Since 1978, Stemplast has been a trusted name in contract injection moulding and extrusion of plastics.
We provide a comprehensive, integrated service, supporting our customers at every stage of the process, from selecting the most suitable polymers to delivering finished batches. We are committed to quality and to ensuring that every component meets the required geometrical specifications.
1978
Stemplast was founded in 1978 by Mr. Adriano Vezzaro in Dueville, in the province of Vicenza, Italy. He started the business with two small-tonnage injection moulding machines, setting up his workshop in a modest-sized stable. Although only 24 years old at the time, Mr. Vezzaro had already gained considerable experience, having spent ten years working in the plastics moulding industry.
1980
By 1980, the business had become a general partnership, and to accommodate the expansion of its machinery fleet, a new workshop of approximately 300 m² was built. Mr. Vezzaro’s technical expertise and integrity have always been highly valued by his customers, as demonstrated by their continued trust in the company.
1995
In 1995, the company acquired a new 1,500 m² industrial facility in Villaverla (Vicenza), which was subsequently expanded to 2,500 m². Today, the facility houses a fleet of 14 injection moulding machines with different clamping forces, including one designed for two-component injection moulding.
To further expand its production capabilities, the company also introduced an extrusion process for manufacturing plastic profiles and seals, which was later complemented by an in-house workshop dedicated to screen printing and pad printing.
2003
In 2003, the company reached an important milestone in its growth and consolidation by obtaining ISO 9001 quality management system certification, issued by TÜV.
This certification recognised the company’s commitment to implementing structured organisational and production processes focused on quality, reliability and continuous improvement.
2026
2026 marks another important chapter in the company’s growth. In response to the expansion of its activities and evolving production requirements, Stemplast has expanded its facilities to a total area of 2,800 m², creating the conditions for increased operational capacity and even more efficient process management.
In the same year, the company took a further step in its development and consolidation by transitioning to a limited liability company (Società a Responsabilità Limitata – S.r.l.).
Our aim is to meet our customers’ expectations by fostering a respectful and collaborative working environment. We believe that people are at the heart of our company’s success, and we value their professionalism and commitment.
Respect, collaboration and transparency are the fundamental principles that guide us in achieving our goals and supporting the professional growth of our employees.
