Question 1

What material is used for your press brake punches and dies?

Accepted Answer

We primarily use high-grade 42CrMo (Chromium-Molybdenum Steel) or 42CrMo4 for our heavy-duty and CNC precision tooling.

Question 2

What is the hardness of the tooling, and what heat treatment is applied?

Accepted Answer

Our tools undergo rigorous overall quenching and tempering, followed by CNC induction hardening on the working edges. The final hardness reaches 45-50 HRC (or 48-52 HRC depending on customization). This ensures the core remains shock-absorbent while the bending edges are highly resistant to wear and deformation.

Question 3

Are your punches and dies compatible with my existing press brake machine?

Accepted Answer

Yes. We manufacture tools according to global industry standards, including European Standard (Amada / Promecam style), American Style. Simply provide us with your current clamping system photos or machine model, and we will ensure a 100% perfect fit.

Question 4

Do you offer sectioned (segmented) tooling sets?

Accepted Answer

Absoluteley. We provide both full-length tools (e.g., 835mm, 415mm) and standard sectioned sets (which include smaller segments like 10, 15, 20, 40,

Question 5

Can you customize punches and dies based on our specific product drawings?

Accepted Answer

Yes, we excel at OEM/ODM customization. If you have a complex bending profile, just send us your sheet metal part drawings

Question 6

How do I choose the correct V-opening width for the lower die?

Accepted Answer

As a general rule of thumb for mild steel:
For sheet thickness under 3mm: V = 6 to 8 *t (thickness).
For sheet thickness 3mm to 8mm: V = 8  to 10 *t.
For stainless steel or harder materials, a wider V-opening is recommended to reduce bending force and prevent cracking. Feel free to consult our team for a precise calculation!

Question 7

How can we avoid bending marks or scratches on delicate materials like stainless steel or aluminum?

Accepted Answer

To achieve mark-free bending, we can provide lower dies with larger shoulder radii, urethane/nylon inserts, or you can use our specialized anti-scratch bending cloth (protective film) placed over the V-die during operation.

Question 8

What is the maximum tonnage limit for these bending tools?

Accepted Answer

The load capacity depends heavily on the specific shape and height of the punch or die. All our high-precision tools have their maximum tonnage limit ($T/m$) stamped directly on the tool body for your safety. Never exceed the rated tonnage to avoid tool breakage.

Question 9

How should we maintain the tools to maximize their lifespan?

Accepted Answer

Always clean the sheet metal surface to remove rust or mill scale before bending. Clean the tools after use and apply a thin layer of anti-rust oil. Store them properly in an organized rack to avoid metal-to-metal collision on the sharp cutting edges.

Question 10

Do you provide a complete turnkey solution if we need to upgrade both our press brake machine and tooling?

Accepted Answer

Yes, we are a professional source manufacturer of both industrial press brake machines and high-precision tooling. If you are looking to scale up production, we can offer custom Machine + Tooling package deals with exclusive discounts. Buying both from us ensures 100% system integration, unified calibration, and one-stop after-sales support. Contact our sales engineers to discuss your project!

Question 11

What tolerances do you guarantee for your CNC precision tooling?

Accepted Answer

For our high-precision CNC series, we maintain strict manufacturing tolerances: height and parallelism are controlled within 0.01mm, and the center alignment tolerance is within 0.02mm. This exceptional precision ensures that when you combine multiple segments on your ram, there are no visible joints or uneven bending angles on your workpieces.

Question 12

Can your tools handle air bending, bottoming, and coining?

Accepted Answer

Yes. Our standard tools are optimized for air bending, which is the most versatile method for CNC press brakes. However, because we use premium 42CrMo steel with deep induction hardening (45-50 HRC), our heavy-duty punches and dies are fully capable of handling bottoming and coining operations that require significantly higher tonnages.

Question 13

How do you choose between a Straight Punch, an Acute Punch, and a Gooseneck Punch?

Accepted Answer

It depends entirely on your part geometry:

Straight/Standard Punches: Best for simple 90-degree bends and open profiles.

Acute Punches (30/45/60): Ideal for spring-back compensation and creating tight, acute angles.

Gooseneck Punches: Specifically designed with a deep inlay or cutout to clear previous bends when forming deep channels, hats, or closed boxes.

If you are unsure, send us your 3D part file, and we will simulate the bending sequence to select the right punch for you.

Question 14

Do you offer special surface treatments like Nitriding

Accepted Answer

Yes, we offer optional surface treatments such as Nitriding (Black Oxide Finish) or Phosphating. These chemical processes increase the surface hardness up to 60-65 HRC, significantly reduce friction between the sheet metal and the die shoulder, eliminate galling (especially when bending aluminum or galvanized steel), and provide superior rust prevention.

Question 15

How do you pack the tools to ensure they arrive without damage or rust during international shipping?

Accepted Answer

We take export packaging very seriously. Every tool is thoroughly cleaned, coated with heavy-duty marine-grade anti-rust oil, and wrapped in vacuum sealed plastic film. They are then securely packed into custom, heavy-duty fumigated wooden boxes with internal foam padding to prevent any metal-to-metal impact or moisture damage during sea or air transit.
