Larger parts create too much pressure and distortion of the walls of the mold. Larger castings are best made as a sand cast. The size of the part – Investment casting is best suited for small parts up to a maximum of 80 kgs and 1.2 metres in length.The main points we look at when deciding between Sand and Investment Casting are: Die Casting: – Die Casting, also known as high pressure die casting, is a metal product formation process that involves the pressurized filling of a mold cavity with molten metal to create a formed product.The various common methods of sand casting revolve around the types of binders used to maintain mold strength (resist the molten metal). Sand Casting: – Sand Casting is considered the traditional method of casting.The mold material generally used is Hard Wax, Lost Wax or Lost Foam. Investment Casting: – Investment Casting is the term applied to precision molding using a metal die and ceramic coating in which the chosen metal is injected.We can forge parts up to 50kgs but the sheer energy required to forge larger items make casting a much more viable alternative. We use castings for a wide range of wear parts and components that are too large, complicated, intricate or otherwise unsuitable for the forging process. ![]() A cooking pan is one example of an everyday item made by casting with iron. The material takes the mold’s shape as it cools and is then removed from the mold once solidified.
