Every part undergoes strict NDT inspection before leaving our plant.
OEM & Custom Casting Solutions
Uncovering Valuable Resources
With Precision and Expertise
At Hanhai Casting, we perform professional **Non-Destructive Testing (NDT)** to ensure every casting meets strict international quality standards.
Our inspection covers **ultrasonic testing (UT)**, **magnetic particle inspection (MPI)**, **dimensional measurement**, and **hardness verification**.
Through advanced instruments and skilled technicians, we detect internal defects, surface cracks, and dimensional deviations — ensuring **zero-defect delivery** for critical industrial components.
We apply these NDT methods to all large cast steel, alloy steel, and ductile iron products, meeting or exceeding **ISO 9001 and ISO 14001** requirements.
NDT Process
Ultrasonic Testing (UT)
We use ultrasonic waves to examine internal structure and detect hidden flaws or inclusions within thick castings, ensuring uniform density and soundness.
Magnetic Particle Inspection (MPI)
By magnetizing ferromagnetic materials, surface and near-surface cracks become visible through magnetic particle attraction, guaranteeing surface integrity.
Dimensional & Hardness Verificationy
Precision measuring instruments and portable hardness testers are used to confirm dimensional accuracy and material consistency across all production batches.
Customization - Craftsmanship
Equipped with the world’s leading casting equipment, our company has a strong ability to produce up to 300 tons of products at one time. We have introduced the most advanced testing technology, equipped with OBLF direct reading spectrometer, tensile tester, impact tester, hardness tester and ultrasonic flaw detector to ensure that each product meets the strict quality standards. Our company always adheres to the strict requirements of ISO9001 quality management system and ISO14001 environmental management system certification, setting up an excellent model in the industry.
