About Our Company

Rapid prototype and short run plastic injection molding

4 axis aerospace machining, fixturing, secondaries


Design And Engineering 

We can assist in designing your parts for injection molding. Our experience in plastic part design can help you avoid problems in the area of cosmetics, functionality, fit and material selection. We accept almost all files, and are currently using 1 seat of CIMATRON, 2 seats of SOLIDWORKS, and 3 seats of SURFCAM. The Toolmakers on the floor as well as the molding Techs have access to all of the Assembly files to assure a streamlined approach to the job from start to finish. This assures that all parties involved are on the same page throughout the projects lifecycle.

Molding Department

In our Connecticut facility, we provide production and short-run injection molding and other prototype services such as SLA and 3D printing.


Tooling Department

Our in house tooling department is one of many things that sets us apart from other injection molding companies. From inspiration, to creation until completion, we are able to maintain a hands on approach through the whole project. By keeping this part of the process in house our machinists have a full understanding of what is needed to get the job done. 

Secondary Operations

Our assembly department is skilled in performing all secondary operations to your products.
