Plastic mold processing is widely used in the plastic products industry and has a history of development for many years. However, some plastic mold manufacturers still have product color difference problems when processing molds, resulting in unqualified products. The experience of the mold processing industry has concluded that the factors that cause color difference in plastic mold processing include the following 4 points.




What are the factors that cause color difference in plastic mold processing




① Factors in terms of raw materials: including toner replacement, plastic material brand change, and setting agent replacement.




② Different types of raw materials: For example, PP material and ABS material or PC material require the same color, but there is a slight color difference due to the different material types, but a limited range is allowed.




③ Equipment process reasons: the temperature, pressure and melt time during the injection molding process will also cause color difference problems. In addition, process factors such as different batches of materials and different machine beers will also affect.




④ Environmental factors: Generally, the barrel is not cleaned, the drying hopper is dusty, and the mold is greasy.
