  • Foundry
  • Finishing

A common question surrounding the investment casting process is "What do I do with the wax?" How is the wax removed and the metal poured in to the shell? Below are the steps required to prepare the shell as well as remove the wax from the shell.

Investment Casting 101

TPM offers an Investment Casting 101 course for our customers or prospective customers. We have found that many engineers and other personnel have a very limited knowledge base regarding the Investment Casting process, as this is not a common part of the curriculum in engineering school.


TPM can visit your location and conduct an Investment Casting 101 Lunch & Learn. We have had a few customers who have taken advantage of this and the reviews have been great. The goal of the presentation is to share the capabilities and benefits of Investment Casting process. We also discuss part design and what makes a great casting.


The TPM team prides ourselves on our knowledge of the Investment Casting process and would like to help you understand what makes a great casting, and how TPM can work with you on future projects. Please contact Antonio Garcia if you are interested in having TPM host an event at your location.
