Our products have been used in most of the Japanese satellites produced in the last 30 years. As for the products for our satellites clients, 30 % are a one off only, 50 % are several times, and the remaining 20 % are ongoing clients.

Combustor cases – Having processed the cases for Genx, PW1100G, PW4000,Trent1000 engines (see Page8 ).

Technically capable of processing the rotors that are primary components of Disks and Blisks.

Efficiently coping with changes: with the original operation system that has an exclusive property not seen even in heavy industrial companies, the YSEC Group are capable of adapting to mechanical change without causing delays or wasting time, whilst other manufacturers usually take a few days to change the procedure and operation system.


A team of qualified and experienced professionals: assembling a special team for a project enables all personnel to be made aware of any sudden change in schedule cases and to demonstrate their own efforts to the high-priority tasks.

24-hour-operated and automated manufacturing system: the unattended system unit is equipped with an IC chip to common-attachable pallet for all the machines which has reduced human error and led to 30 percent-less defects so far. In addition, information of the tools are all compiled in a data-base and are completely traceable. Longer operation than manned-systems has led to an increase in productivity on a daily basis, and also raised the cost effectiveness.

Traceability: this system of traceability not only avoids repeating the same mistakes of creating defects, but also enables the control of every area in the manufacturing process such as accepting orders, material conservation, process control, shipment documentation, and our own purchasing management and records, and introducing this system to sub-contractors enables us to have a consistent control operation.
