Since 1980 “IP Pomari Innocente” has been designing and manufacturing plastic injection moulds for household goods, die cast plugs, water tanks and technical articles.

With 30 years’ experience supplying moulds for one of the main Italian die cast plugs manufacturer, the 1st of January 2009 the individual holding ‘IP’ was converted into KERZ snc. after Mr. Marco Pomari and Ms. Chiara Pomari –the owner’s son and daughter- joined the company. The company has enlarged and set up a new division. It now produces both moulds and its own die cast plugs. After-sales service constitutes an important added value for our clients: we are committed to providing real-time support in case action were required. In 2018 Samuele Pomari joins the company after a brief experience abroad. He will be responsible for the company's international business.
