▶ ISO 9001:2015 

We achieved certification to ISO-9001-2015. With help of the quality management systems, we standardized our production process, and made the quality stable while reducing the costs.

  

▶ Raw Material Inspection 

Incoming raw material were kept in control strictly, because we believe raw material in good quality is the foundation of the high quality of the castings and finished products.

All the raw material like wax, water glass, aluminium, iron, steel, chromium etc are bought from the certificated manufacturers stably. Product quality documentations and inspection reports must be provided by the supplier, and inspection will be implemented strictly during the materials’ arrival.

  

▶ Computer Simulation 

Simulation programs tools (CAD, Solidworks, PreCast) are used to make the engineering works of casting more predictable to eliminate the defects and improve the stability before real manufacturing. 

 

▶ Chemical Composition Testing 

Chemical composition analysis to the castings is required. Specimen will be taken and tested both pre-pouring and post-pouring to control the chemical composition within the specification, and the results must be doubled checked again by the third inspectors. 

The specimens being tested also are kept well for at least two years for tracking using. Heat numbers including the time and temperature can be made to keep the traceability of the steel castings. The Spectrometer and Carbon Sulfur analyzer are the main equipment for the chemical composition testing.
