When it comes to plastic injection moulding, design engineers have three main options of machine designs to choose from.  These three types of machine designs include fully hydraulic, fully electric and hybrid machines. Each has its benefits and disadvantages and in order to select the process that suits your requirements you need to know what each process is and what it can offer you.

In this two-part post we’ll help you get to know the hybrid plastic injection moulding just a little bit better. In part one of our post we’ll focus on what exactly it is and what it’s used for while part two will look at some of the advantages and disadvantages of this popular injection moulding option.

So what is hybrid plastic injection moulding?

Hybrid plastic injection moulding machines bring together some of the key features of both hydraulic injection moulding machines and electric injection moulding machines. What has attracted many manufacturers to these machines today is that they bring together the precision and energy-efficient operation of an electric motor with the proven pressure-generating capability of hydraulics. They also offer an alternative to toggles for moulders who prefer the “feel” of direct hydraulic clamping.

The secret to the savings behind hybrid machines is that the screw rotation has been electrified. 66% of energy use in traditional hydraulic injection moulding machines is used for screw recovery, so while hybrid presses are costlier upfront, their electrified screw rotation can result in significant savings, which can then be passed on to customers.
