Potted Cable Assembly

At Celestix Industries India Pvt. Ltd., we don’t just manufacture components—we engineer complete protection systems for your wiring infrastructure. Our custom potted cable assemblies combine over a decade of specialized manufacturing experience with advanced material science, meticulous design processes, and uncompromising quality control.

In industries like automotive, aerospace, medical, renewable energy, and heavy industrial applications, wiring failure can cause costly downtime, safety hazards, or mission-critical interruptions. That’s why every assembly we produce is purpose-built to safeguard your electrical systems from extreme heat, cold, vibration, moisture, dust, and corrosive agents.

Our assemblies are manufactured entirely in-house, allowing us to control every step from material selection to final inspection. This vertical integration ensures reliability, repeatability, and full compliance with client specifications. Whether your application demands:

  • Extreme vibration resistance in mobile and high-impact machinery

  • Waterproofing to IP69K for submersion and high-pressure wash-down environments

  • High dielectric strength in compact spaces for dense electronic systems

Celestix delivers tailored solutions that consistently exceed expectations.

Inside the Potting Process – From Assessment to Assembly

Our potting process is a carefully engineered, multi-stage approach designed to ensure long-term reliability and peak performance.

1. Initial Consultation & Requirements Gathering

We begin with a collaborative engineering review, understanding every detail of your application. This includes:

  • Environmental mapping of operating conditions (temperature ranges, humidity, chemical exposure, vibration levels).

  • Electrical requirements such as voltage, current, signal integrity, and EMI shielding needs.

  • Mechanical considerations like strain relief points, space constraints, and mounting methods.

2. Risk Assessment & Design Planning

Before we even touch materials, we perform a failure mode analysis to identify potential weak points. This guides our:

  • Selection of potting compound.

  • Conductor and insulation choices.

  • Overmold geometry and strain relief features.

3. Material Selection & Testing

We select the most suitable compound from our tested range:

  • Epoxy – Maximum rigidity, excellent moisture and chemical resistance.

  • Polyurethane – Balanced flexibility, abrasion and impact resistance.

  • Silicone – Outstanding thermal range and UV stability for outdoor and aerospace use.

Each material undergoes:

  • Adhesion testing on multiple substrates.

  • Dielectric strength verification.

  • Thermal cycling from -55°C to +200°C.

  • Compatibility checks with insulation, shielding, and connector materials.

4. Precision Potting & Encapsulation

We use controlled dispensing systems to ensure complete void-free encapsulation. This includes:

  • Vacuum-assisted filling for sensitive assemblies.

  • Layered potting techniques for large or multi-stage designs.

  • Reinforcement for high-stress cable entry points.

5. Curing & Dimensional Stability Checks

Our curing process is monitored to achieve optimal material properties. Post-cure inspections verify:

  • Dimensional conformity.

  • Bond strength.

  • Thermal and mechanical stability.

6. Final Testing & Quality Control

No assembly leaves our facility without full validation, including:

  • Hi-pot and insulation resistance testing.

  • Tensile pull testing.

  • IP-rated ingress protection simulation.

  • Chemical resistance verification.

By following this thorough process, we ensure every potted cable assembly from Celestix not only meets your specifications but outperforms in the environments where it matters most.
