Leomuovi operates in three different locations giving it the advantages of a large company while maintaining the agility of a small one. Our injection molding machine range extends from a precise 35-ton machine to a robust 1600-ton injection molding machine.
CONTRACT MANUFACTURING
Product design
Involve our specialists early in your product design process to ensure a fast and smooth manufacturing run. We will also help you to select the most suitable materials and components for the envisioned application.
Mould manufacturing
During the mould design phase, our tool technicians consider all your needs for optimal results. Our cost-effective in-house tool manufacturing will help improve your competitiveness and make your production schedule more flexible.
Mould procurement
For more flexibility, we have long-term cooperations with different mould producers in Finland, Europe, and China. Together with them, we examine and discuss your product drawings, check the manufacturability, and any need for change.
Manufacturing and assembly
You will receive the needed product batch according to the agreed schedule and contract terms - anywhere from a few hundred to over one million pieces a year. We will manifacture, procure and assemble it for you.
Mould maintenance
We offer regular tool maintenance to our customers because it is critical for long-term usability and functional reliability. It affects the products’ quality and is cheaper than repairing or manufacturing new moulds.
Logistics
Your products will be sent out quickly and effortlessly to the destination named by you with the agreed customised labelling and packaging. In addition, we offer professional packing and flexible warehousing.
Injection moulding
Injection moulding is the most common method for producing plastic parts requiring dimensional accuracy. It is best suited for batches of over one thousand pieces. Our largest injection moulding product weighs 25 kilograms.
PUR sealing of components
Our fully automated production line offers customer-tailored and unique sealing solutions with high quality and excellent reproducibility. We can seal multidimensional pieces manufactured from metal and plastic.
Raw material selection
We will analyse the working environment of your new part or assembly and help you choose the material with the most suitable properties to meet the environmental and all other requirements of the new application.
