Geo hot wedge welder LST820

Short description:

The welding machine adopts a cash hot wedge structure, which is small in size and light in weight. Suitable for welding of all hot melt materials such as HDPE, LDPE, PVC, EVA, ECB, PP, etc. The products are used in tunnels, subways, water conservancy, agriculture, landfills, waterproof and seepage engineering, chemical mines, sewage treatment, roof construction, etc field.







Standard production

Full mold processing, high assembly accuracy, stable quality and long service life.

Control System

Advanced feedback type intelligent digital control system, high control precision and strong protection function.

Pressure regulation

The unique pressure adjustment mechanism can be fine-tuned according to the material and thickness of the membrane material to achieve the best welding effect.


Imported silicone pressure roller, good elasticity, high temperature resistance, strong wear resistance; special knurled steel pressure roller, non-slip, non-wearing, better welding effect of film material above 1mm.

Heating system

Special alloy wedge cutter with high-power heating tube, high heating efficiency and long service life
