What are the factors that cause the color difference in plastic mold processing
Plastic mold processing is widely used in the plastic product industry and has a history of development for many years. However, there are still some plastic mold processing manufacturers that have product color difference problems when processing molds, resulting in unqualified products. Guangzhou Ideal Technology Based on the experience in the mold processing industry, it is concluded that the factors that cause the color difference in plastic mold processing include the following 4 points.
① Factors in raw materials: including toner replacement, plastic material grade 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 different material types, but a limited range is allowed.
③ Equipment process reasons: The temperature, pressure and melting 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, there is dust in the drying hopper, and there is oil pollution in the mold.
