Yingyi has always pursued the service tenet of "survive by quality and develop by credit". Customized products according to customer requirements----customers send the products to the factory for trial operation----conformity testing again before delivery----delivery to your door, and provide one-to-one technical guidance. The machine is tested twice before delivery, and the customer can request to be accompanied by a technician to produce the equipment for 1-2 weeks after receiving the goods to ensure the stable and normal operation of the machine. Customers are comfortable, we are relieved.
