Development of vibration isolation materials, facility vibration isolation equipment, silencers, water hammer cushions, execution of national research projects, complementation and improvement of products.
As an isolator using elasticity and the damping effect of wire rope, this plays the role of a snubber that prevents vibration and a shock absorber that eases shock. Our company develops products that meet various needs by making mounts in various ways using such characteristics of wire rope. A useful mount that prevents vibration caused by exciting forces from being transmitted outside through a supporting part and reduces the dynamic displacement on equipment. Its softening characteristic, in which stiffness is reduced according to the increase of displacement, and the damping effect that occurs due to friction damping between wires are both excellent characteristics.

Damper is the general term that refers to things that eliminate vibration energy by converting it into liquid viscosity or material friction. Our company has developed an integrated total damper by combining a friction damper with excellent damping effect and a wire damper, complementing weaknesses and maximizing strengths. As a result of the dynamic characteristics, the damping effect and elasticity were doubled and anti-corrosion and durability were also improved as all materials were made of stainless steel. Also, it was designed for assembly to respond to various strokes and reaction forces.
An air spring with excellent vibration insulation efficiency, usually used for controlling low vibration of 1㎛ or less and low frequency vibration less than 1㎛. The air spring is usually used in ultra precision equipment such as semiconductor equipment as its natural frequency is low and there is no surging. Our company is developing various kinds of air spring mounts using air elasticity in order to make the air spring used in various equipment. By damping equipment in various ways, it is promoting dynamic safety and quick stability of equipment without the installation of dampers. VAM Type is a closed air spring, which can be used easily without air line connection. It is suitable for damping precision equipment as it has a low natural frequency of 2.0 Hz or less. With its long stroke, VAB Type has been developed to be suitable for the vibration isolation of equipment with occasional heavy vibration. In particular, VZD type can have a more excellent effect than an active system as it can acquire a natural frequency of 1 Hz or less by applying the principle of negative stiffness.

This is an integrated mount that has an excellent effect on impact force and regular vibrations by combining only advantages of an oil-filled damper with those of springs and rubber. In the primary damping, impact vibration is dissipated into friction heat energy through oil and the primary regular damping of exciting force is reduced by rubber part and spring. The upper rubber part is manufactured with CR (neoperene) synthetic rubber, which has great oil and ozone resistance. As apical displacement of the spring occurs after product assembly, a low frequency of less than 5Hz can be maintained.
