Rolling Process: The machine uses a series of rollers to bend and shape the steel strips into the U-shaped or C-shaped profile that makes up the door frame. 2. Adaptability: The machine is often adjustable to accommodate different sizes and types of door frames, allowing for versatility in production. 3. Automation: Modern machines can be automated to increase production efficiency and reduce labor costs. They can be programmed to produce frames of consistent size and shape.
