FOAM APPLICATION INQUIRY
PU foam cutting band knives
Replacement band knife inquiries for PU foam cutting equipment used in furniture, bedding, cushioning, and foam conversion. Send the machine model, old blade label, or blade photos so the blade type and dimensions can be reviewed.
This page describes an inquiry route, not a confirmed machine compatibility list. Confirm whether the machine uses an endless band knife before ordering a replacement blade.
What to confirm for PU foam
- Tool type: confirm the machine uses an endless band knife, not an oscillating blade, reciprocating blade, or hot wire.
- Foam condition: state whether the material is flexible PU foam, rigid foam, memory foam, rebond foam, or a layered/loaded material.
- Blade record: provide full loop length, width, thickness, edge type, and tooth pitch or TPI if known.
- Cutting problem: describe rough edges, wandering, vibration, short blade life, breakage, or a weld-joint issue.
- Machine condition: mention guide, wheel, tension, or maintenance issues that may affect the result.
PU foam is not the same as EPS or every material described locally as foam. If the material or machine type is unclear, send photos and the machine nameplate rather than guessing.
Information to send
| Field | What to send |
|---|---|
| Full loop length (mm) | Full endless circumference and how it was measured |
| Blade width (mm) | Measurement points and a dimensioned drawing if available |
| Thickness (mm) | Old blade label or a dimensional record |
| Edge type | Plain edge, serrated/toothed, or unknown with a clear close-up |
| Tooth pitch / TPI | Value and unit if recorded; do not estimate from a photo |
| Machine brand / model | Nameplate photo or machine documentation |
| Material and condition | PU foam, memory foam, rebond foam, sponge, or other; state the actual material |
| Current problem | Wear, rough cut, breakage, tracking, weld issue, or other |
| Quantity / usage | Trial quantity and estimated monthly consumption |
Replacement review steps
- 01
Identify the machine
Send the machine brand, model, nameplate photo, or manual page. Confirm that the machine uses an endless band knife, not an oscillating or reciprocating blade.
- 02
Photograph the old blade
Send a full-loop photo, a close-up of the cutting edge, and any weld-joint or label detail. Keep the original label if it is still readable.
- 03
Record the dimensions
Provide full loop length, width, and thickness in millimetres. State whether the length is a full circumference or a folded measurement.
- 04
Describe the edge and material
State plain edge, serrated, or unknown, and record tooth pitch/TPI if known. Describe the actual foam material and the problem with the current blade.
- 05
Submit for specification review
Send the information through the quote form. Available dimensions, edge options, samples, packing, and commercial terms are confirmed in writing before an order.
PU foam band knife FAQ
Is this page for a foam cutting machine or a replacement blade?
This page is for replacement band knife inquiries used with PU foam cutting equipment. DEKOLY does not sell complete CNC foam cutting machines or hot-wire cutters on this page.
Does every PU foam cutting machine use an endless band knife?
No. Some machines use a band knife, while others use oscillating blades, reciprocating blades, or hot wire. Confirm the tool type before sending a band knife inquiry.
Can I order a PU foam band knife from photos only?
Photos help identify the blade, but dimensions and the machine model are also needed for review. Send the old blade label or a dimensioned record when available.
Is PU foam the same as EPS or xốp?
No. PU foam is a flexible polyurethane foam used in furniture, bedding, and cushioning. EPS and the Vietnamese term xốp can refer to different foam materials and may involve different cutting equipment.
Can DEKOLY confirm PU foam compatibility before a sample?
Compatibility is reviewed from the machine, blade dimensions, edge profile, material condition, and application. A trial or sample arrangement is confirmed separately when appropriate.
