SINTX TECHNOLOGIES AWARDED PHASE I CONTRACT FROM THE MISSILE DEFENSE AGENCY FOR ELECTROCHEMICAL MACHINING

SINTX Technologies, Inc. (www.sintx.com) (NASDAQ: SINT) (“SINTX” or the “Company”), an original equipment manufacturer of advanced ceramics, announced today that is has received a Phase I contract for $150K from the U.S. Missile Defense Agency (MDA; https://www.mda.mil/) to enhance the performance of electrochemical machining (ECM) of critical components for aerospace. The project calls for SINTX to develop and demonstrate the unique advantages of corrosion resistant, dielectric, insulating multilayer coatings that will ultimately enable unprecedented tool life and exceptional ECM machining performance. Corrosion-resistant insulated coated tools made by ECM aim to lower costs and improve the quality of precision-machined aerospace, automotive, medical, computer, and consumer electronic components, thereby providing significant opportunities for market growth. ECM is an iterative process and is presently the most expensive element in advanced tool development. Dielectric insulating coatings that extend tool life could therefore generate significant cost advantages.

The proposal was originally submitted by Technology Assessment and Transfer (TA&T), which is now a wholly-owned subsidiary of SINTX. In the Phase I MDA contract, SINTX will develop thin-sputtered alternating multilayers to produce dense, pinhole-free coatings with lower residual stress and reduced thermal conductivity, when compared to single-layer coatings. The multilayer coatings will be deposited onto a stainless-steel substrate. A partner, Voxel Innovations (VOXEL; https://www.voxelinnovations.com/), will evaluate the corrosion and durability performance of the coatings developed by SINTX. After successful completion of the Phase I effort, SINTX intends to pursue a Phase II contract, aimed at scaling up the technology toward prototype development and technology demonstration.

“SINTX Technologies Inc., through its subsidiary TA&T, has been developing high-temperature, multilayer coatings for metals, ceramic matrix composites (CMC’s) and other high-temperature materials for over 30 years,” said Dr. Sonny Bal, President and CEO, SINTX Technologies. “We believe that this concept has strong merit, and that the MDA contract will allow SINTX to move the technology towards scale-up and commercialization.”

The global micromachining market in the U.S reached $2.5 B in 2019, and is expected to grow further (see: https://www.grandviewresearch.com/industry-analysis/micromachining-market). Increasing demand for precise machining of micro-components in automotive, aerospace, healthcare, and consumer electronics is driving market growth in three categories, namely, traditional, nontraditional and hybrid. Of these, the non-traditional category accounts for over 50% of sales because of the increasing demand for technologies like electro-discharge machining (EDM), electrochemical machining (ECM), and laser machining; this is the segment targeted by SINTX in the MDA contract. The turbine engine market, as an example, is expected to approach $1 trillion by 2031, that growth is facilitating ECM-based development of hard-to-machine titanium- and nickel-based superalloys.
