New KAESER compressor station

This is an investment in increased compressed air supply, which is necessary for the expansion of the factory. At the same time, we will become more energy efficient and thus also reduce CO2 emissions. In recent weeks, our plant engineering department has been working very intensively with the trades involved to get the project ready for the start of production after the plant holidays. Another contribution by Müller + Müller to protecting the environment.

Comissioning of new siliconization line for vials

Siliconization Müller + MüllerThe construction of an ultramodern siliconization line with connected clean room and an additional warehouse for packaging material is completed.

The new siliconization line is the result of excellent teamwork and represents a consistent step in the further development of the company Müller + Müller. This investment underscores the clear focus of the company on "pharmaceutical vials". Müller + Müller is proud to offer customers a broad and quality-oriented portfolio within the field of tubular glass vials for pharmaceuticals.

With the construction of the new siliconization line Müller + Müller will quadruple its output quantity for siliconized pharmaceutical glass vials. The vials undergo an ultrasonic bath wash, external/internal washing and a spraying unit for the inner surface silicone treatment. Immediately after the siliconization unit, the vials are handed over into a drying tunnel. The packaging takes place in a clean room class 8 in accordance with ISO 14644.

The high precision of the ultramodern siliconization line in combination with a thoughtful quality policy allows an optimal siliconization with minimal silicon in the glass vials.
