Business Overview：Types of Cutting Dies

Using the state-of-the-art systems and skilled know-how to meet the needs of different cutting dies

At

Hara Nukigata Inc.

, we employ the state-of-the-art systems and skilled know-how to meet a wide range of needs for different cutting dies from our customers, such as Victorian and Pinnacle dies, etc.
Relying on our 30 years of solid experience and know-how in manufacturing, we also provide consultancy services to support our customer manufacturing besides providing high-quality dies.

Victorian die

Our technology can meet the requirement of even
the smallest bending radius of 0.3mm

We can also provide large cutting dies exceeding 1m in
size that are very difficult to handle

The Thomson (Victorian) die is used in a wide range of applications, including general paper devices, seals, car interior fittings and FPC foundation. It consists of a die made of SK material and embedded in plywood in a press machine. The die is inserted into a gap made by a laser on a veneer surface. Presently, we can deliver these at relatively short lead-times due to the higher efficiency gained from the introduction of bending machines using design data. However, the expertise of skilled craftsmen such as the adjustment of the bending condition, alignment of the blades etc. is required for important machining works that can be affected by the quality of the cutting die.

Engraving dies

Engraving die is made by cutting a metallic block separately into the blade and base sections by NC machining. Compared to Thomson or etching dies, although the initial cost is higher, the half-cut precision is better and the die life is longer due to the hardness. As re-grinding is possible, it is suitable for mass machining works (normally, it can undergo about 4-6 grindings).

Pinnacle die

Etching dies (corrosion dies) are suitable for cutting fine curves and thin sheets such as labels. Unlike Thomson (Victorian) dies, they do not have any die seams at all. Compared to a conventional etching die which has a rounded tip, the blade tip in a Pinnacle die has been sharpened into a sharp angle. Based on this, it is possible to cut paper and films which conventional etching dies cannot do, as well as FPC foundations that require high precision.

Our company can also provide Side Open Edge (SOE) processing using Pinnacle dies. One of the problems which occur during blanking is clogging due to the accumulation of cutting dregs. A Pinnacle die with SOE specifications comes with an acrylic platform in a set. The machine is designed such that the cutting dregs cut by the Pinnacle die drops to the bottom for proper removal without causing clogging.
We can also accommodate your request for a set order for Victorian and Pinnacle dies. Please feel free to consult with us.

Eagle die

Eagle dies are ones where shape correction and blade height adjustment are carried out in order to reduce the cutting resistance. We supply Eagle dies that can be used for cutting thick objects and those with complex shapes. By combining an Eagle die with a Pinnacle die, the possibilities of the cutting die can be widened considerably.
