  • Calculation of clamping force of vertical injection molding machine

    Calculation of the clamping force of the vertical injection molding machine The clamping force of the vertical injection molding machine is expressed by the maximum value of the clamping mold. The pressure of the injection molding material injected into the molding space acts on the direction of opening the mold, so it must be below the clamping force. Generally, the material pressure must be less than 80% of the clamping force. Material pressure is the product of the parallel pressure per unit area of the forming space forming the projected area of the forming space

  • What can injection molding factories do to make money?

    What can injection molding factories do to make money? A Japanese injection molding colleague said: Whether an injection molding plant can make money, in practice, it is the control and management of the consumption process. If the management is in place, the injection molding machine is a banknote printing machine. If the management is not in place, the injection molding machine will become a money burning machine. " "Effectiveness after management" has a very clear effect in the injection molding plant. Ancient injection molding production enterprises of vertical injection molding machines are being retired.
