In Chicopee, Massachusetts, there is an unassuming red brick building that predates the existence of every modern golf OEM. From the outside, it could be confused for any other American manufacturing facility if not for the proudly displayed Callaway sign. Inside, there are over 400 hard-working people producing the highest quality golf balls using state-of-the art manufacturing techniques and tools — this red brick building is the Callaway golf ball plant.

To understand what you see when you first enter the ball plant, it’s best to first understand why it is here in the first place. When I initially asked this question to one of my tour guides, Vincent Simonds, the Senior Director of Global Golf Ball Operations, his answer started with a story that predated cars…it was at this point I knew that these guys mean business.

The modern history, however, starts in 2003 when Callaway purchased Top-Flite brand and subsidiaries, and with it purchased the entire Top-Flite manufacturing facility. In its it heyday, Top-Flite/Spaulding was producing its full line of clubs and balls out of this building, and that included equipment made for Bobby Jones. Chicopee, Massachusetts, was essentially the center of the golf club technology universe.

When its comes to balls, most modern golfers don’t equate Top-Flite with premium equipment or breakthroughs, but during this time period the ball plant in Chicopee was responsible for just as many technology and scientific breakthroughs as its modern Callaway self.

One Example is Bob Molitor. In 1972, Molitor developed the first two-piece golf ball with a Surlyn cover by combining the right amounts of various ionomers. This allowed golf balls to have much greater durability and along with it improved distance. This development is part of the reason the USGA had to establish the “One Ball Rule” because players would switch out depending on the hole since there was a huge distance advantage to this Solid Core Surlyn Cover design. Imagine that – the USGA having to change rules to accommodate a new technology, seems to me our current daily discussions about bifurcation aren’t something so new after all.

There were a lot of other great innovations over the years that lead to new technology making its way into the bags of players all over the world, one of which caused a revolution that we still benefit from today. In the 90s Top-Flite, under the Strata brand, cracked the code of merging the soft, high-spin “tour ball” performance with the lower-spinning, longer-flying, and more durable “distance ball”, this three-piece ball was like two balls in one. Strata’s design team accomplished this feat by placing a soft polyurethane cover on a Top-Flite distance ball, and then added a thin layer between the cover and the core that encased the ball’s already large and solid rubber core. In short, the modern golf ball was born. 

This brings us back to the modern day Callaway ball plant, a facility where the average employee tenure exceeds 20 years, and where every single premium Callaway Ball on the planet is made. The thing I quickly realized upon entering the plant for the first time is the pride every person has for their role in making world class golf balls. This sense of pride, and a friendly, yet hard-working environment is something I witnessed before at Callaway’s Carlsbad facility too — a testament to the company’s corporate leadership and the culture that they promote everyday. The “Victory Flag,” as they call it, was flying high thanks to Xander Schauffele’s win just a few days before my visit. 

The start of production begins with materials formulation

I was able to observe a pre-shift meeting, and you would think that based on the discussion of machine tolerances, quality control, & equipment inspections this plant is making parts for a yet-to-be-seen shuttle being sent into space, but they’re talking golf balls. Speaking to the tolerances the plant works within, the in-house machine shop had some amazing equipment, including some things I unfortunately could not share through pictures. This equipment works with the tolerances of less than the 1/30th the thickness of a Post-It Note. For example, each single side to a cover mold for the Chrome Soft line takes more than 30 hours of machine time to complete — an amount of time which might seem excessive, but when you think of the speed and forces impacting a golf ball from first driver strike and along its parabolic trajectory, we really are talking space shuttle physics.

Some of the most impressive equipment has nothing to do with the performance of the balls but rather how they look. I’m talking here about the Truvis patterned balls. What was perceived by many golfers at first as a gimmick (and something than even some Callaway management believed would be a fad) has proven to be an absolute slam dunk. The pentagon pattern provides a tangible benefit by creating an optical illusion that makes the ball look bigger (and easier to hit) especially out of the rough, and also gives visual feedback for short game shots and putting.

Let’s just say that what started as a toe dip with one machine has turned into an area of the plant with more than a dozen machines,  and Callaway is also producing Truvis balls with custom colors and logos — they’re not just printing pentagons anymore.

For actual production, every ball starts as raw materials, and compounds are precisely mixed in house, allowing Callaway to control the entire production process. The amount of materials engineering and chemistry I witnessed was way beyond what I was expecting, and to be frank, I went in with already high expectations. After initial mixing each batch is tested and sent to the next step.

Ever wonder why the cores of various golf balls from a single OEM are so bright and differently colored? It’s actually done to make each material identifiable in the process and give production staff another way to make sure materials get to the right manufacturing line. Of all the questions I asked, this one had the most simple answer.

The next step is the “cooking” process of the inner core. Each oven press is precisely controlled for pressure and temperature along multiple areas of each unit, this ensures a core that comes from the outer part of the press is formed and “cooked” to the exact same spec as one from the middle. The same process is used for both parts of the dual core.

Callaway utilized a proprietary manufacturing and molding technique to ensure exact specifications are met for centering the core and achieving correct cover thickness. Once the covers are in place, we officially have a golf ball, but we’re not done yet. There are still more quality control checks done by machine as well and humans to once again ensure each ball that leaves the plant is built to the highest quality standards and will perform just like the one before it.

Even the final paint and clear coat are highly engineered to resist staining, sheering, and stay on during deformation. To quote of one my tour guides, “The force applied to the cover and paint on the ball by a wedge would be like taking a hatchet to the paint on the side of your house.” It might seem like a simple process, but to ensure full coverage of sphere requires some pretty unique tools to get the job done.

This brings us to the new Triple Track Alignment system and how it was developed to help golfers play better. The new system helps improve alignment on putts from all lengths and it also happens to be on Callaway’s longest ball to date: the ERC Soft.

The alignment aid wraps 160 degrees around the ball and offers three parallel lines with high contrast (no more need to try and draw that long Sharpie line around your ball).  For those who choose to putt without the Triple Track alignment, Callaway considered you too, since the other 200 degrees around the ball unsure that you won’t see those lines from address.

Every shot taken means something to someone, whether it be a golfer trying to break 100 for the first time, or a tour professional lining up a putt on Sunday afternoon of a major championship. The golf ball is the one piece of equipment a golfer will use on every shot, and each person at the Callaway ball plant in Chicopee, Massachusetts, is proud to put their name behind it, even if you don’t see those names on the box.
