CX500L 220V 0.8–3mm Geomembrane Hot Wedge Welding Machine for Landfills and Fish Ponds

The CX500L is a dual-purpose welding machine that supports single-sided welding by feeding the geomembrane from the same side — typically used for capping biogas tanks and landfills. It also supports overlap welding, where the geomembrane can be fed from both the left and right sides. This versatile machine delivers a power output of 1800W and weighs just 9.5 kg.

A commercial tilapia farm in Kenya needed to line several large earthen ponds with HDPE geomembrane to prevent seepage and keep water levels stable. Local rainfall was unreliable, so any leak in the pond lining would directly waste water and raise production costs.

The farm chose the CANEX CX500L welder (1800W, dual-purpose model). Its copper hot wedge delivered consistent heat across thick HDPE sheets, producing double welds with an interior cavity that allowed on-site pressure testing to confirm every seam was watertight. The adjustable eccentric wheel matched the welding pressure to the film thickness, while the spring-loaded pressure wheel kept feeding steady over long pond edges.

Operators reported fast, uniform seams with minimal rework. The pond lining passed water-holding tests, kept stable water levels through dry seasons, and supported higher stocking density. For African aquaculture projects where durability and leak-proof performance matter, the CX500L proved to be a reliable, cost-effective solution.
