Unique Extruder Reclaims Nylon 11 Oil Pipe
A British recycling company has found an interesting application for the MRS Extrusion System from Gneuss (U.S. office in Matthews, N.C.). K2 Polymers Ltd. in Loughborough, U.K., which specializes in recycling engineering resins, is using the MRS (Multi Rotation System) to reprocess nylon 11 regrind heavily contaminated with oil.The regrind came from deep-sea oil pipes that were scrapped after having been recovered from the sea floor at a depleted oilfield.
How to Select a Plastics Assembly Process
To make the proper choice, each application must be considered on its own. Each has its own particular characteristics and requirements.
More Gloss, Fewer Weld Lines With Variothermal Molding
A higher mold surface temperature during filling is required to achieve high-gloss surfaces or perfectly replicated microstructures and nanostructures, as well as erasing ugly weld lines. Instrumented tests quantify the results achieved by this process.
Packaging Powerhouse Does It All
