  1. *mark figure varies depending on molding conditions.
  2. Figures in are optional.
  3. The applicable max. injection pressure and holding pressure will be restricted according to the material in the real molding operation.
  4. The figures for the max injection rate and the max. injection speed are calculated ones. The actual injection rate and injection speed will be restricted by pressure. Actual setting pressure may be restricted by molding conditions and cycle time.
  5. The figures are subject to change without any legal obligation on the part of the manufacture.
  6. A large-sized screw may not be applicable to some kinds of material.
