I myself have been in pump castings field for nearly ten years. Since my graduation in 2005, i have been dealing with sales work in my first job.My main work is maintaining old foreign customers for regular order's production and shipment. What is more, i need to find new potential customers who are needing castings in different materials. I master English and usually use it to communicate with foreigners in my daily work.Now i can do more in this field. Except sand castings, i can do die-casting, lost wax, lost foam, punching, welding etc.
