There’ll be a hot new assembly tool on display at the Fakuma show in Germany next month. The Zahoransky Group, which has produced more than 500 multi-component molds, will be showing the first-ever Servo Cavity Positioning System (SCPS), which is a sophisticated way to make a three- or four-color part with one standard injection molding machine without using ancillary systems, such as indexing platens. In a nutshell, it means if you want to design a plastic part with four types of material, the cost just dropped, possibly substantially. You’ll need a good production run, though, because this tool is sure to be pricey.
For starters, the SCPS mold has a control system that is independent of the machine control system. Movements are controlled by precise electric motors. Indexing components rise upward (via spindle) in the moving half of the tool to various injection stations.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
Using simulation to guide the drafting process can speed up the design and production of 3D-printed nanostructures, reduce errors, and even make it possible to scale up the structures. Oak Ridge National Laboratory has developed a model that does this.
