Injection molding cooling systems are the heart of the mold and very important for the entire injection molding process. An efficient cooling system plays a decisive role in optimizing the cooling time of injection molds and the entire production process. To ensure that the minimum cooling times are achieved, you must have a complete cooling and heating system. A fully cooling system can significantly reduce cooling time and thus improve the efficiency of your injection mold production. Cooling the injection molding is an essential step in the manufacturing process and once you have identified how to do this, you should
Preventing this is all about high-level design. I will discuss some molding defects that may occur in the injection molding process and how to repair and avoid them. Design defects we will discuss weld lines. Explanation: in fact, the weld line is more like a plane than a line that meets each other as the molten plastic flows from two different parts of the mold. Cause: When the molten plastic is partially solidified, it is caused by the insufficient combination of two or more flow fronts. Remedial measures: 1. You can raise the temperature of the mold or molten plastic.
The trapezoidal runner is preferred because it is easy to process and design. A full circle runner is acceptable and common and is necessary for some material types. All runner intersections will have an increased radius in the direction of flow and cold plugs will be provided at each intersection. Refer to drawing S3-1 for cold runner design guidelines. The design of the edge gate shall be “double chisel” type, which can be easily removed from parts. Refer to drawing S3-2 for edge gate design guidelines. Fan gate is usually used to help reduce part warpage or maintain flatness. Refer
