Specific functions of foundry coating
Casting coating is the basic coating for gravity casting metals, suitable for various metal molds. The particles of casting coating are relatively coarse, but it has good heat retention performance, which can prevent shrinkage and cold shut in castings. It is suitable for thin castings and large flat castings, as well as for upper and lower sprues, wheel hubs, pistons, connecting rods, cylinders, etc. The common coating methods for casting coating include brushing, dipping, spraying, or dipping. Among them, the dipping method has high production efficiency, saves coating material, ensures uniform coating, has low requirements for coating material, is simple to operate, and does not require specialized equipment. It is very popular in practical applications.
1.Compared to phosphate coatings, its unique physical properties determine its superiority.
2. Good breathability;
3. It has obvious heat preservation and insulation effects, with a melting point above 1650℃.
4. After spraying, the adhesive force is strong and it should not fall off. Usually, repairs are needed after one week. Like other coatings, the ZD coating does not require spraying every time it is opened, eliminating the tedious work of dismantling and assembling tooling caused by daily spraying and coating repairs.
5. In comparison, the price is more affordable, significantly reducing the expensive production and casting costs incurred by using alcohol-based coatings or imported coatings.
6. Significantly enhance production efficiency.
The above are the specific functions of foundry coatings. I hope they can help you
