Die casting is a metal forming process in which molten metal is put under pressure and injected into a die. The molten metal enters the die cavity through sprue holes in the fixed die half. The melt is directed to the cavity by runners (passageways) and gates (inlets) in the ejector half. Locking pins on the die secure the two halves together. The metal, kept just above its melting temperature, quickly solidifies into the shape of the die casting. Ejector pins remove the die cast part.
Die castings are made from alloy tool steels. They have at least two sections to permit the removal of castings, the fixed die, or cover, half and the ejector die half. Some dies also have parts, such as removable slides and cores, to produce holes, threads and other desired shapes in the casting. Openings in the die allow the addition of coolant and lubricant. Dies are either air- or water-cooled. The cooling of the die provides for quick cycling and is one of the factors in the high rate of production. It also gives a fine grain structure and superior strength
and finish to the metal
castings. The molds used by die casting manufacturers
will perform up to 5 million shots in its lifetime.
The services provided by die casting manufacturers have many advantages over other processes. Die casting is efficient and economical, offering a wide range of durable shapes and components. Little or no machining is required after die castings are made because the process provides very close tolerances for even complex part shapes. Metal castings can be easily plated or finished. Die castings are dimensionally stable and heat resistant. These lightweight parts, even while having thin walls, retain the strength of an alloy because they do not consist of separate parts welded together.
Die casting manufacturers utilize a number of materials, including zinc, aluminum, magnesium, copper, lead and tin. Zinc is the easiest alloy
to cast, has a low melting point and is economical and easily palatable.
Zinc also has high impact strength, offers high ductability and promotes
long die life. Aluminum alloys possess high dimensional stability for
complex shapes and thin walls. Aluminum
die casts are of a lightweight alloy
that has good corrosion resistance, mechanical properties, high thermal
and electrical conductivity and strength at high temperatures. Along
with being the easiest alloy to machine, magnesium is also the lightest
typically die cast. Magnesium die casting also has excellent strength-to-weight
ratio. Copper is one of the hardest alloys and offers the highest mechanical
properties of any other alloy that is cast. A dimensionally stable alloy,
copper has high corrosion and wear resistance and strength approaching
that of steel parts. Lead and tin are used for special forms of corrosion
resistance. Although they have high density, parts with extremely close
dimensions are able to be formed from lead castings and tin castings.
Aluminum
die castings are commonly used in the production
of hardware and tools because of the great resistance of aluminum castings
to corrosion and high temperatures, as well as their conductivity.
In addition, aluminum castings are used in applications requiring the
production of intricate part features and components.
Automotive castings, which include engine blocks, cylinder heads,
brake calipers and discs and suspension components, are increasingly
being
manufactured out of lightweight material, such as aluminum, to economize
fuel consumption by decreasing the overall weight of the vehicle.
Brass castings are used in the architectural and construction industries
and in decorative applications, such as doorknobs.
Bronze castings are used in applications requiring high strength,
making them ideal for use in the architectural and construction
industries.
Copper die castings are used in applications requiring exceptional
strength and resistance to corrosion. Copper castings consist
of brass and bronze castings.
Die
casters shape metal by putting pressure on molten metal in a die.
Gravity die castings are produced by pouring molten aluminum into
a metallic tool at a casting temperature of 750˜. Gravity
die castings have good tolerances and surface finishing.
High pressure die castings have very thin walls. The metal enters
the die cavity at high speeds and under great pressure,
which increases the chance of porosity.
Lead die castings offer great corrosion resistance and are used in
the production of parts in the plumbing industry. Lead
castings, particularly tin castings, also provide close production
tolerances but are generally
not as strong as other diecast metals.
Low pressure die castings are formed when metal from an airtight
furnace is transferred into a metallic tool through
a rising tube. Low pressure
die casting is suitable for relatively small lot sizes
and for applications in which heat treatment is needed to improve
the
mechanical
properties.
Magnesium die castings are particularly useful in applications where
weight is a factor. Magnesium die castings are very
lightweight and cost-effective, especially in comparison to other
diecast
metals.
Zinc
die castings are often used in the production of small parts
for the electronics and automotive industries.
Zinc castings lend themselves
well to secondary operations such as painting and
plating.
Common Terms Related to Die Castings
Biscuit – An excess of molten metal that is leftover
in the shot sleeve of a cold chamber die casting machine. Biscuits are
considered part of the cast shot and are removed from the die with the
casting.
Blister – Die casting deformation consisting of a gaseous bubble
on the surface of the casting and a hole in the casting underneath the
bubble.
Checking – Small cracks on the surface of a die caused by repeated
heating of the die surface by injected molten alloys. Checking produces
corresponding raised veins on die castings.
Cold Chamber Machine – Die casting machine suited for aluminum
alloys that avoids the subjection of the pressure chamber and injection
equipment to the molten metal by directing the metal through a channel.
Die Cavity – The hole in the die that reflects the shape of the
part to be die cast.
Die Lubricants – Liquids applied to the die to prohibit soldering
and make it easier for the casting to be released.
Ejector Plate – A plate that actuates the ejector pins attached
to it.
Flash – Excess metal on a die cast part extending past the parting
line of the die set, which blocks metal from flowing past the die lines
and filling the die impressions.
Hot Chamber Machine – Die casting machine in which the pressure
chamber is subjected to the molten metal through immersion. Hot chamber
machines are used in the die casting of metals with low melting points,
such as zinc die casting, copper die casting and magnesium die casting.
Insert – Metal piece placed inside the die cavity to produce certain
features on and within the die cast part.
Metal Saver – Core utilized to prevent sections of excessive thickness
from occurring and to reduce the amount of metal used in a metal casting.
Overflow – An opening or cavity on the parting line of the die
outside of the main die cavity into which unacceptable metal flows during
the shot process. Reasons for metal unacceptability include improperly
heated metal and metal that contains impurities.
Parting Line – A line along the surface of a die casting reflecting
the small space between the die halves.
Porosity – A casting imperfection consisting of a hole or void
in the casting caused by air trapped in the casting.
Runners – Horizontal mechanisms connected to the sprue that transfers
the molten metal from the sprue to the mold.
Shot – The process in which the metal is poured into the die. The
shot may also refer to the die cast part as it exists as a cast before
secondary operations are performed to remove flash and to fix imperfections
in the casting.
Sprue – Mechanism with which the molten metal first makes contact
during the shot process. The sprue transfers the molten metal to the
runners.
Trim – The process in which overflow, flash and other parts are
removed from the die cast part or shot.
Vent – An orifice in the casting die that facilitates the release
of air from the die cavity into the atmosphere to prevent casting imperfections,
such as porosity.
Waterline – The channel in the casting die into which water flows
to precipitate the cooling of the die casting.
