Growth is usually treated as a good problem for a manufacturer to have, but it also forces change. For small manufacturers, that often means modernizing how they plan, process, and coordinate work.
Growth puts pressure on parts of a manufacturing operation that may have worked perfectly well at a smaller scale. As orders increase, informal routines become harder to manage. A shop that once built a few products at a time may suddenly need to produce repeatable parts in volume, keep finished inventory on hand, and still handle the outside work that helped build the business.
That is what happened as Catawba Attachments began growing inside Eddie's Welding, Inc. in North Carolina. The company had equipment, floor space, and people. What changed was how much coordination was required to keep it all productive.
We started growing fast, much faster than we had anticipated. The challenge became figuring out how to work attachment components into an existing fabrication schedule without starving either side of the business for parts.
That experience illustrates one of the first lessons small manufacturers learn as they grow: adding production capacity does not eliminate the need for planning. It makes planning more important.
When the Bottleneck Moves
At lower volumes, a manufacturer can often compensate for an inefficient process with experience and effort. Someone walks across the shop to find a bin. A fabricator stops what he is doing to repair a customer's broken part. An operator cuts tubing on a saw, measures each piece, drills it, and moves it to another machine.
Each interruption may seem manageable on its own. At higher volume, they add up.
Mark Farnsworth said one of EWI's longstanding traditions is helping walk-in customers with small repairs. That service helped build the company's reputation, but it could also disrupt scheduled production.
Pulling a fabricator away from a job for an hour to handle an unexpected repair does not necessarily cost only an hour. By the time the employee stops one job, changes tasks, and gets the first job moving again, the interruption can consume considerably more production time.
I described a press-brake process in which an operator would bend components, place them on a pallet, and later locate the proper rack or bin for those parts. The company eventually stepped back and realized it was handling the same material twice.
Its solution was not another expensive machine. It built a second set of storage racks and changed the procedure so the press-brake operator could place completed parts directly where they belonged. Not every capacity problem requires another employee or another machine. Sometimes the best investment is a better process.
A $1.2M Change in Thinking
Other bottlenecks do require technology. For EWI, the most significant change came with the purchase of a TRUMPF tube laser. I'd put the investment at approximately $1.2 million, but the machine changed much more than the speed at which tubing could be cut.
Before the tube laser, producing a component could require a worker to load material into a saw, measure and cut each piece, then move the components into additional drilling or milling operations. The tube laser can combine several of those operations, but the bigger advantage is downstream.
If the cutting department can stay ahead of fabrication, welders are less likely to wait for components. EWI now tries to keep enough processed parts available to build approximately 10 units of an individual Catawba attachment.
Instead of cutting everything after an order arrives, the company can use capacity during slower periods to build a buffer for future production. That buffer has become increasingly important as customer expectations have changed.
Catawba currently maintains roughly 263 finished pieces of equipment in inventory. The reason is simple: customers have become accustomed to fast fulfillment. If the product is not available, the customer may find someone who has it.
Digital Manufacturing Starts Before the Machine
Modernization is also changing what happens before material reaches the shop floor. Design engineer Michael Foster develops products in SolidWorks with the manufacturing process already in mind.
Because the company's laser processes can hold tight dimensional tolerances, Michael can design tabs, slots, holes, and other production details into the parts themselves. Those details can eliminate measuring and layout during assembly.
A hole that would once have been drilled later can already be in the part. Two components that once required a fabricator to measure their position can be designed to locate themselves.
Even small design changes can affect production. Changing a plate's geometry may improve how several parts nest on a sheet and reduce material waste. Adding tabs can reduce layout time. Moving a hole into the CNC process can eliminate another operation later.
Michael sees another advantage as production grows: information no longer has to live entirely in one person's memory. Detailed digital models and drawings make it possible to reproduce parts consistently and manufacture replacement components later.
When production was smaller, a slight difference from one finished product to the next was easier to live with. That changes when customers need replacement parts or the same product must be built repeatedly. A replacement component needs to fit the product already in the field, which makes consistent drawings and digital models much more important.
Mark pointed out that CNC equipment can repeatedly produce parts with far tighter consistency than most manual processes. That is an advantage when the engineering is correct. But when the engineering is wrong, the same machine can rapidly produce an entire batch of perfectly repeatable bad parts.
Michael sees the same issue from the design side. A component can look right on a computer and still create a problem for the people assembling it. When that happens, the answer is not to insist the model is correct.
"We make changes," he explained. Fabricators and operators provide feedback about what is difficult to assemble or where additional locating details may help. That information goes back to engineering, where they update the model and drawings for the next production run.
Automation Changes Work, Not Eliminates It
Even inside the same company, people do not always define automation the same way. I describe the tube laser as highly automated because material can be loaded and processed through multiple operations with limited intervention.
Production supervisor William Walters draws a sharper distinction. From Will's perspective, the shop has extensive CNC equipment, but not true automation in the sense of an autonomous production line. Welding robots, for example, have been discussed but are not currently part of the operation.
That distinction is useful because smaller fabricators often modernize in stages. A CNC machine may automate a particular operation without creating an automated factory. The employee still has to understand the process.
Will points out that a machine can cut a component, but it doesn't necessarily know where that component belongs next. Operators still need to recognize parts, troubleshoot equipment, and recover when something goes wrong.
I view automation similarly. My goal is to use technology to remove repetitive or physically exhausting portions of a job while protecting skilled labor for work that requires judgment. That matters because real manufacturing rarely behaves as perfectly as the program expects.
A bend can be slightly off. Material can vary. A machine can stop because it detects a condition it cannot resolve. An experienced employee can assess the situation and decide what happens next.
New technology can also fail. One of our more expensive lessons was a roughly $30,000 software investment intended to improve production management and job tracking.
On paper, the system appeared capable of doing nearly everything the company wanted. The problem was implementation.
Migrating existing processes and information into the software required far more effort than expected, and the system ultimately proved more complicated for the company's operation than anticipated. After investing both money and time, the company backed away.
The lesson was not that manufacturing software is ineffective. It was that a sophisticated system is not automatically the right system. Modernization requires manufacturers to recognize when an investment is improving the operation and when they are continuing simply because they have already spent money on it. Sometimes the better decision is to stop, take the loss, and choose another direction.
The Next Bottleneck - Planning
When Will was asked what part of the production process he would improve next, he did not say another CNC machine. It was planning.
His daily concern is keeping enough components on hand so welders can keep working. That often means walking through bins and shelves to see what is getting low rather than waiting for someone to report the shortage.
Better equipment helps a shop produce more quickly, but that speed has to be coordinated. If engineering, cutting, bending, welding, inventory, and purchasing aren't in agreement on priorities, a faster machine hits the next bottleneck sooner.
Plans also change. A customer needs something immediately. A machine goes down. An outside repair walks through the door. Will's view is pragmatic: make the plan, get everyone moving in the same direction, and adapt when the plan inevitably changes.
That may be the most useful lesson from EWI's modernization. A small manufacturer does not become modern simply by buying newer machines. It becomes modern when equipment, digital information, processes, and experienced people begin working together.
Technology can cut faster, hold tighter tolerances, and repeat the same operation all day. People still decide what to make, how to make it, when the process needs to change, and whether the investment is actually improving the company.
Growth may force a manufacturer to modernize. It does not make human judgment obsolete. It makes good judgment more valuable.
