The two-step extrusion method was used to manufacture pipe-grade high density polyethylene (HDPE) material from recycled HDPE. With the two-step extrusion method, dicumyl peroxide (DCP) can completely ...

Scientists have developed a vacuum-assisted extrusion method that reduces internal porosity -- by up to 75% -- in large-scale 3D-printed polymer parts. Large-scale additive manufacturing has been ...

On the right, a vacuum-assisted extrusion is leveraged in large-scale additive manufacturing to reduce porosity in printed parts. The inset image, on the left, is a close-up of the vacuum-assisted ...

Macro Engineering & Technology Inc. has developed and patented a new process to produce trash bags using post-consumer materials. With conventional methods for producing bags with high amounts of ...

Aluminum is particularly well suited to the extrusion process due to its excellent plasticity at extrusion temperature. Only a minor degree of work-hardening takes place at this temperature and ...

Packaging of a number of consumer products is done in tubes or bottles wherein product application involves pumping the product through a nozzle. These products are basically shear-thinning products ...

Four Masters students from Bartlett School of Architecture - Francesca Camilleri, Nadia Doukhi, Alvaro Lopez Rodriguez and Roman Strukov - have developed a new method for 3D printing large-scale, self ...
