Custom Injection Molding

Custom injection molding has been our specialty since our company’s inception. Today, Ames Industries maintains two large injection molding facilities, with a combined forty thousand square feet of manufacturing space, equipped with a full complement of high-performance plastic injection molding machines. Using this equipment and our experience in the industry, we process a wide variety of thermoplastic resins, meeting virtually any industry requirement within our press base. Whether your project requires conventional injection molding, overmolding, insert molding, or miniature component molding, we have the practical knowledge and experience to meet your needs.

Our Machine Capabilities

Ames has 37 machines for customized injection molding services ranging between 17 tons and 265 tons for shot sizes between .37 oz and 21.29 oz. Seven presses are fitted with cavity pressure technology, and the majority feature integrated blenders and full 3-axis servo robots for improved loading and unloading. We can also efficiently overmold parts for you, using our technology to decrease loading times and increase production.


Overmolding is not always as easy as it sounds. Different shrink rates, the temperature of the insert, and registering the insert can cause headaches when overmolding. Ames Industries has the expertise necessary to get the job done right, handling any challenges that overmolding may present. Whether it’s steel, another polymer part, electrical connectors, or a threaded insert, Ames has mastered overmolding and serves a wide range of applications with our capabilities.


From commodity plastics to engineered polymers, Ames can process a wide range of thermoplastic materials for our customers. We understand that each material behaves differently during injection molding, and we use our experience with the many different plastics available to tailor troubleshooting and quality control measures accordingly, allowing us to resolve any issues quickly.
