TCDC has a reputation for innovative tooling solutions. We run multiple-cavity die cast dies (molds), and are willing to undertake more complex shapes than our competitors. Our domestic and global die cast tooling partnerships allow us to satisfy our customers; whether cost, tool life, or timing is the most important factor in purchasing tooling.

We partner with a variety of tool shops to source our tooling, and value the long relationships that have produced multiple NADCA and IMA die cast Awards.

FAQ: What is Die Cast Tooling and how is it used to create a die casting?

Dies, or die cast molds, are made from alloy tool steel in at least two sections: the fixed die half (cover half), and the ejector die half. When the die casting machine closes, the two die halves are locked and held together by the machine’s hydraulic pressure. During the die casting process, molten metal is injected at high velocity into the mold (die) cavity to form a die cast part.

Variations of die cast tooling / die molds include:

  • Single Cavity Tool - a single cavity tool produces a single casting.
  • Multiple Cavity Tool – a multiple cavity tool produces multiple parts at once.
  • Family Tool – a family tool is a multiple cavity tool that produces multiple part numbers
