Flex Precision Plastics Solutions AG – Cleanroom Planning for Energy‑Efficient Plastics Production

The Swiss company Flex Precision Plastics Solutions AG manufactures highly complex medical products with an above‑average degree of automation in cleanrooms. When the company required additional space to expand its plastics processing plant, IE Plast was brought in due to its long‑standing expertise in Cleanroom Planning. The goal was to dismantle an existing assembly room at the Hägglingen site, redesign it, and equip it with highly automated injection‑molding production cells — meeting both the strict ISO 7 requirements and the highest standards of energy efficiency.

The Challenge

A conventional layout for injection‑molding systems would have required significantly more space and greater room height. This would have necessitated new construction on the Hägglingen site. The chosen compaction approach required all media to be precisely routed to their required positions through the ceiling plenum. New, innovative tools also had to be developed for setting up the injection‑molding technology. Coordinating the ceiling plenum and installing the ceiling equipment presented major challenges for the IE Plast expert team.

Key Success Factors

IE Plast developed a holistic concept for redesigning the plenum ceiling in the production hall. This enabled the required building services to be installed successfully, ensuring that maintenance and inspections remain possible even in tight spaces. Energy and cooling demands were significantly reduced thanks to a scalable cooling and recirculating air system, resulting in substantial gains in energy efficiency. With the extensive experience of our experts and close collaboration with the client and authorities, the time‑critical project was successfully delivered. Quality assurance integrated into the construction planning also played a key role.
