 Engineering Success

Our success is determined by our ability to maximize your success – and we know for injection molded plastics, the engineering and design development process is critical to achieving that success!

We have found the two most critical factors for success in the engineering and design development process are partnering with you early on in the design phase – and focusing on what we consider the 5 Keys to Success for engineering out cost and engineering in quality and optimal performance. To achieve success, all five of these stages must work together.

a. Part Design and Material Selection – Understanding the product application, intended market and performance, end use objectives, and use environment
b. Tool Design and Mold Building – Design for mold efficiency, longevity and performance
c. Molding Process – Injection molding technologies, cycle times, material flow and employing scientific injection molding
d. Quality Systems and Metrology – Focusing on tolerances, part inspection, steel safe mold and more
e. Automation Systems – In the injection molding process and downstream – making it simple and lean





Our experience, along with the latest innovations in custom plastic injection molding technologies, has provided us with a competitive advantage on each and every project.
