Injection Moulding Machines: Types & Benefits

If you’re seeing this, you may already be familiar with plastic injection molding. We use this process very often in plastic production for many reasons. The primary reason is that, out of all the methods available, it is the most efficient for producing large quantities of the same plastic parts. 

Injection molding is also used for a wide range of products that serve many applications. What businesses and manufacturers value is that it is a cost-effective solution that also produces very high-quality end products.

There is a large variety of plastic molding machines out there, which will depend on the product you are making and how the machine in question will play a role in the result.

In our blog post, we will be looking at the different categories of plastic injection molding machines and the benefits of each, which in turn will help you choose the right one for your next project with confidence.

Types of Plastic Injection Molding Machines

Injection mold equipment is put into categories by structure and performance. What each type has in machine parts is different, which in turn causes variation in operation, use, and production results. 

To get the best from the injection molding process, it is important to know these machine types and how their parts interact.

Horizontal Injection Molding Machines

Horizontal injection molding machines are what you’ll see the most of in the industry. We see that they have a horizontal clamping unit and injection unit, which in turn makes them very good for mass production and a large range of part designs. 

In this category of injection molding, we find machines that have been designed with a compact, low-profile body, which in turn produces rapid mold cycles and easy operation. 

They are very flexible in what they do, which includes the use of multi-cavity molds, and are also very much at home in large-scale manufacturing, where they perform consistently and achieve high production output.

Some benefits of a horizontal injection molding machine are:

• Generates large-scale and complex shapes with precision.

• Supports a variety of cavities and color molds for many applications.

• Provides better production efficiency and lower operating costs.

• Improves mold alignment and performance during operation.

Vertical Injection Molding Machines

Vertical injection molding machines feature a vertical clamping unit and injection system. In this, they do very well at insert molding, overmolding, and special applications.

Also, due to their design, which provides easy access to the mold area, these machines are great when it comes to putting in components like metal inserts or threaded parts, which require precise placement. This type of plastic molding machine is common in industries that require fine detail and compact systems.

Some in favor of a vertical injection molding machine are:

• Reduces complexity in insert and overmolding for large assemblies.

• Compact design, which is a space saver in production facilities.

• Improves accuracy in small, complex components with close tolerances.

• Enables mold access, which in turn improves operator efficiency and flexibility.

All-Electric Injection Molding Machines

All electric machines we see are using servo motors for all of their movement, which in turn we see replacing hydraulic systems. This gives them superior precision, energy efficiency, and low noise performance during operation. Instead of hydraulic systems, what we see is the use of high-speed servo motors for all of the machines’ movements, which in turn we present as making their operation cleaner, quieter, and more energy efficient.

An option of all-electric PP molding machines is for when you are looking for quick cycles, cleanroom compliance, or reduced environmental impact. They are also very much used in electronics, medical parts, and high-accuracy components.

Once we have the settings for a product fine-tuned, the same quality may be achieved time and time again. This, in turn, leads to reduced waste and lower labor costs, which in large part is because machines may run automatically with little supervision.

Some benefits of the all-electric injection molding machine are:

• High-quality performance and consistency in critical applications.

• Energy smart, which also means lower on the energy scale and better for the environment.

• Low noise levels improve workplace conditions.

• Reduced maintenance with fewer moving parts and no hydraulic fluids.

Hybrid Injection Molding Machines

Hybrid systems, which are a mix of hydraulic and electric systems, are what we see in these machines. We see in them the use of a servo pump, which allows for continuous change, which in turn improves efficiency and response time. 

Also, they are very much the choice for businesses that wish to have the flexibility of producing a large variety of parts without the need to purchase many separate machines.

In the area of plastic molding machines, hybrid machines are ideal for manufacturers that want to balance performance with sustainability without compromising part quality or speed. They deliver the power required for high‑pressure molding while operating in an energy‑efficient and precise way.

Many hybrid models are also designed to handle polypropylene efficiently, making them suitable as PP molding machines for high‑volume production.

Some benefits of a hybrid injection molding machine are:

• A hybrid of hydraulic power and electric accuracy.

• Energy-efficient compared to fully hydraulic machines.

• Supports high-speed production with consistent quality.

• For large-scale and complex parts.

Note: Pp molding machine range includes devices that work with polypropylene (PP) and may be of any type mentioned above as long as they present the right processing conditions for PP resin.

Summing up,

Behind every high-quality plastic product is a machine built to deliver precision, consistency, and innovation. Your choice of a plastic injection molding machine can define your growth in the competitive market. 

It is not only about speed, which it should have; what we look at is quality, reduced waste, and staying ahead in the market. Each project is different, which is why at Boss Automation, we help you design and produce parts that meet the highest standards.
