　　1. Product Overview & Core Technical Parameters

　　Our high-precision tolerance precision metal stamping parts are fabricated from high-quality metal materials through specialized precision stamping processes such as fine blanking, trimming, and coining. Equipped with high-rigidity precision CNC stamping machines and ultra-precision molds optimized for tight tolerance control, we overcome the challenges of ultra-small tolerance processing and ensure consistent high-precision manufacturing and efficient mass production. Below are the detailed technical parameters:

　　Material Options: Specialized for high-precision stamping - Austenitic stainless steel (304, 316L), alloy steel (40Cr, 42CrMo), high-purity copper (Cu-ETP), aluminum alloy (6061-T6, 7075), and precision alloy (Kovar, Inconel); Materials undergo strict ballization annealing treatment (for medium and high carbon steel) to ensure uniform microstructure (carbide spheroidization rate ≥90%) and excellent formability, avoiding dimensional deviation caused by material inhomogeneity during stamping

　　Precision Specifications: Ultra-high tolerance control - Dimensional tolerance: ±0.001mm ~ ±0.02mm (reaching ISO 6-9 grade, superior to ordinary stamping's ISO 11-13 grade); Key feature tolerance: ±0.0005mm for critical precision features; Surface roughness: Ra 0.025 ~ Ra 0.4μm (achieved by fine blanking and electropolishing); Flatness: ≤0.005mm/m; Parallelism: ≤0.01mm; Perpendicularity: ≤0.01mm; Hole position tolerance: ≤0.003mm, ensuring perfect fit with high-precision components

　　Stamping Processes: Advanced precision stamping technologies - Fine blanking (with V-ring pressure plate to achieve plastic shear deformation, avoiding fracture separation), trimming (removing rough edges to improve precision), coining (enhancing dimensional stability), progressive stamping with ultra-small step pitch; Adopting CAD/CAE simulation to optimize die structure and process parameters, controlling material flow and deformation; Implementing small clearance (0.001~0.005mm) or zero clearance design to ensure cutting precision; Equipped with special lubrication systems to reduce friction and avoid surface scratches

　　Product Dimensions: Thickness: 0.05mm ~ 8mm (covering ultra-thin to medium-gauge high-precision parts); Maximum length: 1500mm; Maximum width: 1200mm; Customizable according to customer drawings (supports complex micro-features such as micro-holes, fine grooves, and thin walls with high aspect ratio)

　　Surface Treatment: Precision-compatible processes - Electropolishing (reducing surface roughness to Ra 0.025μm and enhancing dimensional consistency), passivation (improving corrosion resistance without affecting precision), thin-film plating (nickel, chrome with thickness tolerance ±0.001mm), and vacuum coating; All treatments are strictly controlled to avoid dimensional deviation, ensuring the original high-precision tolerance is maintained

　　Mass Production Capacity: Daily output: 20,000 ~ 200,000 pieces (for high-precision tolerance parts); Lead time: 12 ~ 45 days for mass production (depending on tolerance requirements and part complexity); Equipped with automated precision feeding systems and online inspection stations to ensure stable production efficiency and consistent precision

　　Packaging Specifications: Precision-protective packaging - Anti-static film, vacuum packaging with desiccant, partitioned precision cartons, foam-lined wooden cases; Special anti-deformation packaging for ultra-thin high-precision parts to avoid dimensional changes during transportation; Labeling includes part number, material, tolerance grade, and batch information for full traceability

　　2. Core Advantages: Specialized for High-Precision Tolerance Stamping

　　2.1 Ultra-Precision Mold Design & Manufacturing

　　We adopt ultra-precision mold manufacturing technologies to ensure the foundation of high-tolerance control. Molds are processed with high-precision CNC machining centers and EDM (Electrical Discharge Machining), achieving mold accuracy of ±0.001mm. The die and punch edges are designed with micro-rounded corners (0.02~0.2mm) to inhibit shear crack generation and ensure smooth cutting surfaces. All molds undergo strict inspection and trial stamping verification, with dimensional deviations corrected through precision grinding to ensure that each mold can stably produce parts that meet ultra-high tolerance requirements. We also implement mold maintenance and calibration systems to maintain long-term mold precision stability.

　　2.2 Advanced Precision Stamping Process Control

　　We employ specialized precision stamping processes such as fine blanking to achieve ultra-high tolerance control. Unlike ordinary stamping that relies on shear fracture, fine blanking realizes plastic shear deformation by applying three-way pressure (V-ring pressure, punch pressure, and ejector pressure), resulting in parts with dimensional accuracy up to ISO 6 grade and surface roughness as low as Ra 0.025μm. We also adopt real-time process monitoring systems to track key parameters such as stamping force, feeding accuracy, and mold temperature during production, adjusting parameters in real time to avoid dimensional deviations caused by process fluctuations. Small clearance or zero clearance design between mold components further ensures cutting precision and reduces dimensional errors.

　　2.3 High-Quality Material Selection & Pretreatment

　　We strictly select high-quality metal materials from well-known suppliers, focusing on material purity, microstructure uniformity, and mechanical property stability—key factors affecting stamping precision. For medium and high carbon steel and alloy steel materials, we perform professional ballization annealing treatment to ensure carbide spheroidization rate ≥90% and uniform distribution, improving material formability and reducing dimensional deviation during stamping. All raw materials undergo strict incoming inspection, including material composition analysis, mechanical property testing, and surface quality inspection, to eliminate material defects that may affect precision and ensure the reliability of the base material for high-precision parts.

　　2.4 Full-Process Ultra-Precision Inspection & Quality Control

　　We establish a full-process quality control system tailored for high-precision tolerance parts, covering raw material procurement, mold trial, production process, and finished product inspection. The production process is equipped with online high-precision inspection equipment, including 3D coordinate measuring machines (accuracy ±0.0001mm), laser measuring instruments, and high-magnification optical comparators, to conduct 100% inspection on key dimensions and tolerance features of each part. For batch production, we implement statistical process control (SPC) to monitor dimensional stability and predict potential precision deviations. All finished parts must pass comprehensive inspection before leaving the factory, with a qualified rate of up to 99.95%.
