Press Release Summary:

December 16, 2013 - Used to securely attach components, microPEM® (Type MSIB™) inserts install permanently in range of plastic materials, from ABS to polycarbonate, and feature M1–M1.6 threads. Single mating screw completes joining process, and fasteners will install in either straight or tapered mounting holes. Symmetrical design eliminates need for insert orientation prior to installation, which is achieved by pressing insert into mounting hole using ultrasonic insertion equipment or thermal press.

Pennengineering Introduces Micropem® Inserts for Plastics Ideally Suited for Compact Electronic Assemblies

Press release date: December 10, 2013

New microPEM® thru-threaded brass inserts for plastics introduce ideal fastener solutions to attach components in compact electronic assemblies.  These fasteners with threads as small as M1 install easily and permanently in a wide range of plastic materials from ABS to polycarbonate.  They promote secure and reliable attachment for devices ranging from hand-held consumer electronics to medical equipment, among many others.  A single mating screw completes the joining process.

The microPEM (Type MSIB™) inserts will install in either straight or tapered mounting holes and their symmetrical design saves time during production by eliminating any need for insert orientation prior to installation.

Installation is achieved by pressing the insert into a mounting hole using either ultrasonic insertion equipment or a thermal press.  When installed ultrasonically, the frictional heat caused by the vibration then melts the plastic surrounding the insert and, when the vibration ceases, the plastic solidifies to lock the insert into place.  Use of a thermal press will melt the plastic surrounding the insert to result in permanent installation.

The microPEM inserts are available in thread sizes M1 to M1.6 and in several lengths. They join a growing family of microPEM fastener products and capabilities engineered to help enable smaller and lighter designs.

Detailed specifications (Bulletin MSI) and free part drawings (PEM CAD Library) for these RoHS-compliant inserts can be accessed at www.pemnet.com
