Zoomzu automatic molding machine went abroad to help the Vietnamese foundry solve the recruitment problem of manual sanding and improve production efficiency. With excellent product quality and reliable after-sales service, it has won the trust and support of Vietnamese customers in the first equipment. After using it for more than a year, I purchased the second fully automatic molding machine again. After a week of installation and commissioning, the second equipment has been successfully put into mass production. I am also very grateful to Vietnamese customers for their concern and care for the middle casting technician.
