If you’ve ever stood in a factory watching a main production line hum along, pumping out goods at a steady, impressive pace, you’ve probably noticed all the quiet, unassuming machines working right alongside it. Those are auxiliary machines—think conveyor belts, dryers, chillers, material feeders, and parts washers—that don’t make the final product, but without them, the main line would grind to a halt. For the last 12 years, I’ve run a small but reliable auxiliary machine supplier, working with food and beverage, plastic manufacturing, and pharmaceutical factories across the Midwest. Every day, I talk to plant managers and maintenance supervisors who are either overspending on underperforming auxiliary gear or dealing with breakdowns that cost them thousands in lost production. Most of the time, the root of the problem isn’t that they bought the wrong size machine—it’s that no one clearly outlined the input requirements those machines need to work well, before they signed the purchase order. Today, I want to break down the key input requirements of auxiliary machines, from the basics to the small, easy-to-overlook details that make all the difference. Auxiliary Machines
Let’s start with what I call the “foundational inputs” because without these, no auxiliary machine can operate at all. The first, and most obvious, is power. You’d be surprised how many plant managers assume a machine labeled for “110V single-phase” will work anywhere, or that they can use a 220V three-phase line for a machine that doesn’t have the right wiring. Last year, a plastic injection molder called me in a panic—they’d just installed a parts dryer from a competitor, and it kept tripping their circuit breaker every time it ran. When I showed up, I checked the machine’s data plate and realized it required a 208V three-phase power supply, but the plant had wired it to a standard 110V outlet. That small mismatch didn’t just waste their time and money on a wrong machine; it damaged the dryer’s heating element beyond repair, and they had to wait three days for a replacement part while their production line sat idle. Power inputs go beyond just voltage and phase count, too. You need to consider amperage draw—auxiliary machines like chillers or high-capacity conveyers can have sudden power spikes when they start up, and if your circuit doesn’t handle that, you’re looking at frequent outages. We always ask customers for their plant’s available amperage at the installation site, and whether they have a dedicated circuit for the auxiliary machine, because sharing a circuit with heavy equipment like stamping presses will cause constant voltage drops.
Next in foundational inputs is compressed air, a critical input for a lot of auxiliary machines, especially in packaging and automotive parts manufacturing. I’ve seen this trip up small food producers more than any other group. A craft cookie bakery I worked with a few years ago wanted to add an automatic wrapper to their production line, which required compressed air to seal the packaging and align the cookies. They had a small air compressor that worked just fine for inflating tires and powering hand tools, but it couldn’t keep up with the wrapper’s demand—every time the wrapper cycled, it dropped their air pressure from 90 PSI to 50 PSI, which caused the seals to fail and wrapped cookies to look unprofessional. The wrapper’s input requirement isn’t just “compressed air”—it needs to specify the pressure (measured in pounds per square inch, or PSI), the volume of air needed per minute (called CFM, or cubic feet per minute), and the air quality. If your compressed air has too much moisture or oil, it can damage pneumatic parts on auxiliary machines, leading to rust, clogs, and frequent repairs. We always ask customers to test their compressed air output at the point where they’ll connect the new machine, and if it falls short, we’ll help them size a small booster or secondary dryer to fix it, instead of selling them a wrapper that will never work as intended.
Once we get past power and air, we move into process-specific inputs—these are the details that make an auxiliary machine work with your unique product, not just any generic item. Take material handling auxiliary machines, like feeders, which are used to move raw materials (plastic pellets, grain, pharmaceutical powders) from storage tanks to the main production line. The biggest input requirement here is the physical properties of the material itself. A feeder that works great for plastic pellets will not work for fine pharmaceutical powder, because the powder will clump and jam the feeder’s mechanism. Last quarter, a small plastic extrusion plant bought a bulk feeder from a vendor that didn’t ask them about their material’s density—their material was a lightweight, porous resin, and the feeder was calibrated for dense PVC pellets, so it was moving too much resin at once, causing the extrusion line to have inconsistent thickness and waste 10% of their daily material. For material inputs, we need to know not just what the material is, but its particle size, density, flow rate, whether it’s hygroscopic (absorbs moisture) or not, and any abrasiveness—materials like recycled plastic are highly abrasive, so feeders need special, hardened parts to handle them, otherwise they’ll wear out in months instead of years.
Process inputs also include temperature and humidity, especially for auxiliary machines like dryers, chillers, and ovens that work with temperature-sensitive products. For example, in the plastic industry, many resins need to be dried before they’re molded—if they have too much moisture, the finished product will have bubbles and weak spots. A resin dryer’s input requirement isn’t just “it needs heat”—it needs to know the target moisture level for your specific resin (some require 0.02% moisture, others 0.1%), the ambient temperature of your factory floor, and the humidity in your production area. If you’re in a plant in the deep South where humidity hovers around 70% year-round, a dryer set for 170 degrees Fahrenheit will not work the same as it would in a dry, arid climate like Arizona. We once worked with a customer in Atlanta who bought a dryer from a company in California, and it could never get their resin dry enough because their ambient humidity was double what the California company’s equipment was calibrated for. That customer had to spend an extra $2,000 on a desiccant upgrade to fix the issue, and all because the original vendor didn’t ask about their local environmental inputs.
Another often-overlooked process input is space and layout constraints. Auxiliary machines don’t exist in a vacuum—they have to fit into your existing production setup, and connect to other machines, storage bins, or conveyor belts. I’ve had customers come to me wanting a high-capacity parts washer, but their only available space is a 3-foot gap between two production lines, while the washer needs 5 feet of clearance on all sides for loading, unloading, and maintenance. In another case, a pharmaceutical plant wanted a parts washer that would connect to their existing conveyor system, but the conveyor was a different width and height than the washer’s inlet, so they had to spend extra on custom adapters. Space inputs aren’t just about floor size, either—you need to consider access for maintenance: how easy is it to replace filters, clean out tanks, or access moving parts? We always ask customers for a detailed layout of their production area, including any overhead obstructions (like ceiling beams or overhead cranes) that might get in the way of a large machine, and where they’ll need to connect utilities like water or drainage.
Water inputs are another critical category, especially for auxiliary machines like chillers, parts washers, and cooling towers that use water for their operation. The requirement here goes beyond just “does the machine need water”—we need to know the water quality (hardness, pH level, presence of minerals or sediment), the flow rate needed, and whether the water will be recirculated or discharged. A chiller for a food processing plant, for example, can’t use hard water because the minerals will build up in the chiller’s tubes, reducing efficiency and leading to overheating. We recently worked with a small dairy farm that installed a milk cooling chiller, and within six months, the chiller’s tubes were clogged with calcium deposits, so it was using 30% more electricity to keep milk at the right temperature. The customer didn’t know that their well water (which they used for all operations) was extremely hard, and the chiller’s input requirement called for water softening. We added a small water softener unit, and now their chiller runs efficiently, with no more clogs. For machines that discharge water, like parts washers, you also need to consider your plant’s wastewater treatment capabilities—some parts washers use detergents that aren’t compliant with local environmental regulations, so we have to choose a machine that works with your existing treatment system, or help you adjust if needed.
Finally, there’s operational input requirements, which tie the machine to how your plant runs, not just the physical setup. This includes things like cycle time, which is how fast the machine needs to operate to match your main production line’s speed. If your main line runs 100 parts per minute, your auxiliary parts feeder can’t only move 80 parts per minute—it will become a bottleneck. We always ask customers for their line’s cycle time, so we can size auxiliary machines to match, or build in a small buffer to handle any slight fluctuations. Another operational input is maintenance capability: do you have in-house technicians who can work on the machine, or will you need training from our team? Some auxiliary machines require specialized skills—like programmable logic controllers (PLCs) for automated systems—so we have to make sure the customer’s team can either operate and maintain the machine, or that we can provide ongoing support. We also ask about shift patterns: if your plant runs 24/7, the auxiliary machine needs to be built for continuous operation, with heavy-duty parts, instead of the standard parts that work for single-shift operations.
After 12 years in this industry, I’ve learned that the best auxiliary machines aren’t the most expensive ones, or the ones with the shiniest labels—they’re the ones that are matched to your specific inputs. Every plant is different: a small craft bakery has very different needs than a large auto parts manufacturer, and a pharmaceutical plant has even stricter requirements than a textile plant. The worst mistake I see vendors make is selling a one-size-fits-all machine without asking about those critical input details, and the worst mistake plant managers make is not sharing those details, because they assume the vendor will know. That’s why, at our company, we don’t just take orders—we have a free, 30-minute consultation where we walk through every one of these input requirements, take notes on your plant, your product, your layout, and your operations, and then recommend machines that will work for you, not against you. If something doesn’t fit, we’ll tell you upfront, instead of selling you a machine that will cause you problems down the line.
