Executive Overview

Kirkco engineered an automated epoxy encapsulation architecture for a European manufacturer of high‑reliability connectors used in mission‑critical medical, military, instrumentation, and broadcast applications. The solution replaced a legacy polyurethane process with a higher‑viscosity, environmentally improved epoxy system while increasing consistency, quality, and automation throughput.

Business & Quality Drivers

The customer required vacuum‑sealed and IP68‑rated connectors where performance integrity is non‑negotiable. Failure risk directly impacts safety‑critical systems, driving the need for precise volumetric control, repeatable shot accuracy, and controlled material conditioning.

Process Requirements

The application required six discrete metered shot sizes ranging from approximately 0.07 ml to 0.8 ml. Multiple precision fixtures were integrated to hold connector variants while a three‑axis robotic system positioned the dispensing valve and static mixer for fully automated filling.

Material & Chemistry Considerations

The encapsulant was transitioned from a lower‑viscosity polyurethane to a two‑component epoxy resin with a mix ratio of approximately 100:90. Although more environmentally favorable, the epoxy introduced significantly higher viscosity and tighter thermal stability requirements.

System Architecture

The dispensing platform is based on a precision micro‑metering and mixing system configured for epoxy processing. To maintain process stability, the complete material path is temperature‑controlled, maintaining resin temperature between 50°C and 60°C throughout metering, mixing, and dispensing.

Automation & Controls

The system integrates robotic motion control with synchronized metering, valve actuation, and shot selection logic. This architecture enables rapid program changes across connector variants without mechanical reconfiguration.

Performance Outcomes

The upgraded encapsulation architecture delivered measurable improvements in product quality, shot‑to‑shot consistency, and process repeatability while simultaneously supporting environmental objectives through material selection and waste reduction.

Lifecycle & Engineering Support

Kirkco supported system validation through factory trials, application tuning, and commissioning. Ongoing support includes process optimization, material change evaluation, and automation scalability.

Executive Overview

Kirkco engineered a precision encapsulation architecture to elevate quality, reliability, and repeatability in applications where electronic and electromechanical components must be protected against environmental and operational stressors. The architecture transformed encapsulation from a manual, variable process into a controlled, production-grade operation aligned with long-term performance objectives.

Business & Quality Drivers

Manufacturers of high-value components face increasing pressure to reduce scrap, minimize warranty exposure, and ensure consistent field performance. Variability in manual encapsulation introduced quality risk through inconsistent fill levels, trapped air, and cure variation. A robust encapsulation architecture was required to stabilize quality across operators, shifts, and product variants.

Process Requirements

The application required controlled dispensing of two-component encapsulation materials with precise ratio management, stable material temperature, defined shot volumes, and void-free delivery. Flexibility to support multiple part geometries and encapsulation programs was essential without increasing changeover time or operator complexity.

System Architecture

The encapsulation platform is based on precision metering and mixing equipment configured for epoxy chemistry. The complete material path is temperature-conditioned to maintain viscosity stability and dosing accuracy. Point-of-application mixing minimizes residence time and reduces material waste while ensuring consistent encapsulation quality.

Controls & Validation

A PLC-based control architecture manages ratio control, recipe storage, automated flushing, and process interlocks to prevent off-ratio or off-temperature dispensing. Defined process windows were validated to ensure repeatable encapsulation performance across production runs and component configurations.

Operational Performance

Following implementation, encapsulation quality became uniform and predictable. Scrap and rework were reduced, operator dependency was minimized, and production throughput stabilized. Encapsulation shifted from a quality risk to a controlled and repeatable manufacturing process.

Lifecycle & Scalability

The architecture was designed for long service life with backward-compatible control logic, enabling future material changes, additional recipes, or throughput increases without requiring system replacement. This ensures long-term alignment with evolving product designs.
