Using molds to shape things is as old as humanity. In the Bronze Age, the copper-tin alloy was melted and cast into weapons in ceramic molds. Today, injection and extrusion molding shape hot liquids ...

Unlike conventional nickel molds that require coatings or release agents, the new mold integrates lubricating nanoparticles directly into the matrix. Tested across thousands of micro-injection molding ...

Manufacturers that must demonstrate energy savings in their operations can do so by substituting polymer mineral castings for steel structures. The total casting production process is can save up to ...

Composites of continuous carbon fibers and thermoset polymers can now be made using a new 3D printing technology. Such composites are strong and lightweight and may find applications in many ...
