Industrial CNC Sheet Metal Bending & Precision Forming

The Filame Group provides high-precision industrial CNC bending using multi-axis Trumpf TruBend press brakes. We form custom sheet metal parts in steel, stainless steel, aluminium, and copper from prototypes to high-volume production, backed by optical angle monitoring and active springback compensation.

Industrial bending is a decisive manufacturing phase in precision sheet metal fabrication and mechanical assemblies. Equipped with modern multi-axis CNC press brakes up to 230 tons and 3,000 mm bed capacity, Filame guarantees reliable angular precision and consistent repeatability across diverse alloy grades.

Active Springback Compensation & Optical Laser Control

Sheet metal alloys exhibit distinct plastic deformation and elastic recovery. To eliminate angle discrepancies caused by rolling direction or raw sheet thickness tolerances, our press brakes feature:

• Automatically Controlled Bending (ACB Laser): In-process optical angle measurement corrects ram stroke dynamically, ensuring tolerance compliance from the very first part.
• Hydraulic CNC Dynamic Crowning: Real-time bed deflection compensation ensures consistent bend angles across the entire 3-meter working length.
• Specialized Tooling & Protective Films: Comprehensive inventory of hardened V-dies, goose-neck punches, and non-marking synthetic inserts for brushed stainless and aesthetic aluminum.

Processed Materials & Thickness Ranges

• Carbon & Structural Steels (S235, S355, DC01): 0.5 mm to 12 mm.
• Austenitic & High-Strength Stainless Steels (1.4301 / 304, 1.4404 / 316L, 1.4310): 0.5 mm to 8 mm with dedicated contamination-free tooling.
• Aluminium & Light Alloys (5000 & 6000 series): 0.5 mm to 15 mm with strict bend radius calculation to prevent micro-cracking.
• Copper & Brass: High-conductivity busbars and electrical connector enclosures.
