Quality & Validation Testing

End of Line – Leak & Performance Testing

Dedicated End-of-Line testing station for automotive brake system pumps – delivering precision differential leak testing and hydraulic performance verification.

Project Overview

Critical Leakage & Pressure Validation for Brake Pumps

The End of Line (EOL) Leak & Performance Testing Station is an indispensable quality gate built by Tri-Dot Solution for automotive brake system pumps. Brake pumps operate under critical hydraulic pressures where any micro-leak or pressure drop directly threatens vehicle safety.

The system incorporates an ergonomic Sliding Arrangement for effortless component loading, a rugged Component Holding Fixture with quick-sealing pneumatic connectors, and a digital Differential Pressure Leak Tester.

Within a complete test cycle of 2 minutes per component, the machine executes chamber filling, stabilization, high-precision leak measurement, pressure holding verification, and automatic part marking.

Engineering Elements

Testing Architecture & Subsystems

Precision Leak Tester Unit

High-sensitivity differential pressure decay instrument capable of detecting micro-leaks (sccm/Pa) with high accuracy.

  • Multi-channel pressure evaluation
  • Temperature compensation
  • Real-time graph & data logging

Ergonomic Sliding Table

Heavy-duty linear sliding bed allows safe, open-access operator loading followed by smooth pneumatic positioning into test chamber.

  • Smooth linear bearing guide
  • Dual safety position interlocks
  • Anti-pinch protective design

Pneumatic Clamping & Sealing

Specially engineered hydraulic/pneumatic clamping cylinders actuate polyurethane seals directly over pump ports.

  • Zero-leak sealing connectors
  • High clamping force without distortion
  • Seal wear detection feedback

Performance Testing Cycle

Tests internal pump relief pressure, check-valve performance, and displacement characteristics under simulated operating load.

  • High & low pressure verification
  • Flow rate and backpressure check
  • Fail-safe automatic venting

Automatic OK / NOK Marking

Integrated dot-peen or ink-marking head marks verified OK components with date/batch code; NOK parts are auto-locked.

  • Positive physical marking
  • Rejection bin lock until operator reset
  • Complete traceability record

Industrial PC / HMI Interface

Complete computerized test report generation with barcode scanning, SCADA export, and statistical quality control (Cp, Cpk).

  • Barcode traceability integration
  • Ethernet/USB test report export
  • Multi-level password security
