During an extrusion process it is essential to consider the surface finish of exposed product surfaces. As a general rule, the narrower an exposed surface, the more uniform its finish becomes. Webs, flanges and abrupt changes in metal thickness may show up as marks on the opposite surface of an extrusion, particularly on thin sections. The ...
Microextrusion is an outgrowth of microforming, a science that was in its infancy in the early 1990s. In 2002, Engel et al. expressed that up to that point, only a few research experiments involving micro-deep drawing and extruding processes had been attempted, citing limitations in shearing on billets and difficulties in tool manufacturing and handling.

Bunting then enrolled in a community college writing course. [4] Of her first published story, The Two Giants, she said, "I thought everybody in the world knew that story, and when I found they didn't - well, I thought they should." [5] Bunting died of pneumonia in Santa Cruz, California, on October 1, 2023, at the age of 94. [6]
A simple cross-section schematic of the slot-die coating process. Slot-die coating is a coating technique for the application of solution, slurry, hot-melt, or extruded thin films onto typically flat substrates such as glass, metal, paper, fabric, plastic, or metal foils.
Depiction of the loop extrusion process where a loop extruder lands (top), extrudes a loop (middle), and unbinds (bottom). Loop extrusion is a major mechanism of Nuclear organization. It is a dynamic process in which structural maintenance of chromosomes (SMC) protein complexes progressively grow loops of DNA or chromatin.
While it may be impossible ever to know for sure, several variables could be at play for those homes that survive, experts say: a smart, fire-resilient design; an owners’ preparation, like ...

Die swell is an expansion of the melt as the pressure is released, and is dependent on polymer chemistry and die design. After curing, the solid, continuous part is drawn onto a take-up roller or cut into transportable lengths, depending on the type of part. This process may vary significantly depending on the type of die and extrusion process. [1]
