Plastic, film
The film industry has extremely high requirements for cutting flatness, no burrs, and no dust. Henglida's precision blades are mainly used in the following core areas:
Slitting of thin films:
Application scenario: After the production of large rolls of film (such as packaging film, capacitor film, optical film), it is necessary to accurately cut them into narrow rolls of different widths using a slitting machine.
Use of cutting tools: ultra-thin three hole blade, circular slitting upper and lower blades, razor blades, air pressure knife set.
Industry pain point solution: Solve the problems of film drawing, ruffle edges, and dust generation during high-speed slitting to ensure neat winding.
Lithium battery separator Slitting:
Application scenario: The slitting of lithium battery separators in the field of new energy has almost stringent requirements for the material and processing accuracy of the blades.
Tools used: tungsten steel (hard alloy) disc blades, ceramic blades.
Industry pain point solution: Maintain extremely high wear resistance, avoid metal shavings from blade wear that contaminate the diaphragm, and ensure battery safety.
Bag Making&Sheeting:
Application scenario: Continuous high-speed cutting or punching on the production line of plastic packaging bags and food packaging bags.
Use of cutting tools: toothed cutter, integrated bag cutter, round hole/butterfly hole punching mold.
2、 Plastics Manufacturing&Recycling Industry
The plastic industry covers the entire industry chain from raw material particle manufacturing, product molding to waste plastic recycling, in which cutting tools play a dual role of "crushing" and "molding":
Plastic Recycling&Crushing:
Application scenario: Centralized crushing and recycling of waste plastic bottles (such as PET bottles), plastic buckets, machine head materials, and water outlet materials.
Tools used: Strong crusher blades, shredder blades (multi claw blades), and reducing capacity machine blades.
Industry pain point solution: requires extremely high impact toughness and wear resistance to prevent the blade from shattering when cutting hard plastics or foreign objects.
Pelletizing plastic:
Application scenario: After modifying or recycling plastic raw materials, the hot melted plastic strips are cut into uniform particles at the end of the extruder.
Use of cutting tools: underwater pelletizing knife, rolling cutter, pelletizing machine flying knife.
Industry pain point solution: Ensure a smooth cutting surface, uniform particle size, and reduce the generation of continuous particles and powder.
Trim Recycling of Plastic Edges:
Application scenario: On the sheet and board extrusion production line, real-time cutting of irregular edge waste and direct return to the crusher.
