Rosti Norway

Your Plastic Injection Molding and Toolmaking Partner in Norway

Rosti Norway combines injection molding and in-house toolmaking at two locations sharing the same address in Leksvik. The sites joined Rosti in November 2026 with the acquisition of the Alvi Group and are Rosti’s first locations in Norway. We offer precision molding with robotic automation, in-house decoration and assembly, all supported by our own toolmaking operation: Rosti Industriverktøy.

Founded in Leksvik, Norway over 60 years ago, our company has built a strong reputation as a trusted leader in injection molding. With decades of hands-on experience and deep industry knowledge, we specialize in delivering high-quality, precision-molded components customized to meet our clients’ evolving needs.

Our long-term success is rooted in our commitment to excellence, technical expertise, and continuous innovation. Over the years, we’ve built lasting partnerships with customers across a variety of industries, based on trust, reliability, and consistent results.
We take pride in being more than just a supplier—we’re a long-term partner committed to helping our clients succeed.
