It is also a restriking operation used to sharpen or change an existing radius or profile. Coining ●Acold forming process ● Certain surface forms are produced with low material displacement ●The thickness of the material in the starting stock is altered. Principle--plastic deformation Coining Classification 　coining without flash 　coining with flash coining coining with flash coining without flash Coining Hotcoining（热压印 ） The laser coining （激光压印 ） Embossing（凹凸压印 ） UV coining （紫外压印 ） Nano-coining (纳米压印) Classification According to deformation Principle Coining Equipment Mechanical press Hydraulic press Hammer Coining Materials Carbon and alloy steels Stainless Steels Heat-resisting alloys Aluminum alloys Copper alloys Silver and Gold alloys Coining Technological Process coining trimming deflashing stock preparetion Coining Coining process of the material deformation Materials flow Materials fill the gap Punch compresses materials Materials deform around the punch Only forming in the surface of blank Without metal transverse flow The final process of part forming Copying Shorter loading time Higher risk of overloading Tool life is not long Characteristics Coining Applications The manufacture of coin Different forms medals Artistic tableware Decorative embossment The metal button Summary 点击此处添加说明文本 点击此处添加说明文本 点击此处添加说明文本 点击此处添加说明文本 点击此处添加说明文本 点击此处添加说明文本 点击此处添加说明文本 点击此处添加说明文本 Coining 加入另一种分类方法 * 插入三种设备图片 * 横着放 * 加入另一种分类方法 * 加入另一种分类方法 * 插入三种设备图片 * 横着放 * 加入另一种分类方法 *
