Aus RFIDInnovations wird primtec

Im Laufe der letzen Jahre haben sich im Zuge der Industrie 4.0 viele technischen Neuerungen und Möglichkeiten und daraus viele neue Anforderungen ergeben. Wir haben unser Leistungsportfolio daher beständig erweitert und unser Unternehmen neu aufgestellt.

Um diese inneren Entwicklungen auch nach außen hin sichtbar zu machen, war es an der Zeit, uns einen neuen Gesamtauftritt zu verleihen und so wurde aus RFIDInnovations nun primtec.

RFID technology boosts the fully automatic warehouse at implantcast

Logo implantcast

The company implantcast GmbH is a highly specialized medical technology company, which among other things is active in the areas of development, production and distribution of various prostheses.

At this leading manufacturer of medical implants, Knapp AG’s fully automated warehouse was supplemented with our RFID solutions for incoming and outgoing goods in order to make the previous processes for product identification more efficient.

implantcast GmbH provides hospitals with implants in various sizes and dimensions on a commission basis. Only during the procedure does the surgeon decide which individual product to use for the patient. Because of this, there are a very large number of returns from hospitals. Until now, this was associated with a very high level of effort for chargebacks, as each barcode of each individual product had to be scanned by hand. The invoice was only calculated by the difference in the products consumed.

RFID Arbeitstisch


A solution based on RFID technology was introduced to make the return process and the storage and retrieval of products much more efficient. Each product is clearly marked with an RFID tag, and all workstations are equipped with RFID reading stations. This makes it possible to capture up to 150 products simultaneously at the individual stations in a matter of seconds. Via an interface to the warehouse system, the contents of the shipping carton or small part HU are exchanged with the fully automated warehouse or the customer’s ERP system. Incorrectly associated products or products that do not meet certain criteria (such as best-before date) are immediately displayed to the user and lead to a minimisation of the error rate of up to 100%.

Product labelling

Through tests in our RFID measurement laboratory, we have evaluated the ideal label for the different product groups. All products are subject to the UDI labelling obligation for the unique identification of medical devices – this also had to be taken into account in the coding scheme of the transponders. All newly manufactured products from implantcast are provided with this RFID label during production. The transponders are programmed automatically on the applicator or manually at a TeachIn workstation. This contains a wide range of information such as GTIN, serial number, best before date, etc. From this station, the labelled products are transferred to the fully automated warehouse of KNAPP AG and stored there until ordered.


Incoming goods

The returns with the different, unneeded products from the hospitals accepted and sorted into a marked small part HU. This small part HU is pushed from the workstation directly onto the conveyor system and transported away fully automatically. The uniquely marked products are recorded on our workplace in a matter of seconds and clearly assigned to the small part HU.

Outgoing goods

As soon as an order is received from a hospital, a picking order is created. The small part HUs containing the required products are automatically brought to the picking workstation by shuttles and conveyor technology. There, the required product is removed and placed in the target container belonging to the order. This target container is forwarded to our RFID workplace for packing. There, a target/actual comparison of the products belonging to the order takes place. Correct products are marked in green, wrong products or products that do not fulfil certain criteria, such as best-before date, are marked in red on the screen. This enables an immediate visual check, it can be determined in seconds whether the order is complete and correct.



Buffer station

Since not all orders can be picked by type and in series due to the high product throughput, semi-finished shipping cartons are buffered temporarily. Our software manages the buffer storage bins with the shipping cartons booked on them and the associated shipping orders. If additional target containers for a temporarily buffered order arrive, the location of the associated shipping box is visually highlighted on the screen. This can be removed and further processed at the neighbouring RFID workstation.


Rfid Gate

The completely filled shipping box is taken to the goods issue warehouse and collected there by the shipping service provider. The shipping carton passes through our RFID gate when it enters this warehouse. When driving through, the tags and their direction of movement are detected. If they come into the warehouse, a shipping label is automatically printed for the box; if a product moves in the other direction, back into the warehouse, an automatic chargeback takes place.

„The RFID solution optimally complements the Knapp system and has ensured complete automation of the demanding intralogistics up to the goods issue.“
