DEKOLY / FOAM CUTTING

Foam Cutting Band Knives

Replacement band knife inquiries for CNC contour cutting machines, foam splitting equipment, and other foam cutting machines. Send the machine model, old blade label, or clear blade photos. DEKOLY reviews the blade specification before quoting.

This page is for replacement band knives, not complete cutting machines or hot-wire equipment. Material and machine names are inquiry inputs, not a confirmed compatibility list.

Full loop length ≠ folded length Length · Width · Thickness · Pitch / Edge
Specification diagram, not to scale; not a product photograph.

Choose the inquiry path

Start from the existing blade. If the edge type is not clear, use the general inquiry and send photos; do not guess between serrated and plain edge.

What to send for review

You do not need every item to start. The machine nameplate, old blade label, or clear photos are enough to open a review. Final specifications are confirmed in writing.

Send the information you have
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

Plain edge vs serrated band knife

The edge type must match the existing blade and cutting requirement. Appearance alone does not confirm interchangeability; send a close-up and the original label when available.

Edge type What it means What to send Inquiry path
Plain edge / toothless A continuous cutting edge without a toothed profile. The exact edge geometry must be confirmed from the old blade. Full blade photo, edge close-up, label, and dimensions Review path →
Serrated / toothed A blade with a toothed cutting profile. Tooth shape, pitch, and set direction must match the existing machine and cut. Close-up of several teeth, pitch/TPI record, label, and dimensions Review path →
Unknown / not sure The existing blade or label is missing, damaged, or cannot be identified from the photo. Machine nameplate, old blade photos from several angles, and any dimensional record Review path →

Replacement band knife workflow

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

Foam material and machine inputs

Describe the actual material and machine. These categories help route the inquiry; they do not confirm that a specific blade is suitable.

  • PU foam
  • HR foam
  • Memory foam
  • Rebond foam
  • Sponge
  • Other foam or cellular material

CNC contour cutting machine

Confirm the machine uses an endless band knife. Do not assume that every CNC foam cutter uses the same blade type.

Foam splitting machine

Provide the existing blade dimensions and edge type. Splitting and contour cutting can place different demands on the blade.

Other band knife equipment

Send the machine documentation and old blade photos so the blade type can be reviewed.

Foam band knife FAQ

Does DEKOLY sell foam cutting machines?

No. This page is for replacement band knife inquiries. DEKOLY supplies industrial band saw blades and foam cutting band knives, not complete CNC foam cutting machines or hot-wire equipment.

Can I request a foam band knife without full dimensions?

Yes. Start with the machine nameplate, machine brand and model, old blade label, or clear photos of the old blade. A full loop length is helpful, but an incomplete specification can still be submitted for review.

How do I know whether I need a serrated or plain-edge band knife?

Compare the old blade edge, the original label, and the cutting requirement. A visual resemblance does not confirm interchangeability. Send a close-up of the edge and several teeth so the profile can be reviewed before a quote.

How is band knife loop length measured?

Loop length means the full circumference of the welded endless blade, not a folded length. Use the old blade label or machine documentation when available, or follow the measurement guide and state the units clearly.

Do you supply customers in Vietnam and Indonesia?

DEKOLY is based in China and reviews export inquiries from Southeast Asia. Shipping terms, product documents, destination requirements, samples, and commercial conditions are confirmed for each inquiry in writing. DEKOLY does not claim a local warehouse or office in Vietnam or Indonesia.

Are PU foam, memory foam, and rebond foam confirmed as compatible materials?

They are material categories used to describe an inquiry, not a confirmed compatibility list. Suitability depends on the machine, edge profile, blade dimensions, material condition, and trial result. Each request is reviewed before a specification is confirmed.

Send the old blade, machine model, or label

A full specification is not required to start. DEKOLY reviews the information and confirms the next step before a quote.
