First Technique: Moulding Metal Post Caps

Make mould resembling shape of the sheet metal post cap without changing its size or the volume.

Melting: Metals are melted to a uniform, processable object to be later flattened and pressed into a sheet.

Pouring: The metals are poured into a rectangular mold and out of the crucible once the metal is completely liquified.

During this process, the sheet metal should stay in a liquid state so that it does not begin to harden outside the mold.

Cooling: Allow the sheet metal to cool. Once cooled, it forms a rectangular object and into the shape of the mold.

Remove the sheet metal through a repetitive motion by applying a strong force.

Bending the metal involves to change a piece of sheet metal shape without its volume being affected. Use a press brake technique for bending by shaping the material into the required angle.

Welding/ Joining

Here you fuse the metals and they will solidify in the new shape as they cool by heating them to a high temperature.

Surface Finish For Sheet Metal Post Caps?

This roughens a smooth surface, removes contaminant surface, smoothen a rough surface or shape a surface.


An object of different types of metal is coated using a layer of metal through this surface finish. Plating is commonly done for more practical reasons such as corrosion resistance and wear and tear protection or for aesthetic purposes.
