At HEBEI YOGEM, quality is not just a procedure – it's our commitment to every customer. For over 20 years, we've been producing high-performance cast iron and stainless steel castings for demanding industries worldwide.

 

Backed by ISO 9001-certified quality systems, an independent inspection team, and advanced testing equipment, we ensure every casting delivers precision, durability, and consistent performance.

 

Our Quality Process

01   

 

Raw Material Inspection

We source only certified iron and stainless steel. Every batch undergoes spectrometer analysis to confirm chemical composition, ensuring the strength and corrosion resistance you expect.

Foundry Production

We choose the most suitable process for your product:
Sand casting for large, heavy-duty parts.
Investment casting for fine details and complex geometries.
Pouring temperature, mold conditions, and cooling rates are strictly controlled to avoid defects.

Final Inspection & Documentation

Each casting is visually, dimensionally, and functionally checked before shipment. On request, we provide full documentation:
Chemical composition reports
Mechanical property test results
NDT inspection records(If needed by the customer)
