We have investment die casting for the production of very intricate parts. In investment casting, precise components with minimal wastage, energy and less subsequent machining we produce. Accuracy and excellent details we obtain in this casting, where additional machining is not required. The wax pattern is coated with ceramic material. When the ceramic material hardens, the internal shape is the casting. The wax melts and molten metal need to pour into the cavity where the wax had taken form. We call it an investment because the liquid refractory material needs to invest as a mould pattern. The wax is entirely removed by melting.
Die of Precise Measurement
The size of the master die is calculated carefully by our investment casting die, machine experts. Wax, ceramic and metal casting shrinkage is estimated to get the precise measurement of the die. There maybe a lot of trial and error to get the perfect die. Thus the cost of these dies is more. The metal casting pattern is dipped into the refractory slurry. This slurry is a mixture of grained silica, binders and water. A layer of ceramic is formed on the design. We dip the pattern again and again into the slurry to increase the thickness of the ceramic coating. After the depth seems to be satisfactory, the layer is allowed to cool to get hardened.
High Dimensional Accuracy
Investment casting die manufacturer heats the pattern to melt of the wax, giving a good shape. The residue water and wax ultimately comes out during heat treatment. Now liquid metal is poured into the ceramic cavity. Some time to cool is given for the metal to take the précised shape. We produce extremely complex parts with an excellent finish. High dimensional accuracy with very fewer tolerance patterns we create with our dies. Tiny patterns or enormous patterns we can produce using the investment casting die technique.
Thin walls With Complex Shapes
Investment casting die manufacturer Rajkot does this complicated process with the guidance of experienced engineers. Here ferrous or non-ferrous metals can be used. Patterns with thin walls and complex shapes can be manufactured easily. There is no necessity for machining after manufacturing and saves time and money. Many metals like aluminium, bronze, magnesium, cast iron alloys and tool steel can be used here. This method is a good alternative for welding and fabricating. A single casting can have combined components—more components combined to give more manufacturing efficiency.
