Geomembrane welding machine is an automated equipment specially used for welding various thermoplastic geomembrane materials such as HDPE, LDPE, PVC, EVA, etc. The equipment heats the membrane surface by hot wedge or hot air principle, so that two pieces of membrane material can be quickly fused under a certain pressure and speed to form a firm and reliable anti-seepage seam.

Product features and advantages
Intelligent constant temperature system: built-in temperature control chip, precise temperature control, avoid overheating and burning through the membrane material;
Reliable weld: forming a "double weld + cavity detection port" structure, which is convenient for inflation detection of air tightness;
Strong adaptability: can adapt to a variety of materials and different construction environments (plane, slope, corner);
Easy to operate: equipped with independent adjustment knobs for speed, temperature and pressure, easy to use and efficient;
Compact structure: small size is easy to carry and suitable for field construction;
Simple maintenance: key components can be quickly disassembled and assembled, easy for on-site maintenance and repair;
Support customization: high-power models, explosion-proof motors or shell spray colors can be customized according to user needs.
