Precision cutting or slitting allows many companies to convert different packaging materials, such as tape or plastic film, to a custom size for easier application. Custom-sized products offer many benefits, including reduced product waste, greater design flexibility, and material cost savings. There are many methods of precision cutting and slitting available, so we thought it would be helpful to go over a few of the options for you.

Methods of Precision Slitting

Rewind Slitting

During the rewind slitting process, a master roll is unwound from its original core before it reaches the blades of the slitter. Once it’s been cut to the desired size, the machine takes the material and rewinds it onto a new core, which is sometimes called a recovery core. Rewind slitters have the ability to make multiple cuts simultaneously and rewind onto variable core sizes.

Lathe Slitting

Lathe slitting is sometimes called log slitting because during the cutting process, an entire master roll is sliced without unwinding the material first. A large blade cuts into the master roll to create a new roll at the desired width. This type of slitting provides rapid conversions and can be programed for high-volume production.

Methods of Precision Cutting

Laser Cutting

During a laser cutting application, a controlled high-power laser is used to create a specific shape or cut in a material. Laser cutting is excellent for providing both the quick creation of prototypes and long runs of an infinite variety of parts on one roll for kit creation. Laser cutting provides the benefit of creating highly controlled micro parts, and there are typically little to no tooling costs.

Die Cutting

Die cutting allows for the creation of fast and accurate parts in a variety of shapes and sizes. These parts can then be provided on easy to use rolls or as individual sheets. During the cutting process, a die press is formed into the specific shape and structure you need to enable compression of a material into that shape.

Waterjet Cutting (Pictured Above)

Waterjet cutting is ideal when working with certain materials such as foam, metal, stone, composite, or laminate materials. Waterjet cutting rinses away any fine particles that would gather on cut surfaces, which is common with materials like foam. This helps better protect products that will be packaged in that material, especially if they have easy to scratch surfaces. Waterjet cutting also eliminates fracturing, chipping, or thermal stress on a material while reducing most finishing operations.

Plotter Cutting

A large XYZ Plotter machine is the right solution for large-scale and nested parts that are made from both flexible and rigid materials – without the need for tooling. A computer moves the knife to create the desired outcome.

As you can see, there are many options for businesses who need to convert materials into custom sizes for their application. Whether you’re slitting large master rolls of tape or plastic sheeting, you can get the roll widths you need. There are also precision cutting methods available for creating unique shapes and sizes of a material, so you can avoid cutting it on the job and creating excess waste.
