4 Way Press Brake Die High Strength Multiple V Openings

Technical Specifications & Material Engineering

Are your bottom dies wearing down prematurely or leaving unwanted marks on stainless steel and aluminum sheets? We engineer every 4 way press brake die to deliver long-term durability and extreme precision under heavy production demands.

Metallurgical & Hardness Profile

• • Raw Material: Certified high-grade 42CrMo / 4140 alloy tool steel with 100% spectrometric batch verification.
  • Heat Treatment Process: Full-body vacuum thermal treatment combined with localized high-frequency induction hardening on high-wear load surfaces.
  • Surface Hardness: HRC 55–60 in the working zone for maximum wear resistance, paired with a tough core engineered to absorb heavy impact without cracking.
  • Surface Roughness: Precision-ground contact faces with Ra < 0.8 µm finish to prevent galling and sheet marking on polished stainless steel and aluminum alloys.

Standard 4-Way Die Specification Matrix

V-Opening Selection & Sizing Rules for 4-Way Press Brake Dies

We apply exact engineering formulas based on material thickness (t) and alloy type to optimize every bend setup.

Air Bending Calculation Formulas

• • Standard Mild Steel (V = 8 x t): The standard rule for general sheet metal fabrication. Setting the V-opening to 8 times the sheet thickness yields consistent bend radii with balanced tonnage demand.
  • Tight Radii & Thin Gauge (V = 6 x t): Designed for thin-gauge forming and high-precision stainless steel processing where tighter inside bend radii are required.
  • High-Tonnage Plate (>6 mm) (V = 10–12 x t): Applied to heavy plate bending to reduce required tonnage, minimize wear on the 4-way press brake die, and prevent structural cracking.

V-Groove Angle & Radius Optimization

• • 88° and 90° V-Groove Angles: Engineered to account for material springback in carbon steel and high-tensile stainless steel alloys, ensuring accurate final 90° bends after release.
  • Engineered Shoulder Radii: Precision-ground shoulder radii lower friction during sheet entry, reduce overall bending tonnage requirements, and prevent surface scoring on delicate or finished sheets.

Machine & Clamping System Compatibility

Tang & Base Mounting Styles

• • Universal Square Block Profile: Fits directly into standard riser blocks and universal die holders without special modification.
  • Precision Alignment Tangs: Machined center tangs lock directly into bed slots, eliminating side-to-side play and manual alignment routines.
  • Repeatable Indexing: Keeps your tool centerline locked in place even after repeated manual or mechanical flips.

Press Brake Machine Integration

Our multi-V press brake dies support all major global press brake systems and clamping standards.

By utilizing optional adapter plates and integrated centering pin systems, every 90° die rotation preserves your backgauge reference points—eliminating recalibration delays between setup changes.

Operational Benefits: 4-Way Dies vs. Single-V Tooling

Setup Time & Tool Changeover Efficiency

• • Instant 90° Die Rotation: Operators achieve immediate V-opening changes by rotating the block 90° manually or mechanically—without removing the press brake die block from the press brake bed.
  • Zero Realignment Delays: Because the block stays seated on the bed, you eliminate time-consuming re-calibration and center-line adjustment routines across all four V-groove dimensions.

Cost & Storage Footprint Reduction

• • Up to 40% Lower Tooling Expenditure: Consolidating four individual bottom V-dies into a single rotating V-block tooling profile cuts capital investment significantly compared to purchasing separate standard bottom dies. Pairing this setup with insights from our press brake tooling material guide ensures maximum wear life and long-term return on investment.
  • Optimized Floor Space & Safety: Replacing four separate dies with one multi-V block frees up vital storage rack space and eliminates the need for overhead cranes or hoists during routine setups, drastically reducing operator injury risks.

Custom OEM/ODM 4-Way Die Manufacturing

Custom V-Groove & Asymmetric Geometry Engineering

We manufacture tailored custom press brake tooling designed to meet specialized sheet metal bending requirements. When standard multi-V blocks do not match your job specifications, we engineer custom 4-way press brake die solutions for non-standard bend angles, heavy-plate forming, and delicate surface finishes.

• • Specialized V-Grooves: Custom CNC machining for non-standard V-widths, acute angles (30°, 45°, 60°), and asymmetric V-profiles.
  • Optimized Shoulder Radii: Engineered shoulder contours to lower required bending tonnage, eliminate galling, and protect stainless steel and aluminum finishes.
  • Custom Lengths & Integrated Aids: Tailored block lengths up to 4150 mm equipped with ergonomic rotation handles for fast, safe die flipping.

CAMT 5-Step Rapid Development Workflow

Our end-to-end custom tooling development process moves your specialized 4-way press brake die from CAD concept to production with total dimensional accuracy.

Quality Assurance & Production Traceability

We build every 4-way press brake die to withstand heavy shop-floor demands without compromising bending accuracy. To guarantee long-term performance, our manufacturing facility operates under a strict quality control process that verifies material integrity and geometric precision at every production stage.

Precision Inspection Protocol

• • Spectrometric Material Verification: We analyze raw alloy composition using optical emission spectroscopy prior to machining to confirm true 42CrMo steel grade compliance.
  • CMM Laser Measurement: Coordinate measuring machines inspect concentricity, overall straightness, and V-groove angle accuracy across the entire block length.
  • Surface Roughness Testing: Optical profilometers measure ground contact faces to guarantee an Ra < 0.8 µm finish, preventing sheet marking on stainless steel and aluminum.

Export-Grade Protection & Delivery

• • Corrosion Protection: Full-coverage anti-rust oil treatment sealed inside heavy-gauge protective film.
  • Reinforced Crating: Heavy-duty export wooden crates designed to prevent shift, moisture ingress, and transit damage.

Compatible Accessories & Die Holders

Universal 4-Way Die Holders & Riser Blocks

• • Heavy-Duty Die Holders: Machined with integrated set screws and precision alignment keys to secure your 4-way press brake die without centerline deviation under load.
  • Riser Blocks & Height Adapters: Engineered for precise machine shut-height adjustments and direct compatibility with hydraulic clamping systems, including specialized configurations for Bystronic tooling and LVD tooling environments.

Rotation Handles & Manual Lifting Aids

Manipulating large, solid steel blocks requires safe, ergonomic handling solutions to maintain fast changeover times.

• • Ergonomic Rotation Handles: Heavy-duty handles attach directly to the ends of the die block, allowing operators to achieve smooth, controlled 90° manual turns without damaging the die bed.
  • Lifting Aids & Safety Locks: Designed to streamline die indexing, reduce hoist dependency on shorter setups, and protect operators during rapid V-groove transitions.

4-Way Press Brake Die FAQs

Concentricity During Rotation

• • Question: How do our CAMT 4-way dies maintain concentricity when rotated?
  • Answer: We execute standardized four-sided precision grinding and concentricity machining on every 4-way press brake die. This guarantees that the center line of every V-groove aligns precisely with your machine's bending axis whenever you flip the block 90°.

Tonnage Limits & Load Ratings

• • Question: What is the maximum tonnage capacity per meter?
  • Answer: Tonnage capacity depends on the block profile and V-opening size. Our standard 42CrMo heat-treated blocks handle 100–300 tons/meter. Review our engineering load charts when you choose press brake tooling for high-tonnage forming applications.

Custom V-Groove Modifications

• • Question: Can we manufacture custom V-groove combinations on a single block?
  • Answer: Yes. We provide full custom engineering to combine non-standard V-widths, acute angles (30°, 45°, 60°), or offset geometries into a single block based on your CAD files.
