Our Expertise

In 1986 Antonio Mengibar, founder of our company, built the first flowmeter based Filling Machine to give a solution to one of his customers main concern (OTC and Serum Manufacturer): Every few thousand of hours maintenance staff had to replace the seals in the piston pumps to keep the accuracy of the Filling Machines. Where did the missing polymer (waste) go? Then the answer was clear… in every single bottle of Serum.

At that time Filling Machines for small bottles used Piston Filling Technology. It was a must to research an alternative solution. Antonio Mengibar accepted the challenge and developed a new technology used today in many Filling Machines.
