Custom Manufactured Cut-off Blades

When it comes to extrusion, profile, and tube cut-off blades, there are a wide variety of details to consider. From the type of blade function down to the most incremental of size specifications, Leverwood is here to help. Let us solve your applications issues.

Here are just a few examples of cut-off blades we manufacture and provide to handle a variety of applications.

Straight Edged Blades

Leverwood produces straight edged blades to work on all the major fly-knife extrusion cutting machinery brands. Our blades are well suited to cut both soft and rigid plastic profiles, formed and lined rubber products, as well as many other extruded materials.

Parison Cut-off Blades

Commonly called stab knives, jab knives, or trim knives, parison blades are an integral part of the blow molding process. This process produces hollow plastic products such as bottles, containers, automotive parts, and medical components.  Parison blades cut the parison prior to the final forming stage.

Radius Edged Blades

Leverwood radius edged blades are the perfect after-market addition to your extrusion fly-knife cutting operation. These blades are well suited to cut both soft and rigid plastic profiles, formed and lined rubber products, as well as many other extruded materials.
