Die Casting Process
Die Casting Description: Molten Metal is injected, under pressure, into hardened steel die casting dies,
often water-cooled. The die casting dies are opened, and die castings are ejected. Many times thousands of die casting
parts each day are produces.
Metal:
- Aluminum 360, aluminum die casting alloy
- Aluminum 380, aluminum die casting alloy
- Aluminum 383, aluminum die casting alloy
- Aluminum 413, aluminum die casting alloy
- Zinc die casting alloys
- ZA die casting alloys
Size Range: Not normally over 2 feet square.
Tolerances:
- Aluminum ± .002"/in
- Zinc ± .0015"/in
- Add ± .001" to ±.015" across parting line depending on size
Surface Finish: 32-63RMS
Minimum Draft Requirements:
- Aluminum & Mag 1° to 3°
- Zinc 1/2° to 2°
Normal Minimum Section Thickness:
- Aluminum: .06" Small Parts; .09" Medium Parts
- Zinc: .03" Small Parts; .06" Medium Parts
Ordering Quantities: Usually 1,000 and up
Normal Lead Time:
- Samples: 2 to 4 weeks
- Production: Starts usually within two weeks after approval

Zinc #3 weighs 2.44 times more than aluminum, the ZA-8 weighs 2.3 times more than aluminum,
and the ZA-27 weighs 1.84 times more than aluminum and the greater weight will effect the overall part cost.

Die Casting Technical Terms
High Quantity High Pressure Die Casting Production
Thousands of high pressure die casting parts can be produced in a single day with the right die casting tooling
and proper high pressure die casting aluminum part design. Kinetic Die Casting has produced quantities of 20,000 to 30,000
high pressure die casting aluminum parts a week in some cases. We can design or work with your designer to develop high volume
high pressure aluminum die casting tooling.
Low Quantity High Pressure Die Casting Production
We will produce for our customers low quantities of high pressure aluminum die casting parts, as few as 100 high pressure
die casting parts. The cost to produce and complete the high pressure die casting parts is higher than the larger
quantities, so the high pressure die casting part price is higher. Some die cast part manufacturers will not bother
with quantities under several thousand, so this becomes an advantage to Kinetic Die Casting customers.
High Pressure Die Casting Tooling
High Pressure die casting molds, sometimes referred to as high pressure die casting tooling, are made from steel
hardened to withstand high temperatures and extreme pressures. There are many types of high pressure die casting
tooling from simple inexpensive inserts to complete high pressure die casting dies that are dedicated to only one aluminum part.
Once a high pressure die casting tool is produced, the cost to make high pressure die casting parts is very little.
We have an in-house toolmaker who can make your high pressure die casting die or fit your inserts into one of our
dies or holders at a very competitive price.
Die Casting Aluminum Part Quality
The dimensional accuracy which
Kinetic Die Casting, Inc. maintains is one of our outstanding characteristics. We will create an "Operation Sheet"
that has all the inspection points necessary to ship you the high pressure die casting aluminum parts you want.
We provide a "Certificate of Conformance" with each shipment of high pressure die casting aluminum parts.
For a quotation on an existing aluminum die casting or aluminum part of another process to get a die casting aluminum part
quote, contact us with this
aluminum part or die casting tooling request for quote form, or just send the part for a quote.
The dimensional accuracy which we maintain is one of our outstanding characteristics.
Because of the excellent dimensional accuracy and the smooth aluminum surfaces, most die castings require no machining.
In many cases, aluminum die casting can replace steel, increasing strength and reducing part weight.
