HOW TO MANUFACTURE STEEL DRUM?

Steel drum manufacturing include this processes generally; basic forming, welding, coating and painting.

STEEL DRUM MANUFACTURING PROCESS

1. FORMING

Plastic forming method is used to steel drum production. Good quality and high strength work pieces are produced with plastic forming method. The method provides less material consumption and high productivity.

In plastic forming metals are shaped with exterior force. The method gives quality outputs and high performance.

Cutting processes include sheet metal cutting, drum lid punching, blanking and tapping. The process is same as the ordinary cutting process.

Roll forming process is special method for steel drum. It is only used steel drum body manufacturing. The steel body is hold on the mold, the roller bends and reinforce. W shape forming and curling.

2. WELDING

The drum body is welded with seam welding machine. The seam welding is continuous welding. This method uses electrode wheels. Seam welding produces a weld at the faying surfaces of two similar metals. It is mostly an automatic process. The electrodes are often disc shapes and rotate as the material passes between them. The electrodes can move materials.

Joint of the material is heated to its melting point by current. The semi-molten surfaces are pressed by the welding pressure and resulting in a uniformly welded structure. Seam welder machines mostly use water cooling.

Seam welding produces an extremely durable weld.

Seam welding machines use to steel drum body manufacturing.

3. COATING AND PAINTING

Coating and painting process are done after the formation steel drums. The main purposes of the processes are aesthetic and to provide resistance to corrosion. Cleaning operation is in on coating process. Forming and welding processes must be finished to start coating and painting.

The drums are rotated in the painting booth in horizontal position during spraying. The drums are passed through a flash off unit and the curing oven that is designed for a drying time and temperature of tender document. The drums are passed through a flash off unit and the curing oven that is designed for a drying time and temperature of tender document. Drums are transported with conveyors. After completed the steel drum is moistened, dried and printed.

Letter/number characters indicating type, code and batch number can printed by inkjet printer according to manufacturer’s request.
