Quels sont les effets de la dureté des matériaux sur l'estampage des métaux?

Main Effect of Material Hardness on metal stamping

1.Mould wear rate

• High-hardness stamping metal (such as stainless steel and titanium alloys) accelerate mold wear, resulting in increased surface roughness (Ra value 0.5-1.0 μm).
• Alloy molds (such as tungsten steel) or surface coating techniques (such as TiN coating) are needed to extend service life.

2.Adjustment of stamping process parameters

• Harder materials require greater punching force (increasing the tonnage of the press by 20% to 30%) and lower punching speed to minimize the impact loss of the die.
• Low hardness materials (such as aluminum foil) is easy to wrinkle, need to adjust the edge pressure to increase the use of lubricating oil.

3.Quality of finished products and tolerance control

• When the hardness of stamping metal is greater than HRC 45, the tensile forming limit decreases decreases, cracks are easy to appear, and progressive stamping and additional annealing processes required.
• Low hardness materials suffer poor stability (±0.1mm fluctuation) and additional finishing processes are required to correct deformation.

4.Material Applicability Limitations

• Too much hardness (such as quenched steel) may cause mold blade breakage, so choose a composite mold structure (such as block mold).
• Ultra-low hardness materials (such as pure aluminum) require anti-adhesion treatment (such as nitrogenation of mold surfaces).

Comparison of stamping process of Different Hardness materials

• Material with high hardness: Priority should be given to alloy molds with slow stamping equipment (velocity ≤50spm) and annealing and softening should be added.
• Low hardness material: Optimize mold clearance (reduce by 5%-10%) and use polyurethane shock absorber to reduce rebound.
• General recommendation: Predicting process risk through material hardness testing (such as Rockwell hardness tester) and test pressure if necessary.

How to reduce the cost of metal stamping?

1.Improving accuracy and reducing waste

High-precision equipment and technology:

• Adopt ±0.005mm ultra precision machining technology (JS core technology) to reduce the scrap rate caused by size deviation and reduce secondary processing cost.
• The CAD/CAM system simulates stamping process, optimizes mold design and parameter setting in advance, and avoids material waste in actual production.

Automated production and intelligent detection: Automatic stamping equipment is combined with real-time quality control system to reduce manual intervention errors and improve yield rates.

2.Material management and selection strategy

Adaptability of a variety of materials: Use JS's metal material database of metal materials (such as stainless steel, aluminum alloy, copper alloy, etc.) to select the most cost-effective materials based on product performance and avoid overdesign.

Residual material recycling and nesting technology: Maximize board utilization (15%-20% increase in JS's material utilization rate) through intelligent typesetting algorithms, reduce corner material waste, and support the recycling of materials such as aluminum and steel.

3.Process efficiency and rapid response

Standardized and modular design: Provides a standardized metal punch library (connectors, casings, etc.) to shorten design lead times, and supports customers to customize quickly to existing templates to reduce development costs.

Agile production mode: Commit to 1-2 weeks of standard delivery time (including complex orders) and reduce additional costs for emergency orders through lean production management and priority scheduling.

4.Collaborative design and process collaboration

Early intervention in client design: The JS team provides pre-design review services to optimize the structural strength, tolerance fit, and assembly feasibility of metal punch to avoid additional costs associated with later modifications.

Mold sharing and lifecycle management: Provide long term maintenance and optimization services for high frequency order molds, extend the lifespan of molds (the average life of JS molds is 30% longer than industry standard), and dilute unit cost of individual products.

5.Sustainable production reduces costs and improves efficiency

Green manufacturing certification: Energy energy consumption has been reduced (JS energy consumption has been reduced by 15%) through the implementation of the ISO 14001 environmental management system and the introduction of energy-efficient stamping equipment and renewable lubricants.

Reduce process and logistics costs: Provide Design stamping surface processing one-stop service (JS integration capability covers the entire chain), eliminating intermediate costs.
