Munich 1972. The Olympic slogan “Higher, faster, farther”is picked up by the entire city and inspires a young pro-cess engineer. Dr.-Ing. Heinrich Collin establishes an en-gineering design office for specialty plastic processingmachinery, thereby laying the cornerstone for what willbecome Dr. Collin GmbH.

The company of today continues to expand and boost thespirit of innovation that characterized the founding years.In response to customer requirements, a highly motivatedteam has developed a range of innovative process tech-nologies for plastics processing on the basis of this slo-gan.

The spectrum ranges from• Miniaturized extrusion processes for economical and

fast material development in fields of plastics and phar-maceutical products

• Extrusion systems for product and process develop-ment that have been optimized for minimal materialsusage and time requirement while ensuring reliable scale-up to a production scale.

• Pilot and production systems for special and innovativeplastic products as well as medical and pharmaceuticalproducts.

Together with customers, the company has permanentlyfaced new engineering challenges such as the develop-ment of special films for electronic and battery

Only companies that conduct research and development can set quality standards. We stand to customer-specific solutions – from process technology on a small scaleto production systems in the medical sector.

applications or optical films for monitor screens. Theseactivities have resulted in machinery lines that meet all of the requirements for development of stretched/ oriented plastics. Collin® offers equipment for the following increasingly important fields of technology • Equipment for stretching monofilaments and tape on a

laboratory scale• MDO-Stretching lines with a throughput of up to

300 kg/h• TDO Laboratory-scale stretching lines for film and

sheet with a thickness of up to 3.5 mm• Multifilament spinning equipment for fiber technology

About 10 years ago, Collin® began to adapt its high-precision machinery to the requirements of the pharma-ceutical and medical industries. This included creation of a highly qualified team to ensure compliance with FDArequirements along the entire process chain through validation and documentation.

The company's strategy focuses on the qualifications ofthe individuals who form the backbone of the company.Particular attention is devoted to process technologyknow-how, since only in this way are we able to under-stand the development goals and objectives of our cu-stomers and develop machines that ensure achievementof these. This is how we ensure our future success andcontribute to the success of our customers.

Our programme of innovation

DEVELOPMENT

Constant technological evo lution is amajor concern that top-of-the-rangespecialists in development and engi-neering are faced with in all areas, be it in hardware and electric design orsoftware development.Sometimes however, they achieve asmall technical revolution. This is thecase where the advancement of standard products is enhanced bytailor-made solutions to meet specificcustomer requirements.

PRODUCTION

Modern production and assemblyhalls with generous floor space promote both, the high-quality production of standard machineryand tailored special solutions.A machine acceptance test monitors100 % of all functions and quality features in the area of mechanicaland electrical design as well as insoftware development. Testing and recording all measurement data isprerequisite and basis to award the CE mark and other marks of conformity.

SERVICE

Customer service is a relevant deter-minant of customer satisfaction. With a service team of technicallycompetent and continuously trainedexperts, we can guarantee that our products will retain the quality customers have come to expect – anywhere in the world.
