Pre-Production Activities

We take ample time to conduct thorough preparations prior to production so as not to face any issues once production starts. We minutely prepare everything associated to production, including arranging molds, jigs and parts, and also validate the efficiency of actual production.

At our plants, we utilize facilities such as our thermal shock testing equipment, and combined climatic and dynamic testing equipment, and conduct rigorous reliability evaluations and quality management of our products in order to prevent any malfunctions.

In addition, we build an optimal supply chain that extends from procuring parts to delivering products to our customers, and thereby reduce production lead time to the fullest extent.

  • Parts are placed at where they can easily be accessed to improve productivity

  • A standard finished product is placed at where to double check the quality of other products


We produce our products at our worldwide production sites. We consistently strive to make improvements with quality and efficiency in mind at all times.

When assembling parts on our assembly line, we utilize jigs to prevent any mistakes, thereby ensuring meticulous production that is free of quality issues.

We then conduct a final quality inspection before shipping and finally deliver our products using packaging which takes into account the condition of transport to customers' production sites.
