MIL-STD-648

Impact Test

Dummy load is installed in the container and placed on a platform in its shipping condition and then suspended by wire ropes.

This allows container to swing. Release pendulum and run into a barrier.

１７

Free-Fall, Edgewise and CornerwiseDrop Test

Dummy load is installed in the container and perform free-fall, edgewise and cornerwise drop tests from specified height in its shipping condition.

40 years of experience

• Pioneer and builder of ECM Machine • ECM service supplier to aircraft industry• Up to 20000 ampere and five-axis machine• Metal is removed without the use of mechanical or

thermal energy

Advantage of ECM•Non-contact process•Generally no tool wear•Regardless of metal hardness•Rapid metal removal rate•Less heat and mechanical stress•Finish complex shape in one pass•Free of burrs

２７

EC DEBURRING (ECD)

• Deburring difficult-to-reach areas• Deburring of several tens of

intersections in a single process• Components used in hydraulic,

pneumatic and mechanical systems• Process time between 5 and 20

seconds• No secondary burrs• Tailored to meet production line

requirements
