POWDER METALLURGY
Sintering
TRENDSETTING INNOVATIONS FOR CO2 REDUCTION
Sintering offers many advantages over customary machining methods. Sintered parts can be flexibly designed, make efficient use of the material and offer extraordinary precision after minor machining in the post-processing phase.
Moulded sintered parts are created from pressed metal powder that obtains its chemical properties during the sintering process.
Brake discs
Casting
PERFECT CASTING TECHNOLOGY
Since 1954 approximately 4 million brake discs have been manufactured by the locations in Tuttlingen and Neuhausen, where roughly 470 staff are employed.
The casting foundry in Tuttlingen produces unprocessed quality brake discs using the grey-casting method. The foundry is a perfect recycling operation – more than 50,000 metric tons of steel scrap are processed into brake discs each year. Extremely high specifications are placed on the scrap. Initially the steel scrap is smelted in a cupola furnace together with coke and thereafter fed into an inductive duplicate furnace that can reproduce the conditions and corresponding elements in the alloy on an article-by-article basis.
A unique selling proposition
At the facility in Neuhausen ob Eck, grey-cast brake discs and composite brake disks are machined and manufactured into ready-to-install components. The aluminium pots for all the lightweight composite brake discs are cast into moulds using a die-casting process.
With its aluminium foundry, SHW is at present the only manufacturer of brake discs worldwide that can cover the entire production chain in-house. As with monobloc brake discs, perfect mill-turning allows particularly close tolerances in production. This constitutes a unique selling proposition of SHW.
In order to meet the high demands of the casting process, all sand cores are coated prior to casting.
This avoids possible sand inclusions in the casting and also has a positive effect on the separation of the mould and the casting and the cooling process of the molten iron.

Machining
Our core competence in machining lies in producing milled and turned parts for oil pumps that meet µ-scale tolerances, right up to finishing on ultra-precision production plants.
With over 20 milling machines for cutting and turning, we are masters at the processes of fine-grinding, brushing and vibratory finishing to produce parts that are completely burr-free and display excellent surface properties. Our internal development operation consists of engineering design, experiments, testing, prototype construction and all other functions needed to develop sophisticated oil pumps completely independently and transfer them to our own serial production.
Close connections to our customers results in a range of pumps, from industrial applications through to aviation, that can be realised at optimal cost.

Automation
The system cycle sets the frequency of serial assembly.
The industrialization of SHW products for the automobile industry is one of our core competencies. Highly-automated machinery and systems ensure the reliability of our products. A fully automated final inspection for function and performance are tested on an end-of-line test bench. Fail-safe systems in the process provide the necessary process and product safety.

Automated assembly
Innovative product solutions
Highly automated and process-monitored assembly and testing systems are used to produce our high-quality products.
All of our high-tech assembly lines are designed specifically for the individual products that are to be incorporated during assembly. The degree of automation of our assembly lines depends on the volumes called up by our customers. With our expertise, we are always able to respond to technological progress and the future requirements of our customers.

Electronics & Software
Embedded electronic solutions
Highly-dynamic electric drives are used to power electric oil pumps used in conventional ICE, hybrid and fully electric powertrains. They are controlled by embedded electronic solutions as well as map-controlled algorithms and are designed for high ambient temperatures and high vibration loads. They typically communicate with other control units via a CAN or LIN bus.
