Liquidmetal Outperforms MIM and DieCast
Liquidmetal Technologies Inc. is a contract manufacturer that uses a patented injection molding process to produce amorphous metal components. Amorphous metals are a class of alloys developed to maintain an amorphous atomic structure in a solid state. This allows you to mold precision parts without shrinkage and achieve great mechanical properties.

Why Use Liquidmetal?
Strength, hardness, elasticity, and corrosion resistance are achieved directly out of the mold without secondary processes. This technology can be used in a variety of markets, typically making parts that fit in the palm of your hand.
Reduce Cost $ over CNC Machining
Time is money, and when it comes to producing a part, injection molding is the cost saving solution. With Liquidmetal, there is finally a metal molding technology with a precision that rivals CNC machining, without the associated costs and material scrap.
CNC machining offers a quick start-up time and ability to make a small quantity of parts with minimal investment. Although convenient, a complex part could take hours to machine and require you to re-fixture multiple times.
Once in production, making several thousand to millions of parts a year, machining is no longer practical. A Liquidmetal part molds in under 2 minutes, reduces cost, and improves part to part repeatability.
How Liquidmetal Parts are Made
Liquidmetal is a Zirconium alloy that was designed specifically for injection molding. Unlike other high-strength alloys, Liquidmetal melts at a low temperature which allows it to be molded within our machines.
Other molding processes for high-strength alloys require complicated systems of combining and removing polymer powders from the substrate or creating single-use sand casted molds for each part.
What are the Material Properties?
The amorphous structure of Liquidmetal not only gives it incredible strength but it reaches ultimate strength without any plastic deformation.
Most alloys require a heat-treating process to achieve a usable hardness. Liquidmetal is naturally hard and cannot be heat-treated any further.
Normally when a material is very strong and hard it is also very rigid and brittle. The amorphous atomic structure of Liquidmetal opposes this phenomenon and has the elasticity of a spring steel.
Liquidmetal has 85-90% the density of Stainless Steel. Along with reducing wall sections with the higher strength material, there are opportunities for significant weight reduction.
How else is Liquidmetal unique?
The amorphous atomic structure of Liquidmetal makes it non-magnetic, and it cannot be magnetized.
The lack of grain boundaries gives Liquidmetal an efficient transmission of acoustic wave energy uniform across a wide band of frequencies. Liquidmetal can increase audible decibels, sustain, and timbre.
Liquidmetal molds with minimum shrinkage so the parts achieve the precision of CNC machining. It can also mold flat parts within microns without warping.
