Parts Seiko News [August 2025 Issue]

  • COMPANY

Now, in the previous session, we introduced our polishing equipment, but our company is also focusing on providing added value through technologies related to processing. This time, we would like to introduce our initiatives regarding "welding support." "Do you have any concerns about welding?" - The division of processes is taking too much time. - We can't find a supplier that can handle everything at once. With just one drawing, we can provide a one-stop service from welding to inspection. By consolidating processes, we can improve both delivery times and quality. ● Areas with proven delivery records Parts for semiconductor manufacturing equipment / Parts for food machinery / Parts for machine tools, and more. ● You can also trust us with leak checks after welding! We can handle parts that require high reliability with the following inspection methods: - Pressurized holding method - Underwater method - Soap water application method - Penetrant testing - Helium leak testing Please consult with us first! We will work alongside you to propose the optimal solution for your challenges.

Parts Seiko News [July 2025 Edition]

  • COMPANY

Now, in the previous session, we introduced our robotic equipment, but our company is also focusing on providing added value through technologies related to processing. This time, as part of that effort, we would like to introduce our initiatives regarding the "grinding machine." In addition to high-precision capabilities in cutting processing, we have introduced cylindrical grinding machines to meet stricter quality requirements. As a result, we achieve a consistent response from processing to grinding using in-house equipment, providing high value in terms of both precision and efficiency. ~Do you have any of these concerns?~ - Looking for a manufacturer that can handle both cutting and grinding processes - Searching for a manufacturer that can perform grinding on high-precision parts - Wanting a single contractor for multi-process grinding such as flat grinding and internal/external grinding With our integrated system, we will solve challenges related to "delivery time," "precision," and "cost." For products that require quality confirmation, we can handle everything in-house from the prototype stage to mass production. We will also actively take on projects that other companies find difficult to handle.

Parts Seiko News [June 2025 Issue]

  • COMPANY

This month, we would like to introduce our "robot equipment." Our company is also focusing on automation using robots developed by our own technology department. As the first step, we have introduced a robot system to the MC machining center at our headquarters factory in Saitama. This robot equipment is equipped with a vice changer, which eliminates unstable factors in workpiece attachment, enabling consistently high-precision and stable machining. This technology has improved the uniformity and quality of processes that previously relied on manual labor, allowing us to provide our customers with more reliable products. Additionally, the process that used to take 2.5 months has been shortened to 1.5 months, contributing to improved delivery capabilities. As a result, we can ensure smooth deliveries even for tight schedule projects, achieving both increased production efficiency and enhanced customer satisfaction. Moving forward, we will continue to pursue technological improvements, stable supply of high-quality products, rapid response, and cost optimization, providing solutions that best meet our customers' needs. If you have any inquiries regarding projects, please feel free to reach out to us.
