11/19: Partners in Innovation & Tradition since 1996 

Klaus Müller GmbH and OTEC Präzisionsfinish

Neuenbürg-based grinding and polishing company Klaus Müller has especially close ties with OTEC Präzisionsfinish. We began discussions in 1996, with the added benefit that our businesses were only a few miles apart. OTEC – which at the time was what we’d now call a startup – was in search of the right compounds for its process development. Klaus Müller had exactly what we were looking for – and still does today. He and OTEC MD Helmut Gegenheimer struck up a partnership that has flourished ever since.In an interview with Klaus’ son, Boris Müller, we discover the key to this successful long-term relationship.

11/19: More security in space

Otec supports Tests for the roduction of new metals

Yes, that is true! Ceramic parts from CeramTec GmbH processed with OTEC precision finish fly around the earth in space  - in a manned space station! How did this happen? The starting point was a research project: as the production of absolutely homogeneous metals on Earth is not possible - the production is subject to physical limits such as gravity - test series were carried out on board the space station, because certain physical limits simply do not apply in space. Here, metal can be melted without contact simply by bringing in energy in limited areas.

11/19: Screw Caps for bottles

High Efficiency and process reliability with polished moulds

The special moulds used for screw caps are usually turned from steel and then milled or injection moulded. In one mechanical post-processing stage (or two depending on the application), the mould is smoothed and polished so that the plastic caps produced on it will separate without sticking or residues, and without affecting the cap geometry. So the smoother the surface, the longer the mould provides top performance.

10/19: Aerospace specialist IFT opts for an OTEC finish:

Quality & accurary in the manufacture of high-precision parts

The exacting safety, precision and quality standards of the aerospace industry are as stringent as it gets. Every single manufacturing step has to be closely monitored and documented. Not every production facility can meet these multi-level requirements. OTEC customer IFT GmbH & Co. KG, based some 30 miles south of Frankfurt in Ober-Ramstadt, specialises in high-precision parts for the motorsport, medical technology and aerospace industries.

10/19: The Special requirements of lasercut parts

Precise, effektive Surface processing

Laser cut parts are used in many industries, from jewellery to automotive, electrical and optical engi-neering. Once manufactured, their edges are slightly burred, and the parts often suffer from unsightly discolouration. Much of the time, these defects are removed by hand, which is time-consuming and costly. The challenge is almost always the same: how to deburr and polish extremely thin parts – i.e. less than 0.4 mm thick and usually made of stainless steel – without changing their geometry. But also, during processing, how to prevent the parts from chafing against each other, or from getting wedged in the container or stuck in the gap.

09/19: Surface Treatment for otoplastics

Best Fitting accuray with otec Precisionfinish

A gentle and effective surface treatment is necessary to prevent the otoplastics from being damaged during post-treatment and to maintain the geometry precisely. Often it is not possible to do completely without manual processing as a preliminary stage for mechanical post-treatment, because internal geometries are sometimes difficult to achieve with automated processes. Effective machining in the OTEC disc finishing machine reduces manual pre- or post-machining to an absolute minimum. This saves time!
Depending on the number of parts and the initial condition, it is possible to vary between different machines, process equipment and running times.

09/19: "Growth through innovation":

from Startup to mediumsized Technology leader (Interview with OTEC Founder)

The company was founded in 1996 by Helmut Gegenheimer and Soran Jota in Straubenhardt, near Pforzheim in the Southern German state of Baden-Württemberg. Since then, as a specialist in surface processing, it has grown from a mechanical engineering startup serving the jewellery and watchmaking industry to a global technology leader in deburring, grinding, smoothing and polishing. Today, international customers from industries as diverse as jewellery and watchmaking, medical devices, pharmaceuticals, automotive and aerospace, electronics, toolmaking and additive manufacturing rely on the expertise we’ve acquired over the course of more than twenty years. Here's an insight into the OTEC Story, with CEO Helmut Gegenheimer.

07/2019: Dental Drills:

OTEC PRODUCES OUTSTANDING RESULTS IN 60 SECONDS

The manufacturing process for stainless steel surgical drills used in minor or major procedures produces burrs. Manual deburring is not just time-consuming but also produces a lot of rejects, not to mention the fact that every drill ends up slightly different. It’s an unreliable process. OTEC SF Series machines are designed for reliable, reproducible precision processing. Drills pose specific challenges.
