About us

Mastering complexity

We are driven by complexity. At Greiner Assistec, we work in partnership with our customers to develop bespoke plastic parts, products, and components, which we manufacture using carefully selected technologies. We are production specialists and know what really matters. “Mastering complexity” is our motto: Starting from the product development stage, we are there to support our customers with technological expertise and innovative services and help them to achieve success by means of precisely tailored processes.

Injection molding

Thanks to Injection molding technology, it is possible to produce millions of plastic parts cost-effectively and efficiently. In conjunction with these economic advantages, the wide variety of different possibilities in terms of shape and surface structure make Injection molding one of the most popular methods of processing plastics. 


The resulting combination of design, color, and function makes Thermoforming a sought-after production technology. As an alternative to Injection molding, it is characterized by lower tooling costs, and it is particularly cost-effective for small and medium series runs.  We offer single as well as twin sheet processes.

Extrusion blow molding

Extrusion blow molding offers a wide range of design possibilities for hollow bodies of different sizes. At Greiner Assistec, we know which equipment particular products require and are therefore able to coordinate products, technologies, processes, and quality standards to achieve optimal results.

Added Values

Greiner Assistec not only takes charge of customized production, it also finishes plastic parts and assemblies in line with individual specifications. We provide end-to-end solutions from a single source: Added values give parts special characteristics and can be integrated into the overall process.


From product information and case studies through best-practice examples, our online magazine contains a host of useful information about successfully completed projects and innovative real-time applications. Click here to discover the world of Greiner Assistec!
