Custom Metal Bending FAQ
What is the minimum bend radius you can achieve?
Minimum bend radius is typically equal to material thickness. For soft materials like aluminum, smaller radii are possible; for thick high-strength steel, larger radii are recommended to avoid cracking.
Do you provide hemming and edge folding for safety edges?
Yes, we offer closed hemming, open hemming and rope hemming for sheet metal edges to eliminate sharp edges and improve rigidity.
Can you bend thick steel plates over 10mm?
Yes, our 300T press brakes can bend steel plates up to 20mm thick within suitable length limits.
How do you control springback?
We use material-specific springback compensation parameters and in-process angle measurement to correct bend angles, ensuring consistent accuracy.
