In the case of problems in irregular extrusion, a wavering phenomenon may occur. Looking at the CAE analysis diagram, it can be seen that the flow rate of the resin in the wavering part 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 the slit width of the mold. *For more details, please refer to the middle section of the page. Our company also offers extrusion mold design, prototype molding, and technical development tailored to customer requests, so please feel free to consult with us. 【Overview of Materials】 ■ Method of adjusting by changing the length of the resin flow path - Adjusting the length of the die land ■ Method of adjustment 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.
