Manufacture method for shock insulation plug, shock insulation plug, and manufacture device for shock insulation plug

The invention provides a manufacture method for a shock insulation plug, a shock insulation plug, and a manufacture device for a shock insulation plug. Without lead as a material, attenuation performance and displacement servo of a shock insulation device can be further improved. The manufacture method for a shock insulation plug (9) is characterized in that, a pair of pressing dies (5) are used to clamp a powder material (2) to perform pressing and forming of the powder material (2), at least two times of pressing and forming are adopted in a way that, when a convex pressing die (6) and a concave pressing die (7) are used to perform pressing and forming, then the pressing dies (6, 7) are made to rotate around the axis center, and secondary pressing and forming is performed, from the front view of the cross section cut out in the axis direction X of the pressing die (5), the convex pressing die (6) is provided with a V-shaped pressing surface protruding from the central part (12) of the pressing die to the pr
