Detailed introduction of accuracy level
We provide various PVD coatings such as TiN, TiCN, CrN, AlTiN, etc., suitable for punch&pin, punch die, Mold Punch, Guide Post and other mold components. By enhancing hardness, reducing friction and improving wear resistance, we extend mold life and improve production efficiency
Coating Quick Navigation
TiN (universal wear-resistant+decorative gold)
TiCN (high hardness and wear resistance+low friction)
CrN (strong resistance to adhesion and demolding)
AlTiN/TiAlN (thermally stable high hardness)
Composite and high-end coatings (ZrN, DLC, AlCrN, etc.)
Functional description paragraph: For example, TiCN has a hardness of up to 3000 HV and a lifespan 2-4 times that of TiN; CrN coating can prevent sticking in high friction environments; AlTiN is suitable for hot forging tools due to its high temperature stability.
Advanced Coating Performance
| Coating Type | Technical Properties | Performance Advantages | Ideal Applications | Benchmark Data |
| TiN (Titanium Nitride) | – Hardness: HV 2300 – Thickness: 2-4μm – Friction Coefficient: 0.4-0.6 | – 200% lifespan increase vs. uncoated tools – Excellent adhesion (HF1 per VDI 3198) – Cost-effective for general use | – Blanking dies – Plastic injection molds – Cutting tools | ISO 20523:2017 Wear rate: 1.2×10⁻⁶ mm³/Nm |
| AlCrN (Aluminum Chromium Nitride) | – Hardness: HV 2800 – Max Temp: 800°C – Oxidation Resistance: >1000h@700°C | – 150% higher thermal stability vs. TiN – 3X better oxidation resistance – Maintains hardness at elevated temps | – High-speed stamping – Hot forging dies – Extrusion tools | DIN EN 1071-2 Thermal cycling: 5000+ cycles |

TiN (Titanium Nitride) Coating – The Cost-Effective Workhorse for General Tooling
Technical Breakdown & Applications:
TiN’s gold-colored coating provides a hardness of HV2300 (2X harder than tool steel) through PVD deposition. Its balanced 2-4μm thickness and moderate friction (μ=0.4-0.6) make it ideal for high-volume stamping of mild steels and plastics, where it extends die life by 200% versus uncoated tools. For example, in washer blanking dies, TiN maintains sharp edges for over 500,000 cycles. However, its oxidation resistance limits use to <600°C – avoid aluminum/magnesium hot forming. Best for budget-conscious production of automotive fasteners and consumer electronics molds.
AlCrN (Aluminum Chromium Nitride) Coating – The Thermal Warrior for Extreme Conditions
Technical Breakdown & Applications:
With HV2800 hardness and 800°C thermal stability, AlCrN’s nano-layered structure forms a protective Al₂O₃ layer at high temps. This coating shines in high-speed stamping of stainless steels (e.g., automotive exhaust parts), where it lasts 3X longer than TiN under thermal cycling. Real-world data from progressive dies show 1.2 million presses before recoating vs. 400K with TiN. The gray-violet coating requires polished substrates (Ra≤0.1μm) for optimal adhesion. Perfect for hot forging brass fittings or titanium medical component forming.
DLC (Diamond-Like Carbon) Coating – The Friction Slayer for Precision Applications
Technical Breakdown & Applications:
DLC’s amorphous carbon matrix delivers HV3000-4000 hardness and the industry’s lowest friction (μ<0.1). Its 50% surface roughness reduction (to Ra<0.05μm) prevents material adhesion in medical needle punching or connector pin stamping. In iPhone SIM tray molds, DLC achieves 2M+ cycles without galling. The black coating is deposited via PACVD at <200°C, making it safe for pre-hardened steels. Though costly (2.5X TiN), it’s unmatched for non-lubricated forming of copper/beryllium alloys.
