When we use a variety of measures can not eliminate the injection molding mold deposits, the need to strengthen care and maintenance of the mold.
　　Initial injection mold deposit surface forming tooling die relatively easily cleared, and the exhaust passage cavity must be cleaned and maintenance (e.g. in the production of each batch of molding). A long time without maintenance and repair of mold, the mold is very difficult to remove after the formation of a thicker layer of mold deposits and time consuming.
　　Injection mold used in the maintenance and repair spray are: a release agent, a rust inhibitor, thimble oil, glue stains scavengers, mold cleaning agents.
　　Mold deposit is very complex chemical composition, must clear and try new methods, such as general solvents and various special solvent, oven sprays, caffeinated lemonade and the like. Alternative methods are unusual clean rubber track model.
　　When using hot runner molding and hot-sensitive material, the melt residence time becomes longer, thereby increasing the risk of material formed by the decomposition of the mold deposit. Clean screw injection molding machine.
　　Using a molding material sensitive to shear forces the size of a large runners and gates, multi-point gate can reduce flow from the low injection speed, reducing the risk of formation of mold deposits.
　　Efficient mold venting may be possible to reduce the formation of mold deposits, is provided in the exhaust gas suitable mold die design stage. The exhaust system is automatically cleared, or can easily remove the mold deposit exhaust mode is the best choice, improved exhaust system often results in reduced mold deposit on the mold.
　　Special non-stick coating covering the cavity surface, prevents the formation of mold deposits, testing and evaluation results should be coated. A titanium nitride surface treatment avoids the formation of mold deposit on the mold the mold.
