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.

⚙️ Wide Material Compatibility Applicable to coils of various specifications. Suitable for cold-rolled, hot-rolled, silicon steel, stainless, colored, aluminum coils, and all plated/coated coils.

🔄 Automated Production Line Proper layout, easy operation, highly automated and high production efficiency — covering uncoiling, pre-leveling, cropping, slitting, and recoiling.

🔩 Complete Line Components Consists of loading cart, uncoiler, slitter, scrap winder, cropping shear, tension controller and coil recoiler. Loop bridge, pinch and deviation corrector are equipped between each machine.

🏭 Integrated Technology This automatic coil processing line is an integration of mechanical, electrical, hydraulic and pneumatic technology.

Frequently Asked Questions (FAQ)

Q What types of materials can the slitting machine process?

The slitting machine is compatible with a wide range of materials, including cold-rolled and hot-rolled coils, silicon steel coils, stainless steel coils, colored coils, aluminum coils, and all sorts of plated and coated coils, making it suitable for diverse industrial applications.

Q What is the maximum coil weight and thickness this line can handle?

The line supports coil weights up to 35T. Depending on the model, it can handle material thicknesses ranging from 0.5mm (for the 3×1600 model) up to 20mm (for the 20×2500 model), covering a broad spectrum of industrial requirements.

Q What industries commonly use the HR coil slitting line?

The HR coil slitting line is widely used across automobile manufacturing, home appliance production, construction materials (such as cabinets, kitchenware, doors and windows), hardware products, containers, electronic appliances, light industry, and food packaging industries.

Q What components are included in 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 rolls, and deviation correctors are also equipped between each machine to ensure smooth and accurate operation.

Q How is the precision and durability of the knife shafts ensured?

The knife shafts and frames undergo a series of precise processing steps including turning, high-frequency treatment, grinding, and chrome plating. These processes ensure high rigidity, dimensional accuracy, and long service life of the core cutting components.

Q Can the slitting line be customized for different strip widths and number of slitting strips?

Yes. Different models are available to suit varying strip width requirements — for example, the 3×1600 model supports a finished width of ≥40mm with up to 13 slitting strips, while the 20×2500 model supports ≥100mm finished width with up to 4 slitting strips. The line can be configured to meet specific production needs.
