New Yorker Electronics Providing New Metal Casting Capabilities from AMFAS International
Die Casting, a process similar to injection molding, uses a die or mold to
inject molten metal into the tool which then cools until the part can be
removed and handled without distortion. This is typically used for high-volume
applications. The mold die is commonly made from high performance tool steels,
and its lifespan consists of millions of shots before any deterioration of the steel
tool due to high temperatures and cooling. AMFAS often refurbishes sections of
the tool to save customers the expense of a new tool.
Through AMFAS International, New Yorker Electronics offers hot
and cold chamber and vacuum assist casting and produce parts to 50 pounds with
aluminum alloys, zinc and magnesium. Equipment includes 280T to 2000T high
pressure die casting machines, robotic material handling and centralized
furnace and dumping furnaces.
Although labor intensive, investment casting delivers high precision and
repeatability. Investment casting employs a shell made of ceramic, plaster, or
plastic that is formed around a wax or styrene pattern. The wax pattern is
melted and removed in a furnace and metal is poured into the shell to create
Investment casting can produce parts in almost any metal
with features that cannot be easily machined or die cast. New Yorker Electronics
and AMFAS can advise on the best casting option given the material, part
geometry, volume and other considerations. Part sizes range from 1oz to 150lbs.
Materials used include stainless steel, carbon steel alloys, aluminum alloys, super
alloys (Inconel), copper & brass alloys and iron.
In the case of sandcasting, sand acts as the mold die. A pattern of the
actual part is made typically from wood or metal with two halves representing
the needed part. These patterns are then used to make a temporary die made of
The two halves of the sand mold are joined together and the
molten metal is poured into the sand mold.
Within a few minutes the metal cools and the sand mold is removed using
vibration and mechanical means. With AMFAS International, the sand is then
pulverized, sifted and reused.
Advantages of sand casting are that it is relatively
inexpensive, especially for lower volumes; very large components are possible;
and ferrous and non-ferrous materials are possible with nearly any alloy. AMFAS
uses stainless steel, carbon steel alloys, aluminum alloys, copper & brass alloys
and iron for sand casting.
