Metal forming processes play a crucial role in the fabrication of various components. Two commonly used techniques are roll to plate and press brake. Join us as we delve into the world of roll to plate and press brake to understand their differences and determine the most suitable technique for your metal fabrication needs.
Roll to Plate: Principles and Process
Roll to plate, also known as plate rolling, is a technique that involves shaping flat metal plates into curved or cylindrical components using a plate rolling machine. The process typically utilizes three or four rolls, with the top roll exerting pressure on the plate while the bottom rolls support it. Roll to plate offers flexibility and precision in forming various curved shapes, making it ideal for applications such as pipes, tanks, and cylinders.
Press Brake: Principles and Process
Press brake, also referred to as brake press or bending brake, is a metal forming technique that utilizes a press brake machine. The process involves clamping a metal sheet between a punch and a die, then applying force to bend the sheet into the desired shape. Press brakes are available in different types, including mechanical, hydraulic, and servo-electric. Press brake techniques are versatile and suitable for forming a wide range of geometries, including V-bends, U-bends, and straight-line bends.
