How we slit our Aluminum coil with our modern slitting machine technology

The manufacturing of aluminum products involves a critical process called slitting, which involves cutting large coils of aluminum into narrower coils or strips. This process plays a vital role in various industries, including automotive, construction, and packaging. In slitting, the coils are first unwound, flattened, and then fed through a set of rotating circular blades, which cut them into narrower coils or strips of the desired widths. The narrower coils or strips are then coiled and packaged for further processing. This process requires precision and accuracy to ensure that the strips are cut evenly and without any deformities, which can affect the overall quality of the end product. Understanding how the slitting process is carried out can provide valuable insights into the production of high-quality aluminum products.

Coil Inspection and Preparation

Before slitting begins, the aluminum coils undergo inspection to ensure they meet quality standards. Any defects or imperfections are identified and marked for removal.


The coil is then placed on an uncoiler, where it is unwound and fed into the slitting machine. This machine will slit the coil into narrower strips according to the desired width specifications.


The slitting machine uses circular blades to cut the aluminum coil into strips of the desired width. The number of blades and their positions can be adjusted to achieve different strip widths.

Edge Trimming

After slitting, the edges of the strips may be trimmed to remove any irregularities or burrs. This ensures that the strips have clean, smooth edges.


Once the slitting process is complete, the narrower strips are recoiled into smaller coils. These coils are then ready for further processing or shipment to customers.

Quality Control

Throughout the slitting process, quality control measures are implemented to ensure the accuracy and consistency of the slit coils. This includes checking the width and thickness of the strips, as well as inspecting for any defects.

Packaging and Shipping

The slit coils are then packaged according to customer specifications and prepared for shipping. Proper packaging is essential to protect the coils during transit and storage.

In conclusion, the slitting process is a crucial step in the production of aluminum products. By understanding how this process is carried out, manufacturers can ensure the quality and consistency of their products, meeting the needs of various industries that rely on aluminum coils and strips.
