NPE2015: The Right Show at the Right Time

In recent years, plastics trade shows in North America have sometimes been written off as out of fashion and in decline. But in around 140 days, a giant plastics trade show in Orlando seems likely to quash emphatically any notions of irrelevance for such industry events.

Injection Molding


In injection molding material is fed through a hopper into an extruder, where a reciprocating screw mixes and melts the material then injects it into a mold. Injection molding machines, or presses, are rated by tonnage, which expresses the amount of clamping force that the machine can exert to keep the mold closed during the process. Most polymers can be injection molded. The types of products that are molded are wide and varied, ranging from large automotive parts to tiny gears. Navigate from the Injection Molding Zone to more specific topics on all-electric/hybrid machine technology, liquid-silicone rubber molding, micro-molding and multiu-component molding.
