What Are The Raw Materials For Sand Casting?
Have you ever wondered what materials Sand Casting metal product is made of? We all know that Sand Casting is a long-standing and widely used casting process, so what are its key raw materials?
Sand Casting mainly relies on casting sand, binder and metal materials. Casting sand is the main component of the mold, and common ones include silica sand, zircon sand, chromite sand, etc. Silica sand is the most commonly used one. It is low-priced, widely available, and resistant to high temperatures. But sometimes in order to improve the quality of castings, more refractory zircon sand or chromite sand is used.
The role of the binder is to fix the loose sand particles into a certain shape so that the mold has better stability. The most common binders are clay and organic resins, among which bentonite is a very popular one. It expands when it encounters water and can keep the sand mold in a tight structure. Resin binders are used for more sophisticated casting processes and can improve the surface quality of castings.
Metal materials are of course the protagonists of sand casting! Different products require different metals, such as cast iron, cast steel, aluminum alloy, copper alloy, etc. Cast iron is affordable and wear-resistant; cast steel is strong and suitable for parts that bear high loads; aluminum alloy is light and has good heat dissipation; copper alloy has strong conductivity and is suitable for some electronic components or artworks. Only by choosing the right metal material can castings meet different usage requirements.
Now that we are talking about the raw materials of sand casting, you must also want to know what advantages we have in this field? Our factory has advanced sand casting production lines that can produce castings of various specifications, whether large structural parts or small precision parts. We can manufacture them.
We use high-quality sand casting to ensure the stability of the sand mold and avoid defects such as pores and sand inclusions in the castings. Our binder selection is strict to ensure that the mold has sufficient strength and can be demolded smoothly after casting, so that the casting surface is smooth and the size is accurate. In terms of metal raw materials, we have a variety of materials to choose from to meet the needs of different application fields.
In the sand casting process, we use a strict quality control system. From raw material screening, smelting, pouring, cooling to post-processing, each step is strictly tested to ensure that the product meets international standards. Our sand casting has been exported to many countries and is widely used in the automotive, machinery manufacturing, construction, aerospace and other industries.
