Molding Mechanical/hydraulic hybrid two-sided CFRTP molding machine

Technical Classification:
[ Molding ]
[ Equipment / Facilities ]
[ 2-sided ] [ high-speed ] [ holding ] [ molding ] [ opening/closing ] [ Press ] [ pressure ] [ Thermoplastic ]

Point of the Proposed Technology

Including two pressure plate surfaces, each of which can be set to different temperatures and different pressures (420ºC Max)
The holding pressure and position can be controlled by mechanical servomechanism, while realizing high-speed mold opening and closing and bottom dead center accuracy. And also no restriction on pressurization holding time
Suitable eccentric load and minimum machine height due to underdrive mechanism


Capable to correspond with various construction methods using CFRTP material which will draw attention in the future

Conventional Technology

Machine presses that are good at high-speed mass production are not suitable for resin molding because of the weak pressure holding control.
However, for a hydraulic press suitable for holding pressure,
 ・It is inevitable to increase the scale of the equipment in order to increase the speed.
 ・A special mechanism is required to maintain the parallelism against eccentric load.
 ・Maintenance is difficult due to the need of a large amount of oil.
 As stated above, there are many disadvantages in constructing high-speed mass production systems.

New Technology

We propose a press equipment combining mechanical and hydraulic advantages.
・Realizes high-speed mold opening and closing, high bottom dead center accuracy and reproducibility by mechanical servomechanism,
・Hydraulic servo mechanism enables holding pressure control and position control. And no retention time limit.
