basic information
**Business Description** [Manufacturing and Processing of Plastic Products] ○ Primarily engaged in injection molding, handling a wide range of products from precision parts to exterior items, insert molding, transparent resin molding, elastomer resin molding, and gear molded products. ○ Capable of responding to customer requests from a single prototype to mass production. ○ Also able to accommodate resin conversion from metals and provide value-added proposals. [Die Design and Manufacturing] ○ We create molds that satisfy customers by conducting detailed discussions with them, considering not only shape and dimensions but also moldability during mass production, mold durability, and cost performance. ○ Utilizing the latest equipment, reliable technology, and experience, we manufacture molds from prototype molds to mass production molds with innovative ideas. ○ We can also handle mold manufacturing only. [Assembly (Sub-Assembly), Secondary Processing, Humidity Control (Annealing Treatment)] ○ In addition to molded products, we procure other components such as die-cast parts, springs, general screws, custom screws, seals, and rubber from partner factories, delivering them as assembly unit products. ○ Humidity control (annealing treatment) of nylon resin and others is performed using a steam-type annealing tank, allowing for uniform humidity control in large quantities at once. ● For more details, please contact us or download the catalog.
