Vacuum chambers

Vacuum chambers are containers for vacuuming the interior and are the central components of sputtering, vacuum deposition equipment for Semiconductors, Liquid crystals, Organic EL.. and Medical and Pharmaceutical Sterilizers.

Our vacuum chambers

Kyoyu Seisakusho is good at in small and medium-sized square chambers that can be effectively installed even in a small space, mainly stainless steel, welding structure, non-mass production, and full custom-made, and has many supply records in vacuum chambers.

In companies that own large machines, the production of small and medium-sized chambers in small lots with a welding structure tends to be costly because the setup man-hours is spent extra. but our company uses the manufacturing know-how accumulated to thoroughly suppress costs and we have responded to customer requirements.

In addition to machining and welding, we are also working to enhance our services by cooperating with business partners to handle a wide range of procurement of materials and vacuum parts and surface treatment.

Production range

Work materialStainless steel (SUS304, SUS316), SS400
Joining methodsTig welding, Semi-automatic welding 
Maximum size that can be manufacturedAround 1000mm square
StructureWelded structure by Tig welding
SpecificationsWe will flexibly respond to the various specifications according to heating temperature and vacuum degree such as following conditions.
- A chamber used in a low temperature range of about 150 ° C or less and that is sealed by the O-ring of the JIS flange
- A chamber used in a medium temperature range of about 300 °C or less and that is sealed by a metal gasket of the ICF flange.
- Without using a flange, it is also possible to process the O-ring groove directly on the chamber wall.
RemarksIn order to increase the degree of vacuum, we will respond to the necessary surface treatment and heat treatment. 
"Buffing , Electrolytic polishing" to improve the surface accuracy of the inner wall surface of the chamber 
"Baking treatment" to prevent the generation of residual gas in advance by gasifying gas molecules adhering to the inner wall of the chamber by cleaning or surface treatment by heat treatment.
