What objects are die casted?

In fact, die-cast parts can be found in many things; you are probably just unaware that they are made from die-cast metal. Locks and gears are common finished products. Other examples are hooks, toys, door handles, pumps, power tool housing, golf clubs and general engineering castings.

What is gravity die casting?

Gravity Die Casting is a permanent mould casting process, where the molten metal is poured from a vessel or ladle into the mould. The mould cavity fills with no force other than gravity, filling can be controlled by tilting the die.

What are the applications of die casting?

Die Casting Applications: Die-casting is the largest casting technique that is used to manufacture consumer, commercial and industrial products like automobiles, toys, parts of sink faucet, connector housing, gears, etc. Most die castings are done from non-ferrous metals like aluminum, magnesium, etc.

Why is Aluminium used in die casting?

As a lightweight metal, the most popular reason for utilizing aluminum die casting is that it creates very lightweight parts without sacrificing strength. Aluminum die cast parts also have more surface finishing options and can withstand higher operating temperatures than other non-ferrous materials.

Why is it called die casting?

Dies. The “die” is the term given to the actual tool steel mold that the liquid metal is poured into. The fixed die half is attached to the stationary platen of the casting machine, whereas the ejector half is attached to the movable platen.

Where is gravity die casting used?

Gravity die casting technology is ideal for diverse complex aluminium casting production of automotive parts such as: turbos, brake calipers, knuckles, engine cylinder heads, engine blocks and pistons. It suits many other industries too, from lighting components to kitchen tools.

What is vacuum die casting?

Vacuum-assisted die casting is an important process capability at Kennedy Die Casting. The vacuum evacuation of the die cavity reduces gas entrapment during metal injection and decreases porosity in the casting. The result is a die casting with a higher level of quality. Vacuum systems are only a supplement.

What is flash in die casting?

Flash. A thin web or fin of metal on a casting which occurs at die parting, air vents, and around movable cores. This excess metal is due to the necessary working and operating clearances in a die. Gate. A thin passage for molten metal which connects the runner to the die cavity.

Die Casting Gravity Die Casting: In gravity die casting or Permanent Mold Casting, fluid metal is poured by hand into metal molds. Both ferrous and non-ferrous metals can be casted. Production rate is slow. The casting is not so smooth or dimensionally accurate. 14.

What are the different types of die casting?

Gravity Die Casting/Permanent die casting i- Slush casting ii- Low pressure die casting 1. Pressure Die Casting i- Hot chamber die casting ii- Cold chamber die casting iii- Centrifugal casting 11. Die Casting Gravity Die Casting/Permanent die casting: Molten metal is poured under gravity (i.e. without pressure).

What is hot chamber die casting process?

Hot-Chamber Die Casting: In this pressure die casting process, the basin of molten metal is a part of the m/c. Low melting (less than 700o C) alloys of zinc, tin, and lead are casted in hot-chamber m/c. It is mainly used for small castings (0.03kg to 40kg). The injection pressure are 7 to 35 MPa. 16.
