In the early 2000s, Norman Marrett handed responsibility over to his son, Anthony. Not long after assuming the role, a decision was made to merge with local competitor Micro-Metallic, a company established out of Microponent Development and situated less than a mile away. The merger became Precision Micro, the largest stand-alone contract etching company in Europe.
In 2007, following a planned redevelopment by the local authority, Precision Micro moved to a purpose built etching plant situated next door to the home British car manufacturer, Jaguar. The plant was specified with cutting edge photo-etch equipment, enabling the capacity and precision enjoyed by its customers today.
Heatric continued its growth, and by the early 2010s, the company had to source additional capacity for its etched PCHE plates. As was the case in the 1990s, Precision Micro was the only company deemed capable enough to produce their product, so Meggitt took the decision to acquire Precision Micro from the Marrett family.
