Moldi mater industriae sunt, et importantia moldii populi cognoscetur. Designa moldi et fabricantia praevaluerunt. The transformation of mold processing skills, the widespread application of various new mold materials, and the standardization and specialization of mold components have forced stamping mold factories to become more precise and quickly accustomed to the development of molds in design.

So, in the stamping process, what functions are mold parts needed to have in order to facilitate the precision and service life of the mold?

1. Wear resistance

When the billet undergoes plastic deformation in the mold cavity, it flows and slides along the surface of the cavity, causing severe conflicts between the surface of the cavity and the billet, which leads to the failure of the mold due to wear and tear. Itaque resistentia materiarum est unus de fundamentalibus et multo importantibus functionibus molorum.

Hardness is the main factor affecting wear resistance. Generally, the higher the hardness of mold parts, the smaller the wear amount, and the better the wear resistance. In addition, wear resistance is also related to the variety, quantity, shape, size, and dispersion of carbides.

2. Focus temperaturae alta

Quando alta est temperatura functionis pulveris, diminuet difficilium et fortitudinem, mane portare aut deformationem plasticae mortis et defectus.

3. Resistentia corozionis

Some stamping molds, such as plastic molds, contain elements such as chlorine and fluorine during operation. When heated, they decompose and release highly corrosive gases such as HCI and HF, which corrode the surface of the mold cavity, increase its surface roughness and exacerbate wear and failure.

4. Strong patience

Conditiones functionis moldii multo difficile sunt, et alii saepe multas implantes portant, quae potent inducere ad fractam fractam. idcirco, moldii fortitudinem et durabilitatem habere opus sunt. Durabilitate molae prima dependt de sature carbon, granditudine grani et microstructura materiae.

5. Cold and hot fatigue resistance function

Some stamping dies are in a state of repeated heating and cooling during the work process, causing the surface of the mold cavity to be subjected to tensile and compressive stress, resulting in cracking and peeling of the surface, increasing the conflict force, preventing plastic deformation, reducing dimensional accuracy, and ultimately leading to mold failure. Cold and hot fatigue is one of the main ways in which hot work molds fail, and such molds should have high resistance to cold and hot fatigue.
