Automatic HDPE Geomembrane Welding Machine

Geo-membrane welder is a new welding machine which is developed by our company. They can weld geo-membrane of various thickness and are applicable for welding of all thermal-fused material such as LDPE, PVC, HDPE, EVA, PP and PVC,HDPE,EVA,PP The control of this series adopt PID automatic thermostatic control with high control and ow temperature fluctuation. Speed control of this series adopt PWM automatic voltage and regulation speed circuit.


Direct current servo the motor drive with great output torque and staple performance in walking. It can maintain a constant speed on the condition of creeping, vertical creeping and road load. Also this series of welding machine are stable in performance despite of external temperature and voltage variation. This series of welding machine is excellent in performance and easy for operating, with high welding speed and good work quality. It is extensively used in engineering projects such as expressways, tunnels, reservoirs, waterproof of construction and so on.


We always provide high quality products and workable price for every clients and have won the trust and approval.

Machine Quality Guarantee: 24 months.--If any parts broken or does not work under normal operating, we provide them for free.



Please clean the dunghill in the thermal wedge and the mud in the chain guard and oiled the whole machine to the dry place when not using it.

Weldy hot air blower HT 1600 costs about 190-250 USD/set.

What is Weldy booster EX3?

The Weldy booster EX3 extrusion welder is used for high-quality processing of polyolefins and thermoplastics PE and PP. In contrast to the short and compact booster EX2, the booster EX3 with its maximum output of 3.4 kg/h/7.5 lbs/h is ideal for work that requires a lot of standing.
