Modification Of An Existing Metal Sheet-Bending Machine
The metal bending machine is designed to be manually operated. The bending machine with working capacity to complete a 900 fold of a full-length plate (8 ft = 2400mm) and up to 2.5mm thickness. The construction is based on initial machine design, materials. The machine can be used to perform any type of bending. It consist of heavy beams which are coupled together to bring about any shape of bending after the flat sheet has been marked out to specified dimensions. It serves as invaluable equipment because it offers solution to the technology of sheet metals in Nigeria.
