Absolute cleanliness and sterile instruments Sterile containers

The surgical instruments are first sterilized and then packed and stored in appropriate sterile containers. This means that they are always immediately available to the surgeons for quick use in the operating theatre, together with the appropriately configured operating equipment.

High demands

The plastic parts which we manufacture are all made from polyphenylene sulfone (PPSU). This material fulfils the strict requirements which apply to plastic components in medicine in an optimum way. For example, the components must be able to withstand 5,000 cleaning and sterilization cycles in order to make problem-free use in everyday hospital situations possible without loss of functionality.

The right processing

In order to fulfil the demanding requirements, the materials must be processed correctly. This not only requires extremely specialised equipment in the machine park, but it also requires a great deal of plastics processing and toolmaking expertise. This is because the component can only withstand the requirements of 5,000 cleaning and sterilization cycles if it has an internal stress level of (less than) < 5 millipascals (mPa) after production.

If the internal stress level is above 5 mPa, aggressive chemicals such as cleaning or sterilising agents will cause hairline and stress cracks. The result of this damage is that sterilization of the surgical equipment can no longer be carried out successfully.

Our injection moulding tools are specially designed for processing polyphenylene sulfone (PPSU). They can withstand extremely high processing temperatures of up to 390°C and extremely high injection pressures.

In the same way, the entire processing chain, from material drying to material transport and a specially designed injection moulding unit (400°C), is designed for the special requirements.

With our expertise and many years of experience, we provide high-precision solutions which fulfil the high demands which are made in medical technology.
