What are the types of injection molding machines?

Electric injection molding machines
Electric injection molding machines offer many advantages over traditional hydraulic-powered machines. They don't use oil to cool the machine, and are less likely to break down due to a lack of oil. Unlike hydraulic-powered machines, electric machines also require less maintenance and upkeep. The machines are much quieter while running, which is beneficial for clean-room manufacturing facilities. Electric injection molding machines also have low noise emissions. They're more affordable than hydraulic-powered machines, too, and can be purchased for a fraction of the cost.

Hydraulic injection molding machines
As the most widely used plastics processing machines, hydraulic injection molding machines have their advantages and disadvantages, and the decision to purchase a hydraulic IMM will depend on the exact nature of your application. In general, however, the benefits of hydraulic machines outweigh the drawbacks. This article outlines the advantages and disadvantages of both types of machines. In addition, you will learn how to choose the right machine for your needs.

Hybrid injection molding machines
Hybrid injection molding machines differ from standard injection molding machines in a number of ways, including their energy savings. Most hybrid machines feature a hydraulic accumulator and high injection rates of 300 cubic inches per second, whereas all-electric machines are limited to injection rates of 100 cubic inches per second. High injection rates are required when producing thin-walled parts with high L/T ratios. The following are some of the main advantages of hybrid injection molding machines.
