Sample Check

Review of pre-production or submitted samples to verify dimensions, materials, plating finish, and mechanical function before production starts.

Production Monitoring

Daily on-site presence to monitor process consistency, identify defects early (e.g., machining error, improper assembly), and ensure corrective actions are implemented.

During Production Inspection (DPI)

Conducted when around 10-30% of production is completed. Key checks include:

  • Assembly precision
  • Surface finish consistency
  • Functionality and part movement
  • Measurement of random units against technical drawings

Pre-Shipment Inspection (PSI)

Final random check on finished and packed goods when 80-100% production is complete. Focus areas:

  • Mechanical performance (movement, strength, torque test)
  • Surface condition and coating
  • Size, weight, labeling, and packaging conformity
  • Functional testing of moving parts or load-bearing areas
