1、 Influence of mold shell temperature. The temperature of the mold shell in professional injection molding has a significant impact on the precision of product specifications. The Mobe temperature immediately affects the shrinkage rate transformation of the product based on the trend and crystallinity of the molten polymer, leading to specification deviation.
For amorphous resins, the mold temperature is high, the solution cools slowly, the molecules have sufficient relaxation time, the crystallization trend is more complete, the crystallinity is high, and shrinkage increases. But for crystalline resins, during the entire process of professional injection molding, high mold temperature can reduce post shrinkage, making the product specifications stable.
If the mold temperature is low, the cooling is fast, and the molecular structure of the solution is not relaxed enough due to the tendency of freezing and cleaning. It is not easy to crystallize, and the volume change is small, resulting in small shrinkage of the product. However, low mold temperature increases the post shrinkage of the product, prolongs the shrinkage time, and makes it difficult to smoothly inject the specifications of the processed parts. Temperature is a sensitive element in the entire process of crystallization, and the crystallization rate can vary several times by a temperature difference of 1 ℃. The uneven or unstable temperature of the mold shell immediately affects the size of crystallinity, which in turn causes shrinkage of the injection molded product and leads to specification deviation.
2、 The impact of injection pressure. The change in injection pressure causes fluctuations in the size of the product. When other injection molding process parameters remain unchanged, increasing the injection pressure can improve the melt filling activity, increase the activity length, accelerate the filling speed, compact the product, reduce shrinkage, but easily generate orientation stress. When the pressure is low, the product cannot be fully compacted, resulting in increased shrinkage.
3、 The impact of holding pressure. The holding pressure plays an important role in stabilizing the size of the product. In the injection molding process, increasing the holding pressure can supplement and compact the shrinkage of the product in the mold, reducing shrinkage. But if the holding pressure is too high, it will cause an increase in residual stress during demolding of the product, causing deformation or cracking, and affecting the size of the product.
4、 The impact of injection time. Before the gate is closed, the shorter the injection time, the greater the shrinkage rate, and the greater the magnitude of the shrinkage rate change; When the injection time reaches or exceeds the solidification time of the gate, even if the injection time is further extended, the quality and shrinkage rate of the injection molded product will no longer change. The injection time control is closely related to the designed gate thickness, and the gate thickness can greatly affect the gate closing time.
5、 The impact of holding time. The longer the holding time, the more favorable it is for melt filling and compaction. The higher the density of injection molded parts, the smaller the shrinkage rate. After the gate is sealed, the pressure holding has no effect on reducing the shrinkage of professional injection molded products. Excessive pressure holding time will prolong the molding cycle.
