At Dongbo, we provide more than just exceptional heat treatment processes, our commitment extends to comprehensive precision testing and inspection, ensuring that every heat treatment furnace meets the strictest quality standards.

Our metrology and calibration laboratory are equipped with high-precision instruments, including smooth limit gauges, pointed micrometers, and feeler gauges, guaranteeing dimensional accuracy. In the mechanical testing laboratory, advanced equipment such as shear balances and friction balances allow us to thoroughly evaluate product performance under real-world conditions. In the thermal testing laboratory, we utilize digital temperature controllers and salt spray testing equipment to simulate extreme environments, ensuring environmental adaptability. The chemical laboratory features infrared gas analyzers for carbon monoxide and carbon dioxide, enabling precise material composition analysis.

Additionally, our environmental and reliability testing center conducts high-temperature and humidity resistance tests to verify long-term stability and durability under various conditions. The physical and chemical testing center provides steel and alloy element analysis, flattening tests, and other material evaluations, ensuring that our heat treatment equipment meets stringent performance standards at the core material level.
