The 56 questions customers ask most

Before counting heads, find out what actually jams this step. If hiring is the problem — you can't recruit or retain — the value of the machine is removing “person” as a variable. If rework is the problem, the fix is process, not headcount. Typically one line runs with one operator inspecting and one handling load, but the real number depends on how many stations and which parts.

Short term yes, long term no. A good polisher does have the touch — but only those few people, and it changes when you change shift or they get tired. A machine won't match that person's best piece, but every piece sits on the same line. If you want to compare, send samples and we'll put roughness and gloss figures on the table instead of adjectives.

We build enclosed machines with internal filtration, the wash water is recirculated, and dust is collected in a box for disposal. But robot loading and dry polishing will still produce dust — that's honest. Dust is captured at the station, air volume sized to the number of stations, outlet connected to your existing extraction main. Inspectors check workplace concentration and the discharge point; we supply the duct drawing and airflow figures you submit. Wet polishing has less dust, but needs slurry circulation and drying, plus floor and water treatment.

First look at where it hurts: can't reach the grade, consumables eat too much, changeover too slow, or people won't stay. The first three can often be fixed — different belt spec, constant-pressure control, new fixtures — without a new machine. Replace only when cycle time and consistency are both stuck. Send me your current parameters and reject rate and I'll tell you if it's worth it.

Driven by station count, which parts you polish, and whether you need robots and extraction. Two quotes for “the same class” of machine can differ by 2x — the money is in stations and automation level, not the brand. Give me part dimensions, required surface and shift output, and I'll quote a range against a proposal.

Belts, cloth wheels, sisal wheels and polishing compound — the big part of long-term cost, well above electricity. How much depends on material and how much stock you remove. We build that number into the selection exercise; comparing machine price alone is misleading.

That's the right way. Send parts, or let us visit and watch how you polish today. Afterwards you get a roughness and gloss comparison plus a sample you can hold and touch — photos and video don't settle polishing.

Automating is turning hand skill into parameters. Tuning them takes some experience, but far less than finding a polisher who can hold a grade. Recipes are stored; recall one for a new part. We train your people.

It works, but three things catch up with you. First, it depends on feel: the same person differs morning and afternoon, and whether they are distracted that day changes the verdict — the standard isn't fixed. Second, it is slow: each unit waits a long time before anyone can call it. Third, nothing is recorded, so when a customer audits the plant and asks for test data you have nothing. The machine doesn't make the hand-check faster; it fixes heating, sensing and judgement as parameters and leaves a record for every flask.

Sampling and 100% testing are different jobs, and which one you need depends on what your customers demand. If you sample, define it properly — how many units, how long they rest, who signs off. If a customer requires 100%, or you have had a batch complaint, build it as an inline 100% station. Tell me your sampling ratio and who makes the call, and only then can I say whether it pays.

You and your customer set it: how long the flask rests, how much temperature drop counts as a failure — that is your call, we don't set standards for our customers. Our job is to make heating, sensing and judgement repeatable and the results exportable. Give me the standard and I write the logic against it.

Yes. Stored locally per flask or per batch, exportable, and it can feed your existing MES (interface built to your side — we don't push our own software). To trace one unit, the batch number gets you there. What an audit asks for isn't “we tested it”, it's “which batch, when, and who signed it off”.

It is not an off-the-shelf price. Three things drive it: how many stations (single or tandem), whether you need automatic loading, and whether it talks to MES. Give me your cup type and target output and I'll quote a range against a proposal — a number quoted blind is meaningless and you cannot compare it.

Yes, and I would recommend it. Send a batch of cups, good ones and rejects, but don't tell us which is which. We test blind, then hand you the verdicts and the process log and you score us. That is the only way to see whether the machine is actually right. If you are still unsure, we can arrange a trial at your plant.

Not hard. The interface is built for line operators, not engineers: load, unload, read the verdict. Training covers operation and daily upkeep together; most operators are running it within a shift.

Daily upkeep is cleaning and checking fixtures and sensors, which your own people can do. The main wear item is the heating element; we can teach a replacement in under an hour. If something fails, call us: one-year warranty on the machine, and after that we can attend on site in the Pearl River Delta and in Yongkang, Zhejiang. Exact warranty scope and response times are set in the contract.

The gain is one less transfer and one less clamping; the cost is that a single fault affects both halves. So the two halves must move and be tuned independently: if the welding head has a problem, rolling can still run empty; if you change the rolling die, the welding recipe library is untouched. If you want belt-and-braces, two separate machines also work — the price is an extra load/unload and one more positioning error.

A leaking longitudinal seam is usually lack of penetration or porosity. Three things matter in laser welding: gap, power and shielding gas. If the gap exceeds tolerance it won't penetrate, so butt accuracy after rolling must be stable — which is exactly why rolling and welding belong on one machine: one less transfer is one less chance to deform. Seam integrity is verified by pressure test or leak test, sampled per batch.

Rolling changeover means a different roll or die; welding means a different program. Same diameter, different height: ten minutes of programming. Different diameter: change the rolling module, half a day. How many sizes you run per month decides whether we build quick-change into the machine — and that has to be settled at proposal stage.

Absorption is lower than carbon steel, but it welds perfectly well — the parameters have to be calibrated to material and surface condition. Brushed, mirror and oiled parts all need different settings. We sample each part, store a parameter set as a recipe, and recall it on the next run. It isn't a knob an operator twiddles on the day.

Driven by cylinder diameter range, whether you need automatic loading, and whether rolling and welding are one machine or two. The price gap and the throughput difference both need to be laid out. Send diameter range, sheet thickness and target cycle time, and I'll quote a range against a proposal.

The laser source is maintenance-free. Protective lenses are inspected and replaced on a schedule, and cooling water is changed on the maker's interval. Those three decide whether a laser stays reliable long term — cheap, but somebody has to own them, so we write them into your check sheet.

Yes. Send sheet or semi-finished cylinders, we weld, then pressure test and section the seam to check penetration. Sectioning is the only honest way to judge a weld; photographs are not.

Same diameter, different height: ten minutes of programming. Different diameter: change the rolling module, half a day. How many diameters you intend to run is what decides whether we build quick-change in from the start.

Leaks are the thing that matters most in spout welding, and it's where we are least willing to be vague. A leak usually comes from two places: the fit-up gap between spout and body, or the weld path not matching. Laser welding is very sensitive to gap — too wide and it won't penetrate, too tight and it burns through. We clamp the spout into position with a locating fixture first, then weld with parameters calibrated to that part, not to a welder's feel.

A laser seam is narrow with no raised bead, so normally it needs no grinding. If the seam lands on a visible face and the part must be mirror or brushed finish, it still gets one polishing pass. That's still less work than TIG — the bead you get at a kettle rim with TIG almost always has to be ground off, and that's one more process and one more person.

Yes, but the tooling is completely different. A single-wall kettle is thin (0.4–0.6 mm), so power comes down and speed goes up. A double-wall pot welds the joint between inner and outer shells, and the vacuum layer must not be breached. One fixture cannot do both. Send the shapes and wall thicknesses and I'll tell you whether it should be two machines.

Yes, provided cycle time and load/unload method agree. Either a standalone station with manual loading, or inline in your conveyor so parts flow automatically. Inline needs communication and cycle synchronisation (stop when upstream is empty or downstream is full), which is line integration work and gets laid out on the drawing.

Driven by spout type, whether you need automatic loading, and whether it goes inline. A single station with manual loading and an inline unit are two different budgets. Send spout type, wall thickness and required cycle time, and I'll quote a range against a proposal.

The laser source itself is maintenance-free, but protective lenses are inspected and replaced on a schedule — spatter contaminates them and a dirty lens costs you power. It's a normal consumable, not expensive, but it has to be changed on time rather than after you notice the weld doesn't penetrate.

Sampling is the right starting point. Send spouts and bodies, a dozen sets each. We weld them and show you the seam appearance plus a pressure or leak test, so you can judge whether the seam is acceptable.

If spout position or angle changes, you change the tooling and re-teach the path. Different batches of the same spout only need parameter tweaks. How many spout types you run and how often you switch is what decides whether we build quick-change tooling.

This is the right question to ask. Human fastening leaves no record; a machine can stop a miss. Torque curve, drive depth and seating signal must all agree before a screw counts as good; if they don't, it alarms and stops instead of quietly moving on. So the machine isn't selling speed — it's selling proof that nothing was missed.

Yes, but the difficulty with small screws isn't driving, it's feeding and holding. Below M1.5, blow feeding tends to flip the screw, so vacuum pick is usual; the nozzle bore has to match the head type. One cost to plan for: on small screws the driver bit is a consumable, and on two shifts a bit every two or three days is normal. That's an operating cost, not a fault.

Within a family, changing model (small coordinate shift) is ten minutes of programming. Changing to a completely different product means new fixture and nozzle, half a day to a day. That's why I ask how often you change lines per month: frequent changeover means quick-release fixtures and multiple stored programs; infrequent changeover means a fixed fixture, which is both cheaper and more rigid.

It depends on how many screws per part and how many seconds you allow. Few screws at fixed spacing: multi-spindle simultaneous driving is fastest. Many screws at known coordinates: an XY table driving point by point is cheaper. Scattered screws on several faces: a robot. Driving too many at once can bow thin parts; driving too few won't make cycle time. Send the screw layout and I'll lay out the stations.

Three numbers decide it: screws per part, number of stations, and whether you want fastening verification and data. Multi-spindle, XY and robot solutions differ a lot. Give me the screw spec and the layout and I'll quote a range against a proposal, not a bare machine price.

Driver bits, nozzles and feed tubes are normal wear parts, stocked to your spec so you don't wait. Bits are cheap but changed often, so I'll calculate a year's usage against your shift pattern — better that than a line stopped over a one-dollar bit.

Yes. Send parts and screws, 50 of each or more. You get back a fastening record: torque curves, pass rate, jam count. Those three numbers are worth more than any spec sheet.

On an XY machine, changing the program takes ten minutes; on a multi-spindle machine a model change is mostly a fixture change. We train until your own people can change programs and fixtures, not until you depend on remote support.

A loose rivet (under-set) is insufficient stroke or insufficient pressure — not luck. We fix the stroke first and use pressure only for fine adjustment, and the pair is locked in a recipe. Change the rivet specification and we re-trial; we never carry the previous setting over. In production we check every 30 pieces for head cracking, single-sided set and die marking, and pull-test on a sample.

It can, which is why the lower die is contoured to the part. The support face is machined to the part profile, radiused and polished, and anything touching a visible face gets polyurethane or a nylon die. Thin panels are set with low pressure in several steps rather than one full stroke. Show me the part and the die gets made to it.

Yes, but pull riveting and press riveting are not the same machine. A pull rivet forms by breaking its mandrel, so the tooling is a nose assembly or a pull module. Press riveting forms by squeezing between punch and die. Force and stroke differ completely, and one machine does one of them. If you use blind rivets, I quote a pull-riveting solution — I won't try to convert a press.

It depends on station count, number of rivets and whether the part is flipped. One station sets one rivet per stroke; with three, four or five stations they run in sequence, so cycle time is station count divided by set time. Tell me rivets per part and the cycle you need and I'll work out the stations — a bare "pieces per minute" figure is meaningless because it changes with the next product.

Driven by station count, rivet specification and whether feeding is automatic. The difference between three and five stations, and between manual and bowl feeding, sits in the stations and the feed mechanism. Send rivet spec, rivets per part and target cycle, and I'll quote a range against a proposal.

The set head is a wear part, and once it wears the set is out of spec — so the head is checked for flatness at the start of every shift and replaced when it chips. Replacing a set head is neither expensive nor complicated, but the tooling is made to your rivet head shape, so keep a spare set on the shelf.

Yes. Send parts and rivets, a batch of each. You get back photographs of the set, pull-test data, and a note on die marking — which matters especially for visible parts.

Simpler than polishing. The operator loads, unloads and watches the set head. The difficult part is first-off setting, and we do that and store it as a recipe, so your people just recall it for the next part.

Not just equipment. How forming, die cutting, stacking, carding and inspection connect; where the line sits; how the cycle is balanced; where people stand to take parts off — all of that is drawn. We install, commission and train on site, and we only leave once it produces steadily.

Work out changeover cost first. A line suits one or a few specifications running for a long stretch; if you change the mould every three days, changeover eats the efficiency a line is supposed to give you. In our experience the order volume must at least sustain a mould change once a week — if it can't, start with a single machine or a semi-automatic station rather than forcing a full line.

It depends on station count and product size. A configuration we have built runs 18 stations on a blister 190 × 110 × 93 mm at roughly 700 pieces per hour. Give me your output target and I'll work back through station count and cycle time — the same line running a different product or size will produce a different number, so one figure on its own means nothing.

Against what your customer demands. Appearance (whitening, flow marks, uneven wall, offset), dimensions and seal strength have to be agreed first — the quality standard is the precondition for planning the line. Until the standard is settled, station count and cycle time can't be pinned down. The inspection method follows the cost of a defect: cheap to scrap, sample by hand; expensive, add vision or inline inspection.

Blister packaging lines for toys, household goods, hardware and food, including deliveries to overseas factories. Specific customers and site conditions don't belong on a public page — we can talk in person, or I can send you line video, which beats reading text.

Driven by station count, cycle time and whether you need inspection and cartoning; the spread is wide — a semi-automatic line and a fully automatic line are different orders of magnitude. Send product size, target output and your current process and I'll come back with a concept and a price range before we get into detail.

Yes. We have video of lines in production, and sites we can take you to (with notice, out of courtesy to the customer). Blister lines only show half of themselves in video — it's better to watch one running.

Daily checks and cleaning are done by your operators; we supply the check sheet. Mould changes, air circuit and temperature control faults we support remotely or on site. A line has many parts, so maintenance responsibilities get itemised at acceptance — one by one, in writing.
