Industrial Cutting Blades for the Plastic Processing Industry
The plastic manufacturing industry demands high-performance cutting solutions for film slitting, pipe cutting, pelletizing, and recycling applications. Our precision-engineered industrial blades deliver clean cuts, extended tool life, and maximum productivity, helping plastic processors optimize material yield and production efficiency. Below, we explore our specialized plastic cutting solutions in detail.
MAIDECAL : Cutting Blades for Plastic Processing
Our industrial-grade blades are optimized for thermoplastics, composites, and recycled materials, with key applications including:
- Plastic Pelletizing Hobs – For strand cutting in plastic granulation systems (PP, PE, PET).
- Plastic Film Slitters – High-speed slitting of BOPP, PVC, PET films (2μm–2mm thickness).
- Pipe & Profile Cutters – Smooth cross-cutting of PVC/PE pipes, window profiles (±0.1mm tolerance).
- Plastic Blanking Knives – Punching/die-cutting for bottles, containers & packaging.
- Plastic Shredder Blades – Heavy-duty crushing of post-industrial waste, drums, pallets.
- Extrusion Trim Knives – Edge trimming for sheet extrusion, blown film, and cast film lines.
These blades minimize melt adhesion, prevent delamination, and reduce energy consumption in high-throughput processing.

Technical Features & Performance Advantages
Our plastic cutting blades outperform competitors through:
- Ultra-Hard Materials – Tungsten carbide (TC), powder metallurgy steel (PM), or ceramic-coated edges for 3–5× longer life vs. standard HSS .
- Anti-Stick Coatings – PTFE/DLC coatings prevent polymer buildup on blades (critical for LDPE/PVC).
- Precision grinding & dynamic balancing to reduce vibration and extend blade life.
- Vibration-Reduced Designs – Dynamic-balanced rotors for smooth operation at 3,000+ RPM.
- Micro-Textured Edges – Laser-etched teeth patterns optimize chip evacuation in pelletizing.
- Corrosion Resistance – Nitrided/CVD-coated blades withstand acidic recycled plastics.
Results: 40% lower replacement costs, 30% energy savings, and ≤0.05mm cut precision.
Blade Materials & Engineering Specifications
Material Selection Guide
Material | Plastic Type | Advantages |
---|---|---|
Tungsten Carbide (TC) | Abrasive filled plastics (GF, CF, mineral-filled) | Extreme wear resistance, 10x HSS lifespan |
High-Speed Steel (HSS M2/M42) | General-purpose (PP, PE, PS) | Cost-effective, easy re-sharpening |
Powder Metallurgy Steel | Engineering resins (PC, PA, PEEK) | Balanced toughness/wear resistance |
Ceramic-Coated Blades | Adhesive films (PE, EVA, hot melts) | Non-stick, low friction |
Precision Manufacturing Process
- CNC 5-Axis Grinding – Ra 0.2µm surface finish for burr-free cuts.
- Cryogenic Treatment – -196°C deep cooling enhances hardness by HRC 3–5 points.
- Laser Hardening – Localized edge hardening (60–70 HRC) for impact zones.
- Dynamic Balancing – G2.5 grade (<1g imbalance) for high-speed spindles.
