See here, the new external wall insulation nails, you have no desire to buy these products do? If anything, it will be ideas into action! Do not wait any longer, come my factory order now! External wall insulation nail riser design: 1, for small volume contraction during solidification of alloys (such as gray cast iron), wall insulation nails, or no shrinkage concentrated alloys (such as bronze), insulation riser The main function is to collect the flow of gases and emissions from the cavity in the forefront of inclusions or mixed with liquid metal oxide film, in order to reduce defects on the casting. This riser more disposed opposite the gate, which do not have much size. 2, the requirements for controlling the microstructure of casting, riser can collect flow fronts cooled liquid metal to avoid cold tissue castings. Figure 2 is a single cast piston ring, opposite the inner gate to set up a small riser to collect cold metal, wall insulation nail factory, where it will not appear because of the metal is too cold and white tissue, leading to casting scrap . Such feeder size and installation position shall be determined by the microstructure of the casting requirements. 3, the large volume shrinkage during the solidification and shrinkage concentrated tend to form an alloy (e.g. steel, brass and aluminum bronze, manganese, etc.), the main role is to compensate for riser molten metal in the cavity and the liquid shrinkage castings solidification shrinkage, no shrinkage to obtain dense castings. .
