Pioneering Automation Solutionssince 1964

Star Seiki Co., Ltd., the parent company of Star Automation, Inc. (SAI), was established in 1964 as a global leader in automatic unloaders for the injection molding industry. More than 60 years of experience have helped Star Automation improve productivity, profitability and workplace safety for injection molders worldwide.

Star Automation, Inc. opened in Menomonee Falls, Wisconsin, in 1991 as a wholly owned subsidiary of Star Seiki. Today, our Wisconsin operation serves as a production and sales hub for North America, delivering advanced automation solutions for an evolving manufacturing industry.

We pioneered the first servo robot for injection molding, establishing a new standard for precision and efficiency. Our commitment to quality and reliability also led to early ISO 9001 compliance, making Star Automation one of the first North American companies in its field to meet the rigorous standard.

With subsidiaries, joint ventures and sales agencies across North America, South America, Europe and Asia, Star Automation serves a truly global market. Our 35,548-square-foot Wisconsin facility features modern processing machinery and testing equipment for precise, dependable production.
