Influence of injection molding process conditions
In the operating conditions of plastic parts molding, the temperature, time, pressure and the orientation and molecular crystallization produced during molding will affect the accuracy of the size of the old plastic, and the instability of the shrinkage of the plastic part will cause the molding conditions to occur. Changes will directly lead to the generation of dimensional errors. If the temperature in the plastic melt is higher, the pressure in the cavity is transmitted faster, and the shrinkage of the plastic part is smaller, the dimensional accuracy will also become higher. However, the mold temperature is higher, Large temperature difference and winding knots will reduce the accuracy of the guide scale
3.1 The influence of mold temperature The temperature is the factor that has the greatest impact on the accuracy of the ruler in injection molding. The mold temperature is due to the low cleanliness and the orientation of the molecules that have a direct impact on the shrinkage rate, resulting in dimensional errors. For the non-finished tree, it has the characteristics of high mold temperature and slow melt cooling. The molecules have enough time to relax. After the completion of the product history, the H grade is higher, and the shrinkage naturally increases. For resins with high quality, the nanomold temperature can be reduced after harvesting, which has a beneficial effect on the size and sugar content of the product. The main body is: low temperature line, fast cooling speed, and melt molecules cannot relax after being frozen. It is difficult to produce fusion, and the volume change is small, so the foil of the product becomes smaller, which guarantees the accuracy of the small size. 3.2 The influence of the injection pressure The change of the injection pressure changes the size of the product. On the basis of the other process parameters: , By increasing the injection pressure, the fluidity of the melt can be effectively modified, and the flow length is increased from the surface, the orange filling speed is accelerated, and the shrinkage rate is reduced. However, this rod is prone to oriented stress in a lower pressure state. , The product cannot be fully compacted, and it is easy to increase the shrinkage rate
3.3 The influence of holding pressure The holding pressure has a great impact on ensuring the stability of the product with a small size. By increasing the holding pressure, the product can be filled and compacted, and the shrinkage is reduced from the rain, but the holding pressure If it is too large, it will lead the product to be affected by the larger residual stress during the mold, resulting in deformation or cracking, which will adversely affect the size of the product
3.4 The influence of injection time Before the gate is closed, the injection should be carried out. The shorter the injection time, the greater the shrinkage rate. If the injection time is greater than or equal to the gate solidification time, even if the injection time is extended, the quality of the product will be The shrinkage rate remains the same 35. The influence of the holding pressure time The holding pressure time is positively related to the plastic filling and compaction of the melt. The longer the pressure holding time, the smaller the density of the part, and the shrinkage rate will also decrease. After the gate is sealed, the function of holding pressure will be invalid, and too long holding time will prolong the forming cycle.
