Leading OEM engineering publications have featured the breakthrough design marriage of a CWM mag die cast case with an overmolded polyurethane elastomer.
The new housing, for an advanced Tektronix fiber optic cable tester, offers greater strength and performance over plastic, with part consolidations of the hot-chamber Mg and elastomer unit resulting in a 20% saving compared to similar plastic cases, according to Tektronix engineers. This combination of the two processes is believed to be the first such example incorporating a complex, finely featured magnesium die cast housing.
The application was a cover feature in Design News magazine and was featured in a two-page story in Advanced Materials and Processes magazine. The magnesium and elastomer application was a three-page feature in Modern Metals, and was also featured in Product Design and Development.
