The relationship between Heye and Sivesa started in January 1970 when Heye offered a technical service to the Sivesa glass plant for the first time.In 1973 the first contract offering Technical Assistance (TAA) was signed and the first three IS-Machines started operation in 1975, initiating Sivesa´s modernization.
Over the years several contracts have been signed, including the modernization of lines and IS-Machines. In 2011 the existing TAA was extended for the next five years until 2016.
Heye International´s focus is on a long-term base. This success has been confirmed by our customers and has resulted in Technical Assistance Agreements for the last 40 years.
