| The QT700 series castings are mainly produced using the sand coating process - iron mold sand coating< br> Characteristics of film coated sand process:< br> 1. The design is convenient and fast, with less sand usage and high surface smoothness and dimensional accuracy of the castings< br> 2. Iron sand box - high rigidity, capable of achieving riser free (self shrinking) casting. Fast cooling and dense product organization< br> 3. The hardness is about 20HB higher than that of ordinary casting, which is particularly advantageous for producing high-grade pearlite matrix disc and shaft ductile iron castings< br> 4. Suitable for small and medium-sized products with large production batches or high quality requirements    On site quality control   |
