Here we present a selection of our projects. Working in partnership with companies worldwide is a key part of our philosophy.

Novelty: Needle safety cap

Together with our national and international partners we have developed the needle safety cap for the new Dispojekt Safety Needle from Indian medical device manufacturer HMD (Hindustan Syringes & Medical Devices Ltd.) and British company Star Syringes Ltd. at our site in Jevenstedt, Germany. Meeting the complex requirements of medical technology and automated production underline the success of this innovative development. 

The cap was extensively tested internationally by medical professionals before going into mass production. It proved to be a real asset when handling syringes. During all stages of development, the focus of our product development was on compact, efficient and process-stable injection molding production ensured by the mold components we developed.


We congratulate HMD on the launch of the Dispojekt Safety Needle, which from now on will protect medical staff and patients worldwide from accidental needle sticks and misuse of syringes.


Mask holder KEps


When the pandemic began in early 2020, the shortage of available medical masks quickly became apparent in Germany. With this circumstance in mind, we searched for a way to help. Early on, at a time when homemade masks were the means of choice for self-protection, we made our contribution with the KEps.

The KEps mask holder uses conventional tissues as a filter membrane. This makes it cost-effective, reusable, environmentally friendly and comfortable to wear. The video shows how easy it is to use the KEps mask holder.


In times of crisis with the extent of the Covid-19 pandemic, we see it as our duty as a SME to use our expertise and innovative capacity for the common good and to foster developments.

The stapes is part of the ossicular chain (malleus, incus, stapes) of the human middle ear.


It transmits vibrations generated by sound waves to the inner ear fluid in order to stimulate the sensory cells of the inner ear.

This very important part of the auditory system can fail due to illness, for example, which makes the use of implants necessary.

The stapes is the smallest bone in the human body. We have designed and manufactured a suitable mold for metal injection molding (MIM) and, together with the Fraunhofer Institute for Manufacturing Technology and Advanced Materials (IFAM) in Bremen, have demonstrated our skills and capabilities in the manufacturing of metallic implants.

The constant improvement of our development methods allows us to deal with accurately manufacturing ever smaller structures.


The volume of the component is only 1.25 mm³. After successful further processing, parts with minimal dimensions of 280 µm and a weight of around 9 mg (stainless steel) or 5 mg (titanium).
