Analysts
have said they do not expect The highest level of technology we offer to our clients has been acquired and polished through our tough experiences of meeting the needs of the world top auto parts makers. Collaborating with such parts suppliers has obliged us to do so. Costs and qualities of auto parts required from auto makers have been changing drastically. And it is our role to cope with such changes, while meeting the demand. What we are going to offer our clients are not those ordinary parts makers can supply. Costs of our products are lower than, and their qualities are superior to, those of other similar parts makers. What makes it possible is our experiences and vigorous challenge spirits. It is ideas for quality improvement and reduction of costs, we have actualized, that have made possible what seems impossible to others. Metal processing involving plastic materials is said to require the highest level of industrial technology. Especially deep drawing technology is known as the ultimate one that needs full and variety of knowledge and experiences. Those who are engaged in that technology should have full knowledge about metal processing and pressing and machine tools as well as about ever-evolving metal materials. It is not such a kind of technology as one which every one can master if only he is offered to use same materials and machine tools. We believe that this century is the age of ideas. What is most important is to use, with flexible and abundant ideas, materials and machine tools we can evenly put to use. What is required of engineers is a simple way of thinking, “What makes it possible?” We have achieved that highest-level of Higuchi deep drawing technology by flexible ideas of young Higuchi engineers and rich experiences of experts. |
| SOFT or HARD? The appearance and evolution of CAD and CAM have made it possible for parts designers to draft the shape of metal parts freely, which has inevitably forced us to devise new methods of metal processing we have never experienced. So long as requests from our clients are of such a kind that will improve the quality of their products, and even if they are jobs with enough challenge, we are ready to do our best to meet the requests. We think that it is our role as specialists to meet the requests from specialist clients. It is the attitude like this, we believe, that has sustained and will continue to sustain manufacturing business in Japan. |
Higuchi's cutting-edge technology -----------
| Deep drawing of high tensile steels |
Realization of precise deep drawing of high tensile steels.
The 38mm deep drawn products from 780N/mm2 steel are currently on mass production. |
| Precise welding of deep drawn products |
We are currently welding a pipe inside of the deep draw product from 980N/mm2 steel with dimensional control and stability in 6 seconds cycle. |
Magnesium forming process |
|
Magnesium is futuristic material that is the strongest per weight and can be obtained from sea water. However, since magnesium is so strong that forming it is extremely difficult. Nonetheless, Higuchi’s perseverance through testing using press machines has made mass production a possibility.

|
Weight comparison Made with magnesium alloy 186.2g |
 Made with regular steel 804.1g |
The specific gravity of magnesium alloy is about 1/4 of steel and the strongest per weight among practical use metals. |
|
Higuchi succeeded to form a spring guide used for shock absorbers. It is as hard as metal yet extremely light!| Super thin rectangular drawing |
We are currently approaching the limit of inner gap for the rectangular drawing. Current record : 1mm x 20mm x 25mm depth x 0.3 thickness |
| Deep Drawing | Piercing from inside by one stroke. | Minimize deformation from welding, for positional accuracy. | Precise Blanking same as fine-blanking |
