ASQ member 2012


Green Belt Project (TYCO) – Revised production operation of extruder machine to run same family material rather to retool and do material change over intermediately in order to produce more a consistent product resulting in less scrap.

0 Degree Draft Pin (PLASTIKON) – Led tooling in development of a polycarbonate and glass filled part which required a 0 degree receptacle hole. This was done by providing air cooling on the pins so as to not reach the glass transitioning temperature of the material.
