introduction:Weld lines are often generated during injection molding,Fuse connection is one of the most serious defects of injection molding products,It not only affects the appearance of the product quality,And the welding line has influence on the strength of the product,And in the painting and other post-processing,The fuse line is difficult to handle,So the length of the fuse line must be shortened。As fused resin fills each other the interface is displayed on the surface,Resulting in reduced strength and appearance,In order to withstand the external force of the parts or eye-catching parts do not produce welding,Move the fuse wire to a place that does not affect its appearance and strength,At this time can passCAESoftware predicts fuse position,Then by changing the product design
