ATHI has been trying to supply our customers with good quality castings in yhe foundry industry. To fully realize the potential of the sand molding plant, ATHI brings the world’s selection of continually advancing sand preparation and control technologies to match the specific needs of any project. We can deliver optimized, high-performance solutions that maximize the potential of a molding plant to produce high-value, high-profit metal castings.
Sand Treatment
Sand casting is one of the few processes available for metals with high melting temperatures, such as nickel, steels, and titanium. Sand casting is the most widely used casting process due to its flexibility, heat resistance, and relatively low cost.
Sand treatment is recycling the used foundry sand through sand treatment system equipment. The preparation of moulding sand and sand core is the central part of the sand processing system. The moulding sand configured according to a specific composition is mixed in a sand mixer. After meeting the quality requirements, it is sent to the moulding and core making department for use. To accomplish the above tasks, it is necessary to have many processes to process raw materials, use sand and moulding sand, and have various transportation equipment and auxiliary devices to connect the process equipment to form a sand treatment system.
Moulding sand is the core of the sand casting process. It must maintain a good shape and capture the fine details of casting, yet be permeable enough to allow gases to escape. It cannot crumble or sink on itself under the strain of having the moulding pattern removed from it or while it is filled. When it is inverted, it must not lose its form: the mould parts have to stay proper while clamped together.
Casting
The foundry process is centuries old. Foundry is more than making metal parts for engine, rail, and pipe components. About 90% of all manufactured consumer products use metal castings for their module parts. Additionally, metal casting foundries rely on metal recycling as a cost-efficient source of raw material, significantly reducing wasted scrap metal that might end up in landfills.
A metal foundry or factory casts metals into forms by melting them down and pouring the molten liquid into sand, metal, or ceramic mould to create complex parts. Then let the metal cool, and the liquid solidifies. The casting, or shaped metal, can now be used to produce more difficult and uniquely shaped products or parts. All primary metals can be cast. The most common metals processed are iron, steel, aluminium, and copper-based alloys, but other metals such as bronze, brass, magnesium, and zinc can also produce castings so that parts of any desired shape and size can be formed.
Casting creates metal objects by pouring liquid metal into moulds, where it cools and hardens into the mould’s shape. While the principle is simple, there are many different ways of casting metal. To make an object from idea to reality, designers must identify the aesthetic and the physical needs of the final product and, from there, find the simplest way to produce those qualities. The complexity of the design and the stresses the last object must withstand help determine the metal; how the metal behaves in liquid, solid, and cooling states will dictate requirements for the mould. Excellent casting design knows all the ingredients and processes involved to get to the final product.
Finishing is the last stage in the casting process, and it often involves grinding or sanding the component to achieve the desired final shape and finish. Many castings are machined in milling centres to ensure a tightly controlled finish, creating better dimensional capabilities.
