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 ...

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 ...

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 ...

Scientists invent process that converts plastic bottles into paracetamol, which is a common drugstore painkiller used in ...

Polyethylene plastics -- single-use bags and general-purpose bottles -- are indestructable forever plastics. That also makes them hard to recycle. Chemists have found a way to break down the polymer - ...

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 ...

In the late 1940s, following wartime-driven innovation, the mass production of inexpensive plastics revolutionized American ...
