The other arm of Rogan’s growth strategy is two-shot molding. “We were pushed into it by one of our biggest customers,” says executive v.p. David Schoessow, who has been with the company for 34 years. “They wanted soft-touch knobs. We did two-shot even before we had tried insert overmolding.”

An example of two-shot, hard/soft molding is a child’s dinnerware set of PP and TPE. Another is a smartphone cover of TPU molded on TPU—two colors and durometers—with an insert of a thin PC ring for the phone’s camera window. What’s notable about these parts is that they are both examples of “reshoring” jobs that had been outsourced to China. They came back here because of issues with quality and logistics—transportation time and cost, according to Ritzema. “We’re even shipping some parts to China,” he adds. That’s because medical OEMs are more comfortable with domestic manufacture.

Processors with sustainability goals or mandates have a number of ways to reach their goals. Biopolymers are among them.

Today, two-shot molding is around 40% of Rogan’s business (including some dial and knob applications), and nine of its 34 thermoplastic presses have two-shot capability.

Despite price increase nominations going into second quarter, it appeared there was potential for generally flat pricing with the exception of a major downward correction for PP.

Another LSR overmolded part is a medical device (cervical seal) consisting of a section of thin PC tubing with 5-6 mil LSR fins molded onto it. Another part (lung catheter) is a 30-in.-long tube of Pebax TP elastomer from Arkema with an LSR finned “bumper” molded onto the end. A tiny button-sized device that is actually a miniature microphone consists of stainless steel and Ultem encapsulated in LSR. Another developmental medical part (arterial shunt) consists of a stainless-steel spring overmolded with two separate shots of LSR.

Take a deep dive into all of the various aspects of part quoting to ensure you’ve got all the bases—as in costs—covered before preparing your customer’s quote for services.

Second quarter started with price hikes in PE and the four volume engineering resins, but relatively stable pricing was largely expected by the quarter’s end.

Additive manufacturing (AM) is great for plenty of applications, but it does have some disadvantages when it comes to certain areas. Industrial 3D printers may be able to build enough parts in one batch, thanks to a large build envelope, to make mass manufacturing worthwhile, but desktop AM systems are less useful for such applications.

Resin drying is a crucial, but often-misunderstood area. This collection includes details on why and what you need to dry, how to specify a dryer, and best practices.

Mixed in among thought leaders from leading suppliers to injection molders and mold makers at the 2023 Molding and MoldMaking conferences will be molders and toolmakers themselves.

While prices moved up for three of the five commodity resins, there was potential for a flat trajectory for the rest of the third quarter.

LSR accounts for only about 10% of Rogan’s current sales, but that share could soon double, because 40-50% of its new business is in LSR, says Robert Flammini, v.p. of sales and marketing. “LSR and two-shot molding are the areas we want to grow in,” says Ritzema. “We don’t want to compete in commodity molding.”

LNS Technologies is looking to fill the gap between AM and injection molding for small runs of plastic parts by offering a desktop plastic injection molding system. Already fully funded via Kickstarter, the company plans to sell its system for $1,500, which is cheap for nearly any injection system that isn’t fueled by Play-Doh.The PIM-SHOOTER Model-150A offers a mold size of up to 7 x 5 x 5 in. with a shot capacity of 1.25 cu. inch volume or 21 grams weight. The machine can handle ABS, PE, PP, PS, ACETAL, EVA, and TPE plastics and has a footprint comparable to one of those can smashers people bolt to their walls.Although users will still have to get molds made to use the machine, the ability to pop out a small run of plastic objects without waiting multiple hours for a desktop 3D printer to finish a single print could make the LNS Technologies’ offering a useful tool for trial runs of products or offer greater capacity to small manufacturers and colleges.From the Kickstarter page:So what our machine offers is a way for individuals, small businesses or even large companies to use low cost aluminum molds to produce their own prototype partsff.  Or they can even make moderate production runs of a custom plastic product.

From compression molding phenolic knobs and dials to overmolding liquid silicone rubber onto metal and thermoplastics, the 78-year history of the Rogan Corp. is full of twists and turns—what chairman Edward Rogan calls “transformations” in his decade-by-decade narration on the company’s website (rogancorp.com). But one consistent theme stands out—an adventurous and inventive spirit that has put Rogan on the leading edge of a number of important trends in plastics—and even on the frontiers of space exploration.

Meanwhile, LSR adhesion to metal “still has a ways to go,” in Ritzema’s opinion, “especially for small parts with little surface area to bond to. We’ve tried primers. We’ve tried plasma treating metal, but it didn’t help.”

In this three-part collection, veteran molder and moldmaker Jim Fattori brings to bear his 40+ years of on-the-job experience and provides molders his “from the trenches” perspective on on the why, where and how of venting injection molds. Take the trial-and-error out of the molding venting process.

“We’re bidding on bigger jobs now,” says Flammini, “so we’re looking at bigger machines for more cavities.” Rogan wants to go smaller, too. It has ordered a 20-ton Sodick press with a 14-gram shot capacity to mold smaller thermoplastic parts.

While the melting process does not provide perfect mixing, this study shows that mixing is indeed initiated during melting.

Rogan’s growth in medical molding is spearheaded by a new 1500-ft2, Class 100,000 clean room that houses four LSR molding machines, both horizontal and vertical.

“We began strategic planning for an entry into LSR in 2003,” recalls Ed Rogan. “That was just after the SARS epidemic hit. We saw the trend in hospitals to replace devices in contact with patients more frequently, such as every eight hours instead of once a day. That made it more economical to purchase more costly but re-sterilizeable components instead of disposables.”

The key to Rogan’s success in LSR overmolding has been the arrival of “bondable” silicones that adhere well to thermoplastics. Rogan has formed a close relationship with its main LSR material supplier, Shin-Etsu Silicones, which has helped it deal with adhesion issues. Though bondable LSR works well with thermoplastics, there still can be occasional problems. In one case, Rogan was buying a polycarbonate part from another molder and found that overmolded LSR was not adhering as expected. The culprit turned out to be mold release on the PC part.

Today, Rogan Corp. is a $10-million business with some 65 employees in a 45,000-ft2 plant in Northbrook, Ill. Rogan specializes in liquid silicone (LSR), two-shot, and insert molding for medical, electronic, aerospace, telecommunications, appliance, lawn/garden, and sports/recreation industries. But while it is pursuing some of the hottest areas of injection molding innovation, Rogan also remains tied to its roots.

Rogan quickly became expert at molding LSR with very tight tolerances and difficult shapes. “Customers are always pushing the limits,” says Ritzema. “They ask us, ‘How thin can you go?’ We have molded a 4-mil LSR bottom onto the PC rim of a petri dish 3 inches in diameter,” says Ritzema. “We can hold half a mil tolerance on an 8-mil-thick diaphragm that’s overmolded onto a PC rim. We’re also one of the few firms with experience in molding optical-grade LSR.”

How does Rogan keep abreast of this fast-moving area of technology? Ritzema responds, “We read, go to seminars, do as much investigating as possible. We discovered Sodick at a trade show. And we have learned a lot from the LSR materials people, who helped us through a lot of adhesion problems.”

Plastics Technology’s Tech Days is back! Every Tuesday in October, a series of five online presentations will be given by industry supplier around the following topics:  Injection Molding — New Technologies, Efficiencies Film Extrusion — New Technologies, Efficiencies Upstream/Downstream Operations Injection Molding — Sustainability Extrusion — Compounding Coming out of NPE2024, PT identified a variety of topics, technologies and trends that are driving and shaping the evolution of plastic products manufacturing — from recycling/recyclability and energy optimization to AI-based process control and automation implementation. PT Tech Days is designed to provide a robust, curated, accessible platform through which plastics professionals can explore these trends, have direct access to subject-matter experts and develop strategies for applying solutions in their operations.

These smartphone cases consist of two-shot molded TPU on TPU in different colors and durometers, with an inserted PC ring that forms the camera window. This job was “reshored” from China.

Sustainability continues to dominate new additives technology, but upping performance is also evident. Most of the new additives have been targeted to commodity resins and particularly polyolefins.

Formnext Chicago is an industrial additive manufacturing expo taking place April 8-10, 2025 at McCormick Place in Chicago, Illinois. Formnext Chicago is the second in a series of Formnext events in the U.S. being produced by Mesago Messe Frankfurt, AMT – The Association For Manufacturing Technology, and Gardner Business Media (our publisher).

Right from the start, Rogan jumped into LSR overmolding onto stainless steel and thermoplastics like PC, PC/ABS, nylon, PBT, and Ultem polyetherimide (PEI). At present, all such jobs involve insert overmolding the thermoplastic or metal component, though true two-shot thermoplastic/LSR molding is the logical next step for high-volume jobs. The company is even looking into two-shot LSR-on-LSR molding. “It’s not easy to do soft on soft,” cautions Ritzema. “Shutting off steel on a soft material is tricky.”

Exhibitors and presenters at the plastics show emphasized 3D printing as a complement and aid to more traditional production processes.

Rogan buys Sumitomo Demag presses for one- and two-shot thermoplastic molding. “Without experience in this field, it’s hard to buy a two-shot machine,” says Ritzema. There really is no ‘general-purpose’ model. A lot of two-shot jobs are very specific, and there are so many different types of machine and tooling design. You could spend $500,000 on a machine that might not work for half the jobs out there.” Rogan gains an edge in two-shot molding from its proprietary mold designs. Explains Ritzema, “We have hundreds of modular mold bases that allow us to load cavity and core inserts for different jobs from the mold face. It adds flexibility and reduces tooling cost. We also have a proprietary rotating mold base.”

LSR is the key to its medical market focus. “LSR can be autoclaved,” notes Ritzema. “It has low compression set, and its flexibility allows it to be demolded from large undercuts on both cavity and core sides.”

One of Rogan’s customers is developing a home dialysis device that is PC with eight small TPE bladder inserts. These are overmolded at present but eventually will be in two-shot production.

Across the show, sustainability ruled in new materials technology, from polyolefins and engineering resins to biobased materials.

Medical is Rogan’s main growth target. It accounts for the installation of the company’s first “hard” clean room, with 1500 ft2 devoted entirely to LSR molding and assembly. Previously, Rogan used some portable, soft-sided clean-room machine enclosures and may use them again, though it is already planning a Phase II expansion of the permanent clean room.

Additive technology creates air pockets in film during orientation, cutting down on the amount of resin needed while boosting opacity, mechanical properties and recyclability.

Rogan’s first exposure to plastics in the 1930s was hot stamping (a process it claims to have invented) of knobs and dials for appliances.

In 1982, Rogan pioneered the new field of multi-material or two-shot injection. This led to hard/soft overmolding of TPE onto rigid thermoplastics—another headstart in what is now a booming specialty. In 1991, Rogan was one of the early practitioners of gas-assist molding. The latest “transformation” was Rogan’s 2006 entry into liquid silicone—jumping right into overmolding LSR onto stainless steel and polycarbonate (PC). And just this year, the company built a Class 100,000 clean room to house its four horizontal and vertical LSR presses.

One of Rogan’s specialties is overmolding LSR onto metals and thermoplastics. Inset: This medical part consists of a thin PC tube overmolded with LSR fins 5-6 mils thick.

LSR is the fastest-growing business sector at Rogan, fueled by expertise in bonding silicone to thermoplastics (PC/ABS in left photo).

The aim of this presentation is to guide you through the factors and the numbers that will help you determine if a robot is a smart investment for your application.

“We’re building up our design capability,” adds Ritzema. “We already understand design for manufacturability, and we can evaluate customers’ designs for potential tooling, molding, and assembly problems. We help to design for automation where possible.” This knowledge is especially vital in LSR jobs. “Few customers understand LSR design. They don’t realize how it can flash through half a mil gap.”

In 1946, the company acquired three war-surplus compression molding presses and began making its own phenolic knobs and dials. Ed Rogan II, son of one of the founders (and now the sole owner), joined the family enterprise in 1949 at six years old, earning a Chicago Cubs game ticket for inserting 5000 screws in a 6-hr shift, doubtless violating all sorts of child-labor laws by today’s standards.

In 1967, the firm bought its first injection machines and began insert molding plastic over metal. In 1969, Rogan Corp. received a commendation from the U.S. government for its contribution to the first moon landing. “We believe we had a knob on the instruments that collected or analyzed moon rocks,” Ed Rogan explains.

Plastics processors are finding applications for 3D printing around the plant and across the supply chain. Here are 8 examples to look for at NPE2024.

Successfully starting or restarting an injection molding machine is less about ticking boxes on a rote checklist and more about individually assessing each processing scenario and its unique variables.

“We want to get bigger in contract manufacturing,” says Bob Flammini. “OEMs want a single supplier for a full turnkey package. We can supply molding and pad printing, hot stamping, heat staking, ultrasonic welding, kitting, and packaging. We want to be a total solution provider.”

While prices moved up for three of the five commodity resins, there was potential for a flat trajectory for the rest of the third quarter.

The appliance industry eagerly embraced this new method for decorating plastic knobs and dials as a replacement for time-consuming engraving and “paint-and-wipe” methods. Throughout the 1930s and ’40s, Rogan Brothers thrived in marking plastic knobs and military equipment, such as dials for gun turrets.

In this collection, which is part one of a series representing some of John’s finest work, we present you with five articles that we think you will refer to time and again as you look to solve problems, cut cycle times and improve the quality of the parts you mold.

Across all process types, sustainability was a big theme at NPE2024. But there was plenty to see in automation and artificial intelligence as well.

While pinning much of its growth strategy on LSR, Rogan acknowledges that competition is growing in this area. Ritzema thinks the LSR market is expanding enough to accommodate new players. “The greatest difficulty in getting started in LSR,” he says, is finding experienced people. Until recently there were no school programs for LSR engineering.”

After completely filling the classroom last year, the Silicone Elastomers Technology and Fabrication course returns to Pomona, Calif. Jan. 31-Feb. 3.

Then and now: In 1946, Rogan Corp. began compression molding phenolic knobs and dials for appliances. Today, Rogan is clean-room molding LSR, including overmolding of metal and thermoplastics on this vertical Sodick press.

Today’s Rogan Corp. is a mix of old and new. Dials and knobs remain 65% of its business. Three thermoset compression molding presses still get some use. “We’ve been making some of these products for as long as 40 years,” says Operations director Jim Ritzema. “They still pay the bills.”

The three Rogan brothers left Winnipeg, Manitoba, in 1927 to seek their fortune in Chicago. They founded Rogan Brothers Co. in 1934, providing calligraphy services to retailers, schools, and churches. They broke into plastics in 1937—on a wager. A business acquaintance bet Nick Rogan a fifth of whiskey that he couldn’t invent a process for decorative marking on plastics. By 4:00 AM the next morning, Nick had come up with a “branding” technique that family legend holds to be the origin of what is now called hot stamping.

Rogan started out in LSR with a Nissei press but now prefers Sodick Plustech machines because it finds their V-Line two-stage screw/plunger injection system to be more precise, since there’s no check valve to leak. One of its presses is a 150-tonner, which is on the large side for LSR. The Sodick machines are electric/hydraulic hybrids, but Rogan may look into all-electrics in the future. Rogan uses LSR mixing/metering systems from Fluid Automation, Inc. While Rogan works with several moldmakers that specialize in LSR (M.R. Mold, Kingson Mold, and Roembke), Rogan uses its own cold-deck design. All its LSR molds use cold runners to avoid discarding cured waste that costs $8 to $13/lb.
