Inquiry
You load a roll of nonwoven fabric onto the unwind stand, typically PP or SMS, and machine pulls it through the ultrasonic welding station — that’s the core of what makes these covers hold together without stitching or glue, and it runs at a steady clip once you dial in the material thickness between 30 and 60 grams per square meter, which is pretty much the standard range for boot covers in cleanrooms or construction sites.
Most buyers go with the 440mm material width, and what that gives you is a finished boot cover that fits over a standard work boot or shoe — but if you change the mold, you can get different sizes, though we usually have the most common mold in stock and it takes about 20 days or so to custom-order a new one.
We’ve shipped these to hospitals, pharma cleanrooms, and automotive paint shops where they need to keep particles off the floor — it’s not suited for heavy-duty industiral overshoes with PVC soles, that’s a different machine entirely, but for disposable nonwoven covers it’s about as reliable as you’ll find in this price bracket.
The machine dimensions are 3300 by 1350 by 1950mm, and it weighs roughly 1000kg, so you’ll want a forklift or pallet jack to position it, and the aluminum alloy frame means it won’t rust even if your factory floor is humid — one thing buyers don’t always think about is that the ultrasonic horn needs periodic cleaning to avoid weld inconsistency, but the online training covers that.
Actually, the warranty is one year, and we include online support for setup and troubleshooting, but if you need on-site service that’s arranged seperately depending on your location — production capacity is usually around 30 to 40 pairs per minute, give or take, depending on the materail and operator speed.
For ordering, the MOQ is typically one unit, and lead time is about 30 days after the deposit clears, though we sometimes have a demo unit available if you’re in a hurry — just confirm stock before you wire payment, because customs clearance can vary by country and we ship from China with a full set of docs including CE and ISO certificates.
We don’t have a fixed MOQ on the machine itself — we can do single-unit orders. But if you need custom molds for different boot cover sizes, we typically require a small batch commitment of 50–100 pieces per mold to offset tooling costs.
Standard lead time is around 15–20 working days after payment confirmation. For custom molds or special nonwoven materials, add about 5–7 more days for production and testing.
Yes, both are included. We’ll provide the CE declaration of conformity and ISO9001 certificate with the shipment. If your customs requires notarized copies, we can arrange that too at no extra cost.
Definitely. The machine handles PP, SMS, and PP+PE nonwoven rolls. Material thickness should stay between 30 and 60 grams per square meter — anything thinner might tear, and thicker can jam the ultrasonic welder.
Size changes require swapping the mold set — it’s a quick-change system, but you’ll need a hex key and about 10 minutes. We include one standard mold with the machine; additional molds are ordered separately.
