MEDICAL TECHNOLOGY ASSEMBLY IN SERIES
World market leader for needleless injections. Simon Raidt, Group Leader of Research and Development at Henke-Sass, Wolf, has set himself this ambitious goal for his latest project. The EPIG, a needleless vaccination device for piglets. Such veterinary vaccination systems have been on the market for two decades, including from Henke-Sass, Wolf since 2012. With the EPIG, the developers now want to go one step further. The active ingredient is to be administered to the piglet intramuscularly instead of interdermally. This means that conventional and already authorised vaccines can be used. The drug is injected directly into the muscle under high pressure and without the use of a cannula. For piglets vaccinated with EPIG, this means a gentle injection that can be carried out effectively and with minimal risk.
For Simon Raidt, head of the project, and Thomas Schaz, project purchaser at Henke-Sass, Wolf, this means one thing above all: time pressure and high expectations of the project’s success. The EPIG should stand out from the competition. To this end, battery operation is planned, which is unique in the industry to date. Nevertheless, the end product should be lightweight and thus ensure quick and easy handling, without cumbersome hoses and cables.
Raidt and Schaz turn to HENNgineered: “They offer several processes and so the project could be procured as a complete package.” This advantage should also pay off in the new project. From the final design, through the first prototypes, to the delivery of the veterinary medical technology assembly from the beginning of 2021 with four-digit quantities in series production.
Design manager Michael Stockburger from HENNgineered begins the process with the complete injection moulding design for the EPIG’s housing. Stockburger and his team not only determine the injection points and wall thicknesses for the 2-component injection moulding. They also develop the specified design structure until it is ready for production. In addition to advising on and finding materials, they also ensure that the materials used are certified. The housing should also protect the technology inside from dirt and moisture. Stockburger also finds a solution for this that makes the process simpler and easier to maintain.
