Mimasu Kougyou Co., Ltd.

Precision machining of critical safety parts of aerospace instruments

Our main operations include precision machining of critical safety parts of aerospace instruments, rapid transit railway vehicles, electric power generation equipment, etc. We handle diverse processes including vacuum heat treatment, nondestructive testing, and assembly and maintenance of units by integrated production all in-house. We are skilled at precision processing of complicated shapes of difficult-to-cut materials such as stainless steel, titanium, and Inconel. We are skilled at multi-kind, small-quantity and intermittent production thanks to our adaptability and flexibility. Our processing is used in cutting-edge industries requiring excellent safety and reliability, and therefore we have obtained various certifications and accreditations and maintain sophisticated processing techniques and strict quality control. Our principle is “challenging Monozukuri (manufacturing) without compromise”.

Sales Pitch

Realizing the integrated processing of ultra-precision machined parts that require safety and reliability

By using state-of-the-art facilities, our company conducts a wide range of processes in-house, from precision machining to vacuum heat treatment, nondestructive inspection, and assembly/maintenance in clean rooms. Furthermore, through our own supply chain management, we offer integrated production solutions, including carburizing heat treatment, beam welding, surface treatment, and coating.

Precision machining:
Skilled workers with national certifications make the most of approximately 50 machining tools, such as state-of-the-art 3D CAD/CAM, simultaneous 5-axis machining center, and combined machining tools to meet the requirements of highly advanced machining.

Vacuum heat treatment:
We provide AMS-compatible vacuum heat treatment that is accredited by major companies such as Kawasaki Heavy Industries, Subaru, and Mitsubishi Heavy Industries. 

Nondestructive inspection:
Magnetic flaw inspection is available, which complies with ASTM E 1444 standard and is Nadcap-certified.

Supply chain management:
We can offer a one-stop order service through a supply chain which we have built with certified vendors in specialized fields, such as welding, and surface treatment.

We can meet the needs of the critical safety-related parts market, such as aerospace equipment, defense equipment, high-speed railway vehicles, marine equipment, and power generation equipment, which requires exceptionally advanced quality assurance capabilities.
