Integrity Manufacturing brings over 50 years of experience to the metal working industry. Our leadership team, Cheryl, Holly and Sean, were employees at Lindy Manufacturing. In 2017, they joined forces to complete a limited asset purchase of that company, to build a new organization that would be a leading provider of quality metal stamping, finishing and assembly work for a wide array of industries.
Now, as one of the few women-owned metal stamping companies in the US, we have expanded our production capabilities with additional equipment and three new locations – two in the Chicago area and one in the Los Angeles area.
We specialize in American-made, precision metal stamping and complex assemblies for companies around the world.  But unlike many other companies in our industry, we provide turnkey service by managing projects from beginning to end – including tooling, material sourcing, stamping, finishing, assembly, packaging and global shipping. Our clients depend on us to handle the details, big and little, to ensure their products arrive on spec, on time, and on budget…every time.
