Manual or pneumatic folding is not enough for heavier work
When sheets are longer, folding is more frequent or the forming load increases, hydraulic drive is a more suitable basis for stable workshop production.

Customer Challenges
What Problems Can It Solve?
Start with sheet length, material, load and production frequency before choosing the drive system.
Long sheet edges need stable clamping
Hydraulic clamping helps reduce sheet movement during long-edge folding and repeated edge-forming work.
Workshops need consistent folding quality
The supported folding method suits repeated hems, duct-panel edges, sheet-metal wrapping and thin-sheet forming where stable results matter.
HVAC duct panels need efficient forming
Fold rectangular duct panels alongside cutting, beading, lock forming, flange forming and seam-closing operations.
Customers need a stronger machine without using a large press brake
For suitable thin-sheet long-edge work, a hydraulic folder offers a direct folding-beam process without automatically moving to a large press brake.

Real Industry Context
Applications
Real photographs show the industries, materials and downstream products supported by a suitable folding configuration.
HVAC duct panel folding
Forms suitable duct-panel edges before rectangular duct joining, flanging and assembly.
Rectangular air duct fabrication
Supports long straight folds used to prepare rectangular air-duct panels for the next forming stage.
Roofing sheet metal work
Useful for suitable roofing panels, flashing and trim parts that require long folded edges.
Architectural sheet metal
Supports cladding, edging and architectural parts where the selected model matches the material requirement.
Electrical cabinet and enclosure
Prepares long flanges and enclosure edges for suitable cabinet, chassis and door-panel production.
Stainless steel light fabrication

Long edge sheet metal bending
Hydraulic clamping and folding suit long workpieces that need stable support during edge forming.
General sheet metal workshop
A practical folding station for mixed daily work across suitable materials, lengths and production quantities.
Material Matching
Materials
Material strength matters as much as nominal thickness when the machine is selected.
Galvanized Sheet
Common for rectangular HVAC ducts and general workshop sheet-metal work.
Mild Steel Sheet
Suitable within the verified thickness and length of the selected HWS model.
Stainless Steel Sheet
Requires capacity confirmation because its material strength affects workable thickness.
Aluminum Sheet
Review alloy, thickness, bend radius and folding length before configuration.
Color Steel Sheet
Used in suitable roofing, enclosure and architectural trim applications.
Thin Metal Plate
Match material strength, folding length, angle and machine configuration together.
The suitable thickness depends on material strength, bending length, folding angle and machine configuration. Please confirm your material, thickness and bending requirement before quotation.
Power System
Hydraulic System for Stable Folding
Hydraulic drive is selected when the work calls for stronger clamping, longer supported parts or a more demanding production rhythm than lighter drive systems.
Stronger, stable clamping
Hydraulic power provides stronger and more stable clamping than purely manual operation for suitable longer or higher-load work.
Prepared for repeated production
The system is suited to longer sheet-metal parts and repeated workshop folding after the production requirement is confirmed.
Controlled clamping and folding movement
A hydraulic valve system controls the machine's clamping and folding sequence without unsupported pressure or pump claims.
Maintenance remains part of selection
Hydraulic oil condition, cooling requirements and routine inspection matter for dependable long-term operation.
Confirm the real production load
Before quotation, provide material, thickness, bending length, folding angle and daily production frequency.
Production Flow
From Flat Sheet to Folded Panel
A clear six-step sequence helps the folder fit into the surrounding fabrication process.
Sheet Cutting
Cut the sheet to the required size before folding.
Positioning
Position the sheet by flange size, duct-panel size or folding line.
Hydraulic Clamping
Use hydraulic force to secure the sheet before folding.
Hydraulic Folding
The folding beam completes the required edge-bending operation.
Angle Checking
Check the result and adjust it to the required part angle.
Next Process
Continue to locking, beading, flanging, riveting, welding, assembly or installation.
