Injection molding (moulding) is a popular manufacturing process used to make many of the items we use every day. If an object is made of plastic, there is a good chance it was made using injection molding. Commercial, consumer goods, industrial, and more all use injection molding to produce products. Injection molding offers businesses the opportunity to create a custom design with details that are unique to their brand.
Industries that Benefit from Injection Molding
Many industries use goods that are made using injection molding.
Medical Industry: Silicone, ABS, polypropylene (PP), and polyethylene (PE) are all common materials used to make medical devices such as syringes and orthopedics.
Toys: The most common example of toys that are injection molded are Legos. Lego bricks are made of ABS which is lightweight, moldable and has high impact resistance.
Automotive: Inside the car, many elements have been injection molded. This includes knobs and buttons on the dashboard, air vents, and more. Common molding materials chosen by automotive companies include polypropylene, PVC, and ABS.
Consumer Electronics: Everyday electronics we use such as the housing of a USB thumb drive to charger cable have all been injection molded.
A few of the injection molded products we interact with every day include the following:
- Game controllers
- Toilet seats
- Cell phone cases
- Cutting boards and other kitchen products
- Flower pots
- Wire ties
- Remote controls
- Shower curtain rings
- Drink dispensers
- Syringes and other drug delivery equipment
- Medical devices
- Laboratory and facility equipment
- Bread and serving trays
- Food storage
- NSF Foodservice products
- Plastic straws
- Protective padding
- Promotional products
- Car bumpers
- Radio buttons
- Window controls
- Drink holders
- Sound and thermal insulation
- Concrete beam conduits
- Electrical plugs
- Electrical switches
- Roof vents
- Deck fasteners
The Injection Molding Process Steps
To begin the process, a custom mold is produced according to the project specifications. The material chosen is heated to its melting point and then delivered to the mold cavity. The molten material begins to cool and take shape inside the mold. Once it has fully cooled, the part is ejected from the mold and caught by a bin. The machine resets to begin the process again. Thousands of parts can be produced using this method.
Why Use Injection Molding for Your Project?
There are numerous reasons that a brand will choose to make a part using injection molding. For example, an electric toothbrush handle houses the mechanism used to power the toothbrush, acts as a base for the brush head, and as a handle for the user. Using a custom injection mold, a company can include these multiple features are built into one design. This reduces the total number of parts or piece count. An injection molding machine can produce a part every 15 to 60 seconds, depending on the material used, design of the part, and size. Electric toothbrushes are mass-produced and require a high volume of production, which leads to lower unit costs over time. Injection molding also facilitates consistency of appearance and a finished product that needs little to no extra finishing, thus the electric toothbrushes will all look identical as required by the project specifications.
Injection molding is a versatile manufacturing method that can be used to make everyday items used by businesses, direct consumers, the medical industry, and more. It has become very popular over the years because it allows for quick mass production and detailed design. It is a cost-effective way to create prototypes and end-use goods.
