TKM series heat treatment furnace
Shortens total lead time by 20%.
Saves energy by using high-efficiency regeneration gas burners.
Reduces CO
2
emissions by more than 30% to improve environmental performance.
Significantly reduces furnace body surface temperature by using a new heat-insulated structure.
S-TKM series heat treatment furnace
Compact and slim continuous furnace designed to save space.
Demonstrates productivity that is approximately three times that of conventional batch type furnaces.
Significantly reduces energy costs.
Hybrid type continuous gas carburizing furnace
Uses a tray pusher system and a roller hearth system together.
Reduces energy costs by approximately 40% through use of high-efficiency regeneration gas burners.
Reduces CO
2
emissions per unit weight by approximately 30%.
Roller hearth type continuous high temperature carburizing and quenching furnace
Use of large-capacity regeneration gas burners provides the ability to rapidly raise temperatures.
Use of a large-airflow diffusing fan minimizes temperature distribution.
Shortens carburizing time to significantly reduce treatment costs.
Soot free endothermic gas generator
Heating carried out by swirl flow type regeneration gas burners significantly reduces production costs of converted gas.
New mechanisms such as double-path type retort, pulseless blower, and a special heating system are employed.
Electrical heating gas generators that can be installed in the same size area as those of gas heating type gas generators are available.
Carbon Potential Meter
This meter can directly measure the carbon concentration in the atmosphere gas that is used for heat treatment (carburizing, thermal refining, etc.) of steel.
Highly advanced measuring equipment that is reliable and easy to operate.
Cell type vacuum carburizing furnace
Reduction of lot-to-lot variation by small-lot production, and enhancement of quality characteristics
Reduction of logistics cost and inter-process inventory by equipment in-shop operation
Enhancement of equipment operation rate by meeting variations in demand and production
Start and stop operations that help satisfy the production volume by controlling the temperature and atmosphere independently for each chamber
Metal hot zone high temperature vacuum furnace
Stable operation in a vacuum at 2200℃ and an H2 atmosphere at 1800°C
Reduction of maintenance costs by designing hot zone deformation and consumption measures
Homogeneous heating with uniform temperature distribution
Fully automatic operation by program
High temperature vacuum degreasing sintering furnace
Costs reduced by continuous single cycle operation during the sintering process
Energy saving design heating chamber with excellent high temperature characteristics
Homogeneous heating with uniform temperature distribution
Highly reliable compact chamber
Vacuum washer
Reduced prices as a result of using products made in India that have quality equal to those made in Japan
High-level washing quality achieved by vapor cleaning, endless shower cleaning, and highly efficient reclamation equipment
Reduced costs as a result of reducing discharge and recycling 70 L of washing liquid
Reduced number of problems as a result of using a simple structure without a transport mechanism in the washing room
Horizontal-type plasma nitriding furnace
Easy control of compounds
Significant reduction of gas and electricity consumption
Prevention of nitrogen build-up by just covering the case
Vertical-type plasma nitriding furnace
With its built-in heater, this furnace demonstrates characteristics that are superior to those of conventional ion nitriding furnaces.
Uniform temperature distribution is obtained.
Temperature zone control enables large items of equipment to be used to carry out uniform bulk treatment.
Since the plasma discharge process is gentle, the surface condition (surface roughness) of workpieces is almost unchanged.
