Industrial
Knives and Cutters

 

Since its establishment in 1925, TOYO KNIFE has accumulated a great deal of expertise in manufacturing industrial knives to meet the diverse needs of its customers.
With high-quality, high-precision products for cutting all kinds of objects and highly functional services, we provide more value to our customers.

Metal foil, Film and Tape

The slitting process is indispensable for cutting long sheet materials, and it covers a wide range of material types, as well as raw material widths and slit widths.
Slitter knives (upper and lower knives) are suitable for slitting thin materials, and the standard method is to use the upper and lower knives with zero(”0”)clearance (no gap).
Based on our half-century of experience and data obtained from various tests, we provide knives that meet users’ needs and contribute to improving the quality of all kinds of products in various industrial fields.
We provide knives according to the specifications of the order, such as the finishing accuracy of the knife edge, which determines the slitting quality, the thickness of the lower knife, which determines the width accuracy of the workpiece to be slit, and the height dimensions of the knife.

Paper and Corrugated paper (Carton) box

Circular knives for paper and pulp cutting are indispensable for slitting sheet materials.
Sharp slitting quality is required, so the knife edges are precisely ground and finished to customer specifications.
Knives for slitting corrugated sheet grooves are made of materials with excellent abrasion resistance for slitting strong and thick corrugated board, and can be manufactured in a variety of shapes to suit customer needs, with a uniform finish without crushing the slitting surface.
The high durability model (CIKC-1) and the paper dust reduction model (CIKC-2) have been approved as “Excellent Products” by Miyagi Prefecture.

Iron, Non-ferrous metals

Knives for cutting steel used in automobiles, shipbuilding, pipes, etc. and non-ferrous metals such as aluminium.
Various shapes of knives can be manufactured, including straight knives, circular knives and knives of different shapes.
We have a wide range of original steel materials for cutting tools.
The above steel materials are carefully selected and manufactured according to conditions such as the thickness and tension of the material to be cut.
We can also process the shape of the cutting edge into an arc shape and perform various surface treatments to prolong the life of the knife.
Our advanced processing technology, backed up by many years of experience, enables us to provide high-quality products.

High precision parts and cutter units

Good Design Award-winning holders for holding the upper blade of slitter knives, plate springs with unique technology, high-precision dies for LCD colour filters, guide rails and cutter units can all be manufactured to meet customer needs.

[Coating Die]

High-precision coating die made by using knife manufacturing technology cultivated over 90 years.
They are used in the coating processes of liquid crystal colour filters, optical films and magnetic tapes, and are the leading edge components of coating equipment.

[Slide Way]

Slide Ways are rails used on the moving sliding surfaces of machine tools, injection moulding machines, forging machines, etc.
The hardened part can be multi-faceted and can be used for all types of sliding surfaces. For carburised products (material SCM), a hardened layer with an effective carburising depth of 1.2 mm can be obtained. All-steel products can also be manufactured.

[Knife Holder & Plate Spring]

The holder is available in different specifications depending on the spring (coil spring or plate spring) set with the knife, but the plate spring specification is recommended to ensure stable contact pressure for improved cutting quality.

[Cutter Unit]

Our cutter units contribute to excellent reproducibility of slitting conditions and stable slitting quality.
We also offer laboratory units for research and development departments, which were developed from a different perspective from units for mass production slitters, for example, for “easy slitting to evaluate the performance of new materials” or “to find the best cutting method for commercialisation of newly developed materials.
