Why buy from the factory

Four things a trading company cannot offer.

The blade is made here

Machining, heat treatment and grinding are in our own plant. Nothing is subcontracted. If a batch goes wrong, we know which machine and which furnace it came off.

Quoted by the factory

The price comes from us, not from a trading desk adding a margin. Ask for it split by material, machining and heat treatment and we will send it that way.

One piece before the run

On a new drawing we make one piece first and send you the sizes with a photo. You approve it, then we run the batch. Traders cannot do this — they would have to order it first.

Wrong is ours to fix

If a piece comes out different from the drawing you confirmed, we make it again. No argument, no charge.

Buying replacement blades: what to send us

You do not need a drawing. If you are replacing a blade that is already running, send one of these and we will quote from it:

A worn sample — courier the old blade to the factory. It is the most accurate reference there is.
The machine brand and model, plus the blade dimensions if you have them.
A photo of the blade lying next to a ruler, with the fixing holes visible.
An OEM part number from the machine manual.

We reply within one working day. A test set can be ordered before any production quantity, and its cost is credited against your first production order.

How a blade is made here

Six steps. Nothing is subcontracted.

Drawing check

Send the drawing. We check the sizes and the steel with you and send back a confirmation before anything is cut.

Cutting

Material is cut to that confirmation. Cr12MoV, SKD-11, HSS, 440C and carbide are kept in stock.

Machining

Turning, milling and wire-EDM for the profile and the holes.

Heat treatment

Vacuum hardening and triple temper. Cryogenic soak if you need more wear life.

Grinding

Surface and CNC grinding for thickness, parallelism and edge angle.

Check and pack

Hardness on every piece, sizes checked, oiled, edge-protected, boxed.

Industries we serve

Blades are consumables. The right grade and geometry cut downtime as much as they cut material.

Packaging & Converting

Film, foil, label and tape slitting and rewinding lines. Blades changed by the week or the month.

Paper & Print

Paper mills, tissue converting, print finishing and three-knife trimming.

Corrugated & Carton

Slitting, cross-cutting, slotting, edge trimming and corner cutting on corrugated board.

Food Processing

Meat, seafood, bakery and vegetable lines. Stainless, wash-down safe.

Non-woven & Hygiene

Cutting and serrated knives for mask, diaper, sanitary pad and wet-wipe machines.

Wood & Panel

Chipping, flaking, finger jointing, edge banding and crushing.

Metal & Sheet

Shear blades, press-brake tooling, scrap and non-ferrous shearing.

Plastics & Recycling

Pelletizing knives, granulator and crusher blades.

Rubber & Tyre

Compound slitting, tread cutting, reclaimed rubber crushing.

Automotive & Battery

Electrode slitting, wiring, interior trim and separator cutting.

Blade Materials & Selection Guide

The grade decides how long the blade lasts and how it fails. Pick by failure mode, not by price.

Grade	Hardness	Wear resistance	Toughness	Best for	Our note
Cr12MoV	HRC 58–62	High	Medium	General slitting, paper, film, mixed packaging	Widely used, well understood grade. Good balance of cost and life.
SKD-11 (D2)	HRC 60–64	Very high	Medium-high	Abrasive film, board, high-speed converting	Longer life than Cr12MoV at higher cost. The default upgrade.
9CrSi	HRC 56–60	Medium-high	Medium	Paper, wood, economy tooling	Economical and forgiving. Common for large straight knives.
6CrW2Si	HRC 54–58	Medium	Very high	Chipper knives, scrap, impact-heavy cutting	Chosen when chipping is the failure mode, not wear.
HSS M2 / M42	HRC 62–66	Very high	Medium	High-speed lines, thin film, long production runs	M42 (cobalt) for heat resistance at very high line speeds.
440C Stainless	HRC 54–58	Medium-high	Medium	Food processing, wash-down, hygiene-critical	Rust-free. Required wherever blades see water and cleaning.
Solid Carbide	HRC 64–70	Extreme	Low-medium	Abrasive film, battery electrode, long-life demand	10–20× tool steel life, but brittle and not resharpened many times.
