Injection molding parameters

• clamping force,

• clearance between columns,

• diameter of the piston,

• maximum injection efficiency,

• power consumption,

        Drives in injection molding

Hydraulic

Advantages:

• The possibility of continuous 

operation under varying and 
extreme loads

Disadvantages:
• Periodic exchange of filters 

and oils

Electrical

Advantages:

• High speed,
• Accuracy, 
• Easy adjustment

Disadvantages:
• High cost
• There are no job opportunities 

at varying loads
