*1) Smaller mould than this size may limit clamp force.
*2) The maximum injection pressure and maximum pack pressure is not melt pressure but injection unit output.
- The maximum injection pressure and maximum pack pressure is the maximum value can be set.
- The maximum injection pressure and maximum pack pressure might be limited depending on the moulding condition.
*3) Maximum injection rate and maximum injection speed is a theoretical value.
- Maximum injection rate and maximum injection speed can not be guaranteed when the injection pressure is
maximum.
*4) The maximum injection pressure setting at high pressure filling mode option.
- There is a limitation in injection time setting and pack time setting, when high pressure filling mode option is selected.
(Contact sales for detail)
- High pressure resistance barrel and nozzle are necessary, when high pressure filling option is selected.

*5) The machine without option.
*6) The pressure conversion is 1MPa=10kgf/cm2.
*7) The moulding condition might be limited by the resin.(Contact sales for detail)
