The advantages of the ring gate shortcomings

1. Melt down evenly around the gate into the cavity, the gas out smoothly, so the exhaust effect is good.

2. The melt on the entire circumference of roughly the same flow rate can be obtained, no ripples and weld marks.

3. Because of melt in the cavity to the smooth flow of products of the internal stress is small, the deformation is small.

4. Ring gate area is big, remove the difficulty, and on the left side is obvious.

5. Due to the gate residue is more, and in the products outer surface, to make it beautiful, commonly used cutting and cutting method to remove.
