AI Technical Summary
During the injection molding process of building blocks, uneven distribution of metal powder can lead to surface defects, affecting the flatness and aesthetics of the product surface, and reducing the splicing accuracy and pass rate.
The injection fluid uses functional particles, and the flow channel's injection direction forms an acute angle with the convex curved surface of the functional end. The injection fluid impacts and changes its flow direction within the cavity. Combined with the planar design of the nozzle tip, it suppresses the problem of leaving marks.
It improves the aesthetics of the building block surface and the accuracy of the assembly, reduces defects and marks, and increases the product qualification rate and fun.
