1.Avoid variations in part thickness by adding gates to thicker areas. Depending on the product's intended use, prioritize materials with good flowability and thoroughly dry them (drying at 85°C for four hours is recommended, avoiding high-temperature, short-term drying). Adjust the mold temperature to increase and the barrel temperature to decrease, and insulate the barrel nozzle to thicken the flow edge, ensuring stable material flow.
2. Avoid uneven part thickness during design by adding gates to thicker areas. During mold manufacturing, ensure sufficient cooling within the mold (extend the cooling time). Adjust the barrel temperature to increase and the injection pressure to decrease to ensure uniform cooling and improve overall processing accuracy.
3. Increase the mold and barrel temperature and injection pressure; add venting grooves 0.02-0.04mm deep and 5-10mm wide on the parting surface; enlarge the gate and flow edge. For multi-cavity molds, expand the gate for underfilled cavities, adjust the flow edge configuration, and install mold components such as vent pins to improve the mold's finish and reduce processing defects.
4. Eliminate part thickness variations by placing gates in thicker areas. During mold fabrication, straight lines prone to warping can be designed as large R curves, and molds designed to allow for reverse bending of the part can be used. Increase the number of mold accessories, such as ejector pins, and increase the draft angle to optimize demolding.
5. Increase the injection pressure, extend the hold time, reduce the barrel and mold temperature, and force cool the dents. Add flow edg.
