Japanese Metal Stamper Stays Competitive By Embracing Servo
Press Technologies
Suwa, Nagano, Japan 6/Jan/2006 - In the face of increasing
global competition in the metal stamping industry, Nagano Sankoh
Co., Ltd., has invested US$1.5 million in 4 latest Servo
Stamping Presses to offer greater stamping efficiency of
precision stamped components for the electronics and automotive
industries.
"As competition in the stamping industry gets more intense with
the growth of China metal stampers, Japanese metal stampers have
to embrace new technologies and use them to improve the quality
of the parts being stamped, the productivity of their
manufacturing equipment, the life of the dies and the
flexibility of the manufacturing cells," said Soichi Tamura,
President of Nagano Sankoh.
With the servo press, Nagano Sankoh can virtually key in the
stroke, velocity and dwell profile for any job - all on a single
press. Three of the servo presses are AIDA NC1-1100 (D) servo
presses which offer AIDA's proprietary high torque, low RPM
servo motor with direct drive. These servo presses provide the
same maximum stroke length and torque rating as a conventional
mechanical press while allowing full torque from low speed for
greater part accuracy and longer die life. The servo press does
not increase operating costs because its capacitors store energy
in the non-working portion of the stroke, making power
consumption comparable to or less than that of a standard
mechanical press.
Says Tamura, "These servo presses are nearly double the price of
same tonnage mechanical presses, but we can achieve double the
efficiency in our stamping processes, and provide better quality
parts not possible with conventional presses."
