JM Laser is committed to providing comprehensive equipment and processing solutions for hermetic sealing of metal enclosures. This includes customized equipment for seal welding, non-destructive marking, precision cutting, and hermeticity testing, along with raw material sourcing and custom fabrication services for metal enclosures.
According to the materials and characteristics of the product, different degrees of environmental protection are required during laser welding. Therefore, we have developed multiple laser sealing welding equipment to meet the diverse needs.
For example, if the product needs to ensure that the interior is in a vacuum environment after welding, we recommend using a vacuum laser welding system to complete it.

The quality of metal raw materials is a key factor affecting packaging performance. The use of raw materials with low quality, uneven composition, lower than standard content, or inconsistent quality between batches may result in packaging effects that cannot meet product design standards. We are committed to providing high-quality and stable metal materials to ensure packaging effects meet and exceed customer expectations.
The shell material is 6061 aluminum alloy, and the cover plate material is 4047 aluminum alloy. The left weld seam was welded using the customer’s original material, resulting in severe cracks. The 4047 aluminum alloy we provided on the right side can complete normal laser hermetic sealing welding.
We provide metal packaging shell processing services, providing metal shell products for many fields such as aerospace, military weapons, shipbuilding, communication equipment, etc.
Using the ASTM F2096 immersion method, macroscopic defects greater than 5 × 10 ⁻⁵ Pa · m ³/s are accurately captured using high-density fluorine oil (density 1.85g/cm ³):
Equipped with a customized helium mass spectrometer leak detection system (detection lower limit 5 × 10 ⁻⁸ Pa · m ³/s), strictly following:
Provide precise opening equipment for metal shell laser sealing and welding. After opening, the cover plate can be replaced for re sealing and welding. It adopts a dry, stress free, and non-destructive flexible processing technology that does not require chemical etching. It is clean and environmentally friendly, suitable for two-dimensional and three-dimensional contour processing, and improves work efficiency.
In the full lifecycle management of precision components, we use laser surface modification technology to achieve permanent marking with zero thermal damage. By precisely controlling the laser pulse energy, permanent irreversible marks can be formed on the surface of materials such as titanium alloys and Kovar alloys
