Key Benefits
- Hardened to HRC 50-60 to maintain sharp cutting edges during continuous plastics crushing operations
- Choice of tool steels like D2 and tungsten steel to match specific abrasive cutting conditions
- Production capacity of 100000 pcs per month supports regular plant consumption and replacement programs
- Custom coating options applied per drawing to extend working life and reduce material sticking
- Manufactured to fit specific CNC puncher and bender tooling holders without on site rework
- Wide selection of alloy steels available for distinct impact resistance or edge holding needs
Problems It Solves
- Premature edge chipping and wear on shredder knives processing abrasive plastic materials
- Difficulty sourcing non standard knife profiles because catalog tooling vendors do not customize geometry
- Machine downtime caused by unstable consumable blade wear and inconsistent tool steel hardness
- High tooling procurement costs when sourcing custom cutters from original machinery manufacturers
Who It Is For
- Plant maintenance managers sourcing high volume replacement knives for plastic shredder machinery
- Tooling procurement engineers ordering custom punches and dies for sheet metal fabrication equipment
- Machinery builders requiring custom knives manufactured to proprietary equipment drawings
- Industrial wear parts distributors stocking replacement tooling for shredding and metalworking machines
Application Scenarios
- Plastic recycling plants shredding rigid plastics and films requiring durable wear resistant blades
- Sheet metal fabrication shops running CNC punchers and needing custom profile replacement tooling
- Press brake bending operations requiring replacement or custom profile CNC bender tooling
- Industrial cutting stations processing tough synthetic materials where standard catalog knives wear fast
- Machinery builders constructing customized shredding equipment needing contract manufactured cutters
Technical Features
- Material range covers D2, 65Mn, 9CrSi, 6CrW2Si, Cr12MoV, SKD-11, W18Cr4V, and tungsten steel
- Standard working hardness controlled between HRC 50 and HRC 60 depending on the steel grade
- Machined and ground to customer dimensions for punchers, benders, and rotary shredders
- Custom surface coatings applied to enhance wear life and reduce sliding friction
- Monthly tooling production capacity rated at 100000 pcs per month
Materials
- D2 tool steel for high wear resistance and stable edges in plastics crushing operations
- Hard alloy tungsten steel for extreme abrasion resistance and long cutting intervals
- SKD-11 and Cr12MoV cold work die steels for tough cutting and shearing loads
- 6CrW2Si and 9CrSi alloy tool steels providing impact resistance under shock loading
- 65Mn spring steel and W18Cr4V high speed steel for specialized machinery tooling
- Set edge steel for specific machine knives and heavy duty cutting requirements
How It Is Made
- 1
Review of customer drawings, application demands, and cutting edge tolerances
- 2
Selection and preparation of specified tool steel or tungsten steel blanks
- 3
Precision machining and rough grinding to establish blade profile and mounting holes
- 4
Heat treatment and tempering to achieve the target hardness of HRC 50-60
- 5
Precision edge grinding and application of requested custom coatings
- 6
Final dimensional inspection and corrosion protective packaging prior to dispatch
Quality Control
- Hardness verification testing to confirm parts fall within HRC 50-60 specifications
- Dimensional inspection of mounting hole patterns and cutting edge geometry against drawing
- Edge finish evaluation to ensure clean cutting profiles free of burrs or microcracks
- Application of protective packaging to prevent cutting edge damage during international shipping
Customization Options
- Manufactured directly to customer drawings for shredder blades, punchers, and bender tooling
- Tool steel selection tailored to the specific raw material being cut or crushed
- Custom coating options applied to suit specific operating environments and wear conditions
- Mounting hole patterns, bevel angles, and dimensions made strictly to client specifications
Compared With the Alternatives
| Alternative | Honest trade off |
|---|---|
| Standard off the shelf catalogue blades | Custom blades match your machine holder geometry exactly but require drawing approval prior to manufacturing |
| Carbon steel utility knives | D2 and tungsten steel blades cost more initially but maintain cutting edges far longer in plastics crushing |
| Through hardened low alloy steel knives | HRC 50-60 tool steels offer superior edge retention but require careful material selection to prevent impact chipping |
Use Guide
- Provide technical drawings indicating blade geometry, mounting hole locations, and required tolerances
- Specify the material grade or state the material being processed so steel can be matched
- Confirm the required operating hardness within the HRC 50-60 range for your application
- Check knife seat alignment and torque mounting bolts evenly before operating newly installed blades
- Inspect cutting edges periodically to schedule rotation or replacement before excessive dulling occurs
