We manufacture a large number of highly airtight products. Complex shapes are also possible with aluminum-magnesium sand casting!
Our company manufactures a large number of airtight products, such as large pressure vessels and vacuum chambers, and we are confident in our high airtightness. 【Leak-free castings tested for airtightness using a helium leak detector】 We conduct helium leak tests using helium gas, which has a small molecular diameter, making it the most sensitive method for leak detection and providing accurate results even for minute leaks. We offer high airtight products without leaks for high-pressure gas containers used in power circuit breakers and vacuum containers for semiconductor manufacturing equipment, where airtightness is critical. *For more details, please refer to the PDF document or feel free to contact us.
