About us

More than
50 years ago

Lefko started in 1957 and was established in 1974, first operating in concrete and plastic and now exclusively dedicated to custom blow molding. Our 95,000 square feet manufacturing facility houses fourteen high-volume, state of the art blow molding machines ranging from 5 lbs to 100 lbs. We now have a team of over one hundred employees and produce blow molded components as well as completely assembled, market-ready products.

Our commitment
to sustainability

Protecting the environment is an important aspect of our mission. We systematically recover our excess production material in a “closed loop” system, regrind it and reuse it in the molding. Scrap material not suitable to reuse in our fabrication process is also offered to recycling brokers. We are proud to be ISO14001 and EcoResponsible™ certified since 2009 and to be able to boast that we produce absolutely no industrial waste. None.


The Lefko team is committed to actively collaborating on product development, efficiently manufacturing reliable added value plastic blow-molded components, and continuously contributing to sustainable development to ensure peace of mind for its partners and customers.


Take responsibility and have the means to do so.

Express our talents, find meaning in our work and have fun in our relations.

We are constantly improving and dedicated to surpassing ourselves.

Customer Orientation
External and internal customers are at the heart of what we do.


Lefko wants to be strategically located in North America in order to serve customers with national ambitions.
