Product Overview
Bottle‑cap slitting blade is a dedicated cutting part for plastic recycling dismantling equipment. It splits various plastic and composite bottle‑caps. Edge quality ensures flat cuts and stable‑efficient operation of recycling pre‑treatment lines.
Profile & Structural Design
Multi‑bevel pointed‑tip with compound cutting edges. Progressive‑cut‑in buffers shear impact and reduces chipping. Flat substrate and reference surface fit stationary seats and rotary holders. Multi‑facet tip works for composite caps with ribs and gaskets, resists deformation and delivers smooth cuts.
Material Selection
Two steel grades available: 42CrMo, Cr12MoV. 42CrMo offers good rigidity and impact‑resistance for lines with impurities and complex conditions. Cr12MoV provides high wear‑resistance and longer‑life edge for high‑volume continuous production.
Manufacturing & Process Features
Processed by forging, rough grinding and precision grinding. Custom heat‑treatment balances rigidity, wear‑resistance and toughness. High‑finish ground edge reduces hot‑melting plastic sticking. Stress‑relief treatment minimizes deformation risk under long‑time high‑speed operation.
Main Application Scenarios
For plastic‑recycling pre‑treatment. Processes PP, PE caps and composite caps with rubber gaskets for longitudinal splitting and circumferential slitting. Cuts inner ribs and bosses, widely used in cap dismantling and plastic‑sorting pre‑processing lines.
Core Product Advantages
Multi‑bevel progressive‑cutting edge saves cutting force and reduces plastic debris. High rigidity resists heavy‑load deformation. Stress‑relieved structure keeps dimension stable in long‑hour high‑speed running, lowers defect rate for various cap materials.
Specification & Customization Scope
Blade thickness, tip angle and effective edge length are adjustable per cap size and material hardness. Mounting holes and locating slots can be customized for existing holders. Edge‑grinding can be optimized. No fixed standard sizes, customized according to equipment and raw‑material conditions.
Operation Notes
Fasten tool‑holder firmly to avoid blade shifting at high‑speed. Control feed rate properly; avoid over‑load cutting thick‑wall caps. Slow down feed when plastic sticking occurs. Replace blades with chipped or dull edges. Dull blades only squeeze caps and produce many defective parts.

FAQ:
Q1: Can this blade cut composite bottle‑caps with rubber sealing gaskets?
A: Yes. Rubber tends to cause material sticking, regularly clean edge residues during production.
Q2: Is customized cutting‑in angle available?
A: Yes. Angle shall match cap wall‑thickness and machine speed; improper setting causes incomplete cut or edge chipping
Q3: How to tell when blades need maintenance in continuous recycling lines?
A: Excessive burrs, incomplete splitting, caps squeezed but not cut mean dull edge, please maintain or replace in time.
Q4: Can blade shape and mounting positions be customized for non‑standard old‑machine holders?
A: Non‑standard customization is available. Providing original blade sample helps accurate dimension matching.
Q5: How to improve plastic‑sticking issue in production?
A: Adopt higher‑finish edge grinding, moderately reduce feed speed, regularly clear plastic residues on cutting‑edge.
