Optimizing Large Parts Molding Projects


A successful part starts with a well-designed mold. This complex and precise process determines part manufacturability and lifecycle costs, and takes into account the key components of mold design while adhering to a part’s unique specifications.

Tooling and Mold Building

Design for Manufacturability

This robust process employs strategic preparation and applies strict quality controls to ensure a consistent product output—and a competitive advantage for customers. DFM is the cornerstone for every project EVCO undertakes because the design and engineering process is critical to success.

Design for Manufacturability

Materials Selection

When developing a new part, determining the right material is essential. As part of the DFM process, understanding the requirements and performance characteristics of the part allows EVCO to determine the best material for your project.

Materials Selection


Our commitment to quality is based on stringent guidelines and blends seamlessly with our deep manufacturing knowledge and experience.
