CWU C-Clamp Matchplate
Proposed Testing Method
​
​For the matchplate to function and preform the task, it is needs to be able to reliably produce a set quantity of C-clamps. This is because these are to be cast with the intent of them to be machined by students for a class. This means that to not waste time and materials, the matchplate needs to be able to produce complete and reliable C-clamps at a set quantity for a number of students who will be be taking said class. To induce these results a proper system of gates and risers will be needed to ensure a proper solid casting. One method in which allows troubleshooting in the pretesting phase is to use a software program which allows one to simulate the casting. This can be used as a benchmark to do a Go-No-Go systems check. This software is only a benchmark for which designs are promising. The true test will come to an empirical pouring of the metal.
Test Plan:
​
Since the goal of the project is the produce a device to successfully press an imprint in green sand, and there is a previously made benchmark model to improve upon or meet. The test is simple and direct. For preliminary stages, all that is needed is several test castings until it is clear a proper matchplate capable of imparting an appropriate set of imprints to produce sixteen fully set clamps from four separate pours. The clamps can be cut in sections and inspected. If air bubbles are in excess, the design will need modification. After this mark has been met, a production test will be done. This is where four to five molds will be made with the matchplate to be poured in unison at one setting.
