Welded Bellows for Freeze Drying, Pharmacuetical Packaging and more...


The Life Sciences Equipment Market, composed of Biotech, Pharma and Medtech sectors, must ramp-up to support the acceleration in time to market for vaccines and other biologics and the increased rate of drug approvals by the FDA.

GMP [Good Manufacturing Practice] regulations developed by the US FDA, require that manufacturers, processors and packagers of drugs, medical devices, some food and blood take proactive steps to ensure their products are safe, pure and effective.

This puts pressure on the component and equipment assembly companies to not only shorten the development cycle but increase capacity for worldwide demand. It also increases the importance of excellent equipment reliability and compliances, as there is little time for recovery and greater missed opportunity cost.
