Mold processing designers must have rich experience in design and injection molding. For precision mold processing, the relationship between these factors and injection molding conditions and their apparent factors must be considered, such as injection pressure, cavity pressure and mold filling speed, injection melt temperature and mold temperature, mold structure and gate type and distribution. The effects of gate area, wall thickness, filler content in plastic, plastic crystallinity and orientation are discussed. The influence of the above factors also varies with plastic materials or other molding conditions, such as temperature, humidity, continuous crystallization and molding machine.
In the research on the relevant technical factors affecting mold processing, mold is the key to obtain precision plastic products that more meet the requirements of teaching quality management. Mold design, mold structure design, whether the enterprise is reasonable will directly affect the quality of plastic products.
Because the injection molding process is the transformation process of plastic from solid (powder or particle) to liquid (melt) to solid (product). Precision die processing, from particle to melt, and then from melt to product, through the action of intermediate temperature field, flow field and density field. Under the joint action of these fields, different plastics (thermosetting or thermoplastic, crystalline or amorphous, reinforced or unreinforced, etc.). It has different polymer structures and rheological properties. All factors affecting the above “field” will certainly affect the physical and mechanical properties, size, shape, accuracy and appearance quality of plastic products.
Due to the combination of process factors, polymers, structural forms and plastic materials, the mold of the finished product will be displayed. As long as the mold processing master can be familiar with the previous relationship of these materials, plus the specific processing technology and drawings, a mold can be made.
