Main Features
Precision Straightness: Guaranteed high-level straightness across the entire length, essential for achieving a uniform cut on wide materials.
Micro-Adjustment Slots: Custom elongated slot machine blades allow operators to finely tune the knife position for perfect alignment and gap setting.
Custom Profile Machining: Capable of producing the complex side notches and steps required for precise positioning and function in specialized machine guides.
Versatile Material Use: Optimized to serve as precision ground rubber cutting blade, high speed film cut off blades, and heavy-duty paper trimmers.
Superior Edge Durability: Advanced heat treatment of D2 or HSS ensures long life for D2 steel paper guillotine bottom knife and similar applications.
Advantages
Minimized Waste: The precise trim action reduces material fraying, cracking, or crushing, saving material costs.
Extended Service Life: High-quality steel and grinding reduce the frequency of blade replacement and maintenance.
Custom Fitment: We provide custom length packaging slitters and trimming knives that precisely match the specifications of your existing machine tooling.
Reduced Vibration: The robust structure and accurate fit minimize vibration during high-speed plastic sheet fly shear knives operation.
