Reliable production Line:
At TIANGONG, each year we invest in production equipment in order to maintain and further improve the high quality of our products.
The only way to achieve required quality is to start with correctly specified material, and process it on the high efficiency forging machinery. In order to ensure the final standard our customers are asking for, proper and precise controlled heat treatment process is the key factor.
Various kind of high-precision machining facilities is also an essential building block to supply highly satisfied products for customers.

On-time delivery and global shipping support
To ensure every forging meets international standards and customer specifications, we have established a comprehensive in-house R&D and testing laboratory. Our experienced quality engineers and metallurgists use advanced equipment to monitor the entire production process — from raw material evaluation to final product inspection.
Spectrometer – For fast and accurate chemical composition analysis of all incoming raw materials
Tensile Testing Machine – To evaluate yield strength, tensile strength, and elongation
Impact Testing Machine – To assess impact toughness, especially for low-temperature or dynamic-load applications
Brinell Hardness Tester – To measure hardness values and ensure heat treatment consistency
Metallographic Microscope – For analyzing microstructure, grain size, and detecting potential defects
Notch Projector – For accurate notch shape measurement in Charpy test samples
Quenching Test Machine – Used to simulate heat treatment response and verify hardenability
High-Precision Flaw Detector (Ultrasonic) – For internal defect inspection according to ISO 4992 / EN 10228 standards.
Every forged component undergoes strict inspection before delivery. Test results are documented and traceable through our quality management system. We provide full ultrasonic inspection records, and mechanical property reports on request.
Combined with our R&D experience, these testing capabilities allow us to:
Develop new forging solutions for wind power, port machinery, industrial gearboxes, and more
Optimize heat treatment processes for maximum performance
Support OEM/ODM projects with technical documentation and trial run data
Guarantee long-term reliability and compliance with ISO 9001, ISO 14001, and ISO 45001
