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.

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.
High surface quality
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.
Large and small quantities possible
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
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.
Almost tolerance-free production
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
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.

No problem! Contact us!
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.).
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.

Conscientious quality assurance is part of our daily work
and an essential part of the Oesterle DNA. After we serve
customers from a wide variety of industries, we align the
scope and type of quality assurance comprehensively ba-
sed on customer requirements. From the standard inco-
ming goods inspection to the 100% serial in-house X-ray
inspection, we have the right answer to all our customers‘
questions and requirements!
• Cost savings (storage, personnel costs,
administration) and increase in liquidity
• Reduction of throughput times
• Risk minimization (risk of transport, storage and
delivery delay are with us)
