Industries Served

Looking for Industrial Blades? Six Sectors, One Engineering Team

Each industry carries its own cutting mechanics —web tension, abrasive wear, hygiene grade, throughput. We tune blade geometry and steel grade to match. Industrial Knives has supplied converters, recyclers and OEMs across four continents since 1998 (ISO 9001:2015 certified since 2015), with a 98 % on-time delivery rate and a standard 5–6 weeks lead time.

Industries served by Industrial Knives —six sectors

Browse by sector

Pick the industry closest to your line

Each page documents substrate ranges, material grades, edge preparation and tolerance windows our engineering team has validated in production. If you do not see your cut listed, send us a drawing.

Printing & Packaging

Best for: slitting, sheeting and rewinding of paper, film, foil and laminate. Tight burr control protects printed surfaces and clean edges. Not for: ferrous metal coil slitting above 0.5 mm (use a Metalworking blade). Materials specified per ASTM A681 (D2) and JIS SKD11. Read more →

Paper & Tissue

Best for: long-life bed knives and top blades for tissue converting lines. Ideal for: 600–2,400 m/min tissue lines. Optimised cutting angles reduce dust and extend service intervals. Not suitable for hand-towel folding lines that require a creasing shoe retrofit. Read more →

Food Processing

Best for: slicing, dicing and portioning of bread, cheese, meat and vegetable lines. Stainless and tool-steel blades for washdown environments and food-contact compliance. Not for: cryogenic or frozen-block cutting (consult engineering first). Material traceability documented per ISO 9001:2015 §8.5. Read more →

Plastics Recycling

Best for: granulator and shredder rotor / stator knives cutting through contamination, glass fibre and reinforced polymers. D2 and M2 HSS options, with optional TiN or CrN coating to extend interval by 2—×. Not for: highly abrasive mineral-filled compounds above 40 % glass. Read more →

Converting

Best for: trim and score blades for pouch-making, label stock and adhesive tape lines. Repeatable edge profile across production shifts, with run-out controlled to ≤ 0.01 mm on Ø 250 mm blanks. Not suitable for very thick rigid sheet above 2 mm. Read more →

Metalworking

Best for: guillotine and swing-beam shears cutting mild steel, stainless and aluminium plate up to 12 mm. HRC 58–62 working hardness, ground and polished to ≤Ra 0.4 µm. Not for: hot-slab cutting (use a hot-shear grade with HRC 46–50). Read more →

Industry Comparison

Industrial Knives blade envelope, at a glance

Compared against typical job-shop and overseas-sourced equivalents. All values are production-validated, not theoretical. For a CAD-level quote, send a STEP, IGES or DWG file.

How we work

From drawing to dispatch, in six steps

A documented process that our engineering team has run on more than 10,000 production runs since 1998. Every step is auditable, every step has a backup plan.

Step 1: Submit a drawing or worn sample

Send your STEP, IGES, DWG or DXF file plus the operating envelope (substrate, throughput, web tension, hygiene grade). Our engineering team responds within one business day.

Step 2: DFM review and Cpk sign-off

We run a Design-for-Manufacturing review, propose a steel grade and edge geometry, and validate manufacturability with a Cpk ≥ 1.33 capability study on critical dimensions before tooling.

Step 3: Sample blade and field trial

A prototype is shipped for a 2–4 week field trial on your line. Yield, defect rate and edge life are logged against the agreed specification. We iterate up to two times before release.

Step 4: Production with 5–6 weeks lead time

Production orders are scheduled on a dedicated 5-axis grinding cell with a 5,000-blade monthly capacity and a backup machine on the same floor to protect your delivery date.

Step 5: MTC per EN 10204 3.1 and CMM inspection

Every shipment ships with a Mill Test Certificate per EN 10204 3.1, a HEXAGON Global S CMM dimensional report, and an AS9102-style FAIR package on request.

Step 6: Logistics, regrind and after-sales support

Standard Incoterms are FOB Ningbo, CIF or DDP. Worn blades can be returned for in-house regrind service —same steel, same geometry, lower cost per cutting hour.

Frequently asked

Cross-industry questions, answered

If your question is industry-specific, follow the link to that sector page for the relevant Q&A. All answers are reviewed by our engineering team each quarter.

Which industry blade should I start with if my line is not listed?

Pick the industry whose substrate and throughput are closest to your process, then send us a drawing. Our engineering team will re-classify the application and recommend the steel grade, edge geometry and tolerance window. Most cross-industry quotes are turned around within one business day.

What is the minimum order quantity (MOQ)?

MOQ is one blade for engineering samples. Production orders typically start at 20 units. For complex 4-edge indexable designs, the first production run is 50 units to amortise setup cost.

How long does a custom blade take from drawing to dispatch?

Standard geometries ship in 5–6 weeks. Custom builds against a new drawing typically ship in 8–12 weeks, including the DFM review and the field trial.

Do you regrind blades supplied by other manufacturers?

Yes. Send us a worn sample and we will measure the current edge geometry, regrind to OEM or Industrial Knives specification, and return a regrind report with edge-life expectations. We regrind blades from most major OEMs including Bosch, S&S, BSH and Herbert.

Which file formats can I send with my RFQ?

We accept STEP, IGES, DWG, DXF, SolidWorks and CATIA files. A 2D drawing with critical dimensions, hardness, surface finish and tolerance call-outs is sufficient for most catalog items.

How is the steel grade selected for a food-contact application?

For food-contact lines we default to 440C (DIN 1.4112) stainless with documented material traceability per ISO 9001:2015 §8.5, electropolished cutting edges, and a Mill Test Certificate per EN 10204 3.1 included in every shipment.

Proprietary framework

The 5-Factor Cut Validation Method

Every Industrial Knives blade is qualified against a proprietary 5-Factor framework before it leaves the floor: (1) substrate classification against ASTM A681 / DIN 1.2379 grade tables, (2) edge geometry on a 0.0019 mm HEXAGON Global S CMM, (3) hardness survey per Rockwell C with three-point mapping, (4) Cpk ≥ 1.33 capability study on the critical cut dimension, and (5) a documented 2–4 week field trial on the customer line. Lines that pass all five factors ship with a 98 % on-time delivery commitment and a 12-month edge-life guarantee.

What every quote includes

Written DFM review with steel grade and edge geometry rationale, returned within 1 business day.
Mill Test Certificate per EN 10204 3.1 with every production batch.
CMM dimensional report from a HEXAGON Global S coordinate measuring machine.
Hardness survey per Rockwell C with three-point mapping on every blade.
12-month edge-life guarantee on catalog geometries; Cpk ≥ 1.33 on custom critical dimensions.
