Stamping parts are workpieces of desired shape and size produced by applying pressure to metal sheets, strips, or other materials using a press and dies, causing plastic deformation or separation. This process is primarily carried out at room temperature and falls under the category of cold stamping, offering advantages such as high efficiency, high precision, low cost, and mass production.
Core Characteristics of Stamped Parts:
High-Efficiency Production: Hundreds of parts can be produced per minute, suitable for large-scale manufacturing.
High Precision and Consistency: Dies ensure accurate part dimensions, good repeatability, and strong interchangeability.
High Material Utilization: Production can achieve low or even zero waste.
Lightweight and High-Strength Combination: Parts with reinforcing ribs, flanges, and other structures can be manufactured, increasing rigidity while maintaining lightness.
Main Application Areas:
Automotive Manufacturing: Each passenger car contains 1200–1500 stamped parts, covering body panels (such as doors and hoods), structural components (such as longitudinal beams and floor assemblies), and engine system components. The Chinese passenger vehicle metal stamping parts market reached 234.071 billion yuan in 2022.
Home Appliances & Electronics: Refrigerators, air conditioner housings, microwave oven door frames, and heat sinks for electronic devices all utilize stamping processes.
Architectural Hardware: Includes door locks, hinges, pipe fittings, and metal ceilings.
Aerospace & Medical Equipment: Used to manufacture high-precision, high-strength key components.
Common Materials:
Steel (72%–88%)
Stainless Steel (e.g., 304 stainless steel)
Aluminum and Aluminum Alloys (used for lightweighting requirements)
Process Classification:
Separation Processes: Such as blanking, punching, and trimming, used to cut materials to form contours.
Forming Processes: Such as bending, deep drawing, and flanging, used to change the shape of materials without breaking.
