Wanli has been devoted to introducing, absorbing, applying and re-innovating the technology for more than 10 years. We have 8 ceramic production lines and 4 full-automatic resin coated sand production lines, which guarantee the ceramic proppant's annual output to reach 280,000MT and the resin coated proppant to reach 120,000MT.

Wanli has established a sound QHSE management system according to the ISO, API, and OHSAS standard, which greatly improved our management and operation, and our proppants have passed the tests ofStim-lab, Prop-Tester and Frac-Tech lab, which proved our products have the properties of high temperature resistance, high pressure resistance, high strength and high conductivity.
