Multi-cavity metal stamping die for hardware products

　　Multi-Cavity Metal Stamping Die for Hardware Products: High-Efficiency Mass Production Solution

　　Engineered to maximize output for standard and custom hardware manufacturing, the Multi-Cavity Metal Stamping Die integrates optimized multi-cavity design, wear-resistant materials, and precision engineering—delivering consistent quality, accelerated production rates, and cost savings for high-volume hardware production. Tailored for stamping small to medium-sized hardware components, this die enables simultaneous forming of multiple parts in a single stroke, making it the preferred choice for hardware manufacturers seeking to scale operations without compromising on precision.

　　Core Technical Features

　　Optimized Multi-Cavity Design & Layout

　　Featuring 2-32 cavity configurations (customizable based on part size and production demand), the die is engineered to maximize material utilization and stamping efficiency. Key design highlights:

　　Uniform cavity distribution: Symmetrical or staggered layout ensures equal pressure distribution across all cavities, preventing part deformation and ensuring consistent dimensional accuracy.

　　Modular cavity inserts: Removable, interchangeable cavity inserts allow quick switching between part designs (e.g., different screw sizes, bolt heads) without replacing the entire die, reducing downtime for product line changes.

　　Synchronized forming technology: Precision-aligned punches and die cavities enable simultaneous stamping, blanking, bending, or piercing of multiple parts—cutting production time per unit by 50-80% compared to single-cavity dies.

　　Material optimization: Nesting design minimizes scrap by maximizing sheet metal usage (material utilization rate ≥90% for standard hardware), lowering raw material costs.

　　Premium Wear-Resistant Materials

　　Crafted from high-performance alloys and enhanced with surface treatments to withstand the abrasive nature of hardware stamping (e.g., carbon steel, stainless steel, aluminum):

　　Base die material: High-grade SKD11, DC53, or Cr12MoV alloy steel with HRC 60-64 hardness, ensuring structural rigidity and resistance to high stamping stress.

　　Cavity inserts: Tungsten carbide (WC) or powder metallurgy (PM) steel for critical wear areas, extending die life by 2-3 times when stamping high-strength hardware materials.

　　Surface enhancements: Gas nitriding, TiAlN PVD coating, or TD coating reduces friction coefficient (≤0.18) and prevents metal adhesion (galling), critical for stamping threaded or textured hardware components.

　　Precision Machining & Dimensional Control

　　Manufactured using advanced machining technologies to ensure uniform performance across all cavities:

　　CNC milling & EDM: 5-axis CNC milling achieves cavity dimensional tolerance ±0.01mm, while wire EDM ensures consistent punch-die clearance (0.005-0.02mm) for all cavities.

　　Precision grinding: Flatness ≤0.002mm/m for die plates and parallelism ≤0.003mm for punch sets, guaranteeing uniform material flow and part consistency.

　　High-precision guide system: Ball bearing guide pillars with repeat positioning accuracy ≤0.002mm maintain alignment across thousands of stamping cycles, preventing cavity misalignment.

　　Durability-Enhanced Heat Treatment

　　A specialized heat treatment process ensures long-term stability and wear resistance:

　　Vacuum quenching: Eliminates oxidation and ensures uniform hardness distribution across the die body and cavity inserts.

　　Deep cryogenic treatment (-196°C): Reduces residual stress and deformation, enhancing dimensional stability for multi-cavity consistency.

　　Tempering at controlled temperatures: Balances hardness and toughness, enabling the die to withstand over 50 million stamping cycles for standard hardware materials.

　　Practical Production-Centric Features

　　Integrated scrap management: Built-in chip channels and stripper plates efficiently remove scrap and finished parts, preventing jams and ensuring continuous production.

　　Quick-change design: Modular punch and cavity inserts enable tooling adjustments in 30 minutes or less, supporting flexible production of mixed hardware batches.

　　Compatibility with standard presses: Designed to fit most mechanical or hydraulic stamping presses (tonnage range: 10-200T), ensuring seamless integration into existing production lines.

　　Key Performance Advantages

　　Mass Production Efficiency: Multi-cavity design delivers 3-8x higher output than single-cavity dies (e.g., 16-cavity die produces 16 screws per stroke), meeting high-volume order demands.

　　Consistent Part Quality: Uniform cavity design and precision machining ensure dimensional consistency across all parts (tolerance ±0.01-±0.03mm), reducing scrap rates to <1%.

　　Cost Savings: Higher production efficiency, reduced material waste, and extended die life lower the total cost of ownership (TCO) by 30-40% for mass-produced hardware.

　　Flexible Customization: Modular cavity inserts support quick switching between part sizes, shapes, or functions (e.g., bolts, nuts, washers, brackets), adapting to diverse hardware product lines.

　　Low Maintenance: Wear-resistant materials and modular design simplify inspection, repair, and replacement of components, minimizing production downtime.

　　Compliance & Traceability: Manufactured to ISO 9001 standards, with full documentation (material certificates, heat treatment records, inspection reports) for quality traceability.

　　Application Scenarios

　　Designed exclusively for hardware mass production, this multi-cavity stamping die is widely used in:

　　Fastener Manufacturing: Stamping of screws, nuts, bolts, washers, rivets, and anchors (carbon steel, stainless steel, or aluminum materials).

　　Furniture Hardware: Production of drawer slides, hinges, handles, brackets, and decorative hardware components.

　　Electronic Hardware: Stamping of terminal blocks, connector shells, heat sinks, and mounting brackets for consumer electronics and industrial controls.

　　Building & Construction Hardware: Manufacturing of nails, staples, pipe clamps, curtain rods, and structural brackets.

　　Automotive Hardware: Production of small automotive hardware (e.g., clips, fasteners, washers) for vehicle assemblies.

　　Daily-Use Hardware: Stamping of kitchenware accessories, tool bits, key blanks, and hardware for home appliances.
