Precision 140mm Aluminum Profile Corner Crimping Machine

• Adjustable combining parameters: Combining pressure, tool stroke, and working position can be set to match the profile cross-section. This allows the 140mm Aluminum Profile Corner Combining Machine to work with various aluminum and thermal break profiles within the 140 mm width range without extensive changeover.
• Welded steel frame: The main structure is fabricated from thickened steel plate and welded into a single unit. This construction resists the vibration and reaction forces generated during the combining cycle, so the machine maintains alignment during extended runs and 24-hour operation.
• Operator safety and controls: A guarding system with an anti-misoperation interlock prevents the combining cycle from starting while the operator's hands are in the work zone. The pneumatic clamping and combining sequence is controlled by push buttons, with no programming required. Most new operators can learn the loading and cycle-start routine after a short demonstration.

 

Key Features

140mm Large Capacity – Handles wider and thicker aluminum profiles beyond standard 120mm machines.

High Crimping Force (48 kN) – Hydraulic power ensures tight, permanent corner joints without gaps.

Precision Positioning System – Hardened locating blocks guarantee ±0.1 mm repeatability for perfect 90° corners.

Heavy-Duty Frame – Stress-relieved welded steel structure minimizes deflection and extends machine life.

Pneumatic Clamping – Secure, fast-acting clamps hold profiles firmly during crimping.

Adjustable Crimping Depth – Easily adapts to different profile geometries and corner key designs.

User-Friendly HMI – Intuitive button or PLC interface reduces training time and operator fatigue.

CE Safety Compliance – Full guarding, dual-hand operation, and safety interlocks protect operators.

:How It Works

Load Profile & Corner Key – Place the profile and corner key into the hardened locating block.

Pneumatic Clamping – Fast-acting clamps secure the profile firmly in place.

Hydraulic Crimping – High-pressure crimping head locks the corner with 48 kN force.

Precision Forming – Profile corners are formed to a perfect 90° angle with no gaps.

Automatic Release – Clamps release, and the finished profile is ready for removal.

FAQ

Q1: What profiles can this machine crimp?

A: It is designed for aluminum window, door, and curtain wall profiles up to 140 × 140 mm. Custom models are available for larger profiles.

Q2: Is the crimping force adjustable?

A: Yes. The hydraulic system allows for crimping force adjustment to match different profile thicknesses and corner key types.

Q3: Does it support angles other than 90°?

A: Standard models are fixed at 90°. Custom models with adjustable angles (e.g., 45°) are available upon request.

Q4: What is the typical crimping accuracy?

A: Positioning accuracy is ±0.1 mm, ensuring consistent, high-quality corner joints.
