Geomembrane Welding Machine LST800

Short Description:

The welding machine adopts the hot-wedge structure, which is small in size and light in weight. It is suitable for welding all hot-melt materials such as HDPE, LDPE, PVC, EVA, ECB, PP, etc. The product is used in tunnels, subways, water conservancy, farming, Waterproof and anti-seepage projects in landfills, chemical mining, sewage treatment, roof construction and other fields.

Small orders accepted.

To meet small batch customized services.

To meet the voltage requirements of 120V and 230V different countries and EU standard, US standard, UK standard plug requirements.

800W is the standard power, especially suitable for the welding of materials with the thickness of less than 0.8mm.

1100W is the strengthening power, especially suitable for the welding of materials with the thickness of more than 0.8mm. With the same welding quality, the speed is faster and the efficiency is higher.

The product is delivered with an additional maintenance spare parts package, including maintenance tools, Fuses, Spare Hot wedge and Press wheels.







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 Adjustment
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.

Pressure Roller
Imported silicone pressure roller, good elasticity, high temperature resistance, strong wear resistance; special knurled steel pressure roller, anti-slip, non-wear, better welding effect for membrane materials above 1mm.

Heating System
The special alloy wedge knife is matched with high-power heating tube, which has high heating efficiency and long service life.
