Andrew Montgomery

Non-Metallics Engineer
Shamrock Plastics worked diligently to manufacture an extremely complex vacuum formed dash assembly. Due to the design requirements; this assembly required the utilization of 3 forming tools to produce the desired result. Shamrock took a leap and produced the component on time and on budget. Job well done! Andrew Montgomery Non-Metallics Engineer
