From a production standpoint, the compact tooling minimizes residence time for the expensive, heat-sensitive resins RenyMed uses to mold precision medical components.

“Because it’s modular, we’re starting from the 40-yard line in terms of design,” says Raiken. “We’re getting a running start on the project.” As an example, he displays one part for which RenyMed was able to create tools for six different sizes in seven weeks.

“We make the most contained and concise mold,” Raiken says. “So, when we use this tooling, what we’re doing is asking, ‘What does the part require?’ rather than fitting the part into something we know.”

Raiken knows molds, having started a one-man tool shop in the mid-1980s after completing a moldmaking apprenticeship. That operation was carved out of unused space in the corner of an injection molder, and consisted of a mill, grinder, and lathe. Dissatisfied with the mold testing he was finding, Raiken decided to add a molding machine, which he did in a new space all to himself.

Raiken expanded his 911������ from there, taking on molding and growing along with the California medical-device market, which called for high-precision parts made from difficult materials in a race to the smallest that continues today. Ten years ago, RenyMed moved into its current space in Baldwin Park.

Raiken notes that most of the parts he makes weigh less than a gram. Exemplifying the small size and precise nature of the programs RenyMed takes on, when Plastics Technology visited, Raiken was preparing for a customer visit to discuss a new ophthalmology product used to hold the iris open during cataract surgery. For this project, as with well over 90% of its jobs, RenyMed will help design the tooling it will build and run.

“Our niche is creative DFM [design for manufacturing]. We provide our customers with creative manufacturing solutions that help them realize their medical device,” Raiken says. “At trade shows, molders lay out hundreds of parts, to say, ‘That’s what we do, we make plastic parts.’ Well that’s not what we do. We provide our customers with the ability to make their product.”
