Moveable nozzle and two-chamber structure are the secret behind Komachi’s strong drying performance

Eliminates need to blow after washing

●Moveable drying nozzle
Strong drying performance with a patent-pending washing system.

The moveable drying nozzle allows workpieces to be blown at even closer positions. Experience a drying performance that is unthinkable in a water system.

●Double-chamber system
The double-chamber system, which separates the washing and drying chambers, is a mechanism that prevents moisture from entering the drying chamber and supports the product’s strong drying performance.

Countermeasures against water stain by water droplets trickling down from the top of the chamber are “watertight”.Why not discontinue the process of blowing after washing with the use of "Komachi"?

Precision metal machining technology for over 20 industry categories

Contracted production of parts that are highly difficult to process and require a high level of quality control

●High-quality assurance
The idea that medium-sized parts that are highly difficult to process and require a high level of quality control (about 50 to 500 parts) must be manufactured in-house is out of step with the times.

Nakano Manufacturing delivers distinctive parts in medium-volume lots, which had traditionally been considered as only being able to be produced in-house,to its customers after quality has been assured at Nakano Manufacturing.

●Increased output
Nakano Manufacturing has established methods to efficiently produce complex processed parts with stable quality, beginning with scratch-resistant materials, including sealing surfaces and valves, such as semiconductor manufacturing equipment.

Nakano Manufacturing will help increase production output through thorough production and quality assurance systems as a means of responding to its customers’ needs.
