Need precision-cut, high-quality steel slitting for your next project?

Steel is an alloy of iron that is mixed with carbon which improves its strength and durability. Combine these properties with its low cost and you have a perfectly-suited alloy for a multitude of uses in various end applications, including (but not limited to) automotive, infrastructure, and appliance/HVAC.

Enter the role of steel processors. Steel processing companies like National Material Company provide manufacturers with the right steel material for their industry. This article will focus on the topic of steel slitting and how the slitting process works.

Steel slitting is a steel manufacturing process wherein a coil of steel is slit into the lengths and widths specified by the end application. This process requires machinery lines equipped with a decoiler, slitter, and a recoiler — to achieve the end product: slit steel coils, or “mults.”

An operator will feed the steel coil onto the uncoiler mandrel. The uncoiler unwinds the master coil, feeding it into the slitter head where the steel will be slit into narrow mults (strips) by rotary knives. The operator then inspects the individual mults to ensure the gauge width and edge condition meet required specifications. The mults will then travel through a looping pit to insure stress-free and camber-free recoiling of the slit material. Individual mults are then banded and packaged to specific customer requirements.

This process requires careful precision. Leading steel processing company NMC operates several steel service centers in the United States and Mexico using robust precision slitting machines equipped with advanced technology in software, tooling practices, and hardware. This helps National Material Company streamline their production and reduces their time to delivery. NMC thoroughly checks their equipment for alignment and regularly calibrates their machine line to help reduce scrap and overall cost.

National Material Company spent decades perfecting the art of steel processing to provide only the best to their clients, earning their position as a top steel processor. NMC guarantees top tier quality for all of your steel supply needs, and they also offer a wide variety of steel processing capabilities.

What is Precision Slitting?

In the metal processing world, every new contract comes as a new and customized challenge. Increased demand for steel coils with finer width and length parameters have ushered in an era of more robust precision slitting – with technological advancements in slitting equipment, software, and tooling practices fueling the wave.

Slitting is a metal manufacturing process wherein a coil of material, such as aluminum or steel, is slit into the lengths and widths specified by the end application. As the material runs through the machine, the steel rolls are moved through extremely sharp circular blades, making the cuts. In order to make the slice, substantial compressive forces must be applied – and when the forces exceed the tensile strength of the material, it slices. The end product is long strips of material cut to the buyer’s specifications.

A steel slitting machine is comprised of three major parts – the uncoiler, the slitter, and the recoiler. In order to ensure that the quality of the process is optimized, each element must be precisely aligned during setup.

National Material’s breadth of slitting capabilities is of tremendous value to our customers, who know that we have the right equipment to process their orders on time and to the right specifications. Our customers appreciate the high level of precision and quality we offer in our slitting process, as it eliminates the excess material waste that can be produced by their own manufacturing processes creating real value.
