WSW – 3D Prototype Plastic Printing

After searching for a long time for a 3D printer which was optimal for our range of sizes, in April this year we decided to invest in a Raise 3D 2N Plus. With an installation size of 300x300x600mm we are now able to print practically all the forgings produced at our company, whether to scale or on a scale of 1:1 by means of joints. In addition the Raise 3D 2N Plus has a dual extruder for picking up water-soluble plastics, which also means that complex geometries can be produced. This results in several advantages for our customers. On the one hand we can already produce samples in the engineering phase in order to compare and test installation situations with CAD models. On the other hand the throughput time of drop forges which are mechanically processed is optimised so that the printed model can already be used by external service providers for setting up the machines before the actual start of production.

WSW – Laser hardening of cuts – a new process

Deburring tools produced at our company, which consist of the so-called “deburring cut” und “trimming punch”, are produced from unalloyed tool steel (1.1730) with good machining properties and an approximate strength of 400 MPa. Until 2015 in order to increase the strength to >1.500 MPa the cuts were pre-heated in follow-up processes and the cutting edges were welded and then re-milled according to specifications. In a 3-year testing phase we were able to replace this expensive process by one which is much more cost-effective for us: “Laser hardening” at Wilhelm Alte GmbH in Plettenberg. This so-called laser hardening is one of the surface hardening processes along with flame and induction hardening and can be used for hardening practically all common steels, which would otherwise be annealed conventionally. The 1.1730 which we
use also achieves clearly improved properties in the cutting edge area (approx. 10x10 mm). In our case this also resulted in a throughput time shortened by 1 to 2 days while at the same time reducing our costs to guarantee our competitiveness.

WSW - We aim for the highest quality!

Our customers make stringent demands on us and we want to continue to meet those requirements! Downstream surface crack detection in the forging and heat treating processes is a testing procedure to identify surface faults. Providing this complies with the applicable standards as well as customers’ specifications, we then correct the faults and define corrective measures. Recently, regardless of which sector is concerned, the requirements of this testing procedure have been increasing constantly. In order for us to remain the drop forgers you trust and to enable us to continue to test and vouch for the highest quality standards, we have invested in a more modern crack depth gauge. This allows us to examine ore closely information discovered during the MT testing and to determine the crack depth by means of the electronic resistance between two points. By using the new gauge we have already been able to significantly optimise our sub-processes – for instance construction parts shown to have cracks hich are “too deep” can be removed from the current process straight away, thus eliminating manual adjustment and further testing of those parts. Similarly our new crack detection gauge is extremely useful for our colleagues in the tool making department to enable them to test and analyse immediately any cracks (due to wear) occurring in production. The instrument also helps with determining surface faults in the raw material, as it is far easier to provide evidence for claims made against suppliers. We are thinking ahead. Owing to the excellent practicability of the instrument nd the positive speeding up processes resulting from it further investment is planned.

WSW – Expansion investment in tool making

In May this year we began investing in an additional machining centre, a Makino F9 with Makino Professional 5 (FANUC) control. As far as tool making is concerned this represents an optimal extension to the Makino a82 currently in use, whose pallet load capacity is limited to 1.5 tons. Some background information: Thanks to a Simufact forging simulation, which we have been using since 2014, we have succeeded over and over again in increasing production levels for our forgings. Currently, depending on the geometry, we can
reach component lengths of up to 1,370mm with an operating weight of 125kg. This resulted in considerably larger and therefore heavier tools and dies with upper and lower parts, each weighing more than 2.5 tons and also to general bottlenecks in our tool making, where we sometimes had to outsource. After the foundations have been built in January 2018 the machining centre is scheduled to make the first chip.

We would like to take the opportunity to let you know about the new dual leadership in our company.

After Mr Roland Newe left our company on June 15th 2017 at his own request in order to take up a new position with a former employer, the Mendritzki-Group, Mr Philipp-André Klever temporarily took over as the sole managing director. As from October 1st 2017 he will now be joined by Mr Cengiz Tezsoy, who will begin his new position as technical managing director of our company.

Herr Tezsoy is married, has two children, is a graduate engineer and has over 15 years’ experience in technical fields of the forging industry.
Together with Mr Klever, who has been with the Prange Group and WSW since 2013, Mr Tezsoy views the future with confidence and is looking forward both to the new challenge and to having the opportunity to meet you personally.

WSW – 60 years of forge knowhow from Plettenberg, how it all began…

Schulte-Wiese senior first began his career as a die maker in a company in this region and later worked himself up to be the plant manager and the production manager until finally as a partner he steered the fortunes of the company. In that era Plettenberg and particularly Himmelmert was predestined for the metal-processing industry due to its geographical position and its access to hydropower. Then in 1957 the day arrived when he started production at his own plant at the gates of the Ruhr area – initially mainly for the mining and mechanical engineering industries. Over the years the company also became a supplier for sophisticated and safety related drop forgings for the automobile, commercial vehicle and railway industries under the son, Dr. Hartmut Schulte-Wiese. Since 2013 Schulte-Wiese has been part of the privately led Plettenberger Prange Gruppe, whose strategy is based on long-term stakes in companies with strong ties to the region. But since 1957 we have not lost sight of our roots, as some 30% of Schulte-Wiese’s turnover is still generated by the international mining industry to as far away as China, Australia, South Africa or even the USA. In the railway sector nowadays drop forgings are used particularly in highly sensitive areas in coupling technology or bogies from our company. If you take the family out into the countryside in your car and take your bicycle too, fixed on a bicycle carrier mounted on a so-called ball neck, you could well be travelling with a forging from Plettenberg-Himmelmert. The use of forgings in comparison to generative manufacturing processes or additive manufacturing, (AM for short) is indispensable and in the long run they will prove themselves.

WSW – In use again all along the line

In order to be able to meet our customers’ increasing requirements regarding the cost effective production of components of various geometries and batch sizes we have gradually expanded, adapted and modernised our 8-ton forge line. Our aim here is to create a design for our customers’ ideas by means of preforming steps saving resources as far as possible and with a reduced amount of burr. In 2015, we already extended our production line of induction furnace, 8-ton Lasco forging hammer and Heuser trimming press to include a Banning pre-form press for bending operations and an Eumuco forging roll to minimise the amount of material required. In January 2017 in cooperation with our maintenance team, our service provider overhauled our whole forging unit substantially and provided it with a new Jerko spraying system. The latter contributes not only to a reduction in the use of sawdust as a release agent, resulting in cleaner surfaces, but also to an increase in the tool life of the dies. The changes made over the past two years have equipped us better to fulfil the requirements of medium sized series up to
approximately 100,000 parts per year, without losing the flexibility needed for smaller batch sizes.
