ICOMold uses a process called plastic injection molding to produce thousands of plastic parts every day in a range of shapes and sizes.

But what are injection molded plastic parts?

Simply put, they’re parts made using plastic injection molding. In this process, hot liquid plastic is forced into a mold of the desired shape, resulting in a plastic piece that, when dried, permanently takes that shape. It’s similar to how cake batter baked in a cupcake pan will retain a cupcake shape.

For a step-by-step overview of the process, read our recent blog post.

Most of the plastic parts you see every day are made by molding plastic with the help of machines. At ICOMold, we’ve created plastic injection molding parts for everything from specially designed water bottles to hunting tools and accessories.

You may not even think about it because it’s so commonplace, but custom injection molded plastics are all around you and essential to the products found in your homes, businesses, and automobiles. This low-cost process produces high quality parts in large quantities.

But what do you really know about injection molded plastics and the process? Here are five facts to help you better understand this process and what it produces.

1. They are customizable: Change the color or type of material you want us to use. Want enhanced strength? We can add fillers to strengthen the finished part or even other characteristics like flexibility, or resistance to ultraviolet light.

2. They are produced fast: There is normally only 15 to 30 seconds between cycles so a large quantity is produced very quickly.

3. They are less expensive: The speed and efficiency of custom injection molding means costs are lower, so you save money on your budget.

4. They are environmentally friendly: Custom injection molding uses only the required amount of plastic and any test or rejected parts may be recycled.

5. They are ready immediately: When your piece comes out of the mold, it is smooth and there is usually no finishing required, unless of course you require secondary processes.

One of the biggest decisions you can make when it comes to plastic injection molding is deciding which material to use for your part.

This single choice will determine the durability, functionality and color of the piece you’ll be creating. To make the right decision, you must not only look at the material, but also consider the elements your custom injection molding piece will be exposed to.

Will it be outdoors or indoors? Will it be hot or cold? Will there be air or liquid running through the piece? You should also ask about the shrink rate of each material. These are just some of the items to consider when choosing the right materials.

At ICOMold, we have a list of more than 200 materials for you to choose from. This list includes a description of the type of elements these materials can withstand to help you make the right choice for your injection mold part.

ICOMold is a plastic molding manufacturer that uses a complex plastic injection molding process to produce thousands of plastic parts each day in various shapes and sizes.

The process requires an injection molding machine and has four steps. These steps can take anywhere from two seconds and two minutes to complete, depending on how large the molds are and the efficiency of the machine.

Here we outline the process so you have a better idea of how ICOMold is able to produce your plastic parts.

Step 1: Clamping

A special mold is designed to produce the customer’s plastic part. The mold has two halves that are pressed together using a hydraulic clamp. The clamp holds the mold in place during the injection and cooling processes and will open the mold once the plastic piece has been fully created.

Step 2: Injection

This is when raw plastic pellets are fed from a funnel-shaped hopper into the injection molding machine. Once in the machine, an auger screw pushes the pellets through a barrel where the plastic is heated and injected from the nozzle into the mold quickly and with high pressure. This is done for two reasons: 1. the added pressure packs as much plastic into the mold as possible, and 2. the cooling process takes place immediately.

Step 3: Cooling

As soon as the molten plastic hits the mold, the cooling process begins. This is when the plastic hardens into the shape of the mold. The mold cannot be opened at any point during the cooling process and the amount of time needed for a part to fully cool can vary from piece to piece.

Step 4: Ejection

Once cooled, the mold is opened and the plastic part is ejected out of the mold. Sometimes a lubricant is sprayed into the mold before the process begins to prevent pieces from sticking to the mold.

After the plastic piece is fully ejected from the mold, the hydraulic clamp pushes the mold together and the process starts over for the next piece to be formed.

For almost 15 years, ICOMold has produced quality plastic injection molded parts for customers around the world using custom injection molding. We’ve fielded a variety of questions during that time, but here’s one you might not expect:

“What is the difference between injection molding plastic products and injection moulding plastic products?”

The answer is simple: There is no physical difference.

The reason for the spelling difference is that American English uses molding, and British English uses moulding. As a worldwide company, it is easy for ICOMold customers to be accustomed to one spelling and think the other spelling means something entirely different. For example, the spelling with a “u” is used in American English to refer to the crown or baseboard moulding used on the interior walls of homes. So plastic moulding must be crown moulding made out of plastic, right?

In the end, both phrases, “plastic injection molding” and “plastic injection moulding” have the same meaning: we take melted plastic and inject it into a mold, where it cools and hardens to produce a desired shape. Hopefully this will help clear up any confusion you have about the difference in spelling between molding and moulding.

Export MoldExport mold. That’s what we call an injection mold tool that we build in China and ship somewhere else. When we build a plastic injection molding tool for a customer, the customer owns the tool because they paid for it, but it usually stays in our manufacturing plant in China so we can run parts for the customer whenever they need them.

However, sometimes the customer wants us to send the mold over here to the United States so they can run the parts in their own facility or at some other injection molding facility. So, we call it an “export mold” because we’re exporting it out of China to somewhere else.

But is “export mold” really the best term we can come up with for this type of situation? If you think about it, it may not be the most descriptive name. Since the customer is taking physical possession of the tool, maybe we should call it a “customer mold.” But then again, since the customer always owns the tool no matter where it resides, you could say that all our tools are “customer molds.”

Or how about “custom mold?” We are making a custom mold for the customer, that no one else can use, and shipping it to them for their own use. Nope, that doesn’t work either. We don’t make and sell our own parts; we only make custom parts for our customers, so ALL our molds are custom molds.

“Displaced mold?” “Relocated mold?” Hmm. Guess we’re stuck with “export mold” for now, unless someone can come up with a more descriptive term. Do you have one? Maybe we should have a contest to see who can come up with a different name for them!

Smart Manufacturing is talked about quite a bit. It goes by other names, too, like the Internet of Things (IoT), Industrial IoT (IIoT), and Industry 4.0. The term IoT was first coined by Peter T. Lewis in 1985 to describe “the integration of people, processes, and technology with connectable devices and sensors to enable remote monitoring, status, manipulation, and evaluation of trends of such devices.”

So the term has been around for a while now, but the concept still continues to develop and evolve as technology continues to advance through new hardware like sensors, and through the collection and analysis of data. So, how have the advancements in smart manufacturing affected the plastic injection molding business? This article takes a look at the topic.

Benefits of Smart Manufacturing

Smart factories use smart manufacturing to gain production efficiencies, improve production quality and reduce time to market. Machines can now communicate failure points and collect data that can be used to improve predictive and preventative maintenance, which in the long run improves uptime. Data analysis is used to predict and prevent failure; it indicates when intervention is required and recommends the necessary corrective actions. Troubleshooting is more efficient, which benefits both manufacturers and customers.

Sensors, Connectivity and Data

The entire concept of smart manufacturing in injection molding revolves around collecting and analyzing the data. Sensors collect the data and networks transport the data. If a device or piece of equipment on the floor is standalone, it will not contribute to the collective knowledge of the smart factory. Devices and machinery equipped with sensors have the ability to monitor, collect, exchange and analyze data – all without human interaction. The sensors collect data, and communicate better information on the plant floor, as well as outside the plant (or from the outside in) faster, in order to make easier decisions.

Every device that has the ability to gather intelligence needs to be on a backbone of some type that allows it to produce data or have data pulled out of it. New sensor networks can be established, or sensors and data networking can be added to existing devices. The goal in injection molding is to connect the equipment on the plant floor to a network that can monitor, measure, store, and retrieve data.

As for the data itself, decisions need to be made that make the most sense for the injection molder. How and where to house the data is one such decision – should it be kept in-house, or outside of the company walls? Data security is of paramount concern, so if data is stored off premises, remote connectivity and how to safely get into your system from the outside needs to be addressed.

Plastics, in Particular

Since plastics is the third largest sector in the manufacturing industry, it warrants special consideration in the IIoT as it impacts manufacturers and their customers. In terms of injection molding complex components, the data gathered and analyzed can help ensure maximum repeatability in the injection molding process, consistent quality, and low defects. And again, the data also helps determine preventative machine maintenance which helps avoid unplanned downtime.

From the customer perspective, smart manufacturing provides many benefits for communication and visibility. Machine data collection and reporting gives the customer important timing information on project and production order status.

And so it goes. The drive to glean more – and better – data from industrial equipment and systems will continue to improve productivity in the plastic injection molding sector as technology, sensors, and systems continue to evolve, to the benefit of the molders and their customers.
