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 hydraulic 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.
Advantages of hydraulic plastic injection moulding
- It has greater clamp force for large parts
- It has better injection rates
- It has high durability
- It includes larger shot size
- It has better ejection capability
- They’re available with gas accumulators to make up for slower clamp movements
- They have a lower initial purchase price
Disadvantages of hydraulic plastic injection moulding
- They consume large amounts of energy even when idle because they’re so powerful.
- They are nosier than electric machines.
- They are less precise than electric machines.
