What process performance do Aerospace Micro Screws need to have?

2025,07,26

Aerospace Micro Screws are essential process equipment in the stamping process. The mold is related to the quality of Aerospace Micro Screws, so there are high requirements for the manufacture of Aerospace Micro Screws. In order to ensure the quality of mold manufacturing and reduce production costs. Aerospace Micro Screws manufacturing materials should have the following technical properties:

Forgeability: low resistance to hot forging deformation, good plasticity of stamping parts, wide forging temperature range, low tendency of forging cracks and cold cracks, and less precipitation of network carbides.

Machinability: large cutting volume, low tool loss, and low machining surface roughness.

Annealing processability: wide spheroidizing annealing temperature range, low annealing hardness, small fluctuation range, and high spheroidization rate.

Hardening ability: uniform and high surface hardness after quenching.

Hardenability: a deeper hardened layer can be obtained after quenching, and it can be hardened using a mild quenching medium.

Grindability: the relative loss of the grinding wheel is small, the limit grinding volume without burning is large, it is insensitive to the quality of the grinding wheel and cooling conditions, and there is no wear and cracks in the grinding of precision stamping dies.

Sensitivity to oxidation and decarburization: When heated at high temperatures, it has good anti-oxidation performance, slow decarburization speed, is insensitive to heating media, and is not prone to pitting.

The manufacture of Aerospace Micro Screws usually requires forging, cutting, heat treatment and other processes, which are difficult to process and have high requirements for manufacturing materials. Only with good processing performance can the manufacturing process of Aerospace Micro Screws be guaranteed to be free of process defects and stable in quality.
