Injection molding is a manufacturing process where small plastic beads, called resin, are melted down and injected into a mold that is the shape of the desired end product. Once inside the mold, the molten plastic gradually cools and eventually gets popped out by ejector pins. The end result is a strong, unified piece of plastic. Companies utilize injection molding to create plastic parts (such as gears for a clock) or complete products (such as lawn chairs).
Although alternative plastic molding processes exist, injection molding is an extremely efficient manufacturing process that produces parts within tight tolerances consistently over long periods of time. To give you an example, Lego bricks are injection-molded plastic, and they are nearly indestructible. You could put together and take apart two Lego bricks for 10 days straight before they broke. That’s about 37,000 times.
Injection molding is ideal for those seeking:
- Quick turnaround
- Low variability
- Long-term production runs
- Affordable and flexible prototyping
It is not ideal for those seeking:
- Extremely small part volume (sub-100)
If you’re unsure whether or not injection molding is the right manufacturing process for you, we have professional designers and engineers on staff who can analyze your needs and advise you on the best path forward.
We are an ISO 9001:2008 certified injection molding company that operates out of Cleveland, OH. There, we have a 50,000 square foot facility with 33 horizontal injection presses that boast clamping forces of up to 500 tons. With them, we frequently produce hundreds of millions of parts per year.
We enforce strict quality control on everything we make by utilizing the award-winning RJG platform to monitor all process variables during production to ensure optimal performance.
