The general manager of Costa Rica Industrial Equilab S.A came to our company for business negotiations. The two parties formally signed a contract for the supply of 1 t/h washing powder equipment. The foreign party requires the production device to be able to produce finished washing powder with an apparent specific gravity of about 0.20. Our company adopts special technology to fully meet this requirement. Since then, Mr. Xiang of our company accompanied the guests to visit other detergent production facilities of our company.
