Stamping Die When molding high-quality stamping parts, the surface finish of the mold plays a vital role.
1. Reduce friction and wear
Reduce friction coefficient: A high-smooth mold surface can significantly reduce the friction coefficient between the material and the mold during the stamping process, reducing friction, thereby reducing the wear of the mold and material.
Extended mold life: Smooth mold surface can reduce micro-scratches and wear, extend the service life of the mold, and reduce the frequency of maintenance and replacement.
2. Improve the surface quality of stamping parts
Reduce surface defects: The high surface finish of the mold can reduce material adhesion and scratches during the stamping process, thereby reducing surface defects of stamped parts, such as scratches, pitting, etc.
Improve surface finish: The high finish of the mold surface can be directly transferred to the surface of the stamping parts, ensuring that the stamping parts have high finish and good appearance quality.
3. Ensure the dimensional accuracy of stamping parts
Stable dimensional control: The high-gloss mold surface helps maintain the shape and dimensional stability of the mold cavity, thereby ensuring the dimensional accuracy and consistency of stamping parts.
Reduce springback and deformation: The smooth mold surface reduces the stress concentration of the material during the stamping process, helping to reduce the springback and deformation of stamping parts and improve dimensional accuracy.
4. Improve production efficiency
Reduce material adhesion: The high-gloss mold surface reduces the possibility of material adhesion to the mold, reduces the time and cost of cleaning the mold, and improves production efficiency.
Reduce failure rate: The smooth mold surface reduces failures caused by friction and wear, such as material jamming, mold breakage, etc., and improves the stability and continuity of production.
5. Reduce lubricant use
Reduce lubrication requirements: The high surface finish of the mold can reduce the use of lubricants during the stamping process, reduce production costs, and also reduce the pollution of lubricants to the environment.
Improve lubrication effect: Smooth mold surface can better distribute lubricant evenly, improve lubrication effect and reduce friction and wear.
6. Mold processing and maintenance
Mold processing technology: High-precision processing technology, such as grinding, polishing and EDM, is used to ensure a high finish on the mold surface. The processed mold surface also needs passivation and anti-rust treatment to prevent corrosion.
Regular maintenance: Regularly clean and polish the surface of the mold to maintain the smoothness of the mold surface and extend the service life of the mold.
Through the above technical measures and methods, Stamping Die surface finish plays a vital role in shaping high-quality stamping parts. It not only affects the surface quality, dimensional accuracy and production efficiency of stamping parts, but is also directly related to the service life and production cost of the mold.
