Non-Stick Coating: A Key Innovation in Foundry Production

Non-stick coatings are an essential component in modern foundry production, widely adopted by leading global enterprises. Their unique properties make them indispensable in the manufacturing process, particularly in the use of EPS (expanded polystyrene) foam models. Below, we outline the key features and advantages of non-stick coatings in this context.

Key Properties and Advantages

1. Absorption of Liquid EPS Phase During Thermodestruction
   Non-stick coatings are designed to absorb the liquid phase of EPS that forms during the thermal decomposition process. This prevents defects caused by the liquid phase and ensures a smoother casting process.

2. High Gas Permeability
   These coatings exhibit excellent gas permeability, allowing gases to escape freely during the casting process. This eliminates the need for vacuum-forming techniques, streamlining production and reducing costs.

3. Ideal for Copolymer Foam Models
   The high gas permeability of non-stick coatings makes them especially suitable for foam models made of methyl acrylate copolymers. This property ensures consistent performance across various types of models.

4. Uniform Layer Distribution
   Non-stick coatings create a uniformly distributed layer over the entire surface of the foam model. This even application enhances the overall quality of the casting process and minimizes potential issues.

5. Exceptional Non-Stick Characteristics
   These coatings effectively prevent the adhesion of materials during casting, significantly reducing the risk of defects such as gas pockets and porosity. This leads to higher-quality castings and lower rejection rates.

6. Defect Prevention
   The use of non-stick coatings reduces or entirely eliminates casting defects caused by the inevitable formation of the liquid EPS phase during the gasification of foam models. This ensures a cleaner and more reliable production process.

7. Durable and Mechanically Resistant
   Once dried, the coating adheres firmly to the foam model's surface, forming a robust layer resistant to mechanical damage. This durability is crucial for maintaining the integrity of the model throughout the production process.

Conclusion

The adoption of non-stick coatings has revolutionized the foundry industry by addressing common challenges associated with EPS foam models. Their ability to enhance product quality, reduce defects, and improve process efficiency makes them a critical tool for modern manufacturing. As technology advances, the role of non-stick coatings will undoubtedly continue to expand, driving innovation in casting processes worldwide.
