ECON21 Shredder / Granulator Knife — 40 x 30 x 2.8 x 35D, M2 (1.3343 DMo5) by MetavCUT

The ECON21 is a precision replacement knife for ECON recycling and granulating machines, engineered to deliver consistent cutting performance in shredders and granulators.

• M2 (1.3343 DMo5) high-speed tool steel
• Precisely ground 40×30×2.8×35D profile
• Compatible with ECON shredders and granulators
• Optimised for low dust and uniform granulate

Consistent cuts that reduce downstream rejects

The replacement blade is designed for repeatable, clean cuts which translate into uniform pellet size and fewer rejects. Using a blade made from M2 (1.3343 DMo5) ensures a balance between hardness and toughness, so the knife maintains its profile under continuous load. The precise geometry of the knife reduces the formation of fines and dust, which helps to protect screens and sieves and lowers the need for secondary processing. This yields measurable productivity gains and a steadier product quality for industrial recycling lines.

Material selection that extends wear life

Manufactured from M2 tool steel, the blade combines high wear resistance with good edge stability. In practical terms, this means longer intervals between regrinds and reduced consumable turnover. The steel grade is chosen for its ability to hold a sharp edge at the operating temperatures typical in shredding and granulation, while resisting chipping on mixed plastic streams. For operations that value predictable maintenance cycles, the material choice contributes directly to lower total cost of ownership and fewer unscheduled stops.

Designed for process stability and cleaner production

Fitted in shredders, granulators or pelletisers, the knife supports stable throughput and cleaner output. The ground cutting edge minimises smearing and ensures that extruded strands or flakes are separated evenly, producing a consistent granulate that feeds downstream processes more effectively. Improved chip formation and reduced dust generation also support safer and cleaner plant conditions, which can reduce filter loading and maintenance on extraction systems.

Simple replacement, clear compatibility and commercial reliability

The blade is manufactured to match the 40 x 30 x 2.8 x 35D profile used in ECON equipment, which simplifies inventory management and reduces fitment errors during maintenance. As a dedicated wear part, the knife is precision ground to ensure a straightforward swap with OEM geometries. The combination of reliable dimensions and high-grade steel delivers a pragmatic upgrade path for plants seeking cost-effective sustainability in daily operation.

FAQ

What machines is this knife compatible with? The knife is compatible with ECON recycling, shredding and granulating machines; the ECON21 blade matches the specified profile for direct replacement.

What material is the blade made from and why does it matter? Manufactured from M2 (1.3343 DMo5) tool steel, the blade offers a combination of hardness and toughness that extends wear life and maintains edge stability under cutting loads.

How does this knife affect granulate quality? A precisely ground edge produces more uniform pellets and reduces fines and dust, which improves downstream processing and reduces sorting or sieving effort.

Can the blade be resharpened or is it a single-use part? The knife is a replaceable wear part; resharpening is possible depending on wear pattern, but the M2 material is selected to maximise time between regrinds.

Does the blade suit mixed-plastic streams? Yes, the blade’s geometry and material make it appropriate for mixed plastic waste streams commonly processed in industrial recycling plants.
