SURFACE TREATMENT
We propose "optimal" products with a diverse range of technologies and a lineup.
Our surface treatment lineup
-
Salt Bath Nitriding PS(Prevents Scoring and Scuffing)/PW(Prevents Wearing) treatment
Deep nitrided layer is formed by low-temperature nitriding and short-time treatment using in-house developed salt bath agent.
-
CERAC-C (CVD)
A high-purity gaseous raw material is chemically reacted in a high-temperature state of about 1000℃ by a decompression-type facility, and an ultra-hard compound (ceramic) with little defects and impurities is coated.
-
CERAC-P (PVD)
Carbide compound (ceramic) is coated at low temperature (500℃ or less) by ion plating.
-
Gas Sulfonitriding Treatment (PSG)
Taking advantage of the features of gas nitriding, complex shapes such as deep holes, stop holes, and fine holes can also be treatment.
-
PX (Plasma Nitriding)
There is almost no change in the nitrided surface without the compound layer, and the properties are good.
-
AMINIT SS (Nitriding added Compressive Stress)
Improved heat check resistance of die casting type by applying high compressive residual stress.
-
High-Ten CERAC (Physical Vapor Deposition)
PVD treatment suitable for cold press forming including High tensile strength steel by coating flaw (pinhole, droplet) control.
-
SX-CERAC (Compound PVD)
Ultrafine particle peening is combined with various PVD coatings to achieve a long service life through the synergistic effect of the sliding property of the hard film and the excellent holding force of the processing oil.
-
AMICOAT-C (Compound PVD)
By combining various PVD coatings with a special nitriding treatment, peeling resistance comparable to that of CVD coatings and a long service life can be achieved.
-
AMICOAT-DP (Compound PVD)
Next-generation new coatings to prevent burning and adhesion of molten aluminum. Dramatically improved aluminum erosion damage resistance and wetting resistance.
-
AMICOAT-H (Compound PVD)
New coating that meets the characteristics of warm and hot dies. Abrasion resistance is achieved even at high temperatures.
