Pump segments

Pump segments are used for the administration of medication or liquid nutrition in dosing pumps. Next to a constant flow rate, there are more functions that can be integrated into the device, such as a membrane for pressure monitoring.

Silicone Plugs

Silicone plugs are applied in pre-filled syringe systems in order to guarantee the integrity of the drug. Enjoy the benefits of an integral adjustment to your syringe system. Due to the selection of the optimal silicone type, the silicone plug shows only minimal breakaway forces and dynamic frictional forces, as well as no stick-slip effect at all.

Thin Walled Components

Thin walled components with smallest wall thicknesses of down to 0.10 mm are applied in inhalation systems for the transportation of aerosols, for example. The fixing elements tailored to your system are directly overmolded in order to enable a form-fitting and friction-locked integration.

Sealing Elements

In the medical and pharmaceutical industry silicone seals are applied in injection and infusion systems, for example. They preserve the integrity of the drug in primary packaging. The sealing elements are tailormade to suit your system with regards to torque, tolerance compensation, insertion forces, pull-off forces, spring forces and restoring forces as well as the ventilation of your system.
