Badge production volume
Small batch production: For small batch production of badges, you can choose lower-cost die steel materials, such as Cr12, which has better wear resistance and certain strength, can meet the requirements of small batch stamping, and the price is relatively close to the people, can effectively control costs.
Mass production: In the case of mass production, the mold needs to have higher wear resistance, strength and toughness to ensure that the mold maintains good performance during a long time and high frequency stamping process. At this time, you can choose high-performance die steel, such as DC53 or SKD11. The toughness and wear resistance of DC53 are better than that of Cr12, which can reduce the wear and fracture of the mold and improve the production efficiency and the life of the mold in mass stamping. SKD11 has higher hardness and wear resistance, suitable for badge stamping with higher hardness requirements.
The material properties of the badge
Soft metal badge: If the badge is made of soft metals such as aluminum and copper, the hardness of the mold material is relatively low, but it needs better toughness and anti-stick performance. P20 steel can be selected, which has good polishing performance and certain toughness, and can effectively prevent soft metal from sticking to the mold during the stamping process to ensure the surface quality of the badge.
Hard metal badges: For hard metal badges such as stainless steel, the mold needs to have higher hardness and strength to resist pressure and wear during stamping. H13 steel can be used, which has good thermal strength, thermal fatigue and certain wear resistance, and can withstand the high temperature and high pressure generated when stamping hard metal, reducing the deformation and wear of the mold.
The shape and complexity of the badge
Simple shape badges: For badges with simple shapes and symmetrical structures, such as round, square, etc., the requirements for mold materials mainly focus on wear resistance and hardness. General die steel such as Cr12MoV can meet the requirements, it has higher hardness and better wear resistance, can ensure the service life of the mold when stamping simple shape badges.
Complex shape badge: When the badge shape is complex, with fine patterns and convex and convex structure, the stress distribution of the mold is not uniform during the stamping process, and the mold material needs to have better toughness and fatigue resistance to prevent the mold from cracking and damage under the complex stress. At this time, you can consider the selection of 8407 steel, which has good toughness, thermal fatigue and processing performance, can better adapt to the stamping needs of complex shape badges, and ensure the life of the mold and the molding quality of the badges.
Cost factor
Material cost: The price of different mold materials varies greatly, and the production cost needs to be considered comprehensively when selecting. For a limited budget, you can give priority to materials with a relatively low price but performance that can meet basic requirements, such as the Cr12 mentioned earlier. For projects with high requirements for badge quality and mold life and sufficient budget, you can choose materials with better performance but higher prices, such as DC53, SKD11 and so on.
Service life cost: Although some high-performance mold materials are more expensive, due to their longer service life and better performance, in mass production, the total production cost may be reduced in the long run. For example, the mold made of SKD11 die steel, although the procurement cost is higher, it can withstand more stamping cycles, reducing the frequency of mold replacement and maintenance, thereby reducing the production loss and maintenance costs caused by downtime to replace the mold.
processability
Machinability: The mold material needs to be machined to produce an accurate mold shape, so machinability is an important consideration. A material with good machinability, such as P20 steel, can more easily achieve the required dimensional accuracy and surface quality during processing, reducing the difficulty and cost of processing.
Heat treatment performance: The mold usually needs heat treatment to improve its performance in the manufacturing process, such as quenching, tempering, etc. The selection of materials with good heat treatment properties can ensure that the mold obtains stable structure and properties after heat treatment, reducing the risk of deformation and cracking. For example, after appropriate heat treatment, H13 steel can obtain good strength, toughness and thermal stability to meet the requirements of the use of stamping dies.
