Die Cast Tooling and Its Forms. Die cast tooling are the dies and the molds used for die casting. These die cast tools many forms namely Trim Dies used for die cast parts, Die Cast Family Mold Tooling, Complete Class “A” Die Cast Mold Tooling or Die Tooling, Unit Die Tooling, Prototype Die Cast Tooling Inserts and Die Cast Tooling Inserts.
I would be focusing this article on the latter form, the die cast tooling inserts since among all the die cast tooling, these are the least expensive. These actually are just enough steel to create cavities plus extra steel to put up with the fluctuations of the temperature of molten metal injecting under force. To extend the tooling life, the inserts should be heat treated to reach their proper hardness, not too hard and not too soft. Making it too soft will cause it to easily get damaged or easily wear from erosion and making it too hard, on the other hand could result to the steel cracking due to high temperature. Toolmakers who do not use enough steel in the inserts may reduce its potential life.
The die casting tooling inserts need to be supported by a type of holder so that metal could be injected into it and also to provide a sort of a path for the metal to pass and go in while the gases escape. These gases should be removed because it can produce porosity. This holder of inserts are called unit die, family die or mold base.
Die casting is no simple task. You would need to ask expert toolmakers to do this job for you. You just simply need to look online for you to find the expert that could help you. Varying websites of different die casting companies can be found in the internet. All you need is to choose which is the one nearest you.
