Insert molding combines different materials into a single item. While it is very much like other types of molding processes, it affords advantages that are not otherwise possible.
If you are unfamiliar with insert molding, the information below will give you an idea of the many benefits it offers. Keep reading to find out how it can help your industry produce better products and save money.
Insert Molding Basics
Insert molding is similar to basic injection molding. Like injection processes, it involves putting melted plastic resins into a mold where they cool and solidify.
The only difference in insert molding is that manufacturers can place components in the mold before it closes. This allows the plastic resins to form around it. As it hardens, the result is a customized part that takes less time to make and weighs less than an all-metal alternative, making it a key process to leverage in DFM.
It is possible to insert many different types of materials in the mold. These include magnets, tubing, mounting brackets, screws, and almost any metal component.
This advantage reflects the shift of many industries in replacing metal parts with plastic ones. Plastic offers lower weight and, depending on the part, comparable durability in operation. It also is resistant to corrosion, unlike most metals.
There are many advantages to this availability. Here are seven to consider.
1. Durability
One big advantage of insert molding is that it affords enhanced product design and manufacturing. The precision with which you can place inserts into a mold design cannot be achieved with other molding processes. In short, plastic parts with integrated components are much stronger and more reliable.
Also, since there is no assembly involved in this one-step process, there is less opportunity for error in manufacturing.
2. Weight
Plastic parts can be up to 50 percent lighter than their metal counterparts. This, combined with strength, is one of the primary reasons that industries are turning to plastic molding for parts. From fuel efficiency to better ease-of-use for surgical instruments, lighter weight enhances performance and functionality.
3. Size
The insert molding process allows the production of parts that are much smaller or thinner, without sacrificing durability or performance. A simple example is vehicle components. Thinner door and console parts mean more room in the interior of the car.
4. Economical
Insert molding achieves cost savings in two ways. First, they allow the use of much cheaper materials. In general, resins are much more affordable than metals.
Also, molding production processes themselves are cost-effective. Insert molding is a one-step process. Unlike other types of molding, assembly and labor costs can be streamlined.
5. Efficiency
Insert molding eliminates a second assembly step in the manufacturing process. The insertion of metal or other components is integrated with the molding step, so there is no need for a stand-alone task. This saves time and money associated with labor and specialized equipment for these processes.
6. Variety of Materials
Insert molding can use many different types of plastic resins in the process. These including thermoplastics, which are eco-friendly since you can recycle them. The most common thermoplastics are polyethylene, polystyrene, and nylon. These are all lightweight, durable, and ideal for consumer products to heavy-duty industrial ones.
Other common materials are thermosets, such as epoxy, and elastomers. Natural rubber, which is both strong and flexible, is a good example of the latter.
7. Variety of Designs
Besides materials, insert molding allows many different types of shapes and designs for its parts. This is often not achievable using metals. It&#;s obvious how unlimited configurations have expanded the range of possibilities for engineering and design in different industries.
Leveraging These Advantages
Because of the advantages cited above, we are seeing many industries shifting toward insert molding for plastic components. One example is automotive manufacturing and trucking. This is due to weight reduction, which means better fuel economy. This has been a huge asset in manufacturers continuing to meet federal fuel-efficiency standards.
Besides replacing non-mechanical parts like side panels, many polymers are being used in engine parts. They can reduce weight without compromising performance in the motor.
The medical field is a common industry where we are seeing more plastic parts with integrated metal components. This includes many surgical tools and devices.
That is why you are seeing more consumer product manufacturing moving towards plastics. Likewise, aerospace and aviation engineers are turning to high-quality molded plastic for aircraft parts. Like in the automotive sector, lower weight is a vital asset to aeronautics manufacturing.

Plastics have become an asset in military and defense equipment manufacturing as well. It allows the production of lighter gear for the troops. It also has afforded many advantages in armed forces vehicle production, including stealth and armor upgrades that would not be possible using metals.
Finally, a niche industry where plastics have replaced metal parts is LED lighting. The plastic housing is much more versatile and does not absorb heat as metal ones.

Injection moulding is an affordable, versatile, and efficient manufacturing process that has earned an admirable place within the business of any production company.
It&#;s used to make everything from Gameboys to gears, and with the process standing as one of the best options for businesses developing products. There&#;s a myriad of benefits to swapping over to it today.
Notable products created by injection moulding
If you take a quick look around your house, you can probably find numerous objects that were made using plastic injection moulding &#; even the computer or smartphone you&#;re viewing this on. Countless products are completely reliant on this process for their manufacture; many which are common items we use on a daily basis.
- Car interiors: You may not realise it, but the interior of most cars are made up by injection moulded plastic components. In fact, every time you get into your vehicle you are surrounded by parts made from plastic injection moulding; the dashboard, radio buttons, window controls and plastic cupholders are all made this way. Injection moulding is also used to make some exterior car parts, such as the bumper, door handles, roof racks, lights lens and hub caps.
- Children&#;s toys: Most children&#;s toys &#; from Lego to Barbie dolls &#; are made from injection moulds. The reason for this is that plastic is the ideal material for children&#;s toys: it&#;s versatile, durable, waterproof and also easily cleaned.
- Medical devices: The healthcare industry relies heavily on products made from plastic injection moulding. In fact, many medical devices used both in facilities and at home are crafted from injection moulding. This process has allowed medical devices to be manufactured safely, precisely and efficiently. The medical industry relies on plastic injection moulded products as they are versatile, lightweight, sanitary & very cheap to produce.
Injection moulding is an ideal manufacturing solution as it can be used to produce a wide range of products efficiently and cost effectively. Here, we look at 6 ways injection moulding can benefit your business:
1. It&#;s affordable, easy to source, and widespread
The biggest advantage of injection moulding is a three-pronged feedback loop that keeps on benefitting you and your company the longer you use it.
Speaking of labour costs, another added advantage to the moulding process is how easily automatable it is. It requires very little supervision and oversight once the ball starts rolling. Our own machines are fully programmable with reproducible conditions that can be replicated with a touch of a button.
2. It&#;s very fast
We use injection moulding when it comes to creating products in bulk. The reason for this is the sheer speed of production and the cost efficiency of the process, parts can usually be produced in seconds.
The speed of production also means that the time saved on production speeds up your business processes. It means that you&#;ll be spending less cost on associated labour and profiting from the output.
3. It&#;s extremely efficient
Injection moulding produces very little waste. Not only is it one of the most efficient users of raw material, but any excess isn&#;t wasted; you can simply recycle it back into the machine for future components.
While the mould themselves can be expensive to produce, you&#;ll be able to recoup that quickly once you begin production, often in magnitudes of 10-20 times the savings in large batch scale operations.
Your labour costs will be barely noticeable when you consider that you won&#;t need to waste additional time joining or trimming your final products, as well as less rejects to deal with due to human error.
4. It looks good straight out of the mould
A lot of different casting products require finishing after the moulding process. One fantastic advantage of injection moulding is that they come finished right out of the mould looking great and ready to use.
5. It&#;s strong
As part of the moulding process, you can add fillers or additives to the moulded part via plastic injection process in order to create reinforced and stronger products, an option that most other processes lack.
6. Injection moulding is customisable
As a combination of the availability of customisation options and the ease of customisation in the process itself, there&#;s a lot you can do with injection moulding to mix up your project.
For starters, there&#;s a wide spectrum of materials and colours that you can use in the process, but assuming you fit the basic design criteria you&#;ll also have a lot of flexibility in how you approach your design.
On top of that, you can use different types of plastic throughout your cycle. Plastic can be co-injected so that a machine can process two different plastic types in the same process!
