WHAT ARE YOU LOOKING FOR?
When working with thick sheet metal for pressure vessels, shipbuilding, or large steel structure projects, choosing the right plate rolling machine is crucial for achieving accurate cylindrical forms and maintaining high production efficiency. The selection process depends on several key technical and operational factors.
First, determine your maximum plate thickness, plate width, and minimum rolling diameter requirements. Three-roller rolling machines are the most common and versatile, suitable for most standard cylindrical forming applications. Four-roller models offer higher precision, faster setup, and easier operation, ideal for high-volume production and complex forming tasks.
Other important considerations include material type, yield strength, pre-bending capabilities, and CNC control options. Sanxin offers both three-roller and four-roller plate rolling machines designed for 2-60mm thick plate processing, with robust hydraulic drive systems, automatic pre-bending functions, and variable speed control. Our machines are widely used in shipbuilding, pressure vessel manufacturing, and steel structure industries, delivering reliable performance and consistent forming quality for even the most demanding heavy-duty applications.
Three-roller rolling machines are the most common and cost-effective, suitable for most standard cylindrical forming. Four-roller machines add a bottom roller for better material control, offering higher precision, faster setup, and the ability to do pre-bending on both ends without repositioning, ideal for high-volume production.
Minimum rolling diameter depends on plate thickness, width, and machine model. Generally, our three-roller machines can achieve minimum diameters of 1.5-2 times the top roller diameter. For example, a machine with a 200mm top roller can roll down to approximately 300-400mm diameter.
Yes, most of our rolling machines support cone rolling with optional cone rolling attachments. The operator adjusts the roller angles and positions to create the tapered shape. We provide specific guidance and training on cone rolling techniques for customers who need this capability.
Our rolling machines handle plates from 2mm up to 60mm thick, with rolling widths from 1000mm to 6000mm depending on the model. Heavy-duty models are available for shipbuilding, pressure vessel, and large steel structure applications. We'll help you select the right capacity based on your specific needs.
Pre-bending is the ability to bend the leading and trailing edges of the plate before rolling, eliminating the "flat ends" that occur with basic rolling. If you need complete cylinders with minimal flat sections, pre-bending is essential. Our higher-end machines include automatic pre-bending functions for more efficient and accurate forming.
