4100 Hydraulic Folder Machine Ideal for Bending Aluminum Steel Stainless Sheets

In the field of sheet metal processing, bending is one of the most frequently used forming processes. A reliable bending machine is the core equipment of a production line, whether it is the edging and sealing of building curtain walls, the flange production of ventilation ducts, or the sheet metal forming of chassis and cabinets. The 4100 Hydraulic Folder Machine, with its 4100mm bending length and hydraulic drive system, is designed specifically for the bending of medium thick plates of aluminum, steel, and stainless steel plates, helping metal processing enterprises achieve high-precision and high-efficiency mass production.

Core Advantages：

1. All steel welded structure, strong rigidity and stable precision
The equipment adopts a fully welded steel frame structure, which has undergone vibration aging treatment to eliminate internal stress and has sufficient strength and rigidity. Combined with the mechanical limit block and torque shaft forced synchronization mechanism, the slider runs stably and reliably, ensuring consistent bending angles and repeated positioning accuracy. The hydraulic drive system enables the two end oil cylinders to directly drive the slider to work, with fast response and stable pressure.

2. 4100mm bending length, suitable for various types of boards
The effective bending length of 4100mm can meet the processing needs of the vast majority of metal sheets, whether it is standard specifications of aluminum veneer, galvanized steel sheet, or stainless steel sheet, all of which can be bent and formed in one go. The equipment supports the processing of various metal materials such as copper, aluminum, alloys, carbon steel, stainless steel, etc. Combined with different upper and lower molds, composite processes such as punching and pressing can also be completed.

3. Hydraulic drive system with abundant power
The hydraulic system is equipped with imported hydraulic components (optional German Rexroth or American OMG brand), coupled with a low-noise internal gear pump, providing stable and long-lasting bending power. The hydraulic drive method ensures a smooth and impact free bending process, effectively protecting the surface coating of the board and reducing bending patterns.

4. Wedge type deflection compensation for higher bending accuracy
To address the pain point of deflection deformation in the middle area during the bending of long sheets, the equipment is equipped with a wedge type deflection compensation mechanism, which can effectively eliminate the angle deviation during the bending process and ensure the consistency of the bending angle throughout the entire length range. This design significantly improves the bending accuracy of 4100mm long panels, making it particularly suitable for building panels and curtain wall processing that require high bending straightness.

5. Intelligent control, easy to operate
The equipment can be equipped with a CNC numerical control system, which supports angle programming and automatic compensation functions. The grating ruler provides real-time detection feedback, replication correction, and achieves full closed-loop control. The positioning accuracy of the slider can reach ± 0.02mm. The operator can set the bending angle, rear stop position, and bending sequence through the touch screen, supporting multi-step programming and completing multiple bending processes in one clamping, greatly improving production efficiency.

Frequently Asked Questions (FAQ)：

Q1: How thick plates can this bending machine process?

The bending thickness depends on the material type and bending length. For example, when bending carbon steel with a total length of 4100mm, the typical processing thickness is 1-2mm; when bending narrower plates, thicker materials can be processed. Please confirm the machinable thickness of aluminum plate and stainless steel according to the specific material and mold configuration.

Q2: Can the equipment bend aluminum plates and stainless steel?

Okay. The equipment is suitable for various metal materials such as copper, aluminum, alloys, carbon steel, stainless steel, etc. For stainless steel materials, it is recommended to use molds that have undergone quenching treatment to ensure bending quality and mold life.

Q3: What is the bending accuracy that can be achieved?

When using CNC control configuration, the positioning accuracy of the slider can reach ± 0.02mm, and the repeated positioning accuracy can be ± 0.01mm. With the help of a wedge type deflection compensation mechanism, the consistency of the bending angle of the entire length of the long plate can be effectively guaranteed.

Q4: Does the device support customized voltage?

Support. The equipment can be customized with voltage configurations according to the power grid standards of the customer's country, supporting different voltages such as 220V, 380V, 415V, 440V, etc. The frequency can be selected as 50Hz or 60Hz.
