We have been ordering injection-molded parts for our paper machine unit from Leomuovi Oy for more than ten years. Our technical requirements for precise dimensions, surface smoothness and chemical resistance of components are very strict. With the help of the plastic parts made by Leomuovi, we have been able to replace expensive steel elements and make our production more efficient and flexible, which benefits both our company and our customers. Collaboration with Leomuovi´s team is always smooth and effective.

4. The manufacturing process is started
5. Samples are sent to you for testing and evaluation
6. The accepted injection molding tools are delivered to Leomuovi Oy's site

Meet our team

Leomuovi Oy started its journey as an independent plastic injection molding company in 1984, when Leo Koskinen decided to buy the plastic part production unit of the ventilation systems manufacturer Lapinleimu Oy. Starting in 2001, two energetic entrepreneurs - Risto Kalliainen and Sami Rantala - together with our team of resourceful injection molding specialists have continued to develop and diversify our production of plastic parts.

Thanks to our joint efforts and enthusiasm to create valuable products, Leomuovi Oy is growing sustainably and continuously. Nowadays our factory manufactures a broad palette of customized industrial components and appliances from different commodity and engineering plastics. Every year we add new products to our own product portfolio.

Our customer base is growing both in Finland and abroad. Products made by Leomuovi are now used on all continents.
