Casting Molds

Permanent Casting Molds: Although these permanent casting molds are not as flexible as the sand castings which allow to be used in different metal patterns or designs but these lower the cost of producing the part. When there is a production run of more than 1000 parts the permanent casting molds would produce much lower piece of cost part. Apart from this, the break even point also depends on the density of the part. There are more complex parts that are favored when you use these permanent casting molds. The typical part size would be around 50g to 70 kg and the basic materials used are medium and small parts that are made from magnesium, aluminum and brass and also their alloys.

Slush Casting Molds: The slush casting molds are actually a special type of permanent casting molds in which the molted metal is not allowed to solidify completely. After gaining the desired wall thickness the still not solidified molted metal is then poured out. This is basically used in order to make void ornamental objects like lamps, candlesticks and statues.

Corthias Casting Molds: This type casting molds is yet another variant of the permanent casting molds in which basically a plunger is used to pack the molted metal through the spure hole. This type of process allows thinner walls and to produce greater details.

Vacuum Permanent Casting Molds: This is also another type of permanent casting molds which is also similar to low pressure permanent casting molds. In this type vacuum is used rather than a pressure. You can make thin wall casting through this type of casting molds like in the other low pressure casting molds. Apart from this the results are high as there are no risers used.
