Production of packing tubes, comprises molding a shaped part with pressing force existed in the form of stencil and arbor, and cooling the parts in cooling stations
摘要
<p>The pressing force of molding parts are 78-85%. The pre-determined total pressing force for the compression. The cooling pressing force (55-65%) smaller than the molding force. In the process, the total time of an residual index function is 30-40%.</p>
