Custom technical profiles for industry
Plastic extrusion is one of the most reliable and efficient technologies for manufacturing plastic profiles for the main industrial sectors. The ability to process different polymers and customise shapes, materials and technical characteristics makes it possible to produce high-performance components designed to meet specific application requirements.
At Liana, we develop custom extruded plastic profiles, supporting customers from design to series production while guaranteeing quality, precision and production continuity.
What is plastic extrusion?
Extrusion is a manufacturing process in which plastic material is melted and forced through a die that defines its geometry. The component is then calibrated, cooled and finished to obtain a product with high dimensional accuracy and consistently reliable characteristics over time.
Custom solutions for every application
Every project requires specific expertise, materials and performance. This is why we manufacture custom plastic profiles, selecting the most suitable polymer and developing tailored technical solutions. We process PVC, polycarbonate, ABS, polyethylene, polypropylene, TPE and other technical materials, including through co-extrusion and tri-extrusion processes.
Application sectors
Our solutions are used in the doors and windows, building, lighting, furniture, refrigeration, industrial and transport sectors. Each profile is designed to ensure functionality, reliability and long-term durability.
From design to production
We manage the entire production process, from profile and die design through to industrial production and quality control. This integrated approach enables us to provide components that meet customer specifications and deliver consistently reliable performance over time.
Why choose Liana
Our experience in plastic extrusion, the ability to develop customised solutions and the technical support at every stage of the project make Liana a reliable partner for manufacturing plastic profiles for a wide range of industrial applications.
