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

Feed system of mould

Feed system of mould It is necessary to provide a flow-way in the injection mould to connect the nozzle (of the injection molding machine) to each impresion.  This flow way is terned the feed system. Normally the feed system comprises a sprue, runner and gate. these terms apply equally to the flow-way itself, and to
