Message from the Company President
Reterra Inc. was founded in 1977 in Tokorozawa, Saitama Prefecture, not far from Tokyo.
Right from the time of our establishment we employed vacuum casting methods, which were not commonly used at the time. This helped us produce castings that have consistently high interior quality.
We were also one of the early users of squeeze casting, a special process giving us an enviable reputation among customers as “Do-it-right Squeeze Casting Reterra.” In 2007, the Ministry of Economy, Trade and Industry listed us among Japan’s 300 most dynamic manufacturers.
We have made our experience in the field a positive force not only for squeeze casting but also for general die-casting, supplying products that exhibit excellent interior quality.
To respond accurately to customer requirements for such high quality products and supply them at a more reasonable cost, we conduct research into the development of special methods and materials, all the while building on our experience.
The motor vehicle industry is our main source of orders. Its growing need for lighter products is encouraging them to consider switching from steel to aluminum components, thereby using more castings. This has resulted in a range of different requirements for casting quality and advanced products.
We will continue to satisfy these customer requirements by applying the technologies and experience we have gained over the years, and by proactively promoting new developments.
We are also shifting to manufacturing our own molds (after many years preparing for this step), and are promoting our business overseas.
Reterra is ready to respond positively to your various aluminum die-casting requirements.
Reterra employees work at our facilities in the Chichibu district, an area of Japan known for its beautiful wooded mountains and valleys.
Here they bolster our efforts to continually improve casting techniques and create products that lead the industry. Their zeal and diligence are a source of strength for the company, and one reason why customers trust us.
When it comes to employee welfare, Reterra’s philosophy is “Respect and honor our workers.”
