Comparison of metal identification technology: advantages, disadvantages and applications of laser marking, stamping marking and screen printing
As a professional metal manufacturing company established in 1996, we have long been committed to metal stamping, laser marking, welding and surface treatment processes. In the field of industrial identification, different marking technologies are suitable for different production needs. This article will deeply analyze the differences, advantages and applicable scenarios of the three mainstream identification technologies of laser marking, stamping marking and screen printing to help customers choose the best solution.
1. Laser marking: the first choice for high-precision and permanent identification
Laser marking uses high-energy laser beams to etch or oxidize the metal surface to form a permanent mark. This technology is widely used in electronics, automobiles, medical devices and other industries.
Advantages:
- Permanent: Laser marking is not easy to wear, fall off or tamper with, and is suitable for anti-counterfeiting traceability.
- High precision: micron-level characters can be engraved, suitable for fine PCB boards and precision parts.
- Environmentally friendly and safe: no chemical pollution, in line with the environmental protection standards of modern manufacturing industry.
- Flexibility: no mold is required, fast sample change is supported, and it is suitable for small batch customized production.
Applicable scenarios:
- Electronic components (PCB serial number, QR code)
- Medical equipment (stainless steel surgical tool marking)
- High-end automotive parts (VIN code, brand LOGO)
Limitations:
- The initial equipment cost is high, not suitable for ultra-low-cost mass production.

2. Metal stamping marking: efficient and durable industrial-grade identification
Metal stamping marking is a kind of metal stamping process, which uses a mold to stamp characters or patterns on the metal surface. This technology is particularly suitable for mass production needs such as automobiles and home appliances.
Advantages:
- High efficiency: A single stamping takes only a few seconds, which is much faster than laser or silk screen.
- High durability: The stamping depth is controllable, and the marking is wear-resistant and corrosion-resistant.
- Low cost (large batch): The unit cost is extremely low after the mold cost is diluted.
Applicable scenarios:
- Auto parts (chassis number, fastener marking)
- Home appliance metal parts (brand LOGO, production batch number)
- Industrial equipment nameplate (parameters, safety warnings)
Limitations:
- High mold cost, only suitable for long-term stable orders.
- Low flexibility, changing the mold requires changing the mark.
3. Screen printing: a low-cost but limited durability traditional solution
Screen printing forms a logo on the metal surface by leaking ink, which was once a traditional choice for the electronics and packaging industries.
Advantages:
- Low cost: low equipment investment, suitable for start-ups or small batch trial production.
- Fast marking: a single print can cover a large area, suitable for simple patterns.
Disadvantages:
- Easy to fall off: the ink is not resistant to friction and is easy to blur after long-term use.
- Environmental issues: ink containing heavy metals may pollute the environment.
- Limited accuracy: not suitable for fine text or high-resolution QR codes.
Applicable scenarios:
- Low-end electronic products (non-critical identification)
- Short-term promotional products (one-time packaging marking)
How to choose? Comparison of key factors
Factor | Laser marking | Stamping marking (Metal Stamping) | Screen printing |
Durability | Very high (permanent) | High (physical embossing) | Low (easy to fall off) |
Accuracy | Micron level | Medium-high (mold-dependent) | Low (ink diffusion) |
Cost (large batch) | Medium-high | Low (mold dilution) | Lowest |
Environmental protection | Best (no pollution) | Good (chemical-free) | Poor (toxic ink) |
Applicable materials | Metal/Plastic/Glass | Metal sheet (0.4-3mm) | Flat metal/plastic |
Recommended solution:
- High precision + anti-counterfeiting needs → Laser marking
- Large batch + low cost → Stamping marking
- Short-term/low-cost trial production → Screen printing
