Electric water heater inner tank welding line, Heat pump water heater inner tank welding line, Water storage gas water heater inner tank welding line, Boiler inner tank welding line, Enamel water heater inner tank welding line, Stainless water heater steel inner tank welding line, Water uffer tank welding line - whatever you call it. The production line is customized according to client capacity requirements, either fully-automatic or semi-automatic.

Planishing machine is employed to remove weld build-up. This results in a flush, smooth weld.Planishing is a quick and inexpensive means for removing weld build-up and improving surface finish. The planishing operation improves the grain structure of the weld causing an increase in tensile fatigue strength up to 100% of the parent metal.Various part shapes can be accommodated through the design of the planish roll and mandrel insert. Part shapes include flat sheet, ylinders, cones, and sinks.

The cylinder can be flared or necked, for the insertion of end caps;Cylinder length changeover is driven by AC servo motor + ball screw, and the lifting of flared wheel is driven by AC servo motor + ball screw.Diameter: 150–600mm; Cylinder length: 300-1800mm; Material thickness: 0.8-3.0mm.

Inner tank clench machine, Inner tank coupling machine, Inner tank assembly machine - whatever you call it. The clenched cylinder and end cap are tightly connected without gaps, and the end cap will not fall off; The inner surface of the clenched inner tank is smooth, which is conducive to enamel.
There are 2 types of structures for clench machine:
■ Pressure wheel clench (Inner tank rotation);
■ Mold mechanical clench (Inner tank does not rotate).
Suitable for 2 types of inner tanks: Plus-plus inner tanks and Plus-minus inner tanks;
■ The cylinder is automatically loaded/unloaded;
■ The end cover can be loaded automatically or manually;
■ Automatically coupled and Clenched;
■ Diameter: 150–600mm; Cylinder length: 300-1800mm; Material thickness: 0.8-3.0mm.
