Our Strength

We possess a wide range of processing technologies essential for manufacturing — including laser processing, wire cutting, sheet metal welding, pressing, machining, turning, and polishing.

By combining these capabilities, we can produce high-precision and cost-efficient components.
For multi-process parts, our internal teams coordinate closely on delivery schedules and production procedures to ensure smooth operations, enabling us to meet short lead times that match customer requirements.


Manufacturing Process Overview

Core Technology

 
Our core strengths lie in precision sheet metal processing and micro machining, which are essential for prototype manufacturing.
We are capable of highly complex operations—such as performing 22 consecutive bends within a 10 mm area and producing micro-sized components smaller than a sesame seed.
Our technologies continue to evolve, supporting advanced industries including medical devices, robotics, and R&D sectors.
Precision Sheet Metal

We ensure strict quality control using advanced measuring instruments from Mitutoyo and Keyence, maintaining temperature-controlled environments for micro-part inspections to guarantee accuracy.
By managing every process—from design to machining and inspection—internally, we achieve both high quality and fast delivery, serving a broad range of domestic and international clients.
