At Ronningen Research, we provide the technical depth and manufacturing reliability that Bluff City innovators demand. We don’t just “press a button”—we engineer the future of your product.
Why Memphis Manufacturers Choose Ronningen Research
Memphis is a unique global hub. From the high-stakes logistics operations at FedEx to the precision manufacturing labs near the University of Memphis, local businesses face distinct challenges. High humidity in the Mid-South can impact polymer stability, and supply chain delays can stall a production line in an instant.
By utilizing our professional plastic injection molding services, you ensure that your products are built to survive both the field and the rigorous demands of global distribution.
The Benefits of Our High-Precision Molding:
Micron-Level Tolerance: We achieve the tight specifications required for precision medical parts and aerospace components.
Scientific Molding Protocol: Our data-driven process controls pressure, temperature, and flow, ensuring the first part is identical to the millionth.
Material Expertise: We work with medical-grade resins, high-heat polymers, and reinforced plastics designed for the most rugged industrial environments.
Logistical Superiority: Stop waiting for ocean freight. We provide domestic reliability that integrates seamlessly with Memphis’s “quadrimodal” transport infrastructure.
Scalability for Growth: From small volume injection molding for startups to high-capacity runs, we grow with your business.
Engineering Excellence: From Prototype to Bluff City Production
In Memphis, innovation moves at the speed of business. You might start with a concept in a local tech incubator and need a functional part by the end of the quarter. We offer a full-spectrum solution that eliminates the friction between design and delivery.
Diagnostic Engineering & DFM
Before we cut a single tool, we analyze your design for manufacturability (DFM). We identify potential sink marks, air traps, and stress points. Our rapid plastic prototyping allows you to hold a functional version of your part in days, ensuring your design is vetted before mass production.
Integrated Assembly & Finishing
A molded part is often just one piece of the puzzle. We offer comprehensive assembly and sub-assembly services, including heat staking, ultrasonic welding, and custom coloration. This allows your product to arrive in Memphis retail-ready or ready for final integration.
Success in the Mid-South: A Memphis Case Study
A few months ago, a medical device firm located near Germantown approached us with a significant challenge. They were producing a high-accuracy surgical housing. Their previous vendor, based overseas, was providing parts with an 11% failure rate due to inconsistent bonding in their overmolding process.
The Problem: The inconsistent parts were causing sterilization failures, leading to delayed clinical trials and skyrocketing rework costs. Furthermore, shipping delays at the Port of Savannah were threatening their launch deadline.
The Solution: Ronningen Research audited the project. We re-engineered the mold to optimize gate placement and implemented a scientific molding protocol. We utilized a climate-controlled facility to manage the Mid-South humidity that had previously been compromising the raw resin’s integrity.
The Result: * Scrap rates dropped from 11% to less than 0.3%.
The client reduced lead times by 8 weeks by moving to our domestic production model.
The device successfully cleared its final validation phase, allowing the company to meet their global launch window.
