Quality Assurance

Unmatched Quality Assurance: From Material to Measurement

At Liaoyuan, our commitment to quality is underpinned by an in-house inspection capability that ranks among the most comprehensive in the industry. While many competitors rely on third-party testing, we invest in advanced technology to monitor and validate every critical stage under one roof. This direct control ensures the highest standards of performance and reliability while guaranteeing faster turnaround and absolute data integrity for our clients.

Group 1: Material Foundation Certification

This suite of equipment validates the very essence of our raw materials—their chemical composition and fundamental mechanical properties.

• OLYMPUS XRF Spectrometer
  Determines the chemical composition of materials to ensure the correct grade of alloy steel and other metals are used.
• Universal Testing Machine
  Measures key mechanical properties including tensile strength, yield strength, and elongation through tensile, compression, and bend tests.
• Impact Testing Machine
  Evaluates material toughness (impact energy) under high-velocity impact, crucial for assessing performance in low-temperature or harsh environments.
• Automatic Jominy Testing Machine
  Conducts Jominy end-quench tests, the standard method for determining steel hardenability, critical for developing effective heat treatment processes.

Group 2: Internal Integrity Verification – From Macro to Micro

We employ a range of non-destructive testing (NDT) technologies to ensure structural integrity by detecting internal imperfections without damaging the component.

• Ultrasonic Flaw Detector
  Uses high-frequency sound waves to detect internal defects such as inclusions, porosity, and cracks.
• OLYMPUS PAUT (Phased Array Ultrasonic Testing) Device
  Employs advanced Phased Array Ultrasonic Technology for precise, rapid imaging and sizing of complex internal flaws.
• KARL DEUTSCH Immersion UT Scanner
  Provides superior coupling stability for high-precision, automated inspections—ideal for critical components like bearing rings and mill rolls.
• OLYMPUS Metallographic Microscope
  Reveals material microstructure (e.g., martensite, bainite, grain size), essential for verifying heat treatment quality and supporting R&D.

Group 3: Surface & Microscopic Insight

This group focuses on detecting surface-level defects and analyzing material microstructure, providing insight into our manufacturing quality.

• Magnetic Particle Inspection (MT) Equipment
  Detects surface and near-surface cracks in ferromagnetic materials like steel and iron.

Group 4: Precision Dimensional & Geometric Verification

Post-machining, we verify that every dimension, form, and positional tolerance meets the exacting specifications of the design.

• Wenzel CMM (Coordinate Measuring Machine)
  The ultimate authority for precise measurement of complex 3D geometries and geometric tolerances on machined parts.
• Mahr Contour and Roughness Profiler
  Measures contour shape and surface roughness of workpiece surfaces for precision surface finish verification.

Group 5: Process Monitoring & Specialized Testing

We monitor critical process parameters in real-time and conduct product-specific performance validation to ensure consistent production quality.

• Portable Infrared Thermometer
  Provides remote, non-contact monitoring of real-time workpiece temperature during forging and heat treatment, ensuring process accuracy.
• Rockwell & Leeb Hardness Testers
  Measure material hardness to verify heat treatment results. Rockwell for high-accuracy lab use; Leeb for portable, rapid testing on large components.

Group 6: Design Validation & Proof Testing

• 20,000 kNm Shrink Disc Torque Testing Machine
  This purpose-built, rare asset is where our designs meet their ultimate proof. It performs destructive testing to validate the maximum torque transmission capacity and torsional strength of our shrink discs, generating certified performance data that provides unparalleled confidence in your design choices and sets us apart from the competition.
