The Different Industries that use Plastic Injection Molding
Plastic injection molding is used across a range of industries — from the tiny pieces holding together a child's toy, to the overhead buttons on an airplane. Chances are, when you see a plastic part, it was injection molding that brought it to life.
While millions of the plastic parts that exist in our daily life are created using this process, many of us don’t fully understand the scope of how wide the plastic injection molding process reaches. Below, we'll break down how plastic injection molding serves five key industries: industrial, consumer, aerospace and defense, automotive, and medical.
Industrial
Industrial environments are often harsh, exposed to chemicals and elements, and the machines and parts used experience repeated use. Manufacturers in the industrial sector need plastic parts that can withstand heavy use, chemical exposure, and repeated stress.
Yet these parts also need to be produced at scale without breaking the bank. That’s where plastic injection molding comes in: it allows this industry to produce complex, high-quality plastic components made from engineering-grade resins, at a reasonable cost without sacrificing quality.
The types of parts produced for the industrial sector include items like: gears, equipment housings and enclosures, valve components and fittings, machine safety covers, and bearings.
Consumer
When it comes to consumer product companies, it’s no secret that tight margins and quick timelines are a key factor in their manufacturing process. Plastic injection molding allows companies in this industry to produce plastic parts at high-volume, consistent quality, and at a low per-unit cost. These companies are still allowed the freedom of selecting aesthetic features like color, texture, and shape, but while maintaining a cost-effective production method.
Typical plastic parts produced in this industry range from household appliance housings, small pieces of a toy or board-game, packaging components, or furniture hardware (to name a few).
Aerospace + Defense
Aerospace and Defense industries require strict regulatory compliances and material certification standards for any plastic parts produced. Because the parts must be lightweight in order to improve performance and reduce fuel consumption, as well as be composed of materials that can withstand chemicals and harsh environments, there is no room for error. The plastic injection molding process is here to provide these industries with consistent plastic parts that meet regulatory requirements and quality standards, every time.
You can expect a plastic injection molding company to produce parts like interior cabin components, connector housings, structural clips, or protective cases for equipment.
Automotive
We’ve all been in a vehicle, but we all probably haven’t taken the time to notice the different sized plastic parts that make up the front of the dashboard. Ensuring these inside features are composed of plastic reduce weight of the vehicle, which in turn improves fuel efficiency and helps meet emissions standards. Plastic injection molding can provide volume and repeatability for these parts — where consistency, quantity, and quality are essential.
You can find plastic injection molding companies producing parts like radio buttons, dashboard features, connector housings, door handles, and more for the automotive industry.
Medical
Just like the aerospace and defense industry, the medical industry also requires extremely tight tolerances when producing plastic parts. Because of this, different injection molding manufacturers often specialize in different levels of medical injection molding production.
For example, a manufacturer producing parts that interact with the body, like a pacemaker, must meet far more rigorous facility requirements and comply with stricter regulations than a company producing a plastic part like a medical tray. At these higher levels, near-zero defect rates and sterile production spaces are mandatory in order to ensure every part meets the precision needed to protect patient safety.
Medical plastic parts include items like syringe barrels, IV components, surgical instrument handles, medical trays, and lab consumables.
Conclusion
From the toys we see on the shelves to the parts used in the vehicles we drive, the plastic injection molding industry has a hand in nearly every plastic part we interact with. Whether the priority is durability, cost-efficiency, precision, or regulatory compliance, this process continues to be versatile and essential to many businesses around the world.
