Aluminum Tool for Wax Pattern |
Aluminum Tool with Ejection Pins
Extended to Push the Pattern Out |
- An aluminum tool is used to produce a wax pattern for
the investment casting process. The tool is precision machined to give the desired shape,
details, and dimensional tolerances in the wax pattern.
- The photo on the left above shows the bottom half of
the aluminum tool in which the wax is injected.
- A critical tool feature, shown in the photo on the
right, is the use of an ejection pin backing each cooling pin on the wax pattern. The
ejection pins insure that the pins on the wax pattern are not damaged during pattern
removal from the tool.
