Injection molding machine are classified mainly by the type of system that drives them: Hydraulic, electric, or hybrid.
Hydraulic injection machines uses ram system for its clamping mechanism. This type of machine is used by majority of molding companies.
Electric injection machines are driven by motors. Unlike the hydraulic machines, which continously pump hydraulics to the cylinder throughout the whole molding cycle, an electric machine only makes use of energy during closing and openning of the clamping unit. It uses toggle system for its clamping mechanism in order to build up tonnage.
