At Ronningen Research, we provide High-Quality Plastic Injection Molding Services for Warwick, RI Businesses that bridge the gap between complex engineering and local reliability.
Whether you are a medical startup near Kent Hospital or an aerospace supplier operating out of the Hillsgrove neighborhood, your components must meet exact specifications. Inconsistent quality isn’t just a nuisance; it’s a threat to your bottom line.
The Warwick Manufacturing Challenge: Why Precision Matters Locally
Warwick businesses often face a common hurdle: finding a domestic molder who can handle high-precision requirements without the lead-time delays of overseas shipping. Many local companies struggle with:
Environmental Factors: Our Rhode Island climate can affect polymer stability during the molding process if not managed in a climate-controlled facility.
Supply Chain Bottlenecks: Relying on distant suppliers can stall production lines at Quonset Point or Warwick industrial parks.
Quality Variations: Outdated tooling leads to “flash” or structural weaknesses, which are unacceptable for high-stakes industries like precision medical parts.
Our Expert Process: From Concept to Warwick Delivery
We don’t just “press a button.” Our process is rooted in scientific molding principles to ensure that every part—from the first to the millionth—is identical.
1. Design for Manufacturability (DFM)
Our engineers review your CAD files to identify potential issues like sink marks or air traps before a single drop of plastic is melted. We offer rapid plastic prototyping to test fit and function in real-world Warwick applications.
2. Custom Tooling and Mold Construction
Using low-cost tooling options, we create high-strength molds designed to withstand the rigors of high-volume production. We specialize in complex techniques like insert molding for parts requiring metal reinforcements.
3. Precision Injection Phase
We utilize state-of-the-art electric and hydraulic presses. Our facility monitors temperature, pressure, and velocity in real-time. This is critical for Warwick’s electronics and aerospace sectors where a fraction of a millimeter is the difference between success and failure.
4. Secondary Operations and Assembly
A finished part often needs more than just molding. We provide a full suite of assembly and sub-assembly services right here, saving you the hassle of coordinating multiple vendors.
