Founded in 2000, Bohai has been dedicated to steel drum manufacturing industry for more than 20 years. With years of steel drum manufacturing, the steel drum production lines we produce can be in different types, including high speed automatic steel drum production line, medium speed automated steel drum production line, and low speed automated drum production line. And our metal drums can be of different series, such as closed head steel barrels, cone steel drum, open head barrel and bituminous steel barrel.

Moreover, Bohai also delivers professional manufacturing guidance thus to ensure the normal operation of steel drum production line.

Bohai offers semi-finished steel barrel parts of wide diversity for small-sized barrel making factories, including drum top cover, drum bottom. drum bung, drum bolt ring and drum body sheets. With these components, our clients could obtain finished barrels after further processing.

In virtue of dozens of years’ research, development and manufacturing, Bohai is fully qualified to deliver superior service, and manufacture top-class barrel production lines of customized capacities and types.

Steel drum pressing machine, as essential equipment in automatic steel barrel production line, is designed for the processing of drum bottom, drum top cover and steel drum plugs. The quality of pressing machine is directly related to the quality of finished steel drums. When there is an unstable operation or insufficient pressure, the drum top cover will possess unqualified shapes, which fails to fit the drum body.

When mould pressing, one process during steel drum production, is in operation, unstable manufacturing and low production efficiency may occur due to roughening, cracking, wrinkling and other phenomenon. In this case, following measures can be adopted to improve the mould pressing efficiency of 50-220L steel drum forming machinery:

• Moulds’ Cavity Circular Bead Polishing Treatment: When moulds undergo pressing process, moulds in barrel forming machine should be regularly cleaned and maintained, thus to remove the zinc and oil stains on the surface of moulds in steel rum production line. At the same time, checking the roughness of cavity circular bead is also required.
• Repair Welding of Cavity Circular Bead towards Petroleum Drum Production Line Moulds: When open head and closed head steel barrel manufacturing equipment is in operation, the phenomenon of severe local roughening, wrinkling and cracking occurs, which is mainly due to a decrease in hardness below 40HRC caused by the abrasion of extrusion part circular beads. In this case, repair welding can be adopted to the outworn parts.
• Chrome Plating towards Moulds of Barrel Making Equipment: Electroplating refers to the process of plating a thin layer of metal or alloy on certain metal surfaces to prevent metal oxidation, improve surface hardness and roughness.
• PPD Treatment towards Steel Barrel Making Equipment Moulds: For pressed moulds in steel drum production line, PPD (Pulsed Plasma Deposition) treatment, instead of electroplating, can be adopted to achieve maximum wear resistance effect.
