The trust that we have earned stems from our ability to provide “reliable cutting parts.”

“Despite the small size of the items we produce, the scale of our work is sizable”
The items such as screws and shafts that are processed on automated boards are indeed small; however, the products in which these small items are applied include smartphones, TV sets, and cameras, all of which are everywhere in our daily lives. Green Metal Co., Ltd. produces precision processed items for use in medical equipment, such as the metal parts through which endoscope wires are passed.
With our desire to contribute to all areas of social life, we make daily efforts to reach this goal.

[Strengths of our products/technologies]
Machine tools are machines for machining various materials to produce parts, and are sometimes referred to as machine-producing machines. In machine tools, Green Metal Co., Ltd. has been engaging in precision parts machining using automatic boards (automatic lathes) since its foundation. In the first years since our foundation, we mainly produced precision parts for use in major electric-appliance makers’ products, and as we produced almost all of the parts using automatic lathing, our technological skills have been highly praised. Since then, we have increased our number of automatic boards to 150 while incorporating the most advanced technologies of the times. It is rare to see a company that owns this many automatic boards, and precision parts manufactured by Green Metal Co., Ltd., are used in a wide variety of products that are essential to daily life, such as medical equipment, automobiles and smartphones. The maximum size we can accommodate is φ16; however, we are adept at processing small diameters of φ5 or less, with processing accuracy clearing that clears 3 μ specs in some cases.
