There is a significant difference in production efficiency between hydraulic injection molding machines and all-electric injection molding machines

Molding Efficiency

All-electric Injection Molding Machines:
Because servo motors directly drive each actuator, all-electric injection molding machines have relatively short molding times. For example, data shows that the molding time of an all-electric injection molding machine is only one-third that of a fully hydraulic injection molding machine.
All-electric injection molding machines have very fast injection speeds, typically exceeding 300 mm/s, far exceeding the typical injection speed of hydraulic injection molding machines (around 100 mm/s). This enables all-electric injection molding machines to meet the demands of high-speed production and improve production efficiency.
Each actuator in an all-electric injection molding machine is driven by an independent servo motor, enabling complex motions such as simultaneous ejection during mold opening and simultaneous mold closing during plasticizing. These features further enhance the production efficiency of all-electric injection molding machines.
Hydraulic Injection Molding Machines:
Hydraulic injection molding machines have relatively long molding times because they require more time to heat and cool the material.
The relatively slow injection speed of hydraulic injection molding machines limits their production efficiency.
The movements of hydraulic injection molding machines are often limited by the hydraulic system, making complex motions difficult to achieve, thus affecting production efficiency. Cost of Use
All-Electric Injection Molding Machines:
Due to their high-precision servo motors and advanced control systems, all-electric injection molding machines maintain high stability and accuracy over extended periods of operation, reducing scrap and downtime.
All-electric injection molding machines also have lower energy consumption, helping to reduce production costs.
Hydraulic Injection Molding Machines:
Hydraulic injection molding machines have higher energy consumption because the hydraulic system consumes a significant amount of energy to power various movements.
Maintenance and servicing costs are also relatively high, as the hydraulic system requires regular oil changes and filter cleaning.
Degree of Automation
All-Electric Injection Molding Machines:
All-electric injection molding machines are typically equipped with advanced control systems and automated features, such as automatic feeding, automatic detection, and automatic adjustment. These features help improve production efficiency and product quality.
Hydraulic Injection Molding Machines:
Hydraulic injection molding machines have a relatively low degree of automation and typically require more manual operation to monitor and adjust the production process. This can reduce production efficiency and increase labor costs.
In summary, all-electric injection molding machines are generally superior to hydraulic injection molding machines in terms of production efficiency. With their shorter molding times, faster injection speeds, and multi-motion capabilities, all-electric injection molding machines are well-suited to high-speed, high-precision production demands. Furthermore, their lower energy consumption and lower operating costs help reduce production costs and improve profitability. However, hydraulic injection molding machines still offer advantages in certain specific applications, such as those requiring greater clamping force or molding large parts. Therefore, the selection of an injection molding machine requires careful consideration based on specific production needs and budget.
