Qinhuangdao Pengyi Intelligent Technology Co., Ltd. (formerly known as Qinhuangdao Pengyi Chemical Machinery Co., Ltd.) is a modern equipment manufacturing enterprise that integrates scientific research, design, production, sales, and service. Built on the foundation of "intelligent machines + intelligent systems," the company specializes in the R&D, production, and sales of complete sets of equipment for wet grinding, dispersing, mixing, and blending.


Located in the Qinhuangdao Economic and Technological Development Zone along the coast of the Bohai Sea, the company was founded in 1995 as the predecessor Oulu Chemical Machinery Plant. It now operates a 10,000m² production base and a one-stop material laboratory, offering free pre-purchase testing services ranging from "experimental formula validation" to "pilot-scale proportional amplification." Core products include the WS high-efficiency high-flow (disc) sand mill, the BS pin-type high-efficiency nano sand mill, the PY-DLH dual-planetary dynamic mixer, as well as dispersers and agitators, which are widely used in traditional fine chemical industries such as coatings, inks, pesticides, pigments, dyes, and adhesives.
