Led by CEO + Visionary Patricia Miller, M4 has 45 years of custom plastic manufacturing experience. Find out how we can build your dream today.

As I write this, M4 is going in to its 44th year. The company was founded by a toolmaker with an entrepreneurial spirit and a strong desire to live the American dream. Filled with drive and good fortune, my grandfather designed and launched his own proprietary products, as well as partnered with others to bring theirs to market.

In no event shall M4 or its suppliers be liable for any damages (including, without limitation, damages for loss of data or profit, or due to business interruption) arising out of the use or inability to use the materials on M4's website, even if M4 or a M4 authorized representative has been notified orally or in writing of the possibility of such damage. Because some jurisdictions do not allow limitations on implied warranties, or limitations of liability for consequential or incidental damages, these limitations may not apply to you.

M4 is a design and manufacturing house, blurring lines and breaking down silos from concept to final production. With a team that embodies an eclectic mix of technical expertise, keen insights and real-world experience—creators, makers, engineers, designers and strategists work together, across industry and category segments, to make meaningful products that matter.

We take a holistic approach to manufacturing. Our team provides high-touch collaboration across all phases, from product development and material selection, to tool drawings and tool building, to full scale manufacturing.
