3 Drag flowers: product ejection Dou is too small or damaged mother die mold products leaving marks on the surface of filamentous mold opening direction. If it is because the product is too small partial stripping Dou drag produced flowers, Due to size and mold has been finalized, the possibility to change the mold has not, and generally does not allow the development cycle, then we how to solve this problem it? The method is also still there, there are two: First, to increase the level of the master mold surface polishing. This can reduce the friction coefficient of the product and the mold, reducing the drag of flowers produced. Second, try to increase the injection temperature and pressure and reduce warranty as to shorten the dwell time, to extend the cooling time, the product has shrunk to increase as much as possible when such a model would not have dragged basically spent 5. Deformation : After the product produced, or place some time after the partial or total generated warpage. Product deformation had occurred injection molded parts, if the top output imbalance reason to exclude the vast majority are due to internal reasons exist stress quality injection mold, and even cause serious point will cause the product to crack. The solution: from the design side, try to keep the product uniform throughout the thickness of plastic product design, the transfer of the use of the largest possible angle R wholesale vehicle injection, under construction residence permit product as symmetrical arrangement minimize vias, when various parts of the structure and the structure is quite different asymmetric case, as far as possible to avoid the use of materials plus GF. But the product is deformed electric tools injection of processing, general design has been finalized, the mold has been opened, as a method to improve the follow-up only from conditioners aspects to consider, we can proceed from the following aspects: A), in ensuring product structural strength and appearance of the former bank, can fit to reduce the injection temperature. B), holding pressure as small as possible, dwell time as short as possible. C), before and after different mold cooling water system, adjust the temperature according to the deformation around the mold die situation. D), the cooling time longer appropriate. E), creating a shaped jig. F), the product was slowly cooled at a certain temperature (the vast majority may be cooled at a constant temperature of hot water). G), annealing treatment. H), for defective products has been deformed, or customer returns of defective products, great value higher if the product can be used overcorrection holder holding the product and then the product is placed slightly below ambient temperature Tg 2 -4 minutes (or adjust the temperature of high-temperature direct blow duct products deformed part), which can make the product deformation recovery.
