Cleanroom Blow Molding
Our Processing Capabilities
Containers for All Requirements
Röchling Medical has more than 60 years of experience in the processing of thermoplastics in the blow molding process. In this highly specialized area we offer a unique range of process technologies in cleanrooms GMP classes C and D:
- Extrusion blow molding
- Multi-layer extrusion blow molding
- Injection blow molding
- Stretch blow molding
This enables us to produce a wide range of pharmaceutical primary packaging options, for liquid, solid and powdery pharmaceutical dosage forms, as well as consumables for diagnostic liquids. Container sizes range from small vials to large multi-liter canisters for diagnostics.
Extrusion Blow Molding
Characteristics & Advantages
Extrusion blow molding allows the realization of complex functional designs and extreme shapes, e.g. containers or reagent cassettes used in diagnostic analyzers. Multilayer technology enables the targeted use of different material layers to achieve a combination of specific properties – for example optimised barrier properties to protect sensitive active ingredients such as veterinary vaccines, but also the integration of functional elements such as transparent viewing strips.
Processing Capabilities
- Materials: PE, PP
- Volumes: 2 ml to 10 l
- Cavities: 2x9
Injection Blow Molding
Characteristics & Advantages
Injection blow molding is an efficient processing method in which a preform is first injection molded and then formed into the end product using the residual heat. In addition to standard plastics (PE, PP, etc.), we also use injection blow molding to process engineering plastics, such as COC or COC, e.g. for highly transparent injection vials.
Advantages of injection blow molding include seamless necks and bases and precise neck shaping of containers that ensures exact fit and sealing of closures. Injection blow molding is also a very low-waste production process which makes it comparably sustainable even at high volumes.
Processing Capabilities
- Materials: PE, PP, PET, COP, COC
- Cavities: up to 20
Stretch Blow Molding
Characteristics & Advantages
Stretch blow molding (also referred to as injection stretch blow molding) is a special form of blow molding. The stretching process at temperatures close to the crystal or glass melting point causes molecular changes that significantly improve the mechanical properties of the material. Stretch blow molding can produce stable containers even with thinner walls compared to other blow molding processes. Stretch blow molded PET containers have a high transparency and surface gloss.
Processing Capabilities
- 4-station technology, allowing for more complex container geometries
- Materials: PET, PP, PC
- Volumes: 10 ml - 500 ml
