Plastic injection molding is the backbone of modern manufacturing and is used to make a multitude of everyday items. This process creates plastic parts with complex shapes with precision, consistency, and cost. We encounter and interact with a myriad of injection-molded components all day, every day, even if we don’t know it. Let’s look at some of the most common types of products that use this process.
Home and Kitchen
Our homes are full of injection molded products, especially in the kitchen. These products benefit from the durability, cleanliness and design flexibility of the injection molding process.
- Food storage containers and lids: The airtight seal on your favorite leftover container is made possible by injection molding.
- Utensils and cutlery: Plastic forks, spoons, and knives are made quickly and cheaply by injection molding.
- Small appliance parts: Your coffee maker’s water reservoir, blender base, or toaster lever probably started life in an injection mold.
The ability to make these items in high volume and consistent quality makes injection molding the choice for kitchenware manufacturers. Plus, the process allows for multiple materials or colors to be combined to increase functionality and aesthetics.
Personal Care and Hygiene Products
The bathroom is another space full of injection molded products. The precision required for these personal care items highlights the capabilities of modern injection molding.
Toothbrushes and razor handles are examples of injection-molded products. These items require ergonomic design and often have multiple materials—a perfect application for multi-shot injection molding. The molding process facilitates the creation of comfortable grips and the combination of different textures and colors.
Bottle caps and pump dispensers also use injection molding. The tight tolerances allow for these parts to fit and function perfectly. From shampoo bottles to hand soap dispensers the seamless operation we expect from these products is a result of injection molding.
Cosmetic packaging is another area where injection molding excels. The process allows for intricate design, smooth surfaces and even transparent parts – all important in the competitive cosmetics industry.
Toys and Recreational Items
The toy industry has been transformed by injection molding, making the following possible:
- Complex shapes and intricate details
- Bright colors and varied textures
- Durable and safe products
- High volume production at low cost
Building blocks like LEGO are an injection molded toy classic; millions of blocks fit together perfectly due to precision that is achieved by injection molding. Action figures, doll accessories and board game pieces are other examples of parts that can be economically mass produced in this manner.
In sports and recreation, injection molding makes parts for everything from bicycle helmets to golf tees. The ability to make lightweight yet durable parts makes it perfect for sporting goods manufacturing.
Automotive Parts
The automotive industry uses injection molded parts to reduce weight, cut costs, and increase design flexibility. Some examples are:
- Interior trim pieces
- Dashboard components
- Center console parts
- Exterior parts like light housings and grilles
Injection molding allows automakers to make complex shapes that would be difficult or impossible to make with metal stamping or machining. The process also allows for combining different materials like soft-touch surfaces on hard plastic bases.
Electronics and Technology
Our digital world is made of injection-molded parts. From the casings of our smartphones to the keys on our keyboards, plastic injection molding is everywhere in consumer electronics.
- Smartphone and laptop casings need durability, heat resistance, and aesthetics – all achievable with injection molding.
- Computer peripherals like mice, keyboards, and headphones use ergonomic design that is made possible by the flexibility of injection molding.
- TV and monitor bezels show off the ability of injection molding to make large, precise parts with great surface finish.
The miniaturization of electronics has pushed the limits of injection molding, requiring tighter tolerances and more complex part geometries.
Medical Devices
When it comes to medical devices, injection molding is critical in making safe, sterile and precise parts. Some examples are:
- Disposable syringes and medical tools
- In vitro diagnostic cartridge components
- Prosthetic parts / braces
- Diagnostic equipment housings
The ability to make complex, lightweight parts with biocompatible materials makes injection molding essential in medical device manufacturing. The process also allows for antimicrobial additives to be added to the material for medical products.
