2. Permanent mold casting - Wikipedia

   en.wikipedia.org/wiki/Permanent_mold_casting

   The mold life is dependent on four factors: the mold material, the pouring temperature, the mold temperature, and the mold configuration. Molds made from gray cast iron can be more economical to produce but have short mold lives. On the other hand, molds made from H13 tool steel may have a mold life several times greater.

3. Giga Press - Wikipedia

   en.wikipedia.org/wiki/Giga_Press

   The mold is closed, and a low vacuum of 50 millibars (50 hPa) created by pumping the air out. A precise amount of molten metal is pumped from the holding oven into the casting chamber at 750 °C (1,400 °F), and forced into the mold using a high-speed plunger with an additional 8 millilitres (0.28 imp fl oz; 0.27 US fl oz) of lubricant.

4. Machining - Wikipedia

   en.wikipedia.org/wiki/Machining

   Machining is a manufacturing process where a desired shape or part is created using the controlled removal of material, most often metal, from a larger piece of raw material by cutting. Machining is a form of subtractive manufacturing , [ 1 ] which utilizes machine tools , in contrast to additive manufacturing (e.g. 3D printing ), which uses ...

5. Cutting tool (machining) - Wikipedia

   en.wikipedia.org/wiki/Cutting_tool_(machining)

   Cutting tool materials must be harder than the material which is to be cut, and the tool must be able to withstand the heat and force generated in the metal-cutting process. Also, the tool must have a specific geometry, with clearance angles designed so that the cutting edge can contact the workpiece without the rest of the tool dragging on the ...

6. Sprue (manufacturing) - Wikipedia

   en.wikipedia.org/wiki/Sprue_(manufacturing)

   The gate is the location at which the molten plastic enters the mold cavity and is often evidenced by a small nub or projection (the "gate mark") on the molded piece. Many scale-model kits are made from injection-molded plastic. Hobbyists typically remove the parts of a model kit from the runner using a sharp craft knife or razor saw. The ...

7. Continuous casting - Wikipedia

   en.wikipedia.org/wiki/Continuous_casting

   Within the twin-belt continuous casting machine, molten metal progressively solidifies on the mold surfaces as it moves through the mold region, with a sump of molten metal present between the solidifying outer surfaces. Belt coatings, texture, and gas layer modifications are used to fine tune the heat transfer rate from the cast metal to the belt.

8. High stock removal - Wikipedia

   en.wikipedia.org/wiki/High_stock_removal

   The stock removal rate is largely a function of the material's properties. This is expressed as the machinability of a material: the ease or difficulty of machining a particular material. The machinability of materials varies greatly; for instance, aluminium and magnesium have high machinability compared to titanium and other special metals.

9. Pattern (casting) - Wikipedia

   en.wikipedia.org/wiki/Pattern_(casting)

   Cores to accommodate holes can be seen in the bottom half of the mould, which is called the drag. The top half of the mould is called the cope. In casting, a pattern is a replica of the object to be cast, used to form the sand mould cavity into which molten metal is poured during the casting process. Once the pattern has been used to form the ...
