CERAMIC SOLUTIONS. FROM A SINGLE SOURCE.

Are you looking for ceramic solutions from a single source? An expert in the area of shaping material loss processes for small and micro ceramic parts, Heberlein supports customers from the concept to distribution. The company’s main focus is on selecting appropriate materials and substituting existing metal or plastic components. In addition to the precision machining of oxide and non-oxide ceramic materials in prototyping and in series production, tailored solutions for subsequent process steps complement our catalogue of services.

Key technical data. We manufacture with precision.

Key technical data

The cutting-edge machinery designed for small and micro parts includes circular and coordinate grinders with up to five axles.

  • Workpieces of 1 to 100 mm space diagonal (rotary and cubic)
  • Production tolerances as small as ±1.5 μm
  • Production of prototypes and small to medium-sized series
  • Series production
  • Contract production

 

Materials. And your attributes.

The term «high-performance ceramics» refers to ceramic materials whose features are well suited to use in technical and medical applications.

  • Green and white machining
  • Materials for hard machining
  • Aluminium oxide Al2O3 (99.7%, ZTA )
  • Zirkonium oxide ZrO2 (TZP , ATZ , bioceramics)
  • Silicium nitride Si3N4
  • Silicium carbide SiC
  • others such as B4C on request

Aluminium oxide (Al2O3)

Aluminium oxides are the most widespread raw materials used in high-performance ceramics.

Zirconium oxide (ZrO2)

Its outstanding features are derived from the addition of stabilisers such as magnesium oxide and yttrium oxide. Zirconium oxide has a fine crystalline structure. It can withstand extreme bending loads of up to 2,000 MPa.

Silicon nitride (Si3N4)

Silicon nitride is ideal for producing components able to withstand a mechnical load. Its strength remains even at high temperatures.

Silicon carbide (SiC)

Silicon carbide has very high thermal conductivity and a high level of hardness. It also has excellent anti-friction properties. Its strength remains even at high temperatures.

Precision machining

Our infrastructure allows us to machine medium-sized series. Thanks to a high level of precision, we are even able to meet the μ production tolerances required in the watchmaking industry.

Our catalogue of services includes the following machining steps:

  • Sintering during ceramic production
  • Abrasive shaping processes such as green and white machining or hard machining
  • Surface finishing processes such as honing, priming/remaining, laser-cutting/labelling, lapping, grinding,
  • cauterising, and sandblasting

 

Quality control

Quality control encompasses the following services:

  • Optical measurements
  • Tactile 3D measurements
  • Roughness measurements
  • Crack testing
  • Microsections
