Dicasting is the process used to make many commonly used metal parts.
0:05 - 0:10
This video offers a quick introduction to the process.
0:10 - 0:17
Metal dicasting is a manufacturing process where molten metal is injected into a mold called a dye under high pressure.
0:17 - 0:25
When the metal cools and solidifies, it takes the shape of the dye, producing strong and precise parts.
0:25 - 0:28
The dicasting process follows four basic steps.
0:28 - 0:33
First, two halves of dyes are pressed together and clamped to form the part cavity.
0:33 - 0:37
Second, molten metal is injected into the dye cavity under high pressure.
0:37 - 0:40
Third, the metal cools and solidifies.
0:40 - 0:43
Finally, the finished shape is ejected from the dye.
0:43 - 0:52
After these four steps, the mold closes again and the cycle repeats, making dye casting perfect for mass production.
0:52 - 1:01
To use the part created by dye casting, excess material is trimmed away and the part may be machined or coated for its final form.
1:01 - 1:04
There are two main types of dye casting machines.
1:04 - 1:08
Hot chamber machines used for alloys with low melting temperatures such as zinc.
1:08 - 1:14
Cold chamber machines used for alloys with high melting temperatures such as aluminum.
1:14 - 1:17
Dye casting is used for non-ferrous alloys.
1:17 - 1:24
The four most common alloys that are dye cast are aluminum, zinc, magnesium and copper brass alloys.
1:24 - 1:28
It offers strong mechanical properties for durable parts.
1:28 - 1:42
Common products created by dye casting include toys, enclosures, plumbing fixtures, electronic casings, decorative items, automotive components.
1:43 - 1:47
Dye casting creates parts with high precision and repeatability.
1:47 - 1:49
It also produces good surface finish.
1:49 - 1:53
Dye casting is a fast process and it can create complex shapes.
1:53 - 1:56
The same dye can be used to make many different parts.
1:56 - 2:01
So, this process is suitable for creating a large number of parts.
2:01 - 2:03
Thank you for watching.
