New air filtration system sucks out the bad, leaves the good in moldmaking facilities

By Clare Goldsberry
Published: January 10th, 2011

Air quality in mold manufacturing facilities is a big concern, and many companies take measures to improve it, such as through-the-wall fans that suck up smoke and vent it outdoors, and/or vacuum systems over carbon-grinding machines that vent to a filter unit outside.

There are many causes—and sources—of air quality problems throughout the metalworking sections of a plant. Most metal/aluminum machining and polishing processes create an extremely fine dust that can create a smoke-like haze throughout the entire facility.

Sheet shows tool surface pressure variations

By PlasticsToday Staff
Published: January 7th, 2011

A new surface pressure indicating sheet from Sensor Products Inc. (Madison, NJ) is said to improve yields and reduces defects in the injection molding process by minimizing flash, shorts, and burns, among other defects. The primary purpose of Mold-Align is to indicate mold face planarity. When placed between mold halves that are compressed together, the material instantaneously changes color revealing how pressure is being distributed between the mold faces.
