| PR message | We started our business as a heat treatment company for molds, and have expanded our surface modification business such as nitriding and a wide variety of PVD coatings to meet the needs of the times. |
| The Main Item |
|
| The name of Item[1] | PVD coating “Deep hole type”: diXis-Tin, diXis-TiCN, diXis-TiAlN, diXis-CrN and diXis-Acro |
| Details[1] |
＜Feature＞ General PVD coating is extremely difficult to form a hard-ceramic protective film (TiN, TiAlN etc.) on the inner surface of a deep hole that L (length) / D (inner diameter) ≒ 5. Even on the inner surface of the deep hole, it exhibits the same high hardness and excellent adhesion as a general ceramic protective film. Dramatic life improvement can be expected for molds that are formed with deep hole inner surfaces and for machine parts that slide on deep hole inner surfaces. ＜Lineup＞ - diXis-TiN、diXis-TiCN、diXis-TiAlN、diXis-CrN and diXis-Acro (mainly composed of AlCrN) |
| The name of Item[2] | PVD coating “Standard type”: TiN, TiCN, TiAlN, CrN and Acro |
| Details[2] |
＜Feature＞ “Standard type” is suitable for cutting tools, molds and machine parts. We use the most popular coating process arc ion plating (AIP) method, which is a process to efficiently coat the surface of the target workpieces by evaporating the target material by arc discharge. ＜Lineup＞ 3 types of Ti-based film (TiN, TiCN and TiAlN) and 2 types of Cr-based films( CrN and Acro): - Standard TiN, low-friction TiCN and wear resistant TiAlN have a tract record in a wide range of applications. - CrN has low affinity with resins and copper, makes it ideal for preventing adhesion. - Acro, which is mainly composed of AlCrN, provides the highest heat resistance temperature of 1000°C in PVD coating. |
| Details[3] |
＜Feature＞ For typical PVD coatings (AIP), microscopic irregularities called droplets are formed on the surface. We have developed our own PVD technology (thin film AIP/HCD/UBMS/+polishing) to provide smooth coatings with suppressed formation of droplets. ＜Lineup＞ - Fine FT (Smooth TiN coating) - Fine FG (Smooth TiCN coating) - Fine FC (Smooth CrN coating) - Smooth AX (Smooth TiAlN coating) - Smooth MX (Smooth TiMoN coating) - Smooth CX (Smooth CrN coating) |
| The name of Item[4] | PVD coating “Thick film type”: ViOLA, ViOLA-R, ViOLA-S, Acro9 and Acro9P |
| Details[4] |
＜Feature＞ Die-casting molds have unique forms of damage, such as heat check, erosion and seizure. The film thickness of “Thick film type” is 9μm which is 3 times thicker than the conventional film, and has excellent abrasion and erosion resistance, thus protecting molds used in high temperature molten metal environments. Composite treatment with nitriding of the base material can further improve erosion resistance and heat check resistance. ＜Lineup＞ - ViOLA, ViOLA-R and ViOLA-S (Emphasis on erosion resistance) - Acro9, Acro9P (Mainly composed of AlCrN, Emphasis on anti-seizure) |
| The name of Item[5] | “DLC type”: DLC and DLC-i |
| Details[5] |
＜Feature＞ DLC stands for Diamond-like Carbon, a general term for amorphous carbon structure containing sp2+sp3 hybridized carbon atoms. Due to the structure is similar to diamond, hardness is its main feature. Compare to very expensive diamonds, it can be produced on a variety of material surfaces at lower cost. DLC has an overwhelmingly low coefficient of friction compared to metallic materials, even in a dry process, it has the same friction coefficient as oil lubrication. DLC also can suppress adhesion of soft metals (aluminum alloys, etc.). ＜Lineup＞ - DLC - DLC-i (Hydrogen-free) |
| The name of Item[6] | Nitriding treatment |
| Details[6] |
＜Feature＞ - Improved mold life by surface hardening - Improved durability and wear resistance of molds, machine parts, etc. ＜Lineup＞ - Ion nitriding: 4 units of NDK ion nitriding equipment allow us to handle long and heavy products. - Radical nitriding: Since it is difficult to form a white layer on the surface, composite treatment such as PVD coating is possible after nitriding. - Plasma deep nitriding “Prize”: Next-generation plasma deep nitriding treatment that achieves deep nitriding and high surface hardness while suppressing the formation of brittle compound layers. |
| The name of Item[7] | Vacuum heat treatment |
| Details[7] |
＜Feature＞ Our "Vacuum Heat Treatment" is equipped with a number of vacuum heat treatment furnaces (oil-cooled/gas-cooled), atmosphere tempering furnaces, and sub-zero equipment to quickly respond to your heat treatment needs. We meet our customers' needs by making full use of the know-how and unique technology that we have cultivated since our establishment in 1977. Equipped with a large vacuum furnace (1200 kg) that can handle large and long products. ＜Major heat treatments and steel grades＞ - Quenching and Tempering: Die steel, high-speed steel, alloy tool steel, machine structural steel, etc. - Aging treatment: Beryllium copper, etc. - Solution heat treatment: Austenitic stainless steel - Annealing: High carbon chromium bearing steel, etc |
