Once poured into the mold, molten metal begins to cool and solidify. Filling time is very short, to prevent the early curing of any part of the metal. Sufficient molten metal must be poured to fill the entire cavity and all channels in the mold. Pouring can be done manually or by automated machines. After the mold is clamped, the molten metal can be cast from the holding vessel in the furnace and poured into the mold. The molten metal is kept at the set temperature in the furnace. It is necessary to keep the mold half sealed to prevent any loss of material. Then, the core is positioned and the mold halves are closed and securely clamped together. First, the surface of the cavity is lubricated in order to remove the castings after casting. The lubricant used is selected based on the temperature of the sand and the molten metal.Īfter the mold is made, it must be prepared to pour the molten metal. The use of lubricants also improves the flow of the metal and can improve the surface finish of the castings. Lubricant is typically applied to the surface of the mold cavity to facilitate removal of the casting. Mold manufacturing time by the size of components, the number of cores and the impact of sand. Mold making time includes positioning patterns, packaging sand and remove the pattern. Any internal features of castings that cannot be formed by the pattern are formed by separate cores made of sand before forming the mold. When the pattern is removed, the cavity forming the casting remains. The sand is stacked around the pattern, which is a replica of the shape of the casting. A sand mold is formed by putting the sand into each half of the mold. What is Sand Castings ProcessĬreating a mold is the first step in the sand casting process. Not only on casting size but also in a complicated geometry design. Sand casting is a cost-effective and efficient technology. The weight range can be from a few ounces to tons. Including iron, Carbon steel, Aluminum, alloy steel, titanium alloy. Sand casting can cast almost any metal and alloy. If needed, it can be a secondary machining process after casting. Finally, remove the sand shell to get the metal components cooled and formed. Then pour the molten metal into the mold cavity for solidification. Firstly, form a 3D pattern of sand by mold. It is a process that uses sand molds to form metal castings. Sand casting is also known as sand molded casting.
