Sewon PM Tech Co,. Ltd. have been specializing in such Powder Metallurgy products as automotive, mechanical and electronic parts etc.
It is needless to say that cost and quality have been always the most important topics in manufacturing industries
have the vertical supply chain structure, starting from casting, punching/stamping, pre-machining, fine machining, spinning, welding of viscous damper in means of laser welding, electron beam welding & argon arc welding, silicon fluids auto-controlled filling station, auto servo-controlled rubber ring pressing machine, auto-dynamic balancing machine, laser/pneumatic markink machine, to painting line.
Test & Verification facility
-frequency tester, static torque tester, ozone tester, hot temperature aging tester, low temperature rubber brittleness tester for rubber damper
-damping performance tester, viscosity meter for silicon fluids for viscous damper
-measurement facilities for torsional vibration amplitude, axial acceleration & temperature, spectrograph for metal element analysis
R&D facility
-have full independent facility & self-made program for measuring & analyzing the torsional vibration amplitude, axial acceleration & temperature
-can provide damping calculation base on engine's equivalent system value (mass elastic data of engine) and excitation data (cylinder pressures at different speed & angle) and the torsional vibration damper can be designed at concept stage of engine development
-the current serial damper can be developed, verified and optimised
