Ever wonder how they created that awesome statue or machine part? Even the sand we play with at the beach can be used to make these things. That’s right! Another typical sand uses is the one made for kids playing to make those amazing castles, even pure superheroes – yes that same building components can be also used in another process called casting with Products from Boqiao.
Foundry sand is a unique blend, consisting of sand, clay and several other substances. The clay acts as an adhesive to bind the grains of sand together, making it a strong and long-lasting mold like a Gravity die casting machines from Boqiao. The reason this is significant is that the foundry sand has to be able to withstand extremely high temperatures when we pour in hot liquid metal. But if the sand mold fails to withstand that heat, it could easily shatter under pressure and your project will be destroyed.
Dry Sand: Here when we need the product to form smooth surface, so in that case dry sand is obtained. Sand that is too dry — more clay in it, so the sand will hold together with tighter detail. This makes it ideal for creating molds that need a high level of detail and shiny finish like Low Pressure die cast machines from Boqiao.
Resin Sand: This sand is a bit unique as it contains the special material resin on its surface. This resin helps in binding the sand particles and therefore makes a strong mold like Aluminum casting parts. Because it has a good carrying capacity, especially for making large and heavy product of copper type casting mould wireless resin sand cope.
The sand is combined with a mixture which sets the resin. The mold is now filled with molten metal, as in the other processes mentioned earlier in like a BQ melting furnace.
