John Kang WebMD | Liquidmetal Processing
John Kang WebMD-Medical Manager Corporation merger in the year 2000, which was worth $20 Billion and considered the most important business deal in the physician space at the time, is advancing a new technological gem with his acquisition and over 10 years of research and development in amorphous metals.
Liquidmorphium is a patented metal alloy made from zirconium, copper, aluminum, nickel, and silver, being developed by Liquidmetal Technologies Inc. for commercial manufacturing and use.
The alloy, John Kang WebMD states, is extremely resistant to corrosion and wear for daily use, has increased shock absorption, and is an “unbend-able” metal that’s stronger than titanium. However, the real potential lies in its manufacturing process.
Here’s how it’s done:
- Material Loading – Liquidmorphium is produced in rods and cut down into what the industry refers to as ingots, or little capsule-like cylindrical sections that can be inserted into a custom-fitted Liquidmetal die-casting machine. Each ingot can be about 200 grams, resulting in a 180-gram final product once all is said and done.
Melting – Liquidmorphium melts at 1000 degrees Celsius. It is heated for one to two minutes using an induction heating system to convert the solid metal into its viscous liquid state.
- Injecting – Once liquid, the metal alloy is injected into a prefabricated mold that can be shaped like anything from the core of a golf ball to an intricate cellphone antenna part.</li
- Cooling – In the past, amorphous metals could only result from tens of millions of degrees of cooling per second in a process called splat quenching, which could only result in wire material. With the Liqimorphium alloy, the near-final product is cooled in moments depending on the intricacy of the resulting part tree.
- Gate and Runner Removal – A part tree is the shape produced by the mold, which has runners and gates (long and thin pieces of connecting material) that hold the actual parts in place once the mold has cooled. The part tree systems, according to John Kang WedMD, also allow for more parts to be formed from a single injection process. Once the part tree has cooled, the gates and runners can be removed. Liquidmetal Technologies uses a high-powered precision water jet to remove gates and runners. As opposed to a laser, water jets do not leave burn marks.
- Machining – CNC machining is used to remove any excess material left over from the gates and runners. On occasions where molds cannot reach the precision or tolerance needed by the product, machining can also be used to apply final touches.
Amorphous metals like Liquidmetal can be processed in a viscous form, much like plastics. In other words, they are molded from a liquid state rather than being pneumatically cut, punched, bent, and then ground down to their final form. Processing amorphous metals cuts most of these processes out and comes up with a near-final product in minutes.
