Precision TiN Stamping Punch Pins

Tungsten Carbide Punch Dies for High-Accuracy Metal Forming

Product Overview

Precision TiN Stamping Punch Pins & Tungsten Carbide Punch Dies are high-performance tooling components used in precision stamping and cold heading applications.

These punch pins are primarily used for:

• Screw head forming

• Recess pattern shaping

• Cold forging operations

• High-speed stamping production

Supported recess types include:

• Phillips

• Pozi

• Hexagon

• Square

• Six-lobe (Torx type)

• Custom profiles

Manufactured from premium tungsten carbide or high-speed steel (HSS), these punch dies are engineered for long service life, consistent geometry, and high dimensional stability under repeated impact loading.

All products are OEM / Built-to-Print according to customer drawings.

Material & Coating Advantages

Tungsten Carbide Punch Dies

Tungsten carbide provides:

• Extremely high wear resistance

• Excellent compressive strength

• Stable hardness under high-speed stamping

• Reduced tool replacement frequency

Hardness range: 60–80 HRC (depending on material grade)

Ideal for high-volume production environments.

TiN Coated Punch Pins

TiN (Titanium Nitride) coating offers:

• Reduced surface friction

• Increased surface hardness

• Improved anti-galling performance

• Extended tool life

Optional coatings available:

• TiN

• TiCN

• TiAlN

• Nitriding

• Black oxide

Coating selection is based on stamping material and production speed.

Manufacturing Process & Machining Focus

Precision punch pins require strict process control to maintain tip geometry and durability.

1️⃣ Raw Material Preparation

• Certified carbide or HSS material selection

• Diameter drawing and blank cutting

• Material verification before machining

Material stability directly affects punch life and accuracy.

2️⃣ Heat Treatment (for HSS Punches)

• Controlled heating at 800–1300°C

• Oil quenching

• Low-temperature tempering

• Hardness verification

Carbide punches are supplied pre-hardened.

3️⃣ Precision Grinding & Forming

Critical machining focus includes:

• Tip angle accuracy

• Recess profile geometry

• Diameter tolerance

• Concentricity control

Grinding is performed using precision collet clamping systems to minimize runout.

4️⃣ Surface Finishing & Coating

• Fine polishing

• Surface cleaning

• TiN or advanced coating application

• Surface inspection

Surface finish quality directly impacts stamping clarity and tool life.

5️⃣ Inspection & Quality Control

Each punch die undergoes:

• Dimensional inspection

• Profile verification

• Hardness testing

• Surface finish check

Only qualified products proceed to packaging and storage.
