IntriPlex Technologies, Inc., a wholly-owned subsidiary of MMI, is a premier U.S. supplier of structural and mechanical components for battery cells. Specializing in high-volume precision metal stamping and assembly technology, IntriPlex offers a reliable U.S. alternative for battery makers seeking high-quality components such as top lid assemblies and other critical parts in a market often dominated by overseas manufacturers.
“Our goal is to provide battery manufacturers with locally sourced, high-quality components, reducing their dependence on overseas suppliers while boosting operational efficiency,” says David Dexter, President and CEO of IntriPlex.
As one of the first independent U.S. manufacturers of lithium-ion battery lid assemblies, IntriPlex is setting a new standard in the domestic battery market. Combining high-volume stamping technology with meticulous quality and performance optimization, the company is poised to lead the ransformation of battery manufacturing. This independence, supported by MMI’s global infrastructure, allows IntriPlex to adapt quickly and customize solutions for clients, offering a unique advantage.
Meeting the Demand for EVs and Energy Storage
Amid the rising global demand for electric vehicles and energy storage systems, manufacturers are establishing battery cell factories worldwide, creating a pressing need for reliable local suppliers. With two primary manufacturing sites in Santa Barbara, California, and Ayutthaya, Thailand, IntriPlex is well-positioned to meet this need.
At its Santa Barbara facility, where innovation and research take center stage, IntriPlex is pioneering U.S.- based lid assembly capabilities. Known for many industry firsts, IntriPlex continuously pushes the boundaries of manufacturing precision and cost efficiency. The company’s advanced proprietary stamping process offers a scalable solution for intricate parts designed specifically for the battery industry. This commitment to technological advancement is driving breakthroughs in battery component production that are currently unavailable in the U.S.
Precision and Innovation at Scale
IntriPlex’s commitment to excellence is exemplified by its ability to maintain dimensional tolerances down to ±3 microns, even over billions of parts produced annually. These precision capabilities allow IntriPlex to deliver superior performance and reliability to its global battery customers. This is further supported by the company’s investment in advanced technologies and facilities across North America and Southeast Asia.
In its state-of-the-art Innovation Center in Santa Barbara, IntriPlex replicates real-world conditions to test the limits of component capabilities. A notable example is its use of laser interferometry, widely used in the highest-precision fields, to measure the flatness of parts at a micron level. IntriPlex also employs a scanning electron microscope (SEM) to inspect surface conditions and microscopic features, ensuring unmatched precision and quality control.
Powering the Future of Battery Manufacturing
To meet the evolving needs of the battery industry, IntriPlex continues to invest in new technologies and infrastructure. In 2025, the company is looking to expand to the Eastern U.S. to support battery customers in the region, enhancing its ability to meet the growing demand for U.S. -made battery components.
IntriPlex’s ability to scale production and rapidly adapt to new industry requirements ensures that it remains a critical partner for battery manufacturers requiring precision-engineered components.
With global demand for batteries surging, IntriPlex provides a high-quality, U.S.-based alternative to overseas suppliers, rooted in precision and innovation. The company is committed to expanding domestic production and powering the future of battery manufacturing.
