Parker extends cleanroom cell capabilities at Praedifa plant in the Czech Republic

For elastomer and plastic components for the medical and pharmaceutical industries

Parker Hannifin, a leading supplier of motion and control technologies, has followed the launch of an ultra-modern cleanroom cell at its Czech location in Sadská, with the extension of its capabilities to meet the demands of the medical and pharmaceutical industries. The operation is focused on manufacturing bespoke solutions made up of elastomer and plastic components developed at German locations in Pleidelsheim and Bietigheim.

The 130m2 GMP cleanroom cell currently consists of several ISO 7 to ISO 9 cleanrooms and has been designed to allow quick-and-easy extension of the facility as needed. A collection of manufacturing cells exclusively dedicated to custom products is also possible.

State-of-the-art injection moulding technology to process a range of materials such as silicones (LSR and HCR), TPE and other elastomers is the centrepiece of the cell. Two-component solutions (such as silicone/plastic or TPE/plastic) in cleanroom Class 8 are also possible.

A new micro-injection moulding machine in the Class 7 cleanroom is available for manufacturing high-precision, particle-free moulded parts and seals as well as processing high-transparency liquid silicones.

Advanced over-moulding technology for single-use systems is available as an alternative to conventional cable ties. This technology primarily serves to combine silicone and TPE tubes with other plastic components, such as aseptic connectors, filters or transport containers, or various tubes with each other. Due to the lower risk of leakage compared with cable ties, over-moulding is suitable for assembling products intended for use in critical process areas.

As well as conventional bonding or gluing, ultrasonic welding work is performed in a Class 7 cleanroom. The significant advantages of this method are high reproducibility and the elimination of the use of additives, which benefits the purity of the product. PTFE or PES diaphragms can be securely and reliably affixed to plastic components. Ultrasonic welding is mainly used in the assembly of products for clinical use in the area of infusion therapies.

For quality assurance Parker-Prädifa uses state-of-the-art inspection and testing technology that meets the exacting safety requirements of the medical and pharmaceutical industry as well as the needs for cost efficiency and economy. Various packaging options are available for products manufactured in the cleanroom cell, ranging from simple PE bags and PETG single blisters with Tyvek covers to moulded pallets.
