Many times, guests request some effect, and because of the design, materials and other reasons, it is likely to appear that some requests can do, and sometimes can not do. Because each material and every method has its own characteristics and limitations. For example, we often need to explain the effect of fog paint, sand and spray paint and sandblasting to customers. Although both are used to assist clients in covering up and avoiding the problem of the metal being unpolished, but the specific effect of their respective effects is very difficult to master and distinguish quickly. So here, I'd like to share with you the characteristics, advantages and limitations of these three approaches.
The fog paint is a thin layer of fog paint, it is similar to our entry into the paint, they are also colorful, the most commonly is transparent paint. It is commonly used in 3D products with sand release. The effect of fog paint is the feeling of fog, without sand. Compared with sandblasting, fog paints are more foggy and smaller, just a thin layer of metal. They are not embedded in the product and can be easily scratched with a nail. It is suitable for all kinds of pressure die casting or nibble type, such as copper, iron, zinc alloy, aluminum, etc.
Sand release is a kind of metal particle, which is directly added to the mold of the product through discharge treatment, and is part of the design of the data product. So it came out with the product die pressing/die-casting. No post-process processing. The effect of sand release is "inborn", so other finished products have the same effect as other protruding metals. That is to say only the feeling of gravel, no fog. It is suitable for all kinds of pressure die casting, such as copper, iron, zinc alloy, aluminum, etc. But zinc alloys usually require a thicker gravel. Because the zinc alloy density is relatively small, the gravel is too fine, the finished product can not see the effect at all. Moreover, sand release is not suitable for bite-type products, since there is no such thing as molds.
The sandblasting is used to spray the metal sand particles directly onto the surface of the product, and then directly impact the sand points produced by blasting the carborundum and directly impacting the copper pieces. Sandblasting can not be selected for local treatment, and it will be polished after blasting in normal conditions so as to make a sharp contrast between the protrusion of the product and the concave metal. The bulge is bright after polished, and the air is sprayed with sand after it is sprayed with sand. The effect of sandblasting is fine and uniform, with the feeling of fog, and it is suitable for cutting copper products. If the bite version of copper must be done, the thickness of the product needs to be more than 1.2 mm thick, and the scrap rate is relatively high.The iron and zinc alloys are not suitable. It's all about their density.
Sanding with fog painting - because the sandblasting combines the effect of sand and fog paint, the effect of fog is also the feeling of grit. But it's not good for zinc alloy and iron, therefore, in order to achieve the effect of fog, the factory will choose to add sand and spray paint on the same product. The difference between sand blasting with fog paint and sand blasting is that the sand blasting is more delicate and even. And the effect of sandblasting fog can not scrape, and fog paint can be scraped off with a sharp tool.
