Established in 2001, Longyan Sanly Hydraulic Engineering Co., Ltd is a modernized high-tech enterprise integrating the design, production and sales of hydraulic cylinder and various hydraulic components. Currently, our company occupies land of over 27000 square meter, with total investment of RMB over 300 million. Company now owns more than 180 employees, lower turnover skilled workers is also a treasure of our company.

Company owns word advanced production machiness, Japan AIOH TEC SRB Skiving Roller Burnishing with Double Rotary, Japan Moni Seiki CNC Lathes, Japan Mazak machine center, Korea N. C Buffing Machine, Korea Doosan CNC Lathes and automatie welding machine for numerical control ring seam, robot welding machine with square choke and round choke, NC washing and drying machinee for cylinder barrel and piston rod, ultrasonic washing and drying machine for parts.

We have precise inspection tool. Mitutoyo CNC Tri-ordinate Measuring Machine, Mitutoyo Profilometer, Mitutoyo Rockwell Brinell Hardness Tester, Mitutoyo Surface Roughness Tester and other testing instruments & equipments so as to comply with quality control in the whole production. Centering on surface roughness, company technical center organizes technological breakthrough, succeeds in the research and development of the grinding and polishing machine and improves the roughness of hydraulic cylinder to Ra0.02.

We have the biggest and the most advanced intermediate frequency heat treatment equipment in Fujian Province to make hardened lalyer of 3~5mm, work piece with diameter of 200mm and the length of 2500mm and solve heat treatment problems of the parts such as crankshaft, large gear, grinder spindle and large-scaled hydraulic cylinder which bear high distortion and high pressure. In addition, surface stress is less than that of high frequency heat treatment equipment so that such product is powerful in market competence
