The company works in elastomers such as EPDM, butyl, natural and isoprene rubbers, and fluoroelastomers (Viton), among many others, as well as in silicone molding and polyurethane molding.
"We have our own chemist, so there are a lot of formulations that we have developed for customers over the years," he said. "This is a difference maker between us and competitors. We definitely buy some bulk rubber that is ready to rock and roll, but we have smaller lines where we develop FDA-approved material.
"All of this falls in line with our focus, running mid-volume, hard-to-make parts. That's our focus. We are not trying to be something that we are not."
With its cast polyurethane, Molded Dimensions can make parts anywhere between one gram and 60 pounds, with a max platen size of 24 inches.
"Our domestic presses are sized up to 24-inches square, and our GlocalSource presses have capabilities up to 60-inches square," Sprinkman said. "Cast urethane parts can range from very small, precision, compression-molded items to anything that fits in our 10-foot-square walk-in ovens."
Common products include PU wheels and wipers, rubber hose and tubing, bellows, bladders, bumpers, plugs and sleeves, protective boots and caps, buttons, rollers, seals, wheels, grommets and wipers, among many other products.
Molded Dimensions can custom design their PUs and rubber vulcanizates with thermal or electrical properties, and offers analytics on abrasion resistance; adhesion; creep and stress relaxation; and resilience/rebound.
The company's main markets include transportation, marine (port systems) and medical, though Sprinkman noted this "is a tough question to answer" as the company serves so many different spaces.
"Marine has been strong," he said, "as has all outdoor-related activity, like camping, power sports and utility vehicles. We had a strong exit from the pandemic because of our diversification.
"From 2020 to 2022 we are up 40 percent."
And Molded Dimensions witnessed many of the same supply line challenges that its competitors, customers and upstream suppliers in the industry have seen.
"A lot of it was people struggling with the supply chain, getting through as best they could," Sprinkman said. "And for awhile, we were similar to everyone else. Oddly enough, about three to five months ago was the worst era of getting materials.
"It is frustrating because we had the orders, if we could just get the material. There is no worse feeling in the world than when you tell a customer parts will be delivered on 'x' date, and they get delayed. We were running hand-to-mouth—there was nothing that was sitting on shelves.
"We pride ourselves on customer service, and we are not a highly automated company, which is why the onboarding process is so important. We produce quality products, and on time. When that becomes problematic, it is a difficult pill for us to swallow as that is what we pride ourselves on."
