OEM / ODM


In today’s world of rapid response manufacturing, your existing design can become outdated quickly. QFCM’s product development team is designed to respond to the changing market and can remodel an existing design or work with you to create a new one. Your product development is made easier with QFCM backing your project.

Using computer modeling software, we create an interactive 3-dimensional digital part. This 3D model evolves throughout the product development process, and it allows us to generate the data we need for prototyping and manufacturing your product.


QFCM’s engineers are highly innovative, have decades of experience and can help reduce the problems inherent to manufacturing by utilizing:

  • 3D Modeling

  • Fit, Form, Function

  • Tolerance Analysis

  • Reverse Engineering

  • Cost Reduction

  • Lean Manufacturing Principles

Our product development team is constantly looking for ways to improve your product’s performance and make your design work for you. Our engineers review your project’s parameters and make cost saving recommendations based on the most efficient design.


Our engineering team can help generate new and innovative concepts for your product, and having a variety of concepts to choose from ensures that your design suits you. Our engineers can take your current design and efficiently change the mode of manufacturing to develop a better and stronger product at a competitive price.

We would love to work with you or your engineers to help discuss the best options to help in the design and manufacturing of the new process.
