　　High Precision Deep Drawing Metal Stamping Die: Advanced Forming for Complex Components

　　Engineered to master the challenges of deep drawing processes, the High Precision Deep Drawing Metal Stamping Die integrates specialized structural design, premium material selection, and ultra-precision machining—delivering consistent, high-quality forming for complex, hollow metal components. Designed to handle deep drawing depths (up to 10x material thickness) while maintaining dimensional accuracy and uniform wall thickness, this die addresses key industry pain points such as material wrinkling, tearing, and springback, making it a critical tool for high-volume production across automotive, aerospace, electronics, and consumer goods sectors.

　　Core Technical Features

　　Premium Material & Wear-Resistant Construction

　　Crafted from high-performance alloys optimized for deep drawing’s high-pressure and abrasive conditions:

　　Base die material: High-grade DC53, SKD11, and Cr12MoV alloy steels with strict impurity control (≤0.003%), heat-treated to HRC 62-65 to ensure structural rigidity and resistance to deformation under extreme drawing forces (up to 200MPa).

　　Critical forming components: Tungsten carbide (WC-Co) inserts and powder metallurgy (PM) H13 steel for punch tips, die cavities, and blank holders—offering 3x higher wear resistance than standard steels, especially when processing high-strength materials (e.g., stainless steel, aluminum alloy, and carbon steel).

　　Anti-galling & low-friction enhancements: TiAlN/TiCN composite PVD coatings (friction coefficient ≤0.08) and mirror polishing (Ra ≤0.05μm) on forming surfaces eliminate material adhesion (galling) and reduce drawing resistance, ensuring smooth material flow and preserving component surface finish.

　　Corrosion protection: Passivation, black oxide, or electropolishing treatments (compliant with ASTM A967) for die components, safeguarding against humidity, coolants, and corrosive materials used in industrial production.

　　Deep Drawing-Optimized Structural Design

　　Tailored to minimize defects and maximize forming precision during deep drawing:

　　Adaptive blank holder system: Equipped with adjustable pressure pads (pressure range: 5-30MPa) and segmented design to distribute pressure evenly across the material surface, preventing wrinkling and ensuring uniform material flow into the die cavity.

　　Springback compensation technology: Pre-calculated geometric offsets (0.5-2.0°) and cavity profile adjustments integrated into the die design, counteracting material springback (common in deep drawing) to achieve final dimensional tolerance ±0.005-±0.01mm.

　　Smooth transition geometries: Die entry angles (15-30°) and radius-optimized forming edges (R=1-5mm, customizable by material thickness) reduce stress concentration, minimizing the risk of material tearing—even for deep drawing ratios (depth-to-diameter) up to 3:1.

　　Integrated lubrication channels: Precision-drilled channels deliver uniform lubrication (oil or dry film) to critical forming surfaces, reducing friction and heat generation while extending die life and improving component surface quality.

　　Ultra-Precision Machining & Dimensional Control

　　Manufactured using state-of-the-art machining technologies to meet the strict precision requirements of deep drawn components:

　　High-precision machining processes:

　　5-axis CNC milling with linear motors: Positional accuracy ±0.0008mm and surface finish Ra ≤0.08μm for complex die cavities (e.g., curved automotive housings, cylindrical electronic enclosures).

　　Slow wire EDM (SWEDM): Slit width tolerance ±0.001mm and edge sharpness ≤0.002mm, ensuring precise punch-die clearance (0.003-0.01mm) for uniform wall thickness (variation ≤0.01mm).

　　Precision grinding with CBN wheels: Flatness ≤0.001mm/m for die plates and parallelism ≤0.002mm for punch-die alignment, critical for consistent forming across high-volume runs.

　　High-precision guide system: Ceramic ball bearing guides with repeat positioning accuracy ≤0.001mm, maintaining alignment during high-speed stamping (up to 250 strokes per minute) and preventing misalignment-induced defects.

　　Advanced Heat Treatment for Stability & Durability

　　A multi-stage heat treatment process optimized for deep drawing die performance:

　　Vacuum quenching: Conducted at 1050-1100°C to ensure uniform hardness distribution, eliminating oxidation and internal defects.

　　Deep cryogenic treatment (-196°C): Reduces residual austenite to ≤5%, refines grain structure, and enhances dimensional stability—minimizing post-machining deformation by 90%.

　　Triple tempering (500-550°C): Balances hardness and toughness, improving fatigue resistance to endure over 50 million forming cycles for standard materials.

　　Key Performance Advantages

　　Complex Shape Forming Capability: Specialized structural design enables deep drawing of complex geometries (cylindrical, conical, rectangular, and irregular shapes) with high depth-to-thickness ratios, eliminating the need for multiple secondary processes.

　　Micron-Level Precision: Dimensional tolerance control (±0.005-±0.01mm) and uniform wall thickness (variation ≤0.01mm) ensure consistent component quality, reducing assembly fit issues and scrap rates to <0.5%.

　　Extended Service Life: Wear-resistant materials and anti-galling treatments enable 50+ million forming cycles, outperforming standard deep drawing dies by 2-3 times and lowering replacement costs.

　　Material Versatility: Compatible with a wide range of metals, including carbon steel (Q235, SPCC), stainless steel (304, 316L), aluminum alloy (5052, 6061), copper, and high-strength steel (up to 1200MPa), supporting diverse industry applications.

　　High Production Efficiency: Optimized material flow, integrated lubrication, and high-speed stamping compatibility (up to 250 strokes per minute) enable mass production of deep drawn components, meeting high-volume order demands.

　　Defect Reduction: Adaptive blank holder pressure, springback compensation, and smooth transition geometries minimize common deep drawing defects (wrinkling, tearing, necking, and springback), reducing post-processing requirements.

　　Application Scenarios

　　Automotive Industry: Deep drawing of fuel tanks, oil pans, transmission housings, door handles, and EV battery casings (stainless steel, aluminum alloy, and high-strength steel).

　　Aerospace & Defense: Forming of lightweight, high-strength components such as aircraft hydraulic system housings, drone fuel tanks, and missile casings (titanium alloy, aluminum-lithium alloy).

　　Electronics & Consumer Goods: Production of cylindrical battery enclosures, smartphone/tablet metal frames, camera lens housings, and audio device shells (aluminum alloy, stainless steel).

　　Home Appliances: Deep drawing of washing machine inner drums, refrigerator door liners, air conditioner compressor shells, and kitchenware (stainless steel, aluminum).

　　Medical Devices: Forming of precision medical component housings, surgical instrument handles, and implantable device casings (biocompatible stainless steel, titanium alloy).

　　Industrial & Packaging: Production of metal cans, pipes, valves, and hydraulic cylinder sleeves (carbon steel, stainless steel, copper).
