This year marks the 50th anniversary of Gifu Seiki Kogyou's founding. We have carried out production activities based on the management philosophy of our founder with the customer first in mind. We would like to express our heartfelt gratitude to our customers and all other people who have provided us with the necessary support to come this far. For many years, Gifu Seiki Kogyou has been honing our skills in the manufacturing of parts, mainly metal press work for electronic parts, medical equipment, and more. We have been engaged in the improvement of our technology and quality, especially in the area of drawing, which requires a high degree of difficulty in die design. Our achievements have now been recognized, and Gifu Seiki has earned an excellent reputation for our drawing capabilities. Although we are facing harsh business conditions, we will continue to make efforts to make even greater contributions to society by utilizing the technical capabilities that our predecessors have cultivated since our founding.

We are a manufacturer specializing in test jigs for semiconductor inspection and evaluation tests.
We offer IC sockets, connectors, test heads, and other test jigs for device evaluation.
We are able to provide high-quality products with short delivery times at competitive prices by implementing our own integrated product design, processing, and assembly in-house.

There are many steps involved in turning an idea into reality, from the production of the product to its completion. We provide one-stop services from the design stage to the production, inspection, and final assembly of the parts providing solutions to your problems such as which materials and plating are suitable, where to order prototypes, how to guarantee the accuracy of the parts, and who is in charge of the assembly.
We handle a wide variety of materials such as metal, resin, glass, and more, and we specialize in high-mix, low-volume parts production.
We have also added a 3D printer, so if you provide us with your data, we can use it to manufacture your parts.
