Hey there,
I’m Jake, and if you’re reading this, chances are you work with (or own) a commodity making machine—you know, those workhorses that crank out everything from plastic cups to cereal boxes to those tiny metal fasteners we all take for granted. For the last 8 years, I’ve been on the ground as a supplier of these machines, talking to plant managers, shift leads, and maintenance guys who pull 12-hour days just to keep their lines running. The number one complaint I hear? Energy bills.
Like, not just “they’re a bit high”—but numbers so big that whole shifts get cut down to save a few kWh, or whole production lines are idling half the day because cranking them up and down feels like more trouble than it’s worth. I get it. Last quarter, a client in Ohio called me panicking because their natural gas bill jumped 28% in three months, and their machine’s electricity usage was driving half that spike. We fixed it, and in this post, I’m sharing exactly what we did—no jargon, no overcomplicated hacks, just real-world, field-tested moves that actually cut energy use without tanking production quality or breaking the bank. Commodity Making Machine
First, let’s get one thing straight: most commodity machines don’t waste energy because they’re “old.” They waste energy because people treat them like set-it-and-forget-it appliances. I’ve seen 5-year-old machines that run circles around 2-year-old ones because their operators adjusted tiny settings no one ever checks. Let’s start with the low-hanging fruit—stuff that takes 10 minutes to fix, no cost, and you’ll see savings before the end of the week.
Let’s talk about idle time. I can’t tell you how many clients leave their machines running 24/7 even when production is done. For example, a guy making disposable food containers would run his thermoformer overnight just to have it warm up fast at 7 a.m. Turned out, he could set a 45-minute pre-heat window right before the first shift starts, and the machine would drop its baseline energy use by 35% overnight. That’s not a small number. Another big one: unnecessary idling between batches. If you run a new batch every 2 hours, don’t leave the machine idling in “warm standby” the whole time—cool it down to a low hold temperature (most machines let you do this without risking damage) and only ramp up when the next batch is ready. I once worked with a plant manager who calculated his idling costs were $1,200 a week just from that setting. We knocked that down to $180. Game changer.
Next, the “vibe check” for motors. Commodity machines run on motors—tons of them. Conveyors, feeders, cutters, pumps—all that stuff. Most operators set motors to max speed because “it works fast enough” but that’s like driving your car on the highway in first gear. Super inefficient. For example, a stamping machine I supply has a variable frequency drive (VFD) on its main press motor. A client had it cranked to 60 Hz (max) when their production only needed 48 Hz. We dropped it to 50 Hz, and the motor’s energy use dropped 22%—and they didn’t notice a single difference in output or quality. Pro tip: If your machine has a VFD, check it at least once a month. I’ve seen machines where the VFD was set wrong because a new operator changed it while training and forgot to change it back. Also, listen to your motors. If they’re making a weird whine or grinding, that’s friction—friction means wasted energy. Tighten belts, lubricate bearings, replace worn parts. A friend who runs a metal stamping plant told me replacing a $10 bearing on his feeder motor cut that motor’s energy use by 14%. Tiny parts, huge payoff.
Now, the big one I always tell clients about: air leaks. If your machine uses compressed air (90% of commodity machines do), leaks are a silent energy drain. I once sent a tech to a plant that made plastic bottles, and he found 17 leaks in the compressed air lines—including one big enough to fit a pencil eraser. That leak alone was costing them $900 a month in wasted energy. We fixed it all, and their compressed air use dropped 18% total. How do you find leaks? Don’t use soapy water (that’s for old guys like me). Use a thermal camera. It’s $200 to rent from a hardware store, and you can spot leaks in 10 minutes. If you don’t want to rent, just walk the lines at night when the machine is quiet—you’ll hear the hissing. And fix them immediately. Even a tiny leak adds up fast.
Wait, also about compressed air pressure. Most machines are set to a pressure that’s way higher than they need. For example, a bottle blowing machine only needs 80 psi, but the plant had it set to 110 psi. Dropping it to 85 psi (to give a little buffer) cut their compressor’s energy use by 15%. That’s another easy win.
Now, for the folks who’ve tried all the small stuff and still need more savings. Upgrades. But I don’t mean replacing the whole machine (unless you want to). I mean targeted upgrades that pay for themselves in 18 months or less. Let’s start with LED lighting. If your machine uses old fluorescent lights, switch to LED. They use 75% less energy, last 25x longer, and don’t get hot (which is a big deal in plants that run hot from all the machines). A client that makes cardboard boxes swapped out 12 fluorescent fixtures on their printing machine, and their lighting energy bill dropped $210 a month. That’s $2,520 a year—super fast payback.
Then there’s high-efficiency motors. If you have old motors (pre-2010) that use standard efficiency, swapping them for NEMA Premium efficiency motors can cut energy use by 10-15%. I recently supplied a 5hp premium motor to a food packaging plant, and their motor-related energy use dropped 12% in the first month. The motor cost $800, and they saved $1,100 in the first 10 months—worth it.
Another upgrade: insulation. If your machine uses heat (like thermoformers, extruders, or drying ovens), the barrels and heater bands probably have old, worn insulation. Heat escaping means more energy to keep the machine at the right temp. We re-insulated a client’s extruder last year, and their heating energy use dropped 20%. No production downtime, just wrapped the insulated panels around the existing parts. Took 2 hours, cost $450, saved $1,800 a year. Duh.
Wait, also, automation. I know some people say automation is expensive, but modern sensors and small automation kits are not. For example, if your machine’s conveyor runs 24/7 even when there’s no product on it, a simple photo eye sensor can turn it off when there’s nothing to carry. A client that makes plastic lids added 4 small photo eyes to their conveyor line, and their conveyor energy use dropped 30%. That’s not a big automation project, that’s a $150 part and 20 minutes of installation.
Before I wrap up, let’s talk about the most overlooked thing: operator training. I can install all the VFDs, sensors, and insulation in the world, but if the new operator doesn’t know how to use them, it’s wasted. Last year, I trained a shift team at a metal stamping plant on how to adjust idle times, check motor settings, and spot air leaks. Within a month, their energy use dropped 10%—and they kept it there, because every new operator gets the same 20-minute refresh. It’s not a big class, it’s just “here’s why your machine’s bill is high, here’s two settings to change, here’s a sound to listen for.” That’s it.
Now, let’s be real. None of this is “build a zero-energy machine.” But it’s real, actionable stuff that I’ve seen work for hundreds of clients. The Ohio plant I mentioned at the start? They used a mix of adjusting idle times, fixing air leaks, and upgrading their LED lights. Their energy bill dropped 29% in 3 months. They didn’t have to buy a whole new machine, they didn’t shut down production for weeks, they just made small, consistent changes.
Commodity Making Machine If you’re reading this and thinking, “I have no idea where to start,” that’s fine. I know it’s overwhelming when you’re buried in production and paperwork. I work with all kinds of commodity making machine operators and plant managers—big and small. Whether you need a free 15-minute walkthrough of your machine’s energy settings, a quote for targeted upgrades, or help troubleshooting that weird energy spike, I’m here. No sales pitch, no fine print, just straight talk. If you’re ready to cut your energy bills and keep your machine running strong, hit me up for a chat.
