Trapped gas has long been the bane of plastic molders. It causes incomplete fills, gas burns, and knit lines, and can ruin product quality. A new porous steel, called Porcerax, vents trapped gasses through the plastic mold's walls, while retaining the resin in the mold.
According to Tom Schade, VP at International Mold Steel, "Porcerax eliminates the need for complex venting systems normally required for fine hair-like parts such as speaker grills or large complex assemblies such as car doors. You don't have to build the entire mold from Porcerax," explains Schade. Usually a small piece (or pieces) in the right place, vents trouble-causing gas. The material comes in two shapes--flat plates and bars--providing a variety of design options for mold makers.
According to Schade, choosing the right steel for the mold is the most cost effective way to improve productivity and quality. To this effect, the company offers several new materials. One example is a new pre-hardened H-13 type, 40 RC mold steel called DH2F. The material reportedly cuts fabrication costs for die and mold makers because it machines about 30% faster than other H-13 steels of similar hardness. "It also eliminates the need for heat treatments," adds Schade.
Another example is PX5, a replacement for P-20, that also machines about 30% faster, according to Schade.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
With LEDs dropping in price virtually every year, automakers have begun employing them, not only on luxury vehicles, but on entry-level models, as well.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
