Yoshiwa's strengths 02 Advanced Casting Technology
Our expertise allows us to produce parts that are difficult to manufacture.
We constantly improve our casting methods for high precision and cost performance.
We can meet high-mix, low-volume demands and special shapes.
Yoshiwa's strengths 03 High Quality and Cost Efficiency
We balance high quality with low cost.
By improving production efficiency and eliminating waste, we provide competitive products.
We also work with customers to propose optimal designs and solutions.
Yoshiwa's strengths 04 Creating the Future of Casting with IoT
Casting factories are often seen as "3K" in Japan (tough, dirty, dangerous).
We are developing:
A new process to reduce dust and waste using less sand, in collaboration with universities.
IoT-based automation and monitoring systems (e.g., using Arduino for furnace error detection).
Young employees lead this innovation, supported by a well-equipped test lab.
