Shop Floor Standard: 8× V-Groove Rule
We follow this scientific rule to ensure clean bending effects and avoid tool damage:
Thin sheet (under 3mm): V width = 6 × sheet thickness (for smaller fillets)
Medium sheet (3–8mm): V width = 8 × sheet thickness (universal standard for most bending scenarios)
Thick sheet (over 8mm): V width = 10–12 × sheet thickness (reduce bending force, prevent sheet cracking)
Full In-House Production & Strict Quality Control
Discover our raw engineering capability in this in-house production log. The video details our heavy-duty horizontal milling machine executing deep-groove precision profiling on a high-grade forged steel block. By managing the entire press brake tooling manufacturing process in-house—from initial metal milling to progressive CNC grinding—ALAS guarantees absolute linear straightness, structural integrity, and uniform hardness across full-length punch and die sections.
All processes are independently completed in our factory without outsourcing, ensuring stable quality and short lead time:
Design: AutoCAD, SolidWorks, UG/NX for standard and custom tooling design
Processing: CNC grinding, wire EDM, CNC milling, professional heat treatment
Heat Treatment: Quenching & tempering, induction hardening, nitriding
Inspection: CMM, optical comparator, hardness tester for 100% full inspection of dimension and hardness
Optional Surface Treatment: Nitriding, TiN coating, anti-rust oil treatment
Formal inspection reports can be provided for all orders upon request.
Global Machine Compatibility
We manufacture tooling in three mainstream global standards to adapt to different regional equipment:
European / Promecam Style: Matches Amada, Promecam, Durma for general sheet metal bending
New Standard / Wila Style: Matches Trumpf, Bystronic, Safan for high-precision automatic bending
American Style: Matches Cincinnati, Niagara for heavy-duty industrial bending
For unlisted machine brands or special models, you can provide machine parameters or tool drawings, and we will achieve 100% customized matching.

FAQ
Q: What is the 8× V-groove bending rule?
A: For 3–8mm medium sheet metal, adopt 8× thickness V width (most commonly used). For sheets under 3mm, use 6× thickness for smaller fillets. For sheets over 8mm, use 10–12× thickness to reduce bending force and prevent cracking.
Q: How to reduce springback when bending stainless steel?
A: Adopt over-bent punches. Use 85° punches for 90° stainless steel bending; 86°–88° punches for standard 90° mild steel bending.
Q: How to select the right punch shape?
A: Straight punches for conventional flat bending; sharp-angle punches for small-angle bending and springback compensation; gooseneck punches for U-channel and deep bending (anti-collision); radius punches for curved workpiece processing.
Q: How to avoid tool overload and damage?
A: Calculate bending tonnage scientifically based on sheet thickness, V width and material strength. Keep actual load 10–15% below the tool’s rated capacity. Use thickened or segmented tools for high-strength steel bending.
Q: Can you customize non-standard tool holders?
A: Yes. We customize non-standard clamping interfaces and tool holders for Amada, Promecam, Wila, Trumpf and other special equipment.
Q: What are the MOQ and lead time?
A: Standard tools: No MOQ. Custom tools: 1 set MOQ. Standard order lead time: 7–15 days. Custom order lead time: 20–30 days. Rush orders are acceptable for negotiation.
Q: Do you support international shipping?
A: Yes. We provide sea, air and express shipping services, covering North America, Europe, Southeast Asia, the Middle East, South America and other regions, with successful export experience to 40+ countries.
