Our press machine manufacturing history began starting from 450 ton hydraulic press in 1924, and it is 100 years in 2023 since the start. Large size press ---chasis forming --- wide variety high volume production
* As of March, 2020
We are among the top servo press suppliers in the world.
Our large size press machines have been delivered to 35 countries in the world, and Komatsu Industries are contributing to energy saving, safety, environment and growth of the automotive industries with our abundant product lineups and innovations utilizing the ICT.
Automotive body panels are formed on Komatsu ServoPress H*FTL line.
*against robot tandem press line
1) Gain higher productivity by high speed feeder and obtaining ample transfer time due to phase difference operation of press machines ( PAT.P )
In addition to double arm feeder, single arm feeder with more flexible panel transfer has been developed and introduced in the market
2) Die interference check and most suitable motion generation by PLS ( press line simulator )
*against mechanical press with air die cushion
Servo die cushion with high-speed response of servo motors achieves high formability and shorter trial times by numerical control
Formed parts Body side outer(deep drawing parts) Measurement items : For panels formed by mechanical press & servo press, sill parts measured and spring backs compared with CAD data. Measurement results Servo press could form almost exactly according to shape of die Mechanical press spring back quantity is approx. 1.7 times of servo press one
* Against mecanical press with air die cushion
Reduced power consumption with power regeneration for servo press and servo die cushion
(Energy-saving effect depends on formed products)
