How do the surface of the injection molded parts be not smooth?
Injection molding parts processing is to produce some plastic products when it must be used, but a lot of injection time will appear some problems, this kind of problem is more difficult for us, there will be a lot of problems, then in the process of injection molding, what will happen? We should have little understanding of it, after all, this is what we can not reach, and when you introduce the surface of the plastic parts processing, when the surface is not smooth, how should we do it! You can understand it.
Cause of unsmoothed surface of injection molding parts
One, the time of material cooling is not sufficient is one of the reasons for the wrinkling of the injection processing. In the case of short time, the plastic itself is very soft, and it does not reach the standard of molding. At this time, the molding product is very easy to be warped.
Two, the low temperature of the material tube is the key factor causing such problems. When the temperature is low, the temperature of the material will become relatively low, and the products of this kind can only be formed only reluctantly, but because there is not enough time, the product will be easily warped because of the pressure release. If we raise the relative temperature, we can reduce this situation.
Three, the pipe can be divided into four regions. Under normal circumstances, the temperature in the latter area should be higher than that in the preceding area. The higher temperature should be controlled at around six degrees Celsius. However, this way of setting is not absolute. Under specific circumstances, we can make certain changes. Even sometimes, the temperature of the two zones may be consistent.
