From pneumatic screwdrivers to EC servo screwdrivers - reliable and precise

High-tech manufacturer provides optimal screwdriving technology for any application

In order to discover the latest trends in screwdriving technology, I visited the AUTOMATICA trade fair; the leading platform for automation innovations. In Hall A6, Stand 310 at the DEPRAG exhibition stand three slogans caught my eye: “Technical – Clean – Screwdriving – DEPRAG”, “Intelligent – Manual – Assembly – DEPRAG”, “Sheet Metal – Direct – Screw Assembly – DEPRAG”. This seemed to be the right place to get all my questions answered. At the exhibition stand I met Jürgen Hierold, long-standing Sales Manager at DEPRAG SCHULZ GMBH u. CO.

Q: Mr Hierold, can you answer my questions about the latest trends in screw assembly?

A: Yes, you’ve come to the right address. To be able to appreciate the current trends in screw assembly you need also to have an understanding of past innovations and developments. I have been specialising in screwdriving technology and automation since the end of the seventies and so can look back on years of experience. One must also take into consideration, the differences in the development of screwdriving technology on an international level and for example, how in Asia there are different requirements to those in the USA. And in the same way, how the market in the USA was already displaying many trends in the eighties which only later reached Europe and vice versa.

Q: Which specific trend do you mean, can you give me an example?

A: I can well remember the increased demand for fully-automated assembly processes. In order to provide for the increase in quality consciousness, these fully automatic assembly systems were seen as the best option for efficient and reliable manufacturing. Expressed simply, people sometimes make mistakes and their work is not repeatedly accurate (without additional measures been taken). The possibility of using, for example, a robot to minimise errors and increase processing reliability is of course attractive. However despite the advantages of fully-automated processes for processing reliability and efficient production we have learned that a fully-automated system cannot react so flexibly as semi-automatic or manual processes when it comes to short-term changes in factors such as changing numbers of parts.
