Advantages of Daido’s injection molding

Injection molding is a process for obtaining a product by injecting a molten material into a mold, and cooling and solidifying it. The process is suitable for mass-producing products in a variety of shapes from simple to complex. We have 14 injection molding machines capable of clamping forces from 80 tons to 350 tons, and offer products in a wide range of fields including the automotive, office appliance, construction and environmental fields.
We are the first company in the automotive industry of Japan to manufacture airbag covers with a single injection system, and excel in molding elastomer parts.

A long-standing injection molding company

We have been engaged in the molding business since October 1947. This means that we started molding products just a few years after injection molding machines had been introduced into Japan. We offer a variety of molding services by utilizing the know-how accumulated over the years.

The first company in Japan to manufacture airbag covers

Ahead of all others in the industry, we started manufacturing airbag covers with a single injection system in January 1990, and have ever since offered products that meet the quality and reliability requirements of automotive components.

Working on various ejection techniques

We use a variety of ways to eject parts with undercuts that are difficult to mold and release because of the mold structure, and promote automation by drawing on our experience and expertise.

Thorough mold management

Molds are an indispensable tool for injection molding. We keep a record of the number of shots performed with your molds and have our own mold experts perform regular maintenance. We carefully maintain your molds so that they can be used for molding in the best condition at any time.
