Rapid injection molding, also known as RIM, has been around for many years. It is being used in the manufacturing of products like automotive components, plastic toys, and even medical devices.
RIM provides many benefits over other manufacturing processes and is often used by companies that want to reduce the cost and complexity of the production process or want to increase the speed at which they can get their products out on the market.

What is Rapid Injection Molding (RIM)?
Mold is milling begins immediately after CAD models are sent to the production floor via RIM. Aluminum is typically used in mold fabrication, rather than steel. Compared to traditional steel molds, this method allows for faster and more affordable tooling.
As well as simple overmolding and insert molding, RIM can accommodate side-action and hand-load inserts. Electrical discharge machining (EDM) can be used to improve the corners and edges of molds. Different surface finishes can also be applied. This means rapid injection molding is able to produce plastic parts in a matter of weeks rather than months, as with traditional injection molding methods.
The benefits are obvious: creating complex parts in less than an hour can dramatically increase profit margins and production efficiency. But there are many factors to consider before making a final decision on whether or not RIM is right for your company.
Why should I consider Rapid Injection Molding?
Rapid Injection Molding (RIM) is a viable option if you want to create parts, tools, or jigs quickly and economically. If you have a 3D model of your part and need it to be replicated in a short period, then RIM could be the perfect solution for you.
In addition, RIM can create complex parts that are near impossible to produce via traditional manufacturing processes. This method can also reduce material costs by 50% when compared with traditional machining methods such as CNC milling or turning.
The process does not require the expensive tooling like traditional injecton molding, so its’ risk of tooling equipment investment is minimized. Rapid injection molding is capable of producing a few hundred parts per day—an amount many small businesses can easily justify.
Why consider Rapid injection molding for your project, the first factor is about money we talked before, the second factor is about the quantity, RIM is a good way for low-volume production.
What are the benefits of using RIM as a manufacturing process?
There are various benefits associated with the RIM process and they include:
More accurate components: Components manufactured using RIM process are more accurate than those produced via 3d printing. Besides, RIM produced plastic parts with better surface finish.
Faster production rate: Components manufactured through RIM process can be produced in less time compared to other traditional manufacturing methods.
Economical process: Parts made through RIM can be made economically. The cost of tooling is also low which makes it easier to manufacture large quantities of parts.
Dimensional accuracy: Dimensional accuracy is improved when parts are made through the RIM process. This method provides high dimensional accuracy along with a good surface finish.
High reproducibility: Parts manufactured through RIM have high reproducibility because each component undergoes an identical thermal cycle throughout its life. So any change in dimension will be uniform throughout all cross-sections of a component.
Better mechanical properties: Mechanical properties such as tensile strength, hardness, elongation at break, etc., can be easily controlled by altering some processing parameters like temperature or pressure.
How can I ensure the quality of my parts and reduce costs during tool build and maintenance cycles?
Production tooling is expensive and can be difficult to change. As a result, it’s important to consider every aspect of your part during design and development—because what you learn may dictate whether or not you should use rapid injection molding as part of your process.
Rapid injection molding allows manufacturers to produce parts in hours rather than days or weeks, but it comes with its own set of considerations. For example, if your product requires an intricate shape that can’t be made using traditional manufacturing methods, rapid injection molding might be a good fit for your production needs.
But, if your products require high-quality finishes or complex internal features, rapid injection molding may not be appropriate.
Additionally, if you need to make frequent changes to your molds due to changing customer demands or product upgrades, then rapid injection molding might also not be right for you because new molds will have to be built each time there’s a need for a modification.
