First, let’s establish that every process must follow normal scientific molding protocol. With pack and hold at zero, the shot should be 95 to 98% full. Temperatures and pressures should be kept as ...

Most of the plastic products we use are made through injection molding, a process in which molten plastic is injected into a ...

A radical new process “vaporizes” plastic bags and bottles to help make recycled materials. American scientists say the innovative chemical procedure turns ubiquitous waste items into hydrocarbon ...

Waste conversion. A process that converts end-of-life plastics into carbon nanotubes is the subject of a patent application from Trimtabs Ltd. of Swansea, Wales. The patent application points out ...

The injection blow moulding process is a key conventional process that enables the production of hollow plastic parts from a pre-moulded semi-finished piece, commonly referred to as a preform. It ...

There are essentially three widely used technologies for manufacturing plastic products: Injection molding, extrusion, and blow molding. Injection molding is the most commonly used process for the ...

In the late 1940s, following wartime-driven innovation, the mass production of inexpensive plastics revolutionized American life. For the first time, plastic toothbrushes, bottles, kitchenware, and fu ...

A new way of chemically recycling single-use plastics might offer an incentive to keep them out of landfills. Ivan Radic via Flickr under CC BY 2.0 New research may offer a way to keep single-use ...
