Machine learning models narrow down solutions in synthesis, compounding, product design, and more.

INEOS Styrolution announced the permanent closure of its polystyrene production site in Channahon, Illinois, with decommissioning and an orderly closure process expected to be completed in the fourth ...

Keith Luker is at it again. The CEO of Randcastle Extrusion Systems continues developmental work on his patent-pending Molecular Homogenizer (MH) mixing screw and has been busy releasing test data ...

Mokon has launched a new low global warming potential (GWP) portable chiller Iceman Micro Series. Featuring the R-513A low GWP refrigerant, the chiller lowers environmental impact by reducing the ...

In order to maximize your processing window, vents should be as deep as possible without causing flash. That depth is based on several factors, such as the type and grade of material, part geometry, ...

In valve-gated hot-runner molds, there is no need to differentiate between pack and hold times, because once the gate is mechanically shut after packing, the holding phase does not exist. Photo Credit ...

In November 2020 as part of its Tech Days webinar series, Plastics Technology hosted a session on “Establishing & Maintaining a Robust Molding Process,” in which I participated. During this webinar ...

Acrylic polymers were developed in Germany over the course of around 70 years, despite technical and economic hurdles and battles over intellectual property and professional pride. (Photo: Evonik) ...

Repeatability means the ability to produce parts that have identical properties. It is therefore often necessary to assess production systems or their components in advance according to whether they ...

I especially enjoy writing articles on subjects that are important to our industry but are rarely given the attention they deserve. Maybe it’s because these topics are not often, if ever, discussed in ...

In a previous article, we briefly discussed the influence of time as the second important factor in the mechanical response of polymers. The flip side of time is strain rate. The rate of loading for a ...

Visible defects on the surface of a molded part appear as dull, glossy, or hazy areas, or as a rippled surface, called orange peel. Common points of occurrence include near the sprue or behind sharp ...
