Boss Li of Tangshan, Hebei Province, chose five manufacturers as intention before purchasing our factory's sand drying production line. After understanding the price and equipment configuration, he decisively chose Kolev. According to him, he chose us not because of the price, but because the materials used in our sand dryer are better than others, and the structure of the equipment is novel enough to save the cost in production. The factor that allowed him to immediately decide to buy our equipment is that we have many customer cases. A company not far from his factory uses our sand drying machine. He went to see the effect directly and was very satisfied.
