High-End Custom Converting Services

Material converting services provide an effective way to alter standard materials into highly useful products. Rathbun offers the following types of custom converting services for your specific needs.  


Kiss-cutting is a popular method of cutting adhesives and foams. The process involves cutting the top layer of material, leaving a thin backing on the converted material. 

Rotary Die Cutting

Rotary Die Cutting is a highly effective method for cutting parts that require high volume and extremely close tolerances. This process can also include can also include Kiss-Cutting, Through Cutting, Scoring, and Perforated Cutting. Finished parts can be produced in roll form or individually loose cut.

Laser Cutting

Laser cutting is the quickest way to produce prototypes and proof-of-concept parts. We can take your drawing file and convert it into a part within minutes. Whether it is a simple or a complex part, laser custom converting services can quickly and effectively create a wide range of parts.

Custom Die Cutting

Custom die cutting services are regularly utilized for thicker materials and lower production runs.  Rathbun offers a wide range of converting services.  Die cutting ranges from very small steel rule dies to as large as 36” wide x 80” long.

Slitting & Rewinding

Log Slitting, also known as Baloney Slitting, is a shearing process that converts a large master roll into narrow rolls by driving a rotating blade into the rotating log. Once the material is completely slit through the supporting three-inch core, the spools are removed from the mandrel. This process can be used for materials with or without adhesive backing. We provide extensive slitting capabilities from Slit Rewind functions to Baloney Slitting (up to 72” in width).

Lamination Service

Lamination is a manufacturing process used to bond multiple layers of unlike materials together to create a composite product. Most common is the lamination of pressure sensitive adhesives (PSA) to one side of a material, the primary step before producing gaskets with PSA backing. Rathbun is capable of Hot/Cold lamination up to 60” in width. Lamination service is also achieved as an inline setup during the manufacturing of Rotary Cut Parts.
