2 OESTERLE GMBH

This promise has been kept since OESTERLE® was founded in 2004 by Dipl. Ing. Hermann Oesterle, with the support of his wife Mrs. Brigitte Oesterle. The focus at that time was in the area of MIM and investment casting. Over the past years, business relationships have been successfully established and expanded across Asia and Europe. Today OESTERLE ® is one authorized strategic supplier of many worldwide global industrial companies. Our strengths are constant process development and the best implemen- tation of highest requirements - for safe, highly economical and future- oriented parts made of metal and plastic.

Metal Injection Molding (MIM) is based on the principle of injection molding, which is the undisputed number one in the series production of plastic com- ponents. MIM combines the advantages of injection molding with the material properties of metals. By mixing metal powder with a plastic binder, the advantages of the injection process can also be used for metal components. The binder wets the metal powder particles and enables shaping. The binder is subsequently removed and the metal powder is sintered in a vacuum furnace below the melting tem- perature, thereby shrinking to its final size and achieving its high strength and resilience, which are largely comparable to the solid metal material. Due to the use of different metal powders, there are nearly no restrictions in the choice of alloy. Assemblies can often be combined into one part. MIM is the right choice for complex, efficient, fast, environmentally friendly and accurate parts with high surface quality.

Investment casting

The precision casting (investment casting) production technique is the optimal choice for complex components of almost all sizes. The advantage of the pro- cess is, among other things, that parts from smaller batch sizes can usually be cast ready for installation with manageable tool costs and often require little or no mechanical post-processing. Castings produced by investment casting, especially by lost wax process, are characterized by their level of detail, dimensional accuracy and surface quality and can therefore also meet the highest customised requirements from a wide variety of industries. Parts with a typical weight of approx. 30 g up to 200 kg can be produced by investment casting, and a wide variety of materials from steel to aluminium or titanium can be processed.

Advantages Surface quality Dimensional accuracy Material selection Large and small quantities possible

Machining Machining as a manufacturing process for metallic components can be used for all workpieces, but especially for complex requi- rements. With no lead time for tools, machining enables fast and stable production. The start-up costs are lower compared to other manufacturing processes (e.g., die casting, MIM), so that smaller series and pro- totypes with tight tolerances can also be manufactured, but often with high economic costs.

Advantages Almost tolerance-free production Low quantities No tool costs

With the diecasting process, high precision components from low-mel- ting alloys such as aluminium, zinc and magnesium can be manufac- tured with very high surface qualities. The process is economically worthwhile, especially for large series. In die casting, the liquid metal is shot through a piston into a divided permanent mold. The sometimes very high pressure loads also allow very thin-walled and complex components without loss of quality. Even with large parts, the mold is filled in fractions of a second, resulting in short cycle times. If the series size is sufficient, die casting is a highly economical casting process.

Sintering

Sintering as a manufacturing process for metallic components is the right choice for workpieces with special geometries, such as compact gear wheels, pinions, bearings or housings, which can be produced ready for installation (also with heat treatment). Sintering allows shaping without heating the material. The metal powder is pressed into green compacts in matrices at different pressures and sintered in a further step at temperatures just below the melting point. The powder partic- les melt together at their contact surfaces and the workpiece gets its dimension and design. Due to a final calibration impact, the workpieces have a very high level of dimensional accuracy. The process is therefore an effective, environmentally friendly and economical process, especially for large quantities.

CNC processing

The requirements for components vary greatly depending on the respective fields of application and specific tasks. In most cases, a high degree of tolerance accuracy, attention to detail and surface quality is required, but often only in certain (functional) areas of the component. For these cases, we offer a wide range of post machin- ing processes, also for special requirements, and can process the components precisely. You get the perfect symbiosis of achievable precision and maximum economy.

Heat treatment

Subsequent heat treatment can be used to adjust the technological properties of materials. The component to be treated passes through various controlled temperatures at different times (temperature-time profile) and is then cooled at different rates in certain media, depending on the material and process.

Surface finishing

We have many technical processes at our disposal to refine the component surfaces, which can improve the surface properties. Both the functional properties of the component can be impro-ved (e.g., higher wear and tear protection, corrosion protection, prevention of contamination) and the decorative properties (e.g., through colour changes, gloss levels or similar). Our portfolio ran- ges from treatments such as pickling, blasting or impregnation, galvanizing, nickel plating, powder coating, CDP coating, laser marking to hard material coatings (physical vapor deposition, etc.).

Assembly

Numerous manufacturers use ready-to-install assemblies and pro- ducts. Outsourcing has a multitude of advantages for companies. Economic assembly production relieves the customer‘s resources. The products are manufactured individually for the customer accor- ding to specific specifications. Partial quantities are also possible. This service is also part of our portfolio and is already being used by many our customers, for example in the automotive industry.
