How to choose the machine clamping force ?

How to calculate clamping force for injection molding machine

Clamping force formula：F = P × S

P= The pressure inside the mold
S= Product Projected Are

What is servo injection molding machine

Servo energy-saving injection molding machine is an injection molding equipment driven by servo motors.
Its main feature is to replace traditional hydraulic systems with servo motors, achieving precise control of pressure and flow in various process sections of the injection molding machine (such as mold closing, injection molding, pressure holding, mold opening, etc.), thereby achieving energy conservation and improving production efficiency.
The working principle of a servo energy-saving injection molding machine is that the pressure and flow rate of the injection molding machine are processed by a computer and driver program to achieve dual closed-loop control of the pressure and flow rate of the hydraulic system.
Servo energy-saving injection molding machines have the following significant advantages:

Efficient and energy-saving；
Precise control；
Quick response；
Good stability；
Environment protection；
