The casting is usually a fine-grained casting with an especially fine-grained outer diameter, due to the rapid cooling at the surface of the mold. Lighter impurities and inclusions move towards the inside diameter and can be machined away following the casting. Casting machines may be either horizontal or vertical-axis. [1]
Behind the finished vase are the spinning tools used to shape the metal. Metal spinning, also known as spin forming or spinning or metal turning most commonly, is a metalworking process by which a disc or tube of metal is rotated at high speed and formed into an axially symmetric part. [1] Spinning can be performed by hand or by a CNC lathe.
These processes include planar flow casting, twin roll melt spinning, and auto ejection melt spinning. Originating with Robert Pond in a series of related patents from 1958 to 1961 (US Patent Nos. 2825108, 2910744, and 2976590), the current concept of the melt spinner was outlined by Pond and Maddin in 1969.
Spin casting is commonly used for the manufacture of the following types of items: Gaming miniatures and figurines – in both metal and plastics. Fishing lures and fishing tackle components including jig heads and lead weights. Decorative and novelty type items – belt buckles, pins, emblems, medallions, trophies, assorted souvenirs etc.
The Fly Casting Analyzer is a unique system that measures the casting stroke of an individual casting a fly line with a fly rod. A sensor attached to the reel seat measures your rod speed and a Palm pilot (or Palm cell phone) then records the casting signature. A Palm application immediately analyzes the casting signature by breaking it down ...
Spin casting is a technique for constructing large parabolic mirrors by using the curved surface formed by a rotating liquid (e.g. in a rotating furnace). [1] It is distinct from the spin casting or centrifugal rubber mold casting (CRMC) technique used for casting metal or plastics.
Rolling schematic view Rolling visualization. In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property.
For double-acting single-rod cylinders, when the input and output pressures are reversed, there is a force difference between the two sides of the piston due to one side of the piston being covered by the rod attached to it. The cylinder rod reduces the surface area of the piston and reduces the force that can be applied for the retraction stroke.
