The introduction of Punch and Die Components
Punch and Die components are essential tools in the manufacturing process, particularly in sheet metal fabrication. They are used in a punch press to cut holes and shapes into metal by shearing. The punch is a hard metal rod with a shaped tip that matches the desired cutout shape. The die, on the other hand, is a flat metal piece with a hole that corresponds to the punch’s tip. When the punch press forces the punch into the die, the material lying between them is cut or shaped accordingly.

Showcase of Our Common Products
Punch and die components come in various shapes and sizes, tailored to create a wide range of hole sizes and shapes.
Material Selection
These materials and grades are chosen based on their specific properties like hardness, wear resistance, and toughness, which directly impact the tool’s performance and the precision of the stamped parts.
| Material | Characteristics | Hardness Range | Manufacturing Precision | |
|---|---|---|---|---|
 | High-Speed Steel（M2,1.3343,EM2,SKH51) | Excellent wear resistance, high toughness, suitable for high-speed operations | 58-64 HRC | ±0.005mm - ±0.01mm |
 | Tungsten Carbide ( brands from EVERLOY,FYJILLOY,CERATIZIT,KENNA) | Extremely high hardness, superior wear resistance, but more brittle than HSS | 85-94 HRA | ±0.002mm - ±0.005mm |
 | Tool Steel (A2, D2, DC53) | Good balance of wear resistance and toughness, widely used in stamping tools | A2: 58-62 HRC, D2: 55-62 HRC, DC5356-59HRC | ±0.005mm - ±0.01mm |
 | Powdered Metals (ASP23, ASP30) | High uniformity, excellent material properties, suitable for complex shapes | ASP23: 60-65 HRC, ASP30: 63-67 HRC | ±0.005mm - ±0.01mm |
 | High Carbon High Chromium Steel (D3, D6) | High wear resistance and hardness, suitable for detailed work | D3: 62-64 HRC, D6: 58-62 HRC | ±0.005mm - ±0.01mm |
Various of Coating
In stamping and plastic mold industries, various coatings are applied to enhance tool performance, extend service life, and optimize manufacturing processes.
| Coating Type | Color | Thickness (µm) | Applications | |
|---|---|---|---|---|
 | Titanium Nitride (TiN) | Gold | 1-4 | General-purpose coating, increases surface hardness, reduces wear, and improves tool life. |
 | Titanium Carbonitride (TiCN) | Violet-gray | 2-4 | Higher hardness than TiN, suitable for high-speed and high-temperature applications. |
 | Chromium Nitride (CrN) | Silver-gray | 1-5 | Excellent for corrosion resistance, good for forming and punching tools especially in HSS. |
 | Aluminum Titanium Nitride (AlTiN) | Black to dark gray | 1-4 | High thermal stability, ideal for high-speed machining, dry or semi-dry machining of steel. |
 | Diamond-like Carbon (DLC) | Black | 1-3 | Low friction, high hardness, suitable for non-ferrous metal stamping, and plastic molding tools. |

The Common Issues for Punch and Die Components
Sometimes,we will encounter some common issues with punch and die components in stamping operations as follows :
- Wear and Tear: Frequent use leads to gradual wear, reducing the sharpness and efficiency of punches and dies, affecting the quality of stamped parts.
- Chipping and Breakage: High-stress environments can cause parts of the punch or die to chip or break, especially with brittle materials like tungsten carbide.
- Galling: Material transfer from the workpiece to the punch or die surfaces, leading to unwanted buildup that can interfere with the stamping process.
- Corrosion: Exposure to certain materials or environmental conditions can cause corrosion, compromising the integrity and performance of the tooling.
- Misalignment: Improper alignment of the punch and die can lead to uneven wear, part defects, and an increased risk of tool damage.
- Springback: Material elastic recovery after the stamping process can lead to dimensional inaccuracies in the final product, posing challenges in maintaining tight tolerances.
