グローウィル Company Overview

Kowa Electronic Industries Co., Ltd. changed its name to "Growill Co., Ltd." as of April 1, 2015.

Winding by hand has issues such as incorrect number of turns, variations in quality due to uneven tension, and wire breakage, making it difficult to pursue miniaturization (thinner wires). Labor costs have also become a bottleneck for cost reduction. Our company automates the production of all custom specifications of transformers, including power transformers, SW transformers, DC/DC transformers, and pulse transformers, in Japan (Niigata Prefecture). This automated production allows us to offer stable quality at lower prices compared to hand winding in overseas production. ■ This is an introduction video of Kowa Electronic Industry's factory that has achieved low-cost, high-quality transformers. ■ An automated production line that enables miniaturization with thinner wires. ■ You can watch videos of the production processes of automated production lines tailored to lot sizes and circuit types, including "large lot production lines," "small lot compatible automatic machines," "automatic machines for SW transformers," and "other automatic machines." We will distribute materials to those who request them through the contact form below. Please feel free to reach out to us.

We have started handling chip fuses that are optimal for overcurrent protection devices in small machinery.
