About the author<\/strong> \u2014 FOOTWORK LAB is a manufacturer of foot assessment equipment and custom orthotic insoles, based in Ruichang, Jiangxi Province, China. Founded in 2014, with its own production plant since 2018. Certified to European Union and ISO quality system standards. See the factory<\/a> or view certification<\/a>.<\/p>\n<\/div>\n

An insole machine for sale is usually bought at a distance, on a video and a conversation.<\/strong> The buyer cannot press material, cannot hear the hydraulics, cannot watch the temperature controller behave after an hour of running. That gap is where money is lost, and it can be closed with evidence rather than optimism.<\/p>\n

This article is for the buyer standing in front of a listing \u2014 new equipment from a supplier several time zones away, or a used press being sold because a lab closed or upgraded. Both situations share the same problem: the seller knows the machine and the buyer does not, and the asymmetry is being monetised.<\/p>\n

We do not sell presses. We run forming and molding in our own plant, which means we have bought equipment, lived with equipment and retired equipment, and we know which questions produce information rather than reassurance. That is the perspective this article offers.<\/p>\n

What a listing can and cannot tell you<\/h2>\n

A listing describes a machine the way a property listing describes a house: the photographs are chosen, the measurements are approximate and the problems are not mentioned. It is not dishonest, it is simply sales material, and it should be read as such.<\/p>\n

What a listing reliably tells you is the model, the approximate age, the footprint and the headline process. Those are enough to decide whether a machine belongs on your shortlist. They are not enough to decide whether it belongs in your building.<\/p>\n

What it hides is more useful. It hides the wear state of the heating elements, the condition of seals and hoses, the true cycle time on your material rather than the seller’s, the state of the tooling, and whether the controller has been replaced with something the original manufacturer no longer supports.<\/p>\n

There is also the question the listing never asks: whether the machine matches the product you intend to make. A well-maintained press that forms soft comfort blanks beautifully is not a bargain if your plan is semi-rigid shells. Fit beats condition every time, because condition can be repaired and fit cannot.<\/p>\n

There is a useful test of whether a listing is describing a machine or a fantasy. Ask the seller what the machine is worst at. Every machine is worse at something: a short draw, a slow changeover, a narrow material window, a controller that needs a laptop to reprogramme. A seller who names that limitation in one sentence is describing a real asset. A seller who cannot name one is either unfamiliar with the machine or hoping the buyer will not ask.<\/p>\n

Six pieces of evidence worth asking for<\/h2>\n

Evidence is different from assurance. Assurance is “it runs perfectly”; evidence is a recording you can stop, replay and compare against a checklist. Ask for six things, in this order, and watch how the answers arrive.<\/p>\n

The first is an uncut video of a complete run. Not a highlight clip: the full sequence from cold start, through warm-up, one forming cycle, a model change and a second cycle. Watch the clock in the frame. A seller who can supply this is a seller with nothing to hide about cycle rhythm.<\/p>\n

The second is a service history. Even a short list is informative: what was replaced, when, and why. A machine with a documented heating element replacement two years ago is a better purchase than one described as “never needed anything”, because the second claim usually means nothing was recorded.<\/p>\n

The third is the tooling inventory, itemised. Tooling is often worth as much as the press, and it is frequently excluded from the sale by accident rather than design. Ask for sizes, model numbers and condition, and ask who owns the drawings.<\/p>\n

The fourth is close-up photographs of wear parts: seals, hoses, platens, the mating faces of the tooling, the trimming blade if one is included. Wear is normal. What matters is whether the wear is uniform or localised, because localised wear usually means the machine has been run out of alignment.<\/p>\n

The fifth is a photograph of the controller screen with the current programme values visible. This tells you whether the machine is running a stored recipe or being driven manually, and manual operation is a warning sign about how the previous owner controlled quality.<\/p>\n

The sixth is the utility requirement in writing: electrical configuration, current draw, air supply if pneumatic, and any ventilation requirement. Buyers who skip this step discover the cost after the machine lands, when a new circuit or a compressor has to be added to a room that was already finished.<\/p>\n

Used against new, without romance<\/h2>\n

Used equipment is cheaper to buy and more expensive to own, in a ratio that varies with how well it was kept. New equipment is the reverse. The honest comparison is not the invoice, it is the total cost of the first two years.<\/p>\n

On the used side, the risks are known: spares may be discontinued, documentation may be missing, the manufacturer may no longer support the model, and the machine may have been adapted by an owner whose reasoning is not recorded. The last is the most dangerous, because adaptations usually work until they do not.<\/p>\n

On the new side, the risks are different: the machine may be built to a price for a market segment that is not yours, support may be thin after the first year, and delivery may arrive without the commissioning help that makes the first month workable.<\/p>\n

A used machine from a known plant, sold with tooling, documentation and a service history, is often the best value in the market. A used machine from an unknown seller, sold without tooling and with a video of it “working when disconnected”, is a project rather than a purchase. The difference between those two is entirely in the evidence.<\/p>\n

There is also a middle option that buyers forget: buying the machine new but buying the initial production from a factory. It keeps capital free until the demand is proven, and it gives the buyer a reference product to compare against when the machine finally arrives.<\/p>\n

Testing when you cannot be in the room<\/h2>\n

Distance does not prevent testing; it only changes the protocol. The essential move is to send your own material and your own model, rather than accepting output made from the seller’s. Material behaviour under heat is the single largest source of difference between two machines of the same model.<\/p>\n

Send three specifications, not one. Ask for them to be run in sequence, with a model change between the first and the second. Then ask for the finished pairs to be shipped to you, along with the process settings used for each. Comparing the three pairs against your own reference tells you more than any demonstration.<\/p>\n

Insist that the run is filmed, and that the film includes the settings screen before and after each cycle. A seller who runs your material and shows the numbers is giving you a process; a seller who sends a pair with no settings is giving you a sample, and a sample cannot be repeated.<\/p>\n

Finally, ask what happens when the material changes. Every real production environment changes material eventually: a new grade, a new thickness, a new supplier. A machine that can only be tuned by the person who installed it is a machine that will stop when that person stops answering.<\/p>\n

One further point about samples: they should be shipped with the pair inside the shoe you intend to use, or at least with the internal length recorded. A pair that matches on the bench and fills the shoe is not a match, and the discovery is much cheaper before the container is booked than after it arrives.<\/p>\n

The site cost nobody quotes<\/h2>\n

Machines fail to earn not because they are bad but because the room cannot support them. Electrical capacity, floor level, ventilation, access width and bench space are all decided before delivery and are all expensive to change afterwards.<\/p>\n

The access question is the one that embarrasses buyers. A machine that fits through the door on the drawing may not fit around the corner in the corridor, and a machine that has to be dismantled to enter a room is a machine that will be expensive to move again. Measure the route, not just the doorway.<\/p>\n

Ventilation matters more than buyers expect. Forming releases volatiles, and a room without extraction becomes unpleasant within an hour of production. Extraction is cheap during fit-out and expensive afterwards, when it has to be retrofitted around finished walls.<\/p>\n

Bench space is the quiet constraint. Forming is one step; trimming, bonding, cleaning and packing need surfaces, and those surfaces need to be where the operator already stands. A machine installed against a wall with no bench beside it produces a workflow where every pair is carried across the room twice.<\/p>\n

Payment, delivery and who carries the risk<\/h2>\n

The commercial terms of a machine purchase carry more risk than the technical specification, and they are usually negotiated last, when the buyer is tired. Three points deserve attention before signature.<\/p>\n

The first is what “installation” includes. Commissioning, operator training and a first production run are three different services, and suppliers bundle them differently. Ask what happens on day two, when the installer has left and the first real order is due.<\/p>\n

The second is the spares position. Ask for the spare parts list with part numbers, and ask which of those parts the supplier holds in stock. A machine supported by a supplier who stocks nothing is a machine that waits for a shipment every time something wears.<\/p>\n

The third is what happens if the machine does not perform on arrival. Written acceptance criteria \u2014 output compared against an agreed reference pair \u2014 are worth more than a warranty clause, because they define the disagreement before it exists.<\/p>\n

The same discipline applies to the price conversation. A quotation that arrives without the tooling list, the commissioning scope and the freight terms is not a price, it is a starting point for a negotiation that will end higher than it began. Ask for the complete landed cost in writing, including what is excluded, then compare that number with the alternatives rather than comparing the headline figures that appear in the first email.<\/p>\n

When a used machine is the wrong purchase<\/h2>\n

There are situations where the answer is simply no. If the machine’s manufacturer no longer exists and no equivalent controller is available, the machine is a consumable: it will run until something electronic fails, and then it will stop with no route back.<\/p>\n

If the tooling is worn beyond the point where pairs from the same model differ visibly, the purchase includes a tooling project that the buyer has not priced. Tooling is not a consumable in the way blades are; it is a capital item hiding inside a second-hand sale.<\/p>\n

If the machine has been adapted for a product you do not make, the adaptation has to be reversed, and reversing it requires the original drawings. Without drawings, the reversal is an experiment.<\/p>\n

And if the buyer’s plan depends on a specification the machine cannot hold, none of the above matters. Condition is repairable; fit is not. That is why the first question is always about the product, not the press.<\/p>\n

Buyers should also ask who will answer the telephone in year three. Equipment outlives enthusiasm, and the supplier relationship that felt close during the purchase is the one that determines whether a worn part arrives in a week or in a season. That is not a question a specification answers, and it is the question most likely to decide whether the machine is still running when the business has doubled.<\/p>\n

Frequently asked questions<\/h2>\n
\n

Do you sell insole machines?<\/h3>\n

No. Our scope is foot assessment systems and finished custom orthotic insoles. We run forming and molding in our own plant, so we can explain what a machine has to do, but we do not build or sell presses, ovens or trimming equipment.<\/p>\n

What is the single most useful thing to ask a distant seller?<\/h3>\n

For a full uncut video of a run using your material, with the settings screen visible before and after each cycle. It converts a claim into a process, and it is difficult to stage convincingly.<\/p>\n

Is a used machine from a closing lab a good buy?<\/h3>\n

Often, if the tooling, drawings and service history come with it. The value of a used press is mostly in what surrounds it. Without tooling and documentation, the buyer is purchasing a project with an unknown budget.<\/p>\n

How much floor space should I plan for?<\/h3>\n

More than the machine footprint. Plan for the machine, a bench on the operator’s working side, a clear approach for material and finished pairs, and space to open any guard or access panel. Buyers who plan only the footprint end up storing blanks on the floor.<\/p>\n

Can you produce a batch while we decide on equipment?<\/h3>\n

Yes. Insole production runs with a minimum order of two hundred pairs, mixable across models and sizes, and samples are dispatched within three days of specification approval. That gives a buyer a reference product to compare machine output against.<\/p>\n

What if the machine arrives and the output does not match the sample?<\/h3>\n

That is why written acceptance criteria matter. Agree a reference pair and a comparison method before shipment, so the conversation on arrival is about a defined standard rather than about impressions.<\/p>\n

Does the machine warranty cover wear parts?<\/h3>\n

For our own assessment systems, warranty runs twelve months on non-human damage with free replacement parts, supported by a dedicated WhatsApp group, direct access to our engineers and remote assistance where the site allows it. Press warranties vary by supplier and should be read line by line.<\/p>\n<\/div>\n

What we would do next<\/h2>\n

Before you commit to a listing, write the acceptance criteria: the model, the material, the specification and the comparison pair. Then ask the seller to meet them. If the machine is right, the criteria cost nothing. If it is wrong, they save the whole purchase. Buyers who would rather not buy a press at all can send specifications to our plant instead \u2014 the insole categories page<\/a> shows what we build, and the FAQ page<\/a> covers minimum order and sample timing.<\/p>\n
