Request High-Precision Plastic Injection Molding in Boise, ID
Boise is currently experiencing a massive surge in technological and industrial growth. From the semiconductor giants along Federal Way to the emerging ag-tech startups in the Treasure Valley, the demand for high-quality components has never been higher. However, many local innovators face a significant hurdle: a shortage of specialized, high-precision manufacturing capacity within the state. When your production relies on microscopic tolerances, a generalist shop simply won’t suffice.
At Ronningen Research and Development, we fill this critical gap. We serve Boise, ID from our Michigan-based operations, bringing the elite engineering heritage of the Midwest to Idaho’s growing tech sector. By serving the region from our Michigan facility, we provide national-scale resources and advanced custom plastic injection molding services that ensure your project transitions seamlessly from design to delivery.
Expert Manufacturing Process: From Michigan to the Treasure Valley
Navigating the complexities of plastic production requires a disciplined, professional approach. While we serve clients throughout Boise, ID, every stage of our physical production occurs at our state-of-the-art Michigan headquarters. Here is how we ensure professional results for your Idaho-based project:
1. Technical Design Review
Our engineers analyze your CAD files to identify potential molding issues before they become expensive mistakes. We look for uniform wall thickness, draft angles, and material compatibility specific to Boise’s high-desert climate, where temperature swings can impact plastic stability.
2. High-Precision Tooling
We utilize advanced CNC machining to create durable, accurate molds. For companies looking to manage initial capital, we offer low-cost tooling for plastic parts without sacrificing the tight tolerances required by Boise’s aerospace and medical industries.
3. Scientific Injection Molding
Our Michigan-based operations utilize decoupled molding techniques. This process separates the filling, packing, and holding stages to ensure that every part—from the first to the fifty-thousandth—is identical.
4. Secondary Operations and Assembly
We provide a total solution by offering plastic injection assembly services. Whether your part needs heat staking, ultrasonic welding, or custom labeling, we handle the complexity at our facility so you receive a finished product ready for the Boise market.
Professional Service Benefits: Solving Idaho’s Production Challenges

Frequently Asked Questions
How does shipping work from Michigan to Boise, ID?
We have established a robust logistics network that treats the distance as a non-issue. Parts are securely packaged and shipped via rapid freight. Most Boise clients find that our efficiency in Michigan actually results in faster total lead times than local shops that are backlogged.
What industries do you serve in the Boise area?
We serve a diverse range of sectors, including medical device manufacturing, renewable energy, consumer electronics, and agricultural technology. Our Michigan-based operations are equipped to handle the high-tech requirements of the Boise Research Center and beyond.
Can you handle small-volume production runs?
Yes. We specialize in being a flexible partner. While we have the capacity for high-volume production, we also offer small-volume injection molding services for specialized Idaho projects.
What are the main factors that affect the cost?
The primary cost drivers are the complexity of the mold, the type of resin selected, and the total volume of the run. We provide transparent, itemized quotes to help you understand exactly where your investment is going.
Why shouldn't I just use a 3D printer for my parts?
3D printing is great for initial concepts, but it cannot match the strength, finish, or material properties of injection molding. For any part that needs to perform in the field or be sold to a customer, molding is the professional standard.
