Munich 1972. The Olympic motto ”Higher, faster, further“ fills the whole city with enthusiasm. It also inspires processing engineer Dr. Heinrich Collin to aim for success – even so in an entirely different area.
With the establishment of a design office for special machinery, Dr. Ing. Heinrich Collin laid the foundation for the company Dr. Collin GmbH. Many things have been changing since then.
But the enthusiasm and the sense of innovation of the early days are still driving the company’s business operations and its position in the market. Even after thirty years, COLLIN® is not satisfied with just ”being there“.
The company aims for the top-league and a constant improvement in technical standards in plastics processing, for itself as well as for the entire industry. The corporate philosophy focuses on integrating the special requirements of the customers into a product development concept. This service ensures finding the right solutions for a wide variety of problems in the area of plastics processing.
At the same time however, improving every detail of COLLIN® products and adapting them to global processing methods is central strategy. COLLIN®’s greatest asset is its 70 or more qualified and highly motivated employees.
In combination with a global sales network, they are the mainstay for COLLIN®’s leading position as a supplier of laboratory equipment for plastics processing and testing. The customers are companies in the polymer processing chemical industry, major plastics processors as well as research institutes and training centres all over the world.
