Wm. F. McGraw & Co. offers precision assembly services designed for the most stringent applications in industry. Based in Riverview, MI, with decades of experience in assembling engineered components, we have assembled functional and structural components to meet applications with strict requirements. Our practitioners are both technically knowledgeable, and our facilities are designed for assembly. We offer the ability to manufacture custom part assembly, as well as sub-assembly services, to a complete turnkey assembly service. Mechanical fit up, electrical function, thermal operation, etc, are all existing processes for us, and each will verify performance and functionality of every marketed part.
Our mechanical assembly service centers around dimensional tolerances and long-term performance in every part we manufacture. We can handle high-volume production, prototyping, mechanical assembly, different materials and components, and everything in between. Mechanical assembly services are useful for any project where long-term performance and structural integrity must be repeatable and consistent. Our technicians will always work with your engineering team to ensure appropriate fit, alignment, and function.
We apply different bonding and joining technologies to create strong, durable assemblies that will satisfy our project objectives. These technologies allow us to achieve not only the structural integrity we seek but the performance characteristics we need for the application. Some applicable technologies include:
Our specialized techniques deliver tailored solutions for joining and structural reinforcement. We adapt to the unique demands of each component to ensure performance and precision.
Custom joining techniques tailored to specific requirements: Whether integrating specialty adhesives, unique fasteners, or novel mechanical fixtures, we design joining methods that suit your component geometry and functional demands.
We support OEMs with electrical and thermal assemblies that demand exacting performance. Whether bonding conductive paths or building components to handle heat transfer, we apply proven techniques to enhance product reliability. Our assemblies are built to meet application-specific standards for electrical insulation assembly, EMI shielding, and thermal regulation in power distribution or high-temperature systems
We specialize in assembling electrical components for critical performance demands. Our team brings proven experience in building complex, reliable systems:
We deliver more than just components—we deliver confidence. Clients across industries depend on us for our reliable processes, specialized equipment, and tailored support.

We bring decades of hands-on knowledge in material behavior, bonding science, and design-for-assembly best practices.

Our climate-controlled and precision-equipped workspace supports everything from kitting to final system integration.

Every project aims to meet your product's mechanical, electrical, or environmental performance goals.

We collaborate early and stay involved through prototyping, process refinement, and final delivery.
