Knowhow Wilhelms GmbH

Being a resident engineer of suppliers with BMW and Daimler plants in Berlin means:

I´m well known inside the maching and assembling plants since 15 Years.

- Always on-site with our clients.
- Quick solutions to problems without going the long way round.
- Better understanding of the clients' specific demands.
- No loss of response time because we know the persons in charge of this company.
- Rapid feedback on the quality of parts supplied by our clients.
- We can react very quick, if a problem came up, sometimes before OEM - Supplier resposibles reacts.
- So our customers has a good status at the OEM.

3D Rapid Prototyping / Rapid Tooling:

Here I would like to introduce a mechanical 5-axis machine that offers universal possibilities.
A new approach: milling robots with rigidity and accuracy of machining centers, also with laser or sand core block.
These machines are also available for machining large cast parts. The special version of the machine can be transported to the workpiece or with a normal truck and is then ready for use within a few hours. Milling of large tools (press or die casting) without disassembly. (ours is not mobile)

Milling of sand cores in the core block process for the production of individual parts / prototyp
Here is the mechanics above and can not be damaged by the sand.
Milling of large plastic models from block material.
Installation space diameter 900 x 400mm

When used with laser:
e.g. Hardening of finished surfaces
e.g. Laser welding for joining attachments.
e.g. for powder build-up welding:
- a thicker anti-corrosion coating
- A layer of another harder wear material
- Tools with "Additive Manufacturing" areas with cooling ducts that the
Follow contour to achieve better cooling
- several variants of a similar basic casting (joining or additive)

We also weld additive with Fronius CMT systems on the robot.

With rotary positioning on the robot, we can coat waves.
Weld hard coating on running surfaces or corrosion layers.
We would like to offer this machine application as a service from 2019 or

If you are interested in having your own machine, make contact and support.

So far we have a plastic 3D printer from Stratasys - Dimension SST 1200es
For Ur models or intuition
Maybe you still have requirements that we do not know yet.

We can offer a 3D Sandprinting machine that is cheaper than the other.

For a building room of  1m x 2m x 1m  the machine costs around 400.000€ 
That is 30% of others.

Including the 3D Sandmilling, we are faster for a mold to cast.
Ask us, we can explain the details.
