protection and performance.
6. Mold Filling
The coated cluster is strategically positioned in a flask, and high-quality quartz sand is introduced using an advanced sand raining feeder. Vibration is applied to compact the sand meticulously until the cluster is thoroughly embedded, leaving only the sprue exposed for further processing.
7. Casting
A carefully aligned down sprue is placed over the EPS sprue. Molten metal is expertly poured into this downsprue, efficiently flowing into the foam pattern's gating system. The molten metal intricately decomposes the EPS cluster, thereby filling the mold cavity with astonishing detail. Please review the comprehensive decomposition process described below.
8. Demolding
Once the molten metal solidifies, it transforms to form the final casting. The resulting castings then progress to the subsequent step, where they undergo meticulous cleaning for refinement.
9. Sand Processing DepartmentAfter demolding, the utilized sand is transported to an advanced processing system for efficient recycling and reuse, promoting sustainability and resource conservation.
