Process: lost mold casting, surface shot blasting and sand blasting, spraying anti-rust paint
Process analysis: The product is a case accessory, the relative wall thickness is thin. Therefore, we chose the lost foam negative pressure casting process to cast this part.
Negative pressure casting technology has revolutionized the casting industry with its incredible ability to accelerate the flow rate of molten iron. The main advantage of this innovative technique is its ability to facilitate the filling of even the most intricate and thin-walled casting parts.
Gone are the days when thin-walled casting would pose a challenge to casting professionals, leading to numerous defects, like porosity, shrinkage, and cold shuts. Negative pressure casting has put an end to such problems, ensuring seamless and high-quality casting production.
This technology works on the principle of creating a vacuum in the mold cavity, drawing the molten iron into the mold at a much faster pace than traditional casting methods. The molten iron flows smoothly and uniformly, ensuring that all parts of the mold cavity are filled evenly and without any gaps. This not only improves the aesthetic appeal of the final product but also increases its functional efficiency.
To further ensure the quality of the product, we employed high frequency vibration during the casting process. This technique helps to eliminate any air bubbles that may be present in the mold, resulting in a smoother and more uniform surface finish. It also helps to prevent any defects or imperfections in the final product.
This kind of process is mostly used for automotive parts casting, thin-wall casting casting and other high requirements on the casting
