Penn State, Private Industry Offer Tutorial in Powder Injection Molding

Today’s powder injection molding process is very sophisticated, with many processing variables and a high degree of material complexity. To help industry professionals improve their understanding of this process, the Center for Innovative Sintered Products (CISP) at Penn State University in the United States is teaming up with a private company, Innovative Material Solutions, Inc., to offer a two-day tutorial covering the most important factors in successful powder injection molding.

The hands-on tutorial, scheduled for October 22-23, will be held in Penn State’s home town of State College, Pennsylvania, about 220 km north of Washington, DC. The tutorial will be suitable for people new to the technology or those investing it for future applications. Following the tutorial’s presentations, there will be demonstrations at CISP’s P/M Lab
