Plastic Injection Molding: All There Is To Know | MPM

Nearly every industry produces plastic parts and components using injection molding. Think about all the small plastic pieces inside your car, each are so small and unique. They are also incredibly important to your car. You press these little plastic components to turn up the car’s radio or change songs. We take these small plastic buttons for granted, but they all come from somewhere. Someone has to make that small little radio button. And the person that does, makes it using injection molding.

What Is Plastic Injection Molding?

Plastic injection molding is the process of pouring hot or molten material into a rigid mold. The molten material, usually plastic, sometimes metal, cools and hardens into a solid component. This component is just one piece of a larger product. When all the different pieces are molded and set, the engineers and designers assemble the product using all the smaller pieces.

How Does Plastic Injection Molding Work?

Remember lego bricks? You can make an infinite amount of things with them. And, each small lego brick is one piece that makes up the whole project. Plastic injection molding works the same for all the other industries. How? The brilliant engineers at a company design their own highly specific versions of a lego brick. Then, they hire an injection molding company to make these small components. Finally, they take these new pieces and assemble something complex, like a radio or a computer. This process is what allows you to have such variety among all the products and goods available on the market today.

Why Should You Consider Plastic Injection Molding?

Plastic injection molding is perfect if you’ve got a plastic product that has multiple components. If you can break your product up into multiple pieces, then injection molding can speed up your assembly time and reduce on total costs.

However, if you have a very specific product, something that is too complex to be broken into moldable pieces, then injection molding won’t work for you. You will be better off refining your design and taking it somewhere to be 3D-printed.

3D-printing is also a great way to test prototypes of products. If your product is in the early days of development, then you don’t want to look into injection molding. First, you’ll want to perfect your prototype. Once it’s perfected, you can look into injection molding and get some estimates.

Specialists at the injection molding companies can reverse engineer your prototype into smaller pieces. Once you have the orders for thousands of your product, you can’t keep printing every one of them. It’s too expensive and typically unsustainable. Transitioning to injection molding can often save your company thousands of dollars and help you keep up with demand.
