Jay Kumar on BusinessWest’s 40 Under Forty Class of 2015

President and Owner, Universal Plastics Corp.; Age 36

Jay Kumar

Jay Kumar spent nearly a decade on Wall Street as a proprietary trader for J.P. Morgan Chase, eventually rising through the ranks to executive director. He did very well for himself on ‘the Street,’ but there was something missing in terms of professional satisfaction, feelings that came to the surface during what Kumar called some “deep soul searching” when new financial regulations, specifically the so-called Volcker Rule, passed in the wake of the financial crisis of 2008, shutting down ‘prop trading,’ as it was called.“I was talking to my father about the idea of small-business ownership,” he recalled. “I did some thinking about it and liked the idea of buying and running a small manufacturing business.”

He talked further with a family friend who owned a few such ventures, and those discussions only whetted his appetite. That friend knew of an established Holyoke business, Universal Plastics, that was on the market.

In June 2012, Kumar purchased the precision thermoformer and has become a thoroughly hands-on owner with the operation. Since taking the reins, he has expanded the company through acquisition of Mayfield Plastics in Sutton in late 2013, while also introducing greater automation and adding new equipment that has increased efficiency and opened doors to new business.

The seismic career shift has been everything he anticipated, and more.

“I was excited by the idea of building something,” he told BusinessWest. “In my old career, I didn’t really get to build — it was much more about numbers and the computer screen; you never really saw what you were doing.

“Here, you could see we were making things; my first day here, they showed me the underside of a pool table they were making,” he went on. “You could see all these very tangible things that were being made, and that intrigued me.”

What also intrigues this father of two are the challenges to securing a qualified workforce for the years and decades to come. To that end, he has continued and expanded a long tradition of opening the doors to Universal Plastics to young people with the hopes that they might come to understand and then capitalize on the opportunities in the manufacturing sector.

“We try to encourage people to know what manufacturing is,” Kumar said, “and that it can be an exciting place to work — and a rewarding place to work.”

Jay Kumar on Plastics News Executive Forum 2015 Rising Stars Panel

Rising stars see plenty of room for growth in plastics

“Manufacturing is an incredibly promising field to young entrepreneurs. There’s a lot of innovation in plastics in particular.”

                             – Jay Kumar, President & Owner, Universal Plastics & Mayfield Plastics

By: Frank Esposito


LAKE LAS VEGAS, NEV. — The plastics industry’s rising stars rose to the occasion at the 2015 Plastics News Executive Forum — but they probably won’t be reading about it on Twitter.


Of the four-person panel, Kim Holmes said she was trying to use the social media network more, Michael Lipton said his firm had hired someone to do so, and Bryan Campbell and Jay Kumar said they barely used Twitter at all.


“I’ve read maybe six tweets in my life,” said Kumar, president of Massachusetts-based thermoformers Universal Plastics Corp. and Mayfield Plastics Inc. “I just don’t think you can say that much in 140 characters.”


The foursome — each age 40 or younger — also shared their thoughts on non-Twitter topics at the event, Feb. 4-5 in Lake Las Vegas.


“The younger generation is concerned about environmental issues,” said Holmes, senior director of recycling and diversion the Washington-based Society of the Plastics Industry Inc. “The two issues that come up about plastics are inconsistent access to recycling — which leads to the image that a plastic might not be able to be recycled — and plastics’ persistence in the environment. It can stay for a long time.”


At age 35, Kumar already is president of two firms. He and his father Sunil bought Universal in 2012 and added Mayfield in 2013. “Manufacturing is an incredibly promising field to young entrepreneurs,” he said. “There’s a lot of innovation in plastics in particular. Manufacturing tends to get overlooked, but there’s a lot of opportunity there.”


Lipton is director of plastics for the Arizona Pacific Plastics LLC business of recycling firm Recycle 1. That firm began in paper recycling before moving into plastics. “Paper recycling was easier than plastics, because it’s less complicated,” he said. “But we’re now recycling 30 million pounds of plastics per year. A lot of companies are still putting good [plastics] recycling material in the trash.”


Campbell, president of the southern division of injection molder Mack Molding Co., said that his firm is reaching out to younger people by working with high schools and offering internships. “We need to build for the future and set tangible goals,” he added.

Mayfield Plastics – A Medical Device Manufacturer’s Dream –  Design2 Part Magazine, Feb 2015


Mayfield Plastics’ is the subject of an article about Medical Device Manufacturing, entitled ‘Mayfield Plastics – A Medical Device Manufacturer’s Dream’. The article showcases Mayfield’s deep resume and expertise in medical device manufacturing and now, with joint ownership under Jay Kumar, Mayfield Plastics often partners with Universal Plastics to offer an extensive array of thermoforming capabilities, design & engineering support, and secondary services.

A Medical Device Manufacturer’s Dream

Highly cosmetic, pressure-formed parts that meet strict quality and functional requirements within tight

timelines are a specialty of a Massachusetts thermoformer, which often teams up with its sister company

to solve customers’ engineering quandaries.

By Mark Shortt

Experience, an attribute that medical device OEMs value highly in their suppliers, is something that

Mayfield Plastics offers in abundance. Mayfield, an ISO 9001:2008 registered manufacturer of custom

thermoformed parts, has been active in the medical device thermoforming space for over 40 years. During

that span, the company has partnered with medical device customers to design and manufacture parts used

in everything from medical lasers to X-ray equipment, bone density scanners, CT scan machines, and

MRI machines. Other applications have included medical carts, dental equipment, and custom medical

device packaging, such as clamshell containers for patients’ belongings, first aid kits, and syringe trays.

Since 2006, the company has been operating a 60,000-square-foot facility in Sutton, Massachusetts,

where it works with major medical OEMs to make a variety of housings, bezels, enclosures, panels, and

medical packaging, as well as medical trays and material handling products, among numerous others.

With the coming together of Mayfield Plastics and its sister company — Holyoke, Massachusetts-based

Universal Plastics — under the single ownership of Jay Kumar in 2013, Mayfield’s customers now have

access to the full resources of both custom thermoforming companies. Universal Plastics, known for its

in-house design capabilities, offers multiple in-house services in addition to thermoforming, including

painting, EMI/RFI shielding, and assembly

“Dual site capabilities allow us to meet all of our customers’ needs, provide excellent customer service,

and guarantee exceptional quality,” said Pia Kumar, Mayfield’s director of corporate development, in an

e-mailed response.

Mayfield’s custom thermoforming processes — thin and heavy gauge forming, vacuum forming, pressure

forming, and twin-sheet forming — are able to convert a sheet of plastic into a highly detailed finished

product with considerably less tooling investment than other plastic molding processes, such as injection


“As a supplier to OEMs, Mayfield Plastics’ biggest strength is our proven track record in high quality,

custom, complex medical device product manufacturing,” said Ms. Kumar. “Mayfield Plastics offers an

extensive resume in medical device parts manufacturing, and our expertise lies in manufacturing a custom

product suited to the customer’s specific performance or functional need.

“Our medical device customers are looking to us to design and/or manufacture a highly cosmetic part that

meets exacting quality and functional requirements,” she continued. “The look and feel is highly specific

to the branding and image the customer is looking to portray because usually, the parts we are

manufacturing are highly visible and critical to the aesthetic look of the overall medical device.”

Paul Davidson, sales engineer for Mayfield Plastics, said that when bringing a medical product to market,

medical industry OEMs typically express concerns over two main issues: the aesthetic appeal and

cosmetic aspects of the product, and the need for rapid turnaround.

“Typically, we’re seeing products that have been in development for a while, and now they’re finally just

getting around to doing the exterior, the housing pieces,” he said in an interview. “So we end up being the

one that has to hustle along trying to bring the project to completion. And, of course, a lot of these

medical devices are pretty sophisticated and sell for a pretty high price point. So, to go hand-in-hand with

that, they’re usually looking for a very modern, very high cosmetic level, with good aesthetics and a good

design concept behind it.”

The thermoforming process that’s most likely to be chosen for Mayfield’s medical equipment projects is

pressure forming, a process tailor-made for highly cosmetic parts. Pressure forming enables much sharper

detail to be achieved on thermoformed parts by increasing the forming pressure well beyond that which is

used in traditional vacuum forming.

“Pressure forming allows you to form the parts into a female mold, and the mold can actually be textured,

just like an injection mold would, so you can emboss the texture into the part during the forming

process,” said Davidson. “It allows you to form tight corners and do some modern design features, like

ribs and style lines, which seem to be in vogue these days.”

Kumar said that Mayfield Plastics offers all the services that its medical device customers need, from

product conception to market launch. The company’s in-house design engineers offer complete product

design support and can partner with the OEM customer to design the part. Its in-house tooling department

provides control over the entire process, allowing Mayfield to provide speed to market and guarantee the

tight timelines that are so important to medical device OEM customers.

On the manufacturing front, Mayfield provides a variety of services—from secondary operations to

accepting blanket orders that allow for KanBan type stocking programs for Just in Time deliveries—that

enable the company to operate as a turnkey, single-source contract manufacturing partner. The company

operates 3-axis and 5-axis CNC equipment for precise trimming of formed parts, and its roster of

secondary services includes complex assembly, as well as in-house finish painting, RFI/EMI shielding,

custom packaging, exact color matching, and drape forming. And consistent with its ISO certification,

Mayfield has a rigorous Quality Control department that employs a CMM to verify tooling against 3-

dimensional models before releasing the tooling for production. After production, parts are inspected for

conformance to quality standards.

“When a new customer comes to us, they want to know that they are working with a company with

experience, a company that understands the highly cosmetic and functionally exacting requirements of

this market,” said Kumar. “Along with Mayfield’s track record of successfully working with major

medical device OEMs, our in-house engineering, design services and tooling are important differentiators

for customers. Because Mayfield Plastics is able to provide comprehensive, end-to-end manufacturing

services, customers are guaranteed that consistency of quality and that control on every element of the

process will remain with them.”

Like Kumar, Davidson credits Mayfield’s in-house design, engineering, and toolmaking expertise as a

differentiator that enables the company to specialize in the type of complex, custom products required by

its medical device customers. Toolmakers on staff bring more than 100 years of cumulative experience to

their work. And by combining its engineering staff with that of Universal Plastics, its Holyoke, Mass.-

based sister company, Mayfield offers the mechanical and manufacturing engineering talents of six


“What you find these days is that a lot of companies are running lean and mean, and they don’t have the

expertise in the thermoforming business to know how to properly develop parts for thermoforming,”

Davidson said. “Also, they just don’t have the staff necessary to devote the manpower to getting designs

done themselves. So being able to just bring in a concept, or bring in some kind of an overview of what

they’re looking to do, and then hand it off to our crew to finish up the design and come up with a detailed

product, is pretty important.”

The company’s full-service, in-house design services include more than design assistance. Clients might

come to Mayfield with a framework that they’re looking to have covered, Davidson said, or with a napkin

sketch that needs to be developed into a thermoformable part that requires the creation of mounting points

and cut-outs.

“We can actually take the customer’s concept and do a design concept from that, and then develop it into

a 3D CAD model,” he said. “And we can send them the CAD model so they can do a test up with their

equipment before we finalize the design. So, as far as thermoforming goes, it’s a full-service design

house, actually, right in house.”

A major medical equipment OEM customer recently approached Mayfield with a design concept for a

new housing assembly for a new product. Operating on a limited budget, the customer was looking to

achieve a very specific overall appearance for the unit, which needed to be a highly cosmetic, complex,

multi-piece assembly with many accessory components. Working together with the customer, Mayfield

was able to develop and execute on an approach that met all of the exacting design and cosmetic

requirements while still coming in on budget and on time.

“Our in-house sales engineers and designers partnered with their designers to develop a solution

consisting of a combination of pressure formed panels, with a texture painted finish, [and] several access

panels fabricated from smoked acrylic,” said Kumar. “This included a large main acrylic panel with

several bends that needed to be precisely fabricated to match the contours of the mating, pressure formed

end panels.” Ultimately, Kumar said, Mayfield provided its customer with a turnkey solution within the

timeline of their new product launch.

Ellen Sora, an account executive with Mayfield, said that the company is able to provide what medical

device OEM customers value most in a supplier—“years of experience, the knowledge, the engineering

background, and a well-known history of making parts similar to what they’re looking for,” she said.

Davidson agreed, adding that “they’re looking for you to be cost competitive—not necessarily the lowest

cost, but it’s a combination of cost competitiveness, experience, reliability, and capability, and I think we

offer a very good balance with those items. We do just in time delivery for a good number of our medical

device companies, where we will manufacture parts on a blanket order basis and then deliver to them on a

weekly or on a monthly basis, based on their needs. So that way, they can get the pricing advantage of

placing a larger order, but they don’t have to carry the inventory until they need it.”

Mayfield’s location in Massachusetts is also advantageous for medical device customers, many of whom

are based less than an hour away in the Boston-Cambridge metropolitan area, well known as a magnet for

medical research, innovation, and entrepreneurship. About 65 to 70 percent of Mayfield’s customer base

comprises medical device clients, Sora said.

“Close proximity certainly helps,” she said, adding that “a lot of our customers like face-to-face visits and

meetings, to be able to sit down and actually discuss and work on their projects together as a partnership.”

Davidson said that close proximity is helpful for other reasons, too.

“A lot of companies these days like to pre-qualify their vendors, so they like to do site surveys before

they’ve chosen someone as a supplier, and being in close proximity certainly makes that easier,” he said.

“We find that if the customer is designing their own parts, being able to work with their designers and

come in and answer questions, and look at the units on their floor and talk to them hand-to-hand, face-to-

face, in terms of what their design concept is, how the panels are going to mount, how it’s going to mate

up with surrounding sheet metal components, what areas need to be covered, where you need

clearance—all that kind of thing is much easier to accomplish when you can do it face-to-face rather than

trying to do it long distance.”
