Have you ever wondered where the various objects in your house come from? We’re not talking about the shop or even the country of origin, but rather how these objects were made before eventually arriving in your home.
With so many manufacturing methods around, you might not know that most of these products come from the design and manufacturing process for injection molded plastics. You likely have hundreds of different objects in your home created with this technique, but to emphasize how common these items are, we’ve put together a list of everyday injection molded parts.
Why Injection Molding Is Popular with Household Product Manufacturers
It is incredibly easy to find items around the home that are, in fact, injection-molded products. Many manufacturers prefer the injection molding production method for a few key reasons. Across large commercial manufacturing runs, injection molding offers several significant advantages, such as:
- A high degree of precision that can create molds for many differently shaped objects without compromising on design tolerances.
- Rapid production capabilities, with molds capable of producing a high volume of parts or products daily at cost-effective prices.
- Long-term reliability, thanks to durable molds that can withstand tens of thousands of manufacturing cycles before requiring maintenance or replacement.
With such a versatile process available to manufacturers, it’s no surprise these products are found everywhere. Injection molding products have only gotten more popular in recent years.
10 Common Injection Molded Household Products
So what are some of the most common injection molded objects often found in households? The average homeowner can easily find just about every single one of the following objects in their homes. Let’s consider what’s made by plastic injection molding and why.
1. Plastic Bottles
Given the uncountable number of different beverage products on the market, you are more likely to have at least one injection-molded plastic bottle in your home. PET, a common plastic material for bottle design, flows easily through injection molds and creates durable yet lightweight products for use as liquid containers. Even reusable plastic products, such as refillable water bottles, come from injection molds.
2. Bottle Caps
All those lids for those plastic bottles? Yes, they also come from injection molds. Since these items tend to be small, it is easy to design mold tooling to produce enormous quantities at once. With the high demand for plastic lids and caps across many industry verticals, it should be no surprise that the rapid throughput of molding machines is the manufacturing method of choice.
3. Legos and Toys
Toys for children are also among the most common injection molded plastic parts for several reasons. First, you can expect complex toy designs and true-to-life colors from injection molds. Second, the ability to combine materials allows the molding systems to produce huge volumes in a relatively brief time. Lastly, the material selection also contributes to the popularity of this method with toys, because it is easy to make non-toxic, non-porous, and easy-to-wash products.
4. Computers and Other Consumer Electronics
While injection molding doesn’t contribute much to the major hardware components on computer circuit boards, it touches almost every other aspect of these devices. Everyday items that undergo injection molding for use in computers include laptop shells, speaker housings, computer monitor bezels and even the keyboards you type on every day. The durability of these materials makes them well-suited to the long lifespan requirement for most computer hardware. Additionally, things such as light switches, other electronic housings, and a wide range of appliances also come from injection molds.
5. Kitchenware
Molding works well for various kitchen products, such as plastic plates and utensils. These products must often be resistant to elevated temperatures, easy to clean, dishwasher safe, and non-toxic. Injection molds can mold materials that meet all these requirements at high volumes.
6. Plastic Furniture
While the classic wooden chair still has its place in the home, a wide variety of modern furniture, especially chairs, now feature all-plastic construction. Injection molds can produce these parts to exact tolerances for consistency between production runs. At the same time, making molds large enough to create full-sized furniture or components that will undergo assembly by the user at home is also straightforward.
7. Flower Pots
Terracotta pots are lovely, but they’re expensive. Plastic flowerpots provide the same stable space for plants to grow while resisting breakage and lasting for a far longer time. Thanks to the tooling design, these everyday items and garden products also come out of injection molds, as it is easy to create the necessary shape while leaving drainage holes at the bottom with few to no additional manufacturing costs.
8. Toilet Seats
There are more plastic parts in and on a toilet than you might expect, but the toilet seat is the most prominent example. With various shapes and sizes, such an injection molding product takes advantage of the same plastic properties other products do. These properties include bacterial resistance, a non-porous surface that can undergo sterilization and a high degree of long-term durability. The toilet hardware itself will likely wear out long before the seat ever does.
9. Medical Devices
If you have any medical devices at home, such as heart-rate monitors, blood-pressure monitors, or even syringes, the odds are high that they came from injection molds. For a home, the injection molding machine can mean the difference between affordable medical devices that meet strict requirements versus expensive products that only businesses can afford.
10. Wardrobe-Related Products
From the hangers in your wardrobe to the plastic frames of some mirrors or plastics used to house makeup, injection molds have a footprint everywhere. Since quick turnarounds and big orders are a key requirement for these industries, injection molds are the obvious best way to get it done.
