Injection molding is another type of plastic fabrication that can be used to create parts and products. This versatile fabrication process can be used to mass produce items, whether you need hundreds or millions of pieces at a time.
Choosing the right plastic fabrication method is key to the success of your project. Read on to find out more about the capabilities of plastic injection molding in Utah.
What is injection molding?
Injection molding uses melted resin or liquid polymers to fill a steel or aluminum mold. The plastic components are heated until they’re molten, then they’re injected into a mold with great force. The melted plastic fills the mold, then hardens as it cools. When the molds are cool enough, the plastic parts can be released.
Before a part can be created, however, a designer and engineer have to create the mold. Designers take into account the basic size, shape and features of the part, as well as the benefits and limitations of the materials that will be used. It’s a precise process that needs the help of a skilled parts designer—if the two halves of the mold don’t match up perfectly, the results will be less than useful.
Injection molding generates less scrap product, as opposed to CNC machining and other plastic fabrication methods. Plus, once the mold is perfected, it’s a simple and repetitive process that lends itself well to producing mass volumes of products. There’s very little manual labor involved, keeping costs down.
Products made with injection molding
Because injection molding is so versatile, it can be used to make anything from doll shoes to car bodies. Here are some of the products most commonly produced using plastic injection molding:
- Toys: Everything from Barbie shoes to LEGOs are made by using plastic injection molding. LEGOs are a great example of how precise and versatile the process can be—every piece fits together perfectly.
- Household items: The plastic glasses you use out by the pool and the storage boxes you use to keep your sweaters safe from moths all owe their production to injection molding.
- Healthcare products: This is an industry that demands sterile, mass-produced single-use products to keep patients and doctors safe, which is why injection molding is ideal.
- Plastic bottles: When you buy a plastic bottle at the store, whether it’s used to hold water or cleaning products, chances are that plastic bottle was made by injection molding. These bottles are produced by the billions each year.
- Electronic casings and housings: Your laptop, remotes, TVs and more all use injection molding to create their housing.
- Agricultural products: Finally, the agricultural industry is jumping on the plastic bandwagon, since the material is more resistant to impact and humidity than the metal parts commonly used.
