Putting Medical Injection Molding Projects in Motion

Different processes offer different advantages. Here are the ways we can optimize your medical part projects.

Multi-Shot Molding

Create a strongly bonded, integrated part by molding material around an insert piece for enhanced component reliability.

Insert Molding

Produce parts with vibrant, long-lasting color without painting, and eliminate quality issues due to scratching or peeling.

Secondary Operations

Provide fully decorated and assembled injection molded parts and sub-assemblies through value-added processes.

Stack Molds

Increase the output of an injection molding machine using multiple parting lines capable of producing multi-cavities or a family of parts in one cycle.

Optimizing Medical Injection Molding Projects and Parts


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.

Case Study

Preparation Leads to a Better End Product

Developing a new product involves many moving parts, including multiple teams and checkpoints along the way to ensure a flawless end product. Preparation is a vital part of the product development process, as it sets up the rest of the project for success.
