Valve gating

Instrument (letters indicate function) 12. Block valve (gate valve)... [Pg.107]

A valve is a mechanical device that controls the flow of liquids, gases, or loose material through piping systems. There are many types of valves, including butterfly valves, gate valves, plug valves, ball valves, and check valves. [Pg.209]

To mold micron-scale precision parts with shot weights of only 0.0022 g, electrical operating IMMs are being used. Those who desire precise shot size (dosing) can buy electric injection machines with servomotors capable of very accurate screw positioning. With hydraulic IMMs, molders can install a valve gate that shuts when the correct amount of plastic has been injected into the mold. [Pg.218]

Encapsulation - This term means to enclose as in a capsule. Polytetrafluoroethylene (PTFE) can be used to encapsulate metal articles to impart chemical resistance to them. Examples include encapsulated metal gaskets and butterfly valve gates. The metal provides mechanical strength and resistance to creep. [Pg.527]

Valve gating nozzles used in sprueless molding also belong in the general category of shutoff nozzles, as do the nozzles which are used for impact molding. [Pg.264]

Gating nozzles, hot-runners and insulated runner molds, nozzle manifolds, and valve gating nozzles are used for obtaining sprueless moldings. Elimination of the sprue and runner system reduces costs through scrap and labor savings. [Pg.264]

The most sophisticated type of gate is valvegating. It is used in both hot and cold runner molding. The principle of valve-gating is that the opening and closing of the gate is controlled by mechanical means such as hydraulic or pneumatic... [Pg.338]
