Post-Mold Services

At Stelray, we offer a range of post-molding value-added services for our customers that require more than just a molded part. Pad-printing, hot stamping, painting, plating and shielding services are available for decorating and coating requirements.

If your program requires packaging or assembly, we offer bagging options to complete full-service packaging services.

Engineering & 3D Prototypes

At Stelray, we are often asked to assist in the plastic part design development and prototyping of new product ideas for our customers. If “speed to market” is your concern, Stelray’s in-house 3D printing services can be the solution, or consider the development of a quick turn soft tool constructed in our in-house tool room. As a full-service plastic injection molding company, we offer a number of product design and engineering services to help develop form, fit and function of your part for successful plastic injection molding.
