Forty years in tool and die means they've seen every version of the problem. Progressive dies. Transfer dies. Draw dies. Pierce, blank, form and trim. Built them, maintained them, modified them for customers who keep coming back.

That kind of experience doesn't show up on a spec sheet. It shows up when a die has a failure mode nobody anticipated and the person looking at it has seen it before.

Intangible investment is growing faster than traditional investment in plants and machinery—and that shift matters for manufacturers.

Because having more production capacity doesn’t help if your product pipeline has stopped moving.

They’ll be the ones that know 𝐰𝐡𝐚𝐭 𝐭𝐨 𝐦𝐚𝐤𝐞 𝐧𝐞𝐱𝐭.

If your engineering team is buried in today’s projects while tomorrow’s product ideas keep getting pushed back, it may be time to rethink where your capacity is going.

Nine days from now, the best conversations in Missouri manufacturing happen over a drink.

𝐌𝐚𝐧𝐮𝐟𝐚𝐜𝐭𝐮𝐫𝐢𝐧𝐠 𝐨𝐧 𝐭𝐡𝐞 𝐑𝐨𝐜𝐤𝐬 𝐢𝐬 𝐛𝐚𝐜𝐤 — 𝐓𝐡𝐮𝐫𝐬𝐝𝐚𝐲, 𝐒𝐞𝐩𝐭𝐞𝐦𝐛𝐞𝐫 𝟏𝟎.

No sales pitch. No panel discussion. No name tags with your job title in 6-point font. Just manufacturers, engineers, and the people who actually make things, in one room, talking about the work.

Every time we host this, the same thing happens. Somebody mentions a problem they've been fighting for six months, and somebody across the table says “we solved that two years ago, let me tell you what we did.” That's the whole point.

𝐓𝐡𝐮𝐫𝐬𝐝𝐚𝐲, 𝐒𝐞𝐩𝐭𝐞𝐦𝐛𝐞𝐫 𝟏𝟎. 𝐒𝐚𝐯𝐞 𝐭𝐡𝐞 𝐝𝐚𝐭𝐞!

𝐖𝐡𝐚𝐭 𝐢𝐟 𝐭𝐡𝐞 𝐰𝐚𝐲 𝐲𝐨𝐮’𝐯𝐞 𝐚𝐥𝐰𝐚𝐲𝐬 𝐝𝐨𝐧𝐞 𝐢𝐭… 𝐢𝐬𝐧’𝐭 𝐭𝐡𝐞 𝐛𝐞𝐬𝐭 𝐰𝐚𝐲?

The biggest manufacturing improvements don’t always start with expensive equipment or complex technology.

They start with someone asking: “Why are we doing it this way?”

That question can uncover wasted time, unnecessary steps, quality issues, excessive costs, or an opportunity to build something better.

Innovation starts when someone is willing to challenge “𝐛𝐞𝐜𝐚𝐮𝐬𝐞 𝐭𝐡𝐚𝐭’𝐬 𝐡𝐨𝐰 𝐰𝐞’𝐯𝐞 𝐚𝐥𝐰𝐚𝐲𝐬 𝐝𝐨𝐧𝐞 𝐢𝐭.”

🔥 Your turn: What’s ONE thing in manufacturing you think could be done better?

Drop it in the comments. Let’s challenge the status quo.

Nobody ever got fired for adding one more supplier. 𝐁𝐮𝐭 𝐞𝐯𝐞𝐫𝐲 𝐬𝐮𝐩𝐩𝐥𝐢𝐞𝐫 𝐲𝐨𝐮 𝐚𝐝𝐝 𝐢𝐬 𝐚𝐧𝐨𝐭𝐡𝐞𝐫 𝐡𝐚𝐧𝐝𝐨𝐟𝐟 — 𝐚𝐧𝐝 𝐡𝐚𝐧𝐝𝐨𝐟𝐟𝐬 𝐚𝐫𝐞 𝐰𝐡𝐞𝐫𝐞 𝐭𝐡𝐢𝐧𝐠𝐬 𝐛𝐫𝐞𝐚𝐤.

Think about a single assembly in your product. Cut at one shop. Machined at a second. Heat treated at a third. Coated at a fourth. Each one is competent. Each one hits their piece of it.

And yet the assembly shows up wrong.

The fabricator worked from Rev C. The machinist got Rev D. The coater masked the wrong holes because nobody told them the spec changed. Not one of those vendors failed at their job — the failure lives in the seams between them, where nobody owns the outcome.

The more vendors touching a part, the more seams. The more seams, the more of your team's time gets burned playing traffic cop: chasing revisions, reconciling dates, translating between shops that have never spoken to each other.

That coordination doesn't show up on any quote. You pay for it anyway — in freight between shops, in schedule padding, in the parts that come back wrong.

There are two fixes. Tighter documentation, so every vendor is working from the same, current truth. Or fewer seams altogether.

𝐖𝐞 𝐡𝐞𝐥𝐩 𝐰𝐢𝐭𝐡 𝐛𝐨𝐭𝐡 — 𝐞𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐢𝐧𝐠-𝐠𝐫𝐚𝐝𝐞 𝐭𝐞𝐜𝐡𝐧𝐢𝐜𝐚𝐥 𝐩𝐚𝐜𝐤𝐚𝐠𝐞𝐬 𝐨𝐧 𝐨𝐧𝐞 𝐬𝐢𝐝𝐞, 𝐚𝐧𝐝 𝐚 𝐟𝐚𝐦𝐢𝐥𝐲 𝐨𝐟 𝐟𝐢𝐯𝐞 𝐦𝐚𝐧𝐮𝐟𝐚𝐜𝐭𝐮𝐫𝐢𝐧𝐠 𝐜𝐨𝐦𝐩𝐚𝐧𝐢𝐞𝐬 𝐮𝐧𝐝𝐞𝐫 𝐨𝐧𝐞 𝐫𝐨𝐨𝐟 𝐨𝐧 𝐭𝐡𝐞 𝐨𝐭𝐡𝐞𝐫.

𝐎𝐧𝐞 𝐩𝐚𝐫𝐭. 𝐅𝐨𝐮𝐫 𝐛𝐮𝐢𝐥𝐝𝐢𝐧𝐠𝐬. 𝐙𝐞𝐫𝐨 𝐩𝐮𝐫𝐜𝐡𝐚𝐬𝐞 𝐨𝐫𝐝𝐞𝐫𝐬 𝐛𝐞𝐭𝐰𝐞𝐞𝐧 𝐭𝐡𝐞𝐦.

Here's what a part can look like moving through the 𝐁𝐢𝐠 𝐑𝐨𝐜𝐤𝐬 𝐌𝐚𝐧𝐮𝐟𝐚𝐜𝐭𝐮𝐫𝐢𝐧𝐠 𝐟𝐚𝐦𝐢𝐥𝐲:

The engineering starts at Big Rocks Engineering — the model, the drawings, the technical package. The blank gets cut and formed at Mack Hils Metal Fabrication. Precision features get machined at CED Precision Machining. The tooling behind the stamping came out of Roberts Tool & Die Company. And the finished part gets powder coated, kitted, and shipped from Total Powder Coat & Finish, LLC..

Now here's the part that matters to you: when that handoff happens between our companies, nothing gets lost. The engineer who made the drawing can walk the floor where the part is made. A tolerance question gets answered with a phone call, not a two-week email chain between four vendors who've never met.

Compare that to managing the same part across four unrelated suppliers. Every handoff is a gap. Every gap is a place where dimensions drift, schedules slip, and accountability disappears into the space between companies.

We didn't build the family this way by accident. We built it because the handoffs are where manufacturing goes wrong — so we brought the handoffs in-house.

If you're managing a part that touches three or four different vendors today, 𝐟𝐢𝐥𝐥 𝐨𝐮𝐭 𝐭𝐡𝐞 𝐜𝐨𝐧𝐭𝐚𝐜𝐭 𝐟𝐨𝐫𝐦 𝐨𝐧 𝐨𝐮𝐫 𝐰𝐞𝐛𝐬𝐢𝐭𝐞. Worst case, you'll learn what a consolidated quote looks like.

Every successful manufacturing project begins with a solid engineering foundation, from accurate designs and specifications to proper dimensions, materials and tolerances.

When those details are correct from the start, manufacturers can produce parts more efficiently, consistently and with fewer costly mistakes.

Most automation projects I've seen fail don't fail because the robot didn't work. They fail because nobody spent enough time on the diagnosis before the purchase order went out.

Four places it goes wrong, and I've watched all four up close:

You automate the wrong machine. In a job shop the constraint moves — it's the mill this week and the inspection table next week — and utilization reports won't show you a human bottleneck at all.

You roll it out quietly. Operators aren't the only ones who resist. Plant managers do too, when it feels like a referendum on how they've run the shop.

You guard the cell but skip the paperwork. The injuries cluster around setup and changeover, not normal production.

You divide equipment cost by wage rate and call that payback. That number never survives the first question from your CFO.

None of this is an argument against automating. It's an argument for doing the work before you sign.
