The Company is engaged in the research and development of high activity silver powder for solar electronic paste; sales of photovoltaic materials. Due to the special production process, the mixing equipment was imported from abroad, which was expensive and could not keep up with the service. Before also spent a lot of energy in the domestic search for alternative imported mixing equipment, but has not found the ideal. By chance, the manager of R&D department, Mr. Lu, saw us on the internet. After half a month of communication and efforts between Lu and our technical department, the final solution was determined to meet the customer's needs, and we also learned valuable experience from it.
