In manufacturing processes, the flow chart is often the first step in designing a process, then when the process has been established, the flow chart is applied as part of process improvement, problem investigation and staff training efforts. Manufacturing processes are ideally suited for analysis via flow charting, due to the consistent ...

Stamping process design includes procedures to ensure that when material of the specified formability is used, splits do not occur. The foundation of these procedures is the forming limit diagram (FLD) [17].The FLD is a graph with axes of minor strain on the x-axis and major strain on the y-axis, 7 as shown in Fig. 2.10.Upon this graph, a line exists which separates the areas of strain space ...

Sheet Matel Material Used in the Process. The common materials used in manufacturing sheet metal are aluminum and stainless steel. The most known grades available in stainless steel are 304, 316 and 410. 304 is one of the most common grades. However, it is not available in the form of a sheet. The other two grades are much resistant and ...

Our Manufacturing Process. Once a coil of aluminum has been released for production, it is sent through one of our large-bed, high-tonnage stamping presses. Each press contains a series of dies which gives the metal its defining shape and character. As the shingle progresses through each die (from five to eight depending upon the product), the ...

This process, called the butt-weld process is the basis for our current pipe-making procedures. In his method, thin sheets of iron were heated and drawn through a cone-shaped opening. As the metal went through the opening, its edges curled up and created a pipe shape.

The melting process is key to glass quality; and compositions can be modified to change the properties of the finished product. Stage 2: Float bath. Glass from the melter flows gently over a refractory spout on to the mirror-like surface of molten tin, starting at 1,100°C and …

The metal is treated either before or after the stamping process to increase hardness or imbue the part with corrosion resistance. While stainless steel is a specific alloy that can resist corrosion, other steels need to be galvanized to prevent rust and damage.

enabling it to conduct an electric current. The high-velocity plasma jet melts the metal of the work piece. The cut produced by plasma jet is very clean and its quality can be improved by using a water injection arc plasma torch. Plasma cutting can be used on thicknesses upto about 150 mm but the process is very slow. 2.2.4 Cold Sawing

In sheet metal forming practice, we distinguish five basic modes of deformation: • STRETCHING: The material is expanded in both directions. This mode of deformation is found mostly on smooth bottoms of shallow parts and in hydroforming processes. • DRAWING: This mode is typical the material flow from the flange towards the
