Wide-use press machine jigs for joining two metal sheets on a press machine.

ENALOCK series

Caulking metals without fasteners such as welding/joining materials/adhesives.
By incorporating ENALOCK in the die, it is possible to carry out
joining and caulking at the same time, using only the press process.


ENALOCK enables the further reduction of running costs.

  • Suitable joining of the same or different kind metal such as steel, stainless steel,aluminium, etc. is possible.
  • It is possible to use ENALOCK for coated metal sheets because there is no heating process involved.
  • Productivity is enhanced due to the high speed process using press forming.
  • Not necessary to adjust the fitting of the die after replacing.
  • It is possible to replace tools without disassembling the die.
CUTLOCK The die blade can be used for 4 times.

Aiming at minimizing production cost, this is further reduced by the design for long-term durability.


It is possible to join strongly with little pressure. The caulking is strong from the pull from certain directions. It has the necessary strength from a combination of the vertical and horizontal.
