I. Core Processing Technologies: The Leap from Traditional to Intelligent
CNC Machining
Status: The “cornerstone” of precision metalworking, enabling high-precision automated production of complex parts through computer-programmed machine tools.
Applications: Machining cylindrical surfaces, tapered surfaces, and threads on components such as shafts, sleeves, and molds, with tolerances controllable within ±0.005mm.
Advantages: 300%-400% efficiency boost, ideal for mass production (e.g., automotive engine valve seats, transmission gears).
Stamping Forming Technology
Classification: Engineering mode (single-process stamping) and continuous mode (multi-process progressive dies).
Efficiency: High-speed continuous presses process 300-400 products per minute, ideal for sheet metal components (e.g., chassis housings, brackets).
Case Study: A Dongguan-based enterprise reduced gear blank processing time from 5 minutes to 8 seconds using multi-stage progressive dies.
Special Processing Technologies
Laser Cutting: Non-contact processing with minimal heat-affected zones, suitable for high-hardness materials like stainless steel and titanium alloys.
Electrical Discharge Machining (EDM): Corrodes metal through electrode discharges, enabling complex cavity machining (e.g., aircraft engine blades).
Five-Axis Machining: Boosts complex surface machining efficiency by 34%, widely used for medical implants and aerospace structural components.

II. Precision Machining Full Process: Stringent Control from Raw Materials to Finished Products
Drawing Analysis and Material Preparation
Standards: Conduct process feasibility analysis on customer-provided 2D drawings/3D models per ISO 9001 or IATF 16949 systems.
Material Cutting: Laser cutting, waterjet cutting, or sawing ensures blank dimensional accuracy of ±0.1mm.
Precision Forming Processes
Turning: X/Y-axis servo-driven carriage achieves coaxiality ≤0.01mm for long shaft components (e.g., drive shafts).
Milling: Five-axis machining centers achieve surface accuracy ±0.008mm for complex surfaces (e.g., turbine blades).
Drilling/Tapping: High-speed drilling/tapping centers achieve hole diameter accuracy of ±0.05mm and hole spacing tolerance of ±0.02mm.
Heat Treatment & Surface Finishing
Heat Treatment: Quenching (HRC 50-55) and carburizing (depth 0.5-1.2mm) enhance part hardness and wear resistance.
Surface Finishing:
Electroplating: Zinc plating (rust prevention), chrome plating (wear resistance), nickel plating (corrosion resistance), with thickness uniformity ±0.5μm.
Sandblasting/Polishing: Surface roughness below Ra0.4μm, meeting medical and aerospace requirements.
Anodizing: Forms an oxide film on aluminum alloy surfaces to enhance corrosion resistance and electrical insulation.
Quality Inspection & Assembly
Testing Equipment: Coordinate measuring machine (CMM), projector, height gauge for full-dimensional inspection.
Inspection Protocol: Initial inspection (100% full inspection), patrol inspection (once per hour), final inspection (sampling rate ≥20%).
Assembly: Utilizes error-proofing fixtures (e.g., locating pins, pneumatic clamps) to ensure component clearance ≤0.02mm.

III. Industry Applications: Comprehensive Coverage for High-Precision Demands
Medical Field
Products: Surgical instruments (e.g., bone drills, hemostatic forceps), implants (e.g., artificial joints, dental implants).
Requirements: Biocompatibility (ISO 10993), sterile processing (ethylene oxide sterilization or irradiation sterilization).
Aerospace Sector
Products: Titanium alloy structural components (e.g., landing gear), aluminum alloy parts (e.g., skin panels, stringers).
Requirements: Lightweight (density ≤4.5g/cm³), high strength (tensile strength ≥1000MPa).
Automotive Manufacturing
Products: Precision engine valve seats (clearance tolerance ±0.005mm), transmission gears (tooth profile accuracy Grade 7).
Trend: Surging demand for aluminum alloy components like motor housings and battery trays driven by new energy vehicle adoption.
Electronics Industry
