Die casting manufacturers offer a variety of services from metal injection molding to precision die cast parts.  Some manufacturers also offer product design, assembly and testing, CNC machining and metal finishing.  Die casting manufacturing services can use several different metal types but the most common are zinc, aluminum, magnesium, copper, and lead. 

There are different advantages to each type of die cast metal.  Zinc is the easiest metal to cast, has high ductility, high impact strength, easily plated and is economical for small parts.  Aluminum is lightweight, has high dimensional stability for complex shapes, corrosion resistant, good mechanical properties, and has high thermal and electrical conductivity.  Magnesium is considered the easiest metal to machine, has excellent strength-to-weight ratio, and is the lightest alloy to die cast.  Copper’s advantages include high hardness, high corrosion resistance, contains the highest mechanical properties for die cast alloys, and strength close to steel.  Lastly, lead has very high density, extremely close dimensional accuracy, and is used for special forms of corrosion resistance.  Many die casting manufacturers can offer recommendations on which types of metal would be best suited for the part creation as a service to the customer.

Die casting equipment and metal dies are large capital costs which limits production to high volume quantities but with only 4 steps in the process, it keeps the incremental cost per item low.  Die casting is done in one of two machine types; either a hot chamber or a cold chamber and is determined by the type of metal.  Hot chambers are best suited for zinc, tin, and lead based alloys.  A cold chamber production method is best suited for aluminum, zinc alloys with large compositions of aluminum, magnesium, and copper. 

Die casting manufacturers offer a variety of services depending on the needs of the business.  From prototype design, to metal choices, to assembly and testing, die casting is the most efficient and cost effective solution to high volume part creation.
