High-Quality HR Coil Slitting Line from China Suppliers - Reliable Factory Equipment for Metal Strip Processing
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 materials can the slitting machine process?
The slitting machine is capable of processing 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. It is designed for both metallic and non-metallic wide coil materials.
What is the maximum coil weight and thickness this line can handle?
The production line can handle coil weights up to 35T. In terms of thickness, the range spans from 0.5mm (for models 3×1600 and 4×1600) up to 20mm (for the 20×2500 model), depending on the specific model selected.
What industries is this slitting line suitable for?
This slitting line is widely used across many industries, including automobile manufacturing, home appliance production, construction materials (cabinets, kitchenware, doors and windows), hardware products, containers, electronic appliances, food packaging, and general light industry applications.
What is the maximum slitting speed of this production line?
The slitting speed varies by model. Lighter-gauge models (such as 3×1600, 4×1600, and 6×1600) can achieve up to 50m/min, while heavier models (such as 8×2000 and 10×2200) operate at up to 30m/min, and the heaviest models (16×2500 and 20×2500) run at up to 20m/min.
What key components make up the complete slitting production line?
The complete 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 installed between each machine to ensure smooth and precise material flow throughout the entire process.
How is the precision and rigidity of the slitter ensured?
The knife shafts and frames are manufactured through a series of precise processing steps including turning, high-frequency heat treatment, precision grinding, and chrome plating. These processes ensure long-term rigidity, dimensional accuracy, and consistent cutting quality across all production runs.
