AI Technical Summary
Existing technologies cannot achieve high precision, high consistency, and low cost in the one-piece molding of spiral microneedles, and cannot meet the requirements for efficient heat dissipation.
Design a flat-bottomed plow-cutting tool for fabricating helical microneedles, including a handle, a plow-cutting blade, and a back-cutting blade. It adopts an isosceles triangular and prism-shaped cutting edge structure and combines a composite processing technology of the plow-cutting blade and the back-cutting blade to achieve efficient forming of helical microneedles.
It achieves high-precision, integrated molding of spiral microneedles, significantly improving processing efficiency and molding quality, reducing material waste, lowering production costs, and enhancing the heat exchange performance of heat dissipation devices.
