The Main Benefits

  1. High level of protection against moisture, dust, and dirt
  2. Protection against chemicals and corrosive environmental influences
  3. Significant increase in mechanical stability
  4. Reduction of vibrations and noise
  5. Protection against wire movement and insulation damage
  6. Improved electrical insulation and dielectric strength
  7. Longer service life and greater operational reliability
  8. Tamper-proof and touch protection

Vacuum Encapsulation

In vacuum potting, the assembly is potted under a vacuum. This virtually eliminates air bubbles and voids. The potting compound can penetrate deep into windings and gaps, resulting in particularly homogeneous and reliable insulation.


Advantages of vacuum potting:

  1. nearly bubble-free potting structure
  2. improved heat transfer
  3. higher electrical dielectric strength
  4. increased long-term stability
  5. Optimal penetration of complex winding structures
  6. Greater process reliability and reproducibility

As standard, we use the Huntsman Arathane CW5631 polyurethane casting system in combination with the HY5610 hardener. This system offers a very balanced combination of electrical, mechanical, and thermal properties and is suitable for a wide range of industrial applications.

It is particularly distinguished by the following features:

  1. Very good electrical insulation properties
  2. Good thermal conductivity combined with elastic behavior
  3. low shrinkage during curing
  4. High adhesion to metals, plastics, and windings
  5. Good vibration and shock resistance
  6. Reliable protection against moisture and environmental influences
  7. Good long-term stability

The potting compound is processed fully automatically and applied under vacuum. This results in reproducible, high-quality potting results with high process reliability, even for complex wound components or sensitive parts.

Depending on the application, alternative potting materials can be used.

Encapsulants with lower Shore hardness

Softer potting systems have greater elasticity and better damping properties. They are particularly suitable for:

  1. severe temperature fluctuations
  2. sensitive components
  3. Applications involving movement or expansion
  4. vibration-sensitive systems
  5. High-strength potting compounds

For extreme mechanical stresses, high-strength systems with increased compressive and impact resistance are used. These are used in:

  1. severe shock and vibration loads
  2. Applications with high mechanical stress
  3. Operating conditions involving forces up to many times the acceleration due to gravity
  4. Rail, aviation, or military technology
  5. high-performance industrial drives

Silicone Encapsulation

Silicone-based potting compounds offer high flexibility and excellent resistance to thermal cycling. Typical advantages:

  1. very wide temperature range
  2. high elasticity
  3. low stress transfer to components
  4. good aging and UV resistance

They are frequently used in automotive, outdoor, or high-temperature applications.
