Contract HDPE Hot Wedge Welding Machine PFE-GM1

• Compact hot wedge welding.

This welding machine adopts advanced thermal braiding structure, which is smaller in size, lighter in weight and larger in power. It is suitable for welding various hot film materials of 0.2 to 2.0 mm. It has two-way film forming and one-way same side film forming machines. The product is suitable for the construction of anti-seepage projects in tunnels, subways, water conservancy, aquaculture, ponds, landfills, chemical mines, etc., sewage treatment, roof waterproofing and other fields.

• Meet the voltage requirements of 120V and 230V in different countries and the plug requirements of EU standards, American standards, and British standards.

• Accept small orders.

• Satisfy small batch customization services.

This machine can not only display the welding temperature and welding speed, the control system adopts closed-loop control, regardless of the external voltage change, or the welding direction up or down under the change of the external environment, such as negative feedback automatically adjusts the set temperature and speed to make welding The parameters are more stable and the welding quality is more reliable.

Categories: ,


Products of the same level are light in weight, small in size and high in welding efficiency.

Dual LCD displays welding temperature and welding speed.

Closed loop control system

The newly developed wedges have higher heating efficiency and longer service life.
