Machine shut-off nozzles serve as the connection between the plasticizing barrel (with reciprocating screw) and the mold. They are mounted on the machineside of the plastic injection molding process, unlike hot runner nozzles which are mounted on the moldside of the process.
Parts washers were originally developed for use in automotive transmission and engine repair shops as a way to improve the function of simple soak tanks.Soak tanks are vats filled with a mixture of water and detergent, which take hours to "soften" the built-up road grime, fluids, tars and oils enough to be manually rinsed off prior to disassembly and repair.
By contrast, a cold runner is simply a channel formed between the two halves of the mold, for the purpose of carrying plastic from the injection molding machine nozzle to the cavities. Each time the mold opens to eject the newly formed plastic parts, the material in the runner is ejected as well, resulting in waste.
Injection moulding (U.S. spelling: injection molding) is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals (for which the process is called die-casting ), glasses , elastomers , confections , and most commonly ...
A pressure washer is used to remove old paint from a boat. Patio flagstones being pressure washed using a rotary nozzle. Pressure washing or power washing is the use of high-pressure water spray to remove loose paint, mold, grime, dust, mud, and dirt from surfaces and objects such as buildings, vehicles and concrete surfaces.

Paper clip mold opened in molding machine; the nozzle is visible at right A injection molding machine with a robot. An injection molding machine (also spelled as injection moulding machine in BrE), also known as an injection press, is a machine for manufacturing plastic products by the injection molding process.
Spray nozzle manufacturers all tabulate capacity based on water. Since the specific gravity of a liquid affects its flow rate, the values must be adjusted using the equation below, where Qw is the water capacity and Spg is the specific gravity of the fluid used resulting the volumetric flow rate of the fluid used Qf.
