Given the years of experience and an established track record of development in pressed terminals for connectors, WADA INDUSTRIES is capable of providing an option for bulk production of stamping dies during the development review stage.
For products large in demand, we strive to be practical as well as cost-effective, which includes increasing SPM and the number of rows and cavities, as well as proposing methods for multiple products arrangement in a single pitch.
Due to our experience in contract manufacturing the stamping parts of board-to-board connectors and FPC connectors for numerous connector manufacturers, we are always focused on improving the mass production capabilities of our die manufacturing, and are always working to refine our die manufacturing technology to support narrow pitch and high speed manufacturing needs.
Stamping die maintenance and inspection is needed to ensure a consistent supply to fulfill customer needs. In order to improve the durability of the dies, our top priority is to consider measures to counter wear, which includes coating main die-parts, and selecting die-part materials tailored for the stamping material.
WADA INDUSTRIES is distinguished by its consideration for mass production.
We are always refining stamping technologies and proactively working to introduce new stamping methods in order to help the customer. This includes "post-cut", "precise bending", "shaving-cut", and so forth.
Dependent on product difficulty and order conditions, WADA INDUSTRIES is able to provide samples of mass production dies within approximately six weeks.
One of our strengths is that, when starting die manufacturing, our die designer works with the customer on its creation, which allows us to produce a die design that meets their specific and detailed demands.

In addition, we have a proven track record of joint development with the customer, and are capable of providing support from the initial design stage.
Whether dealing with die-parts change, stamping trial of dies, or unexpected damage to die-parts, we respond quickly. This is a crucial factor, as it shortens not only stamping trial of dies but also MTTR during mass production.
WADA INDUSTRIES is equipped with a variety of machining tools in-house to provide rapid response.
In addition to die parts, we also manufacture punch shoe, die shoe, and die plates in-house.
While in some cases, we may be unable to process all parts in-house, we have a die parts procurement network in the Tohoku region and also procure parts from overseas, resulting in a supply system that gives our customers peace of mind.
Die size increases for complex or long-pitched stamping parts. Conventional W-EDM can support lengths up to 450 mm per one die plate. When this size is exceeded, a second plate is necessary. Separating into two plates creates issues such as a decrease in precision and an increase in die-parts numbers and so on.
WADA INDUSTRIES retains W-EDM that is equipped with a bed size that can support lengths up to 600 mm, making it possible to process the die plate as a single die plate.
Iwate Prefecture is located in the north-east Japan (=Tohoku region). Tohoku region is the one that specializes in precision die-parts manufacturing and has the Research Center for Die and Mold Technology of Iwate University, and the Iwate Industrial Research Institute, and so on.
