In the present research project, the IKV team is examining the possibilities for producing lightweight parts with a thermoset matrix. Similar to the already known process involving the integrated molding and back-injection of thermoplastic FRP, the aim is thus to combine the favorable lightweight properties with the greater part complexity that is possible with injection molding, and apply this to thermoset parts, too. Two innovative process routes are used: a two-step process route involving the backmolding of parts previously produced in the established RTM process, and a single-step route involving the backmolding of towpreg/prepreg materials, which, integrated into the process, cure in the injection molding process. Both methods have the advantage of a reduced number of production steps compared with conventional functionalization strategies such as bonding or riveting, and of shorter cycle times.

The Liquidmetal alloys are available in the form of slugs cut from round rods. These blanks are automatically fed into a chamber, where the material is melted inductively under high vacuum conditions. Very rapid cooling with exclusion of oxygen leads to forming of the amorphous structure. Standard robots, such as the Engel viper series, are used to remove the finished parts. The sprue can be removed with the help of a water-jet cutting machine or mechanical shears.

During the technical presentations, Gerhard Dimmler, Engel’s senior vice president of R&D, addressed just why the company got involved in this new technology: “The processing is very close to the injection molding process—it’s a useful complement to our core technologies,” he says. Additionally, it provides the company with additional market access.

With Liquidmetal, Engel is presenting an alternative to metal injection molding (MIM) and CNC machining. Unlike those other processes, the machine can produce Liquidmetal parts in 2-3 min. In addition, there is no waste accumulated in Liquidmetal processing because the sprues can be recycled.   POTENTIAL APPLICATIONS  During the symposium, Engel molded parts for medical forceps with Liquidmetal alloy. The company says it chose to showcase that product because it sees good potential for Liquidmetal technology in the field of medical technology. For instance, endoprostheses like hip joints or stents are also possible with Liquidmetal. Engel also foresees it being used in electronics, aerospace, military technology, and sports equipment.

NEW INJECTION MOLDING MACHINE  Still, processing Liquidmetal alloys is not an easy endeavor—particularly because in the molten state it is highly reactive to oxygen. For this reason, Liquidmetal alloys must be processed quickly and under a highly controlled vacuum. With that in mind, Engel developed a new injection molding machine based on its all-electric machine series, the Engel e-motion. The company says that the difference between a Liquidmetal machine and a conventional injection press lies mainly in the injection unit. Instead of a screw, the machine relies on a piston that injects the molten metal alloy into a thermo-regulated mold.

The mounting demand for plastic parts reinforced with continuous fibers is based on their high mechanical strength with up to 25% less weight compared with metal parts. For this reason, their production and in particular the economic benefits of the process and the reduction of production steps with short cycle times have been the subject of various research projects. Whereas FRP parts with a thermoplastic matrix are already being produced on an industrial scale and are in widespread use, IKV is now occupied for the first time with the production of continuous fibre-reinforced lightweight parts with a thermoset matrix. Because of their better low-temperature resistance and higher mechanical and thermal load resistance, thermosets are superior to thermoplastics in many applications.

Liquidmetal is a class of zirconium alloys that feature an amorphous, non-crystalline structure, which is why they are referred to as metallic glasses. Components made from these materials are extremely hard, but at the same time very elastic, which leads to very good recovery behavior. For example, the elasticity of steel is 0.2% and is 1% for titanium, while the value for components made of Liquidmetal alloys is 2%. In addition, the materials are characterized by their low specific weight and excellent corrosion resistance. This range of characteristics predetermines the alloys for use in precision components that are subjected to high mechanical stresses.

Liquidmetal has a license with Apple, Cupertino, Calif.,  news that generated a lot of attention for the material.
