DMH brand turned seals

Thanks to decades of experience and cooperation with our partners, we have continuously developed the machined or turned production of seals. A key factor in our success is our material expertise and our specially manufactured materials. The importance of turned seals is constantly increasing, especially in repair and maintenance. The machining of sealing materials stands for high efficiency through speed and flexibility – without compromising on quality. This makes it possible to reduce downtime, lower maintenance costs, and fulfill customer-specific special requests quickly and economically.

Interesting facts

  • Fact #1

    Through continuous improvement and modern technologies, we have succeeded in significantly increasing the quality of turned seals. Today, turned seals meet the highest standards of dimensional accuracy and quality and offer numerous advantages.

  • Fact #2

    Turned seals are also impressive from a technical standpoint. The surface quality achieved through turning allows lubricating oil to adhere very well to the contact surfaces, ensuring that the seal runs "like clockwork." This reduces friction and extends the service life.

  • Reduced downtime

  • Low tooling costs

  • Small batch sizes from 1 to 100,000 pieces

  • High dimensional accuracy

  • Ideally suited for sample production

  • Oil reservoir in the turning grooves (lubricating film prevents stick-slip effects)

Where do turned seals add value?

Engineering, construction, design, and industry all rely on reliable hydraulic and pneumatic seals, shaft seals, and flat seals. For example, companies in the metal industry trust a wide range of standard and custom-made seals from the DMH brand. The pharmaceutical industry requires special PTFE seals and many individual solutions. DMH brand seals also meet the high hygiene requirements of the food and beverage industry, for example for filling plants.

Trust through quality.
