Investment Casting Overview
Each department is specialized and essential to the overall process. Wax is the beginning of the whole process and sets the tone for the final product.
Wax Part 1: Tooling
Why is tooling so important?
Since the wax pattern represents the geometry and features of the casting it is critical that you have good tooling that can deliver a consistent wax pattern. Historically tooling was "manual" requiring manual core pulls and manual pattern removal from the tool resulting in potential mishaps and deformation of the wax pattern. Modern wax presses now have computers which can control Semi-Automatic tooling resulting in less human interaction thus decreasing the opportunity for wax pattern deformation. Semi-Automatic tooling cuts down on the total time it takes to produce a wax pattern in addition to delivering a more consistent pattern and final casting.
Using Semi-Automatic Tooling at TPM is one example of TPM's efforts to lower the overall cost to produce a casting which ultimately equates to a lower cost casting for you the customer. Please watch the videos below for a demonstration of both Manual and Semi-Automatic tooling. (Play with sound for increased entertainment value)
