Doctor Blade
We supply 11 metal types and 4 plastic series so that the blade can be selected to match the ink and cylinder conditions. The range runs from 580 Hv steel to ceramic with a surface hardness of 1,000 Hv, and includes specialty products for rust prevention, streak-contamination control, and long-run printing.
Overview
A doctor blade lineup organized by material and surface treatment
We supply doctor blades for coating and printing processes in 11 metal types and 4 plastic series. Hardness and surface film are selected according to ink type, cylinder conditions, and print run length.
Lineup
Metal doctor blades
| Steel doctor blade | 580~600Hv | A basic model long in widespread use. Craftsmen produce it on proprietary grinding machines, and the blade edge in particular receives proprietary machining built on years of experience and know-how. |
|---|---|---|
| Gold doctor blade | 620Hv | Uses the latest premium steel with a high content of wear-resistant components compared with ordinary Swedish steel. Highly durable, with good contact against the cylinder. |
| R-ST doctor blade (streak-contamination control for process inks) | 580~600Hv | A top-quality steel doctor blade whose edge receives proprietary special grinding. Highly effective against streak contamination in light halftone areas. |
| Stainless steel doctor blade | 590Hv | Made from Swedish stainless special alloy steel for high durability and corrosion resistance. It handles demanding printing conditions involving water-based or acidic inks. |
| Ink-splash prevention doctor blade | 580~600Hv | A product built on an original new idea. It reduces wear at the cylinder edge, making it ideal for long print runs without changing the doctor blade. Produced to customer order. |
| Doctor blade for black ink | 580~600Hv | Uses high-quality Swedish steel with precision-ground edge for excellent cutting performance. It effectively reduces the print contamination that commonly occurs with black ink. |
| Ceramic doctor blade | Surface hardness 800–850 Hv / 850–900 Hv (standard surface hardness) / 900–950 Hv / 950–1,000 Hv | A high-quality product developed by combining proprietary grinding and surface technologies. Film adhesion and wear resistance are markedly improved over previous products. |
| Root doctor blade | Surface hardness 800–850 Hv / 850–900 Hv (standard surface hardness) / 900–950 Hv | The surface film uses a highly lubricating component to pursue smooth running and cutting performance. Particularly suited to water-based inks, with a white-only type also available. |
| Soft doctor blade | Surface hardness 650–700 Hv (standard surface hardness) / 700–750 Hv / 750–800 Hv | A thinner surface film coating gives low hardness while retaining wear resistance. It reduces damage to the cylinder. |
| Nickel alloy doctor blade | Surface hardness 600–650 Hv / 650–700 Hv (standard surface hardness) | Coated with a special nickel alloy film. The low-hardness surface film delivers a strong anti-corrosion effect. |
| Backup blade | — | The backup blade is also an important factor in getting the best from a doctor blade. A range of sizes is available. |
Plastic doctor blades
Blade edge shapes — PET-S (flat) / PET-D (stepped). The available edge shapes differ by series.
| PET-S, PET-D series | Thickness 0.35 mm / polyester | Coil, cut [100 m packing unit (standard)] / single-ply base material |
|---|---|---|
| HI-PET series | Thickness 0.5 mm · 0.6 mm · 1.0 mm / polyester | Coil, cut — 100 m packing unit (standard) for 0.5 and 0.6 mm, 30 m packing unit (standard) for 1.0 mm / single-ply base material (0.5 mm), two-ply laminated (0.6 and 1.0 mm) |
| HI-PE series | Thickness 1.0 mm · 1.5 mm · 2.0 mm / high-density polyethylene | Cut (cut lengths up to 1,800 mm) / single-ply base material |
| HI-POM series | Thickness 0.8 mm · 1.0 mm · 1.5 mm / polyoxymethylene | Coil, cut — 30 m packing unit (standard) for 1.0 mm, 1,000 mm cut lengths for 0.8 and 1.5 mm / single-ply base material |
