As explained by Mr Katsuhiro Kamimura, it is very important that the company peoples are able to understand and take care of the whole process. Everything is linked, and such tremendous precision results can not be obtained without a great polyvalence of the staff. So the company is encouraging people to move from studies to manufacturing, from manufacturing to quality and so on. Hakkai is now using 9 TopSolid’Mold seats.
The complete mould design is done in 3D, and it allows avoiding errors and improving greatly the precision of the parts. Machining is performed mostly using wire Edm cutting. It was something unbelievable for Christian Arber that such precision could be reached and mastered when so much parameters and processes are involved. Integration between design and manufacturing, not only reflected in the means (CAD/CAM, machines...), but also in the staff brains. A culture is certainly the key point of this incredible technical success story.
