Selective for the 1,111th time!

“During discussions with the Ersa sales engineer responsible, we quickly settled on the VERSAFLOW 3/45, which is identical to the selective system we purchased in 2015, except for the jubilee sticker and a new PC or new software. Both of our systems are calibrated to one another, the programs are opened separately by each machine via a central server – if a change is made, this is done once and both systems react synchronously to it,” explains Michael Hannusch, Head of Processes and Technologies (Head of Processes and Engineering). This means the Hannusch team can simply switch from one job to the next, without major conversion and retooling being necessary – a major advantage, since the Swabians have to handle a lot of batch sizes between 50 and 100, sometimes even only between five and ten pieces.

The jubilee machine, on the other hand, is used especially for a customised process with 1,000 pieces – with a good 5,000 complex assemblies being produced. Product carriers are loaded manually and supplied to the machine, which processes them automatically. The product concerned is a high-quality bicycle light with an illumination level on a par with that of a modern motorcycle headlight. “The second VERSAFLOW 3/45 was more of a gut decision initially, because the order for the lighting was in the cards but not confirmed at the time – at the end of the day it was placed at the optimum time and we can produce without rework and access the program centrally on the server, which enables us to achieve reproducible top quality again and again,” says a delighted Michael Hannusch. The process engineer was particularly impressed by features such as the reactivation of the nozzles and inspection of nozzle height which was not available in the same way in comparable machines – while the insensitivity and low maintenance effort required for the system were just as impressive. The Hannusch team went to Wertheim for the preliminary acceptance test, but decided against putting the system through its paces at the demonstration and application centre. After all, they knew from their experience with the VERSAFLOW 3/45 purchased in 2015 what the selective system is capable of.

Following preliminary acceptance, the installation itself went as smoothly as usual – tailor-made Ersa all-round service with fast response times, which include the speedy supply of any spare parts required, valued by Hannusch Industrieelektronik for more than 30 years now. Thanks to the high Ersa share in the Hannusch machine park, the operators did not require a lot of training and were able to ramp up productivity on their second VERSAFLOW 3/45 directly. The two selective systems are only two steps apart in production, so that the machine operator can always keep an eye on both systems. Alongside the heating above the line, soldering wire feed and a pot, one of the main features of the 1,111th VERSAFLOW 3/45 is the ERSASOFT 5 operating software with modern visualisation and user-oriented structure: individual interfaces show every operator group the data and information required directly. The new interface is convenient in terms of process monitoring, too – modern picture-in-picture technology (PIP) provides a free view of soldering parameters and a live process picture for optimum control during every soldering process. Conclusion: The 55-strong team at Hannusch is extremely well equipped with Ersa soldering systems at the moment. Even if the current Managing Director Claudia Hannusch will be handing over the company reins to her son Michael in the mid-term – this will not change the cooperative business partnership between the two companies. And if soldering systems should be required at any time in the future, quick and direct contact between Laichingen and Wertheim am Main will achieve a feasible solution in no time!
