The process of plastic injection mold processing needs to control not only the injection molding process, but also the use of the injection mold. Gates are one of the important components of plastic injection molds, and their types are also diverse. Different gate types can be used on different molded parts. The types of gates commonly used in plastic injection mold processing include What are you?
 

1. Direct gates. At present, direct gates are commonly used in injection molding molds. The advantage is that the pressure of the melt during the injection molding process is relatively small, and it is also easier to form, direct gates. The advantages make it suitable for more commonly used plastics, such as some relatively large and deep molded parts.

2, rectangular gate, the location of the rectangular gate is generally open on the parting surface of the plastic injection mold, which is used in the injection mold of small and medium-sized injection molded parts. The advantage is that the cross-sectional shape is relatively simple, it is relatively easy to process, and it is also easy to modify after the plastic injection mold is used later. However, the disadvantage of rectangular gates is that it is easier to produce gate marks.

3, fan-shaped gate, fan-shaped gate is actually a variation of the rectangular gate, so it has many similarities with the rectangular gate. However, scalloped intersections are generally more suitable for injection molding large flat and thin-walled injection molded parts.
