Advantages of electric plastic injection machines

Plastic injection has had a great evolution since the end of the last century until today. 

In this transition, the conditions and infrastructure for plastic injection molding production have been modified in order to improve processes and optimize results.

Among the most significant improvements in the plastic injection molding process in San Antonio is the productivity that electric injection molding machines have brought to the forefront to guarantee the quality demanded by the plastic transformation process.

2023 marks the 40th anniversary of the birth of the first electric plastic injection molding machine, manufactured by the Japanese company Nissei. Since then, electric machines have positioned themselves as the number one choice for guaranteed optimization, control, and flexibility.

That’s why today we are going to talk about the main advantages of electric plastic injectors; if you are looking to buy one or produce your plastic objects through its processes, it is of vital importance to know what we will talk about on this occasion.

Which are the advantages of plastic injection electric machines? 

The quality control of plastic injection in San Antonio has many of its key points in the advantages of electric machines, which are enjoyed every day by the different industries where they are implemented.

So join us as we review the most important benefits of electric plastic injection molding machines.

1.- Risk reduction

Several factors make risk reduction a reality with electric plastic injection molding machines.

For example, by not generating heat to start its operation with oil, the electric injection molding machine exponentially reduces the risks of plastic production. In this sense, the low heat emission of electric plastic injection machines generates a safer and more controlled environment, suitable for industries of all types and nature.

2.- Energy reduction

Electric plastic injection molding machines reduce the energy used by up to 70% compared to hydraulic machines.

This index keeps increasing thanks to the simplification of the electric machine parts, that precisely solve any kind of problems with electricity to reduce energy consumption.

One of the most important keys is that, by not using hydraulic pressure as the main source of energy, electric machines generate a lower and more efficient consumption of energy. Thus, the operating and running cost of an electric injection molding machine will always be much lower than that of hydraulic injection molding machines.

This is even more important today as, in the face of intense climate change, injection molding machines make it possible to achieve even lower energy consumption.

3.- Pollution decrease

Electric plastic injection molding machines work without generating as much noise as hydraulic machines, while controlling noise pollution. Thus, the noise generated by electric injection molding machines is approximately 20 decibels, compared to the 70 decibels generated by hydraulic machines.

This has a direct impact on savings in the cost of acoustic insulation of the plants or companies, allowing also a better relationship between the industrial complex and the inhabitants near it.

4.- Lower costs of maintenance

The simplification of the processes established by the nature of electrical machines has a direct impact on their low maintenance cost.

This is due to the reduction of costs also in the production of the parts of the machine, as well as in their global maintenance, because since its birth, the electric injection molding machine is designed to give the least amount of problems and if there are any, solve them in the same way: quickly and with the least possible investment.

5.- Procesos simplificados

A key part of electric plastic injection molding machines is their various electric motors (better known as servomotors), which have systems for regulating critical machine variables such as position, speed, or acceleration.

These motors supplanted several parts of hydraulic machines, such as valves, hoses, or pumps. In this way, electric injection machines are a clear example of today’s industrial technological development.

6.- Precisión total

Electric plastic injection molding machines work without generating as much noise as hydraulic machines while controlling noise pollution. Thus, the noise generated by electric injection molding machines is approximately 20 decibels, compared to the 70 decibels generated by hydraulic machines.

In this way, various specialized parts, such as medical devices made with plastic injection molding, are becoming increasingly common and in demand to be produced electrically.

7.- Major production

Electric machines for plastic injection are much faster than hydraulic machines, due to what we have already mentioned because they make possible the execution of simultaneous processes, optimizing time, space, and resources.

The simultaneous processes are carried out through the independent transmissions that each axis of the machine has, which is unthinkable for hydraulic injection molding machines. 

Most hydraulic machines need to heat oil to start their processes, which is not the case with electric injection machines, and their start-up times are considerably faster.

Derived from this, electric machines do not require cooling, unlike hydraulic machines. This way, electric injection molding machines produce many more parts than hydraulic machines.

8.- Universal application

Practically any part can be produced by an electric plastic injection molding machine. For a couple of years, electric machine production has become increasingly specialized, increasing the benefits for new and old products and companies of all sizes.

Finally, you must keep in mind that for the design and implementation of a clean room for plastic injection, it will be necessary to have electrical machines that optimize all your processes.
