Since 1953, Sengoku has continued to grow its technological and production capabilities,expanding its field of business while accepting manufacturing contracts from a wide range of companies including major Japanese manufacturers.
Utilizing the abundance of know-how and experience we have cultivated through this history, our flexible and precise manufacturing capabilities support the diverse needs of the changing times.

We cannot meet the wide-ranging needs of the customer if we do not always strive to further refine our technology and achieve better manufacturing.
Not only do we realize the customer's ideal form,we work as a team with the customer to consider ways to make the item even better.

Rather than simply carry out work according to the customer's demands, we offer solutions while making considerations for parts and manufacturing methods that control for cost.
With this high degree of flexibility, we work to come up with a unique approach while capturing the essence of each project.
We provide customers with manufacturing that has further added value,not simply handling orders for streamlined efficiency, but offering support capabilities and solutions that are unique to Sengoku.

Sengoku is always striving to meet the wide-ranging needs of the customer.
This has led to countless new ideas and technologies created through the design and development process. every year we apply for new patents and utility models.
We thoroughly handle customer manufacturing, coming up with solutions to realize the ideal form.

We look at function, quality, cost, usability, design, and other factors through the lens of the manufacturer and customer, then use our knowledge, experience, and technology as experts in manufacturing to provide added value unique to Sengoku.

Sengoku's patented technology led to the creation of the graphite heater, a true innovation in the heating world.
The graphite heater is able to efficiently deliver heat without wasting energy, with heat delivered in an astoundingly swift 0.2 seconds reaching a maximum temperature of 1,300℃.
Combined with the design's high degree of versatility, graphite heaters have great potential to lead to the development of new products never seen before.
Sengoku is focusing on developing new high value-added products that take advantage of this patented technology.

During the prototype stage of design, we conduct various simulations,and calculate product performance and functionality by analyzing heat conduction, fluid mechanics, and strength.
This upstream analysis of the manufacturing process helps to achieve an even more ideal form,further improving quality, reducing cost, and shortening delivery time.

We use 3D printers to confirm design and shape during prototyping.
3D printing allows project members to share the modeled image and identify issues early on,whereas prior these issues had to be confirmed using two-dimensional images.
This allows us to carry out low-cost, speedy prototyping.

From the design stage, we come up with designs that meet both Japanese standards and overseas certification criteria.
Our broad perspective contributes to customer profits by increasing the potential of future sales channels and helping to swiftly achieve overseas expansion.

We determine the optimal production factory among our manufacturing bases in Japan, China, and the Philippines (all in-house factories)based on the customer's product and demands,resulting in a system that offers high quality and quick delivery.

We are working to automate and roboticize our production sites with the aim of improving productivity and contributing to industrial development.
Automating strenuous and simple tasks also fosters an environment where employees can work with a sustained purpose and have more time for creative tasks.
