Challenge

The customer needed a scalable solution for producing multiple variants of 24-pin contact blocks with precise EloPin handling. A key challenge was synchronizing six stamping and bending stations within a 25-second cycle. The system had to ensure high output with 100% inline inspection and sort defective parts by pattern and cavity for traceability.

The HAHN Automation Group delivered a compact, high-speed solution combining flexibility, precision, and seamless integration.

 

Developing a Solution

The manufacturing system by HAHN Automation Group is a fully automated solution producing six variations of electrical connectors. Each variant requires a unique EloPin configuration, with pins stamped, bent, and inserted automatically into the mold. After overmolding, automation performs comprehensive testing of mechanical and electrical integrity.

Compliant parts are tray-packed, stacked, and transferred out, while non-compliant parts are rejected and sorted by cavity and defect type. This detailed sorting supports troubleshooting and process optimization. The integrated system ensures high throughput, consistent quality, and traceable defect handling across all variants.

 

Process Overview

  1. Workpiece carriers on circular conveyor for prestaging contact pins
  2. Synchronized stamping, bending, and inserting of EloPins
  3. Automated part handling in and out of 40-ton IMM with four-cavity mold
  4. Inline testing: high-voltage, contact presence, and pin position checks
  5. Tray packaging system with automatic stacking and sorting for defects

Cycle time: 25 seconds per part.

Results

The HAHN Automation solution improved efficiency and traceability, producing 576 parts per hour with a 25-second cycle. The compact 65 m² line handles six variants with precise control and integrated testing. Automated defect sorting boosts transparency and reduces downtime, providing a future-ready, fully automated system.
