      Product Details

      Product Introduction

      The slitting machine is a key piece of equipment in industry for cutting wide metal or non-metallic coil materials into several narrow strips of the required width along the length direction. Its core working principle is to continuously roll-cut the material through the rotation of the upper and lower circular disc knife shafts.

      The following is a comprehensive introduction to the core features of the slitting and shearing machine:

      Core Structure & Unit Composition

      The core structure mainly consists of upper and lower knife shafts, fixed/movable frames, and a synchronous lifting mechanism. The knife shafts and frames undergo precise processing (such as turning, high-frequency treatment, grinding, and chrome plating, etc.) to ensure the rigidity and accuracy of the equipment.

      Frequently Asked Questions
      What types of materials can a coil slitting line process?
      The coil slitting line is designed to process a wide range of materials, including cold-rolled and hot-rolled coils, silicon steel coils, stainless steel coils, colored coils, aluminum coils, and various plated and coated coils. This versatility makes it suitable for industries such as automotive, home appliances, construction, and packaging.
      What is the maximum coil weight and thickness the slitting machine can handle?
      Depending on the model, the slitting line can handle coil weights of up to 35 tons and material thicknesses ranging from 0.5mm up to 20mm. For example, the model 20×2500 handles thicknesses from 6mm to 20mm with a coil weight capacity of 35T.
      What is the typical slitting speed of the production line?
      The slitting speed varies by model. Lighter gauge models (such as 3×1600 and 4×1600) operate at up to 50 meters per minute, while heavier gauge models (such as 16×2500 and 20×2500) operate at up to 20 meters per minute, ensuring both precision and productivity.
      What components are included in the complete slitting production line?
      The complete production line consists of a loading cart, uncoiler, slitter, scrap winder, cropping shear, tension controller, and coil recoiler. Loop bridges, pinch rollers, and deviation correctors are also installed between each machine to ensure smooth, accurate, and continuous operation.
      How is the accuracy and rigidity of the slitting machine ensured?
      The knife shafts and frames undergo rigorous precision processing including turning, high-frequency heat treatment, grinding, and chrome plating. These processes ensure the structural rigidity and dimensional accuracy of the equipment, resulting in consistent cut quality and extended service life.
      Which industries commonly use coil slitting lines?
      Coil slitting lines are widely used across many industries, including automobile manufacturing, home appliance production, construction materials (cabinets, kitchenware, doors, and windows), hardware products, containers, electronic appliances, light industry, and food packaging.
