Helping a Seacoast Startup Scale
Last year, a small medical device team located near Henry Law Park in Dover reached out to us. They had a brilliant design for a handheld diagnostic tool but were struggling with high failure rates from their previous molder. They were concerned that a partner with Michigan-based operations would be “too far away” to handle the nuances of their project.
We proved them wrong. Through daily video check-ins and overnighted samples, we served their Dover-based team as if we were just down the street.
The Solution: Our engineers identified a flaw in the original mold design that caused stress fractures. By utilizing our custom plastic injection molding services, we redesigned the cooling channels in the tool.
The Outcome:
Zero Defects: Their failure rate dropped from 12% to 0%.
Faster Launch: They beat their projected market launch by three weeks.
Seamless Logistics: We managed the entire custom packaging and shipping process, delivering finished units directly to their distribution center.
Today, that Dover company is a leader in their niche, and Ronningen Research remains their exclusive manufacturing partner.

Frequently Asked Questions
Why shouldn't I use a local Dover molder?
While local is great for some things, Ronningen Research offers a level of specialized precision and “all-under-one-roof” services—like electroplating and ultrasonic welding—that many smaller shops cannot match. We serve Molding in Dover, NH, with the resources of a national leader.
What materialsHow do you handle shipping to New Hampshire?are used in plastic injection molding?
We treat the distance as a non-factor. Our logistics team is expert at moving freight across the country. Most Dover clients find that our shipping times from Michigan are comparable to moving goods across New England.
What materials do you work with?
We work with a vast array of resins, including ABS, Polycarbonate, PEEK, and glass-filled nylons. If your part needs to survive a Dover winter or a high-heat engine environment, we have the material expertise to help.
Do you offer low-volume production?
Absolutely. We specialize in bridge tooling and small-batch runs, which is perfect for Dover startups testing the market before committing to millions of units.
The Risks of Ignoring Quality Molding
In the competitive landscape of the Seacoast, a single batch of bad parts can ruin your reputation. Risks of using subpar molding services include:
Part Warping: Especially problematic in Dover’s fluctuating humidity.
Flash and Burrs: Poorly maintained tools leave unsightly plastic edges.
Short Shots: When the plastic doesn’t fill the mold entirely, leading to structural failure.
Avoid these headaches by partnering with a proven leader. We serve Molding in Dover, NH, with a commitment to “Right the First Time” manufacturing.
