Quality Assurance

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, which is critical for developing effective heat treatment processes.

Group 2: Internal Flaw Detection Experts

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 more precise, rapid imaging and sizing of complex internal flaws.

• KARL DEUTSCH Immersion UT Scanner

  • Provides superior coupling stability for high-precision, automated inspections, delivering exceptional results for critical components like bearing rings and mill rolls.

Group 3: Surface & Microscopic Insight

This group is dedicated to detecting surface-level defects and analyzing the material's microstructure, providing a window into the quality of our manufacturing processes.

• Magnetic Particle Inspection (MT) Equipment

  • Detects surface and near-surface cracks in ferromagnetic materials like steel and iron.

• OLYMPUS Metallographic Microscope

  • Reveals the material's microstructural characteristics (e.g., martensite, bainite, grain size), serving as a core tool for judging heat treatment quality and R&D.

• Physical & Chemical Laboratory

  • Supports microscopic analysis by preparing samples through cutting, mounting, grinding, polishing, and etching.

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 3-dimensional geometries and geometric tolerances on machined parts.

• Mahr Contour and Roughness Profiler

  • Measures the contour shape and surface roughness of workpiece surfaces.

Group 5: Process Monitoring & Specialized Testing

We monitor critical process parameters in real-time and conduct product-specific performance validation.

• 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.

• 20,000 KNm Shrink Disc Torque Testing Machine

  • A purpose-built, rare asset that performs specialized testing to validate the ultimate torque transmission capacity and torsional strength of our shrink discs, providing certified performance data that most competitors cannot match.
