Inex: the precision manufacturing of the smallest components of dental instruments

W&H, a dental precision instrument manufacturer based in Burmoos, is principally engaged in the independent production of mechanical core components. Thanks to modern short lathes and slitting lathes, they can produce small parts with precision and high complexity from bars without much manpower.

Whoever does not value prevention, whoever is sitting in front of the dentist's drill bit will experience the fear and trembling of those creepy high-speed rotating drill bits. W&H, based in Burmoos, Austria, is a leading global manufacturer of dental medical devices, and its researchers are always looking for ways to reduce pain. Although the basic principles of therapeutic instruments have remained almost unchanged for centuries, the innovative optimization of dental heads allows for a more complete mix of air and water, and is suitable for different application purposes, not only more ergonomically, Moreover, it can effectively alleviate the fatigue of the hands and arms of doctors, provide illumination equivalent to white light, and provide more perfect sanitary conditions. For the development of all products, W&H always adheres to the "people-oriented" spirit of innovation, which is also the company's business philosophy.

Small space, high precision: W&H's experts produce precision instrument assemblies for hand-held parts and elbow parts for the dental technology field, which combine high geometric complexity with high demands. Shown in the left and middle figures is a fuel injection orifice plate with a 15° inclined hole and a diameter of 0.4 mm for air-water mixing (jetting) and precision free milling. Shown on the right is a so-called main beam supported by a nickel-silver alloy with grooves and precision threads inside.

Greater innovation pressure

Through the introduction of the above product features, we can see that W&H has a strong competitive advantage in the global market of dental medical devices. Although pharmaceutical technology has long been seen as a growing market worldwide, W&H is still investing in new capacity in the current economic crisis – but it is not without limitations. More and more patients are more willing to replace their teeth with permanent implants in order to avoid expensive treatment costs. In addition, W&H must face tremendous pressure on prices from competitors in Asia.

“But W&H is facing some positive aspects.” Company leader Herbert Schoerghofer summed up the situation. “We are in a business climate that is conducive to innovation, which in turn aggregates above average. The rate of innovation is reflected in the continuous quality and service, reflected in the performance of leading international products, and also reflected in the vertical processing depth of core components."

Rubber Gym Mats are design for continuous, high-impact action. These rubber mats are available in a variety of formats depending on the particular use, layout and permanence of the space. Rubber fitness matting is more resilient than typical rubber matting to be able to stand up to years of constant abuse from weights, aerobic exercise and heavy-duty equipment.
