Protective Enclosure

New protective enclosure completely designed to the customer's requirements

The machine tool manufacturer Kesel looked for a supplier for particularly sealed protective enclosures with short delivery time.

Since Kesel has been cooperating with häwa for many years, when looking for individual control cabinet and enclosure solutions, häwa was also the top address for the FS 1500 bandsaw blade milling machine project. For this project, there was a special challenge: Kesel had problems with the sealing of the protective enclosure of the previous milling machine model. They had problems with water and cooling emulsion leakages, since the seals and the folded edges were unsatisfactorily designed.
Together with the designers of Kesel, häwa redesigned the machine enclosure completely. “Now the protective enclosure is completely tight and clean to the outside, just like our customers wish to have them”, says Björn Natterer, Head of the Kesel Purchasing Department.
All flanged edges and seals are designed in such a way that no processing water and no valuable cooling emulsion can leak out. Natterer stated that a further advantage of the new enclosure is the shortened assembly time. It could be reduced from one week to two days. Owing to the new framework contact with häwa, it was possible to reduce also the delivery time from 14 to 16 weeks to 4 weeks, which eases the business planning of both companies for the current year. 

All at once in two packages
The FS 1500 bandsaw blade milling machine is the first machine which is supplied completely, that means that the internal sheet metal components are delivered together with the protective cover. “häwa immediately agreed and delivers now all required parts in two packages. We do not have to store any enclosure part in our production site. The first package for the protective enclosure assembly is delivered at the beginning of the production of the machine and the second package, including all remaining parts, is delivered according to a precise delivery schedule”, explains Natterer. “The first package for the assembly of the protective enclosure will be supplied at the beginning of the production and the second package, including all remaining parts, will be supplied as requested, according to the assembly schedule, explains“ Natterer. Thus, the assembly sequences are optimized and precisely scheduled. häwa stated that owing to their own transport fleet, they are very flexible in regard to the production logistics. Stefan Kaufer, häwa Debuty Sales Manager for South Germany, commented: “Kesel asked us, if we are able to provide the required parts for the protective enclosure as well as the internal parts at an exact date and in two separate deliveries and we answered them, that we are not here to just sell our products, we are here to do all we can do to satisfy our customers and that this is one of our individual customer service”. Kaufer added: “Your individual requirements are always the focus for us and owing to our experienced consultants, our modern factories as well as our own transport fleet, we are able to realize almost every customer solution on time and cost-effectively.“

More cost-effective than the previous enclosure
Due to the framework contract and the order volume, the new protective enclosure for the FS 1500 bandsaw blade milling machine is more favorable in price than the previous version, although it has been completely redesigned and adapted to the Kesel design and divided in two separate deliveries. Natterer says: “We greatly appreciate that häwa does the very best to fulfill their customer's wishes, if possible. Meanwhile, we have established a long lasting good business relationship“.

The next Kesel machine is in the final construction stage and häwa will once more be the partner for the enclosure construction. Kaufer concludes: “We are in the planning phase and are convinced that we will be able to realize also this project“.
