Small problems in die cutting

The first thing to do with a solid die, the product is a die cut of Chow Tai Fook
.
The square hole and round space in the middle of production are to be cut through. In actual production, square hole and circular hole waste will not come out.

Die mold is hollow, can blow in the round hole and square hole position, the direction of blowing can be adjusted from the inside.

After the machine did not even know how to adjust the direction of blowing. How can no way to adjust the hole to blow off the waste.

Tune for a long time. Find yourself silly, adjust the route and direction of the material, solve the problem
