Vertical vs Horizontal Injection Moulding: Which One Should You Choose?

We can either make things using vertical injection moulding or horizontal injection moulding. What’s the difference between them, and how do you pick one? Let's learn more.

plastic injection moulding is two methods to make plastic thingsthat are vertical injection mouldingand horizontal injection moulding. Vertical injection moulding: Vertical injection moulding is where the machine pushes plastic into a standing mould. This is where the plastic flows directly into the mould which is ideal for the manufacture of solid parts such as tubes and handles.

Horizontal injection moulding uses a machine to push plastic into a horizontal mould. This allows the plastic to flow more freely into the mould, which is beneficial for producing hollow-shelled objects, such as bottles or caps.

Pros and Cons of Vertical Injection Moulding

There are some positive aspects to vertical injection moulding. For instance, it is good for creating complex forms or for using different hues of plastic. However, the downside is the shape of the final product can be difficult to remove from the mould.

Advantages of Horizontal Injection Moulding

There are premises to horizontal injection molders, as well. It's good for creating things that have to be quite precise, such as medical instruments or electronic components. Additionally, horizontal injection is often faster than vertical injection since they can flow the plastic easier into the mould.

A guide to Finding the Appropriate Moulding Technique

What determines which type of injection moulding you will use? You have to consider what you’re making and what you want it to do. If you are designing something that has complex shapes or multiple colours, vertical injection moulding may be the appropriate option. However, if you want something very specific, or if you want to make plenty of parts quickly, horizontal injection moulding machine may be more suitable.

Factors to Consider when Selecting

When considering the decision of whether to go with vertical or horizontal injection moulding, there are some crucial factors to consider. First, consider the shape of whatever you are making. If it is tall and skinny then vertical injection moulding might be a better choice. If it is flat and wide, it might facade horizontal fully automatic injection moulding machine.

You are also likely considering how many things you want to make. If you need to pump lots out quickly, horizontal injection moulding could be the way to go. However, if you're producing lower volumes of more complex parts, vertical injection moulding might be the answer.
