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.
At this year's MD&M West show, lots of material suppliers are talking about new formulations for wearables and things that stick to the skin, whether it's adhesives, wound dressings, skin patches and other drug delivery devices, or medical electronics.
Researchers at Lawrence Livermore National Laboratory have published two physics-based models for the selective laser melting (SLM) metals additive manufacturing process, so engineers can understand how it works at the powder and scales, and develop better parts with less trial and error.
Materials and assembly methods on exhibit at next week's MD&M West and other co-located shows will include some materials you should see, as well as several new and improved processes. Here's a sampling of what you can expect.
The Food & Drug Administration has approved a 3D-printed, titanium, cranial/craniofacial patient-specific plate implant for use in the US. The implant is 3D printed using Arcam's electron beam melting (EBM) process.
