Longyan Sanly Hydraulic Engineering Co., Ltd

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, the company occupies land of over 40 mu, 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 world advanced production machines , 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 automatic welding machine for numerical control ring seam , robot welding machine with square choke and round choke , NC washing and drying machine for cylinder barrel and piston rod , ultrasonic washing and drying machine for parts. Company owns precise inspection tool Mitutoyo CNC Tri-ordinate Measuring Machine, Mitutoyo Profilometer, Mitutoyo Rockwell Brinell Hardness Tester, Mitutoyo Surface RoughnessTester and other testing instruments & equipments so as to comply with quality control in the whole production. We have the biggest and the most advanced intermediate frequency heat treatmente quipment in Fujian Province to make hardened layer of 3-5mm , work piece with diameter of 200mm and the length of 2,500mm 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. Centering on surface roughness, company technical center organizes technological breakthrough, succeeds in the research and development of the grinding and polishing machine which is approved as state invention patent and improves the roughness of hydraulic cylinder to Ra0.02.
