Bi-Metal Castings
Similar to the development of selectively-reinforced composite materials, LT has developed process techniques to manufacture lightweight structures with dissimilar metals. Also called “bi-metal,” the structure utilizes one metal in a certain region to serve a particular need, and is surrounded or carried by a lower density metal to deliver a lighter-weight structure.
Loukus Tech uses the squeeze casting process to manufacture a high integrity cast structure that incorporates steel inserts. In addition, LT uses its proprietary thermal barrier technology to coat the inserts to prevent premature solidification and to cast extremely thin walls.
Improving Transportation
The ultimate goal in bi-metal structures is to achieve complete load transfer across a joint, and this requires a high integrity joint. Without a mechanical feature the joint lacks integrity and is unable to transfer load.
To overcome the lack of a metallurgical bond between dissimilar materials, it’s typical to design with interlocking mechanical features that remain within the cast matrix. The downside of this approach is the thick wall around the features minimizing the weight reduction. Lokus Tech's technology and approach enables thin walls without the quality issues that are common typical process methods.
The applications are primarily focused on improving efficiencies in transportation - in automobiles, military vehicles, and aviation. Some applications include cast aluminum frame nodes that incorporate high-strength steel pillars and cast aluminum containing armor steel inserts.
Optimize Performance
Loukus Tech’s work is intended to optimize the performance of bi-metal cast components, developing lightweight structures while minimizing costs associated in manufacturing these joints. Loukus Tech has filed four patents, and developed unique structures and processes including a dual chamber, burst pressure, and tank for vehicle applications.
Loukus is seeking financial and commercial partners to bring resources and investment for future product development, manufacturing scale-up, sales, marketing and distribution.
