Aren't you adjusting the flow rate yet by machining the resin flow channels? I will explain in detail how to adjust the resin flow rate balance.
In the case of problems in irregular extrusion, a waviness phenomenon may occur. Looking at the CAE analysis diagram, it can be seen that the flow rate of the resin in the waviness area is fast, and the amount of resin flowing is large, which indicates that this phenomenon occurs. One method to adjust the resin flow balance is to change the length of the resin flow path (by modifying the internal resin flow path of the mold) or to adjust by changing the slit width of the mold. *For more details, please refer to the middle section of the page. Our company also accepts requests for extrusion mold design, prototype molding, and technical development tailored to customer needs, so please feel free to consult with us. 【Overview of Materials】 ■ Method to adjust by changing the length of the resin flow path - Adjusting the length of the die land ■ Adjustment method by changing the width (gap) of the slit - Adjusting the gap of the die land *For more details, please refer to the PDF materials or feel free to contact us.

basic information
<Adjustment Method by Changing the Length of the Resin Flow Path> Advantages 1. Since the change in resin amount due to cutting adjustments is not significant, it is easy to adjust. (Easier to predict) 2. Because the change in resin amount due to cutting adjustments is not significant, there are fewer failures from over-cutting. (Fewer failures due to excessive cutting) Disadvantages 1. Cutting corrections take time. 2. Cutting work cannot be done by just anyone; it requires specific skilled workers. 3. Since the changes from adjustments are gradual, the number of trial and error instances increases. 4. Cutting can easily change the flow of resin inside the mold. (Cross-flow is more likely to occur, leading to instability in molding) <Adjustment Method by Changing the Width of the Mold Slit (Gap)> Advantages 1. Since it can be handled with wire processing, it takes less time than cutting adjustments. 2. No need for skilled workers in mold cutting. 3. The changes from adjustments are significant, reducing the number of trial and error instances. Disadvantages 1. The change in flow rate is significant, making it easy for the change in resin amount to exceed expectations. 2. It is difficult to predict how much to change the slit width. 3. If the prediction is off and the resin flows too much, it cannot be reverted. (In the worst case, it may require remaking.)
