【Salt Marking Method】 Our pit-type carburizing atmosphere furnace and case-type carburizing atmosphere furnace are batch-type, allowing us to accommodate small quantities of diverse hardening processes. We offer a wide range of treatments, including deoxidation processing, carburizing hardening, as well as annealing and tempering. If you are facing difficulties with short delivery times due to differences in specifications such as steel types, carburizing depth, and base material hardness, please feel free to consult us. 【Sub-Zero Treatment】 Also known as deep cooling treatment, this process involves cooling below 0 degrees to transform residual austenite into martensite. The benefits of sub-zero treatment include (1) increased hardness, (2) prevention of distortion, and (3) improved wear resistance. It is an ideal treatment for enhancing the high added value of molds and cutting tools. *For more details, please download the materials or contact us.*

Vacuum heat treatment is a method of heating materials to high temperatures in a sealed container that has been depressurized by a vacuum pump, followed by cooling and quenching with nitrogen gas or oil. It is capable of processing at temperatures exceeding 1000 degrees and is widely applied to the quenching of die steel and high-speed steel. Since our establishment, we have specialized in the heat treatment of die steel for metal press molds, optimally controlling the heating and cooling processes to accommodate various shapes. We provide heat treatment that minimizes distortion even for complex three-dimensional automotive molds while maximizing the material's properties. Additionally, vacuum heat treatment furnaces can manage the temperature distribution within the furnace with extremely high precision, making them ideal for heat treatment of precision parts. In particular, heat treatment furnaces that comply with the heat treatment standards for aircraft components (AMS2750) are subject to strict equipment management regulations, with regular calibration of measuring instruments, including thermometers, and system accuracy tests for furnace temperature uniformity, enabling traceable heat treatment. [Features] - Capable of handling complex shapes - Minimizes distortion - Extremely precise management of temperature distribution within the furnace *For more details, please download the materials or contact us.

We also accept consistent manufacturing from processing to surface treatment using the same materials as rollers for mold components. Considering the troubles caused by distortion when outsourcing only heat treatment and surface treatment, as well as the hassle of managing outsourcing, it is reasonable to place orders with a contractor that can handle all processing. Although we are not a specialized processing manufacturer, we are located in a manufacturing cluster area of small and medium-sized enterprises, including Higashi-Osaka, and we have partnerships with reliable processing manufacturers. 【Features】 ■ Consistent production from materials to surface treatment ■ Trouble avoidance through outsourcing only surface treatment ■ Cost reduction through consistent production *For more details, please contact us.

Regarding such rollers, we not only accept processing contracts but also provide consistent manufacturing from materials, processing, to surface treatment. The reason for this is that the tolerance with the shaft is very important for these rollers. Fine coating treatment can produce a high-hardness ceramic coating with excellent adhesion, but the processing process can reach high temperatures, which may lead to distortion (size change or deformation) that cannot be avoided. In such cases, we can address this by performing finishing processing after treatment. To ensure reliable process management, including post-finishing, we consistently accept manufacturing contracts. We have numerous achievements in roll forming of steel plates and bars, as well as drawing rollers for steel wires. If you have rollers troubled by friction and wear, please feel free to consult us. 【Features】 ■ Consistent production from materials to surface treatment ■ High durability ■ High wear resistance *For more details, please contact us.

In the cutting of various steel pipes, traveling press cutters are widely used due to their high productivity. Moreover, the cutting blades experience significant wear due to the impact from cutting and the high surface pressure from contact with the workpiece during operation, making them one of the tools that must be used as consumables. We have implemented fine coating treatment on the cutting blades of press cutters, dramatically improving their durability. By consistently managing the entire process from material selection to processing and surface treatment, we provide high-quality blades. They have been adopted by major steel pipe manufacturers for over 10 years, and we kindly ask you to consider using them. 【Features】 ■ Durability ■ Cost reduction through consistent production ■ There are cases where monthly usage has been reduced to 1/4 *For more details, please contact us.

In recent years, surface treatment technologies that dramatically enhance the durability and wear resistance of precision parts and molds have become essential for improving productivity. Fine coating with ultra-hard ceramic films can form dense carbide coatings without cracks, as it allows for film formation at lower temperatures than conventional CVD. Furthermore, by using a unique vacuum diffusion method, it improves adhesion and achieves excellent durability. *For more details, please download the materials or contact us.*

The molten salt method is a ceramic coating technology in the liquid phase that generates carbides, nitrides, and borides through thermochemical reactions. Among surface treatment methods for steel materials, it is a method that can produce very hard and highly adhesive ceramic coatings. Kentech Co., Ltd. has been committed to this molten salt method since its establishment, integrating heat treatment technology and vacuum technology, and has been engaged in research and development. We will continue to aim for the creation of surface treatment technologies that bring new value to our customers. For more details, please contact us or refer to our catalog.

Kentech's shear blades not only undergo conventional hardening but also feature a unique ceramic coating, demonstrating exceptional cutting performance on stainless steel and high-tensile (high-strength steel) materials. The ceramic coating utilizes vanadium carbide (VC). The VC coating, which has the same cubic crystal structure as diamond, boasts a high hardness of HV3000. Thanks to a proprietary molten salt method, it achieves a level of adhesion that traditional PVD titanium coatings do not, significantly extending the lifespan of the cutting tools.
