Cold-pressed juice
Making cold-pressed juice is a two-step process. The first stage is to shred the fruits and vegetables into a pulp. Typically the shredding process uses a steel rotating disc. Produce is loaded into a large hopper feeding tube and typically falls into a filter bag. The second process is the hydraulic press; this exposes the shredded produce to extreme pressures between two plates. The pressure causes the juice and water content from the produce to drip into a collection tray below, leaving behind the fibre content in the filter bag. The fibre left behind is generally composted, recycled in food products or discarded.
Cold stamping
Cold stamping, also known as press working, is a manufacturing operation in which thermoplastics in sheet form are cold-formed using methods similar to those used in metalworking. A precut thermoplastic sheet, possibly reinforced, is softened by heating to a temperature particular to the plastic in use. The heated sheet is then shaped by stamping using a press. Fiberglass-reinforced thermoplastic sheets are formed using metal stamping presses after the sheets are preheated to about .
