Product Description

Title goes here.

THE MOST IMPORTANT PROCEDURAL STEPS ARE EXPLAINED BELOW:
1. Source Material for the Pattern
In the fascinating world of lost foam casting, selecting the right source material is pivotal. For aluminum die-castings, expandable polystyrene with pentane as a blowing agent is utilized, ensuring optimal results. Meanwhile, for cast iron and steel parts, a specialized copolymer of EPS and EPMMA is employed, tailored for their distinct needs. agent. But for the production of cast iron and steel parts a copolymer made of EPS and EPMMA is used.

2. Pre-Expansion
Thanks to the pentane acting as a blowing agent, polystyrene exhibits remarkable expandability. Behold, a bead pre-expanded with precision, using a fluidity bed dryer for consistency and quality assurance.
3. Molding
In the creation of the pattern section, pre-expanded EPS beads are expertly blown through a fill gun into a meticulously crafted metallic permanent mold, using the power of compressed air. Witness the magic as beads bond post-heating, forming the desired pattern geometry with finesse. Delve into the intricacies of the molding process below.
4. Pattern Section Assembly and Mounting of the Patterns on a Gating System
Complex pattern geometries are ingeniously segmented into simpler sections, seamlessly assembled into a complete pattern post-foaming and drying. This masterpiece is then mounted on a unified gating system, forming a cohesive cluster ready for the next stage.
5. Coating of the Clusters
The clusters, now mounted, undergo a transformation through a water-based refractory coating, approximately 2mm thick, applied by dipping. This layer is critical for enhancing durability and precision.
6. Mold Filling
After solidification, the artistic castings emerge, ready to be conveyed to the next phase for detailed cleaning and finishing touches.
A down sprue is masterfully positioned over the EPS sprue, directing molten metal to the gating system with precision. As the metal flows, the EPS cluster decomposes, intricately filling the mold cavity down to the finest detail. Explore the decomposition nuances below.
8. Demolding
As the molten metal solidifies, the castings take form, poised for the subsequent step in their journey towards perfection, where they will be conveyed for further refinement.
9. Sand Processing Department
Upon demolding, the used sand is transported to a cutting-edge processing system, diligently prepared for recycling and reuse, underscoring our commitment to sustainability..
