The Ensinger Group is a manufacturer engaged in the development and manufacture of compounds, semi-finished products, technical parts, composite materials and profiles made of engineering and high-performance plastics. The family-owned enterprise is represented in major industrial regions with manufacturing facilities or sales offices. The main office is located in Nufringen/Baden-Württemberg, Germany.

The company was founded in 1966 by Wilfried Ensinger.^[2] First areas of focus included the manufacture and sale of thermoplastic engineering plastics. Closely linked with this technology, the company worked on further development of the extrusion process and application technology. A short time after relocation of the headquarters to Nufringen, Ensinger launched the production of components manufactured by machining semi-finished products. In 1977, the company dispatched its first volume-produced thermal insulating profiles made of glass fibre-reinforced polyamide 6.6 to manufacturers of aluminium windows.^[3] A second plant was erected in 1980 in Cham/Bavaria. After the launch of other product lines, Ensinger founded a number of additional subsidiaries in Europe,^[4][5] North America,^[6][7] South America and Asia. Since 2007 the company has been present in China with its own production facility.^[8]

The products are used in a wide variety of industrial sectors, including mechanical engineering, in the automotive and aviation industry and in medical technology.^[9] The technical solutions based on thermoplastic polymers are also very common in the food industry and in electrical and semiconductor technology. In many cases, high -performance plastics replace other materials such as metals or ceramics. The segment disc distance made of insulating plastic for insulating glass was sold to the Fenzi Group in 2019.^[10]

The company group employs a total workforce of ca. 2,600 in 33 locations.

To process the thermoplastic polymers, Ensinger uses a number of production methods, in particular compounding, extrusion, machining, injection moulding, casting, sintering and compression molding.

The spectrum of materials used ranges from engineering plastics (such as PA, PET and POM) through to the category of highly temperature-resistant high-performance plastics (such as PEEK,^[21] PPS, and PI).

Thermoplastic polymer products are used in different fields, including the automotive and aerospace industries, mechanical engineering, medical technology,^[22][23] the electrical and semiconductor sectors and food industry.

On 1 February 2022, it was announced Ensinger had concluded a joint agreement to acquire INEOS Styrolution's StyLight thermoplastic composite materials business.^[24]
