A moulding machine also called an injection moulder produces parts in large volumes by injecting the molten materials into a mould. It is used for the mass production of bulk amount of identical plastic products. It is mainly used to produce commonly used products that include plastic items such as bottle caps, syringes, remote-control cases, clips, combs, etc. When it comes to electric moulding machines, there are many ways in which they are much better than hydraulic ones. Besides being more precise and faster, since they do not continuously need hydraulic power, the electricity is consumed only when they run. Moreover, it consumes 50-70% less energy than hydraulic machines.
1. Lower heat emission
Since the electric injection moulders emit less heat, they are made to perfectly suit sensitive environments such as temperature-controlled production facilities and clean rooms. Therefore, lesser heat emission means less harm to the environment.
2. Lower maintenance
The electric injection moulders are free from leakage and don’t need to replace consumables like oils and filters. Moreover, it leaves minimum wastage. Hence lower maintenance is required for electric machines in comparison to hydraulic ones.
3. Unrivaled repeatability
The hydraulic machines are dependent upon pumps, hoses, and valves. On the other hand, electric injection moulders are controlled digitally with servo motors that help perfectly maintain the clamping, injecting, ejecting, and extruding to a great extent of accuracy. Hence, the repeatability that electric machines offer is second to none.
4. No cooling required
The hydraulic machines require cooling as they run hot continuously. But electric injection moulders are calm by nature. Moreover, they don’t need any oil to be changed, and no oil recycling cost is required. Hence there is minimal risk of fire or the environment.
5. Lower cost of operating
Since the electric injection moulders run faster cycle times, the functions and clamps are independent. Hence, shorter cycle times control material usage and reduce the colorant and additive usage in moulding. Unlike a hydraulic machine, regardless of size, the electric machine uses 50-80% less energy.
6. Energy Saving
The electric injection moulders save 25%-60% energy as compared to the hydraulic machine as its energy utilization rate reaches over 95%
The hydraulic machines need hydraulic oils to work. While the oil is used, it spills on the floor, making it dirty and a safety hazard. Since no oils are required in electric injection moulders, there’s no chance of leakage and no mess.
8. High Speed
The electric injection moulders have several electric servo motors, which maintain the high speed of the machines, leading to more production than hydraulic machines.
9. Technology Advancements
The electric injection moulders work digitally with many automated features, including safety features. Hence making it more reliable and better than hydraulic machines.
The above mentioned advantages and a few points you should consider while choosing Electric injection moulders over Hydraulic Moulding Machines.
