At room temperature, the Brinell hardness of the casting is ≦300HBW, meeting the requirements of GB/T5680-2023 standard.
At room temperature, the tensile properties and impact properties of the casting meet the requirements of GB/T5680-2023 standard.
Surface Quality:
- The castings are free of cracks, cold shuts, undercuts, slag inclusions, blowholes, shrinkage holes, porosity, and other casting defects that affect performance.
- The castings have undergone mechanical grinding, resulting in a clean surface with no burrs, fins, or sand adherence.
Product Advantages:
- Adopting the lost foam casting process, the surface is smooth and the interior is dense.
- High-quality modifiers are added during pouring, combined with high-frequency vibration to refine grain structure, achieve a dense microstructure, and enhance the strength and wear resistance of the castings.
- The liner plates wear evenly, ensuring stable and reliable quality, eliminating the need for mid-life replacements.
- The lost foam casting process is environmentally friendly, promoting energy conservation and emission reduction.
