D4E Inc. is the sole North American sales center of Sunwill Mold Branch.
Polyurethane (PU) Casting
PU casting is a tricky process, and is difficult for many other companies to handle. After eight years of exploration, innovation and discovery, we have developed our very own techniques.
Design for
Manufacturability (DFM)
Our team combines creativity with problem solving and engineering skills to meet complex tooling and design challenges.
Our machine shop uses Computer Numerical Control (CNC) machining and Electrical Discharge Machining (EDM) to produce consistent high-quality parts.

D4E Inc. is founded in 2007.

We have been providing high-end prototyping, mold-making, and mechanical engineering services to our clients across Ontario.

We fabricate high-end prototypes with mechanical strength and match surface finishes of mass-produced ones. These parts are not only for working prototypes, but also for low-volume production. Their surface finish is achieved by our abundant post-processing capabilities.

Our expertise in manufacturing and engineering is complimented by our wealth of experience in project management. Our team’s varied skillsets allow us to offer our clients the full spectrum of services from start to finish, including concepts, prototyping, and final product development. D4E’s advanced engineering analytics (for example, finite element analysis) guarantee that we will succeed in meeting any challenge posed by even the most complex designs. We have assisted many high-tech incubators in Canada, such as Cognitive Systems Corp., Baanto International, and Thalmic Laboratories.

We maintain a high standard of control on quality, pricing, and lead time.

We are happy to receive manufacturing jobs of all quantities, from a single piece to millions. We provide our clients with options of various break-even quantities. Often, different quantities determine different manufacturing methods and materials.
