The quality and efficiency in parallel -mechanical pressure riveting and welding

Use the overall pressure riveting process (not play rivet process) for aluminum alloy frame and back plate , strengthening the four corners with aluminum soldering. The back plate is smooth, level off and has good sealing low heat loss, besides,no deformation under the 1000 kg dead load.

The quality and efficiency in parallel - Six sides has thermal insulation and laser welding

Our products adopt six surface heat insulation technology

The quality and efficiency in parallel- Ultra strong laser welding Absorer Technology

*Intensive laser welding plate;

*Unit length density affect the heat transfer performance of the solder joint.

**the industry of laser welds spacing is 5 mm more, ours is 2 mm;
