2 Because of this new system, the full machine length has been greatly shortened. The Double Center Press Platen has greatly changed the concept of clamping force. Center Press Platens of extremely low flexing are provided on both the stationary and mobile sides. By evenly distributing surface pressure applied to the mold, the platens simultaneously eliminate center-lying burrs and short shots along the periphery, and enable MOLDING at lower clamping forces than complicated and large-sized modes are accommodated owing to a wide tie-bar spacing and ample opening : Outer panelResin: PCNum.

4 MOLDING is stable and consistent because the prescribed clamping force is maintained without being effected by mold rigidity or thermal expansion. Because the set clamping force is applied to the mold, it is unnecessary to set a margin on clamping force, which helps to reduce the required clamping force. The platen greatly flexeswhen applying forceto the top and bottom clamping force is evenly distributed,flash is prevented and gas is readily releasedeven at low clamping pressure measurement of 8-cavity mold for Center Press Platen demonstrates excellent performancethat similarly structured platens of other manufacturercannot compare with.

9 The highly accurate, high output nozzle touch mechanism does not tilt the stationary platen. And, control capabilities are provided to remotely set nozzle touch force according to the type of thickness can be quickly and accurately set by one-touch operation from the controller display. This effectively improves setup performance by shorting mold changeover response to user demands, the CL7000 make a diversity of high-end features safer and easier to use. The machine is fully compliant with JIMS K-1001 (Safety Standard of Japan Society of Industrial Machinery Manufacturers).

10 The energy reducing effect is obvious when compared against hydraulic machines of the same class. Furthermore,technological progress has greatly reduced power consumption compared to earlier ALL-ELECTRIC machines. Users can take full advantage of the sophisticated features at low running costs. Because of the performance limitations of motors, existing electric machines could not retain high pressures for long periods of time. The SE7L comes standard with a high torque INJECTION motor and can retain 3x the pressure loads of existing electric machines.
