Chuhatsu R-series High-Vacuum system

Chuhatsu R-series High-Vacuum system

CHUHATSU’s vacuum system uses BUSCH rotary vane type, ANLET dry roots type vacuum pump, achieving almost complete vacuum, required in the die cast industry, making it stable and high-cycling it. Also equipped with vacuum tank trap and vacuum trap, and by standardizing the parts, its delivery in a short time is possible.

[Company Profile]

Founded in 1969, headquartered in Tokyo, Japan, the company specializes in providing services and designing and manufacturing equipment related to impregnation technology.
It focuses on the development of impregnation-related devices such as impregnation equipment, impregnation agents, vacuum devices, and also offers impregnation processing services for castings and sintered parts.

 

[Product introduction]

High-vacuum system for die casting that experience of impregnation technology has brought.

 

High-vacuum unit for die casting at Chuhatsu is adopting Busch-made rotary vane type vacuum pumps, which was developed by reliance and experience in impregnation technology. It became possible getting a vacuum level that is close to a perfect vacuum that is required in die casting industry, and it’s made stability and high cycle a reality.

A vacuum-tank that reduces evacuation of tank, too. Thus that’s one upper vacuum system that pursued high vacuum in die casting industry.

 

[Product introduction]

  • Integrated Vacuum System

    • The integrated manufacturing that achieved lowering cost.
      The 60L vacuum tank, and the trap that protects the vacuum pump from foreign materials are produced through the integrated manufacturing by founding and plate and metal work. Low cost is also achieved by reducing the number of the vacuum unit’s parts.
    • The compact size design that supports space reduction.
      The compact sized design, integrating the vacuum tank and the trap, allowed the integrated manufacturing by founding and plate and metal work. This is the Vacuum Unit that made possible supporting for saving space, keeping high  performance that enabled high degree of vacuum, close to complete vacuum.
    • The vacuum pump slide installation that improved the maintainability.
      In addition to allow high degree of vacuum in a short time, through the rotary vane type vacuum pump that delivers high exhaust capacity, maintainability is also improved by adopting vacuum pump slide installation, achieving higher productivity.
    • Standard color.
      Silver (Designed color – additional cost)

 

  • Standard Vacuum System

    • Various styles for diverse needs
      Compared to integrated designs, the standard type offers a variety of styles to choose from, allowing users to select the most suitable high vacuum device based on their requirements.
    • Superior performance
      Compared to integrated designs, the standard type can be equipped with more advanced features such as vacuum chambers, vacuum traps, and vacuum pumps, providing a stable and highly efficient production environment.

  • High Speed Shutdown Valve Control Unit

    • High cycle time
      Stable valve operation even though cycle time is under 20sec.
    • Compatible with other brands of vacuum devices
      Adoptable for dicast machines which are already equipped with vacuum systems produced by other companies.
    • Multi-system control for vacuum valves
      Capable of controlling 2 vacuum valves system with 1 unit (incorporating 2 controllers).

  • TOYOOKI Vacuum Valve

    • High speed shutdown operation
      Shut down speed has achieved high-speed operation of 0.007 seconds by high-speed operation circuit and solenoid.
    • Gigh-speed operation
      Realized high-speed operation by actuator motion of depressure circuit.
    • High interrupting force
      Improved shut down speed by high-speed operation circuit and solenoid. (1000N)
    • Shortening Takt time 
      The chuhatsu controller has allowed cycle time reduction.
