How does Manhart (Guangdong) CNC Machine Tool Co., Ltd. consider material selection in the design of bending machine molds?

The selection of materials is crucial in the design of bending machine molds, as it directly affects the performance, service life, and cost of the molds. Here are some key points to consider when designing a bending machine mold for material selection:
1. * * Hardness * *:
-The mold material needs to have sufficient hardness to withstand the pressure and friction generated during the bending process.
-High hardness materials can better maintain the shape and dimensional accuracy of molds, and improve the qualification rate of products.
2. * * Wear resistance * *:
-During the working process, the mold will continuously rub against the workpiece, so it is necessary to choose materials with good wear resistance.
-High wear-resistant materials can extend the service life of molds and reduce the frequency of mold replacement.
3. * * Resilience * *:
-The mold needs to have a certain degree of toughness when subjected to pressure and impact to prevent fracture or damage.
-Materials with good toughness can better adapt to the stress and deformation generated during the working process.
4. * * Heat treatment performance * *:
-Some materials can improve their hardness, wear resistance, and toughness through heat treatment.
-When selecting materials, it is necessary to consider their heat treatment performance and the performance changes after heat treatment.
5. * * Cost * *:
-The cost of different materials varies greatly, and it is necessary to choose appropriate materials based on the production scale and market demand of the product.
-On the premise of ensuring performance, try to choose materials with lower costs to reduce production costs.
6. * * Processability * *:
-Choosing materials that are easy to process and cut can reduce the difficulty and cost of mold processing.
-Consider factors such as cutting speed, cutting force, and tool wear to select the most suitable material.
7. * * Corrosion resistance * *:
-Select materials with corrosion resistance based on the working environment and usage scenarios to prevent mold damage caused by corrosion during use.
8. * * Environmental friendliness * *:
-When selecting materials, considering their environmental friendliness, choosing non-toxic, harmless, and recyclable materials is beneficial for sustainable development.
In summary, in the design of bending machine molds, the selection of materials needs to comprehensively consider factors such as hardness, wear resistance, toughness, heat treatment performance, cost, machinability, corrosion resistance, and environmental protection. Through reasonable material selection, high-performance and cost-effective bending machine molds can be designed to improve product quality and production efficiency.
