  • The press adopts the vertical crankshaft structure. The distance of fulcrum is short and the crank is rigid.​
  • The press adopts the low inertia combined dry friction clutch and brake , which has little passive inertia, low energy consumption, reliable interlock of clutch and brake and long longevity.
  • The slide is a whole cast form construction which adopts hydraulic overload protector with agile and reliable action. After overload, it can reset automatically to reduce the down time and improve the availability of press. High pressure oil seal which is imported from German is installed in slide high pressure cylinder.
  • The shut height adopts electric adjustment, which has digital display. Its display is 0.10mm.
