Plastics Assembly

by Trevor Larcheveque Branson Ultrasonics Corp. 3D printing (3DP) now is widely adopted for prototyping and developing new product designs because it allows plastic component and part prototypes to be developed, produced, assessed and modified far more quickly and economically than traditional injection-molded plastic parts, which require significant up-front investment in … [Read more...] about 3D-Printed Plastics Parts: To Weld or Not to Weld?

Static in Medical Device Manufacturing

by Matt Fyffe, Meech USA In 600 B.C., the philosopher and mathematician Thales of Miletus reported that after rubbing a piece of amber on the fur of a cat the amber attracted and held feathers. This was the first account of static electricity (literally, electricity at rest). What Thales observed was what we now know as triboelectric charging, where certain materials become … [Read more...] about Static in Medical Device Manufacturing

Plastics Bonding Design Considerations for Processors

by Andrew Scott, Henkel Corporation Today's production world constantly is looking to streamline production and create more reliable assemblies with faster and easier methods. Adhesives successfully have been used to displace solvent welding in the plastics industry. The most common bonding applications using plastics range from delicate medical components to heavy industrial … [Read more...] about Plastics Bonding Design Considerations for Processors

Adhesives for Assembly

by Edward A.Y. Fisher, engineering manager, Henkel Corp. Question: When choosing an assembly process for a manufactured part, why should adhesives be considered over other processes, such as welding? Answer: Adhesives offer several major benefits over other assembly methods. They distribute stress load evenly over a broad area, eliminating stress concentration that occurs … [Read more...] about Adhesives for Assembly
