die casting machine-Die Casting and Casting Types

Casting is one oDie castingf the oldest procedures done on metals。 Many products are formed using this method。 Here is an attempt to share the knowledge of casting。
f four types: sand casting， permanent mold casting， plaster casting and Die casting。 All these types of castings have their own advantages and disadvantages。 Depending on the properties of the product requited， one of the casting is selected。

Sand Casting: Sand casting is the oldest casting of the above。 ThisMulti slider die casting machine method of casting is in use since 1950。The texture of theMulti slider die casting machine product depends on the sand used for casting。 The end product is given smooth finishing at the end。 Usually iron， steel， bronze， brass， aluminium， magnesium alloys which often include lead， tin， and zinc are used。

Permanent mold casting: Permanent mold casting uses two pieces of mold。 This molds are joined together and molten metal is pored into this moldzinc die casting。 The hot metal is allowed to cool and the mold pieces are separated。 Some products have metal extrusion which are removed by flash grind or by hand。 Tin， lead anddie casting machine Zinc are commonly moulded using this method。

Plaster casting: Plaster casting is one of the easiest methods。 How ever it is used for metals with low melting point like Coper， Zinc and Aluminum。 This isdie casting machine the easiest process because mold can be made easily in case it brakes in the procedures。

: Die casting is done by introducing molten metal into the mold at high or low pressure。 Earlier only low-pressure diezinc die casting-casting was used but now a days high pressure die casting is used more extensively。 Molds are well designed to give complex products with stunning accuracy and smooth finishing。 They are made of high quality steel as steel has higher melting point。 These molds can be reused thousands of times。 Casts can be single cavity that produces only a single component， multiple cavity that produces multiple identical parts at a time， unit die that produces different parts and combination die that produces different parts in one go。 Usually zinc， copper， aluminium， magnesium， lead， pewter and tin based alloys are used for die casting。
