Greeting
Through our molding business, we have been engaged in a wide variety of molds, from the ultra-high volume molds of the 1970s to today’s molds for diverse and small-scale production.
Along the way, we have had the opportunity to learn by embracing challenges and responding to various requests from our customers and we are deeply grateful to our employees who have been nurtured by this experience.
A mold is a very important tool (mother tool) for the repeated production of stable products. Based on our 50 years of mold making experience and skills, we will continue to satisfy our customers with our “commitment to never compromise quality” and “courage to abandon stereotypes”.
We are also prepared to handle orders for integrated product development, from design and functional design to mold making and production processes.
We are happy to consult with you on small-lot production, difficult-to-process items, or any other project. We look forward to working with you.
