Precision is achieved through a seamless integration of advanced gauging technology,
stringent calibration protocols, a robust inspection system utilizing multiple
intercommunicating measurement techniques, and a dedicated team committed to
accuracy.

Advanced Inspection Methodology

At HALLMARK, we implement a dual-level measurement system to ensure precision and reliability in our quality assurance processes. These complementary methodologies validate each other, reinforcing the
accuracy of our inspections.

• Automated Probe-Type Measurements: Each machine is equipped with contact-type probe measurement inspection equipment, enabling continuous monitoring of individual parameters during production. Measurement data is wirelessly transmitted to the main Data Server, where it is analyzed for Statistical Quality Control (SQC). This analysis generates key insights, including:
  • Dimensional histograms
  • Standard Deviation (σ) process monitoring
  • Machine capability metrics (Cp and Cpk values)

These insights allow for real-time evaluation of production performance, early detection of anomalies, and immediate corrective action to maintain optimal quality standards.

• Automated Laser Micrometer Readings: In addition to in-line probe monitoring, samples from each manufactured lot undergo a secondary inspection using Automated LASER Micrometers.
• Providing submicron precision with a fully automated, contactless measurement system that eliminates human and instrument-related errors. Offering an additional layer of validation and ensure dimensional accuracy and consistency.

This dual-level inspection approach forms the foundation of our stringent quality control system, guaranteeing that every component meets the highest industry standards.

Commitment to Six Sigma Precision

Achieving a throughput of 80,000 pins per day with rejections below 3.4 ppm demands rigorous quality control and a resilient inspection methodology—disciplines that ensure the superior accuracy and consistency vital to every component’s function.
