As a professional metal parts manufacturer established in 1996, Kailai Machinery have long been committed to precision processing services such as stamping, stretching, welding and surface treatment. In recent years, with the upgrading of manufacturing technology, stamping blanking and laser blanking have become the two mainstream processes for sheet metal processing. This article will compare the advantages and disadvantages of these two technologies in depth to help customers choose the metal manufacturing solution that best suits their needs.

1. Stamping Blanking: Traditional and Efficient Mass Production Solution

Stamping blanking is a classic metal processing method that directly punches out the desired shape by applying pressure to the metal sheet through the die. Its advantages include:

High production efficiency: Suitable for mass production, hundreds of stampings can be completed per minute.

Low cost advantage: Low unit cost, especially suitable for long-term stable orders.

High precision consistency: The die ensures stable product size and is suitable for standardized parts.

However, stamping blanking also has some limitations:

High mold dependence: Each product requires a customized mold, with high initial investment, and is not suitable for small batches or frequent model changes.

Limited material utilization: Complex shapes may lead to waste of scraps.

Lack of flexibility: Modifying product design requires re-opening the mold, which takes a long time.

2. Laser blanking: a modern solution without molds and high flexibility

Laser blanking uses high-energy laser beams to cut metal sheets without physical molds, which is particularly suitable for customized production. Its core advantages include:

Mold-free production: eliminating mold costs and shortening the new product development cycle.

High material utilization: Intelligent layout optimizes cutting paths, and material utilization can reach more than 90%.

Complex shape processing: It can cut high-precision curves, micropores and other geometric structures that are difficult to achieve with traditional stamping.

However, laser blanking also has certain challenges:

High initial equipment cost: Laser cutting machines have a large investment and are suitable for mid-to-high-end manufacturing needs.

Relatively slow speed: Although the technology has been improved in recent years (such as Honda's ILBS system can reach 120m/min), it is still not as good as high-speed stamping.

Heat-affected zone problem: The high temperature of the laser may affect the edge performance of some metal materials, such as generating burrs or internal stress.

3. How to choose? Our professional advice

As a metal manufacturing expert with nearly 30 years of experience, we recommend:

Large-scale standardized production → Stamping and blanking (low cost, high efficiency)

Small-scale customized needs → Laser blanking (no mold, high flexibility)

High-strength steel/aluminum alloy lightweight parts → Laser blanking (avoid stamping hardening problems)

We also provide integrated services for both processes, from metal stamping and stretching to laser precision cutting, to welding and surface treatment, to provide customers with one-stop metal parts manufacturing solutions.
