Common mould polishing methods and working principle mechanical polishine Mechanical mould polishing is a polishing method that removes the convex surface of the surface of the workpiece by cutting or plastically deforming the surface of the material to obtain a smooth surface. Generally, oil stone strips, wool wheels, sandpaper, etc. are used, which are mainly
Injection mold manufacturing can be roughly divided into the following steps: First, the process analysis of plastic products. Before the mold design, the designer should fully analyze whether the plastic products meet the injection molding processing principle, and need to carefully negotiate with the designer of the product, and a consensus has been reached. This
Bench of mould irrespective of the machine tool or technique used to manufacture the various parts of the mould, the final responsibility for the finishing of the individual parts and for fitting them together lies with the bench fitter. The mould finishing and assembly procedure adopted by the bench fitter varies from toolroom to toolroom;
Talk about mould cooling One fundametal principle of injection molding is that hot material enters the mould, where it cools rapidly to a temperature at which it solidifies sufficiently to retain the shape of the impression cycle.while the melt flows more freely in a hot mould, a greater cooling period is required before the solidified
Parting surfaces of injection mould General The parting surfaces of a mould are those portion of both mould plates,adjacent to the impressions,which butt together to form a seal and prevent the loss of plastic material from the impression. We can classify the parring as being either flat or mom-flat.Examples of the latter type include stepped,profiled
mould temperature One fundamentak principle of injection molding is that hot material enters the mould,where it cools rapidly to a temperature at which it solidifies sufficiently to retain the shape of the impression. The temperature of the mould is therefore important as it governs a portion of the overall molding cycle.While the melt flows more
Sprue Bush and Register Ring The sprue bush is defined as that part if the mould in which the sprue is formed.In practice the sprue bush is the connecting member between the machine nozzle and the mould face,and provides suitable aperture through which the material can travel on its way to the impressions or
