Advantages of Our Company in Terminal Stamping Mold Manufacturing

Terminals are essential core components in electronic connectors, and their production demands exceptional precision and quality.

Our company excels in meeting these requirements by our advanced process capabilities and expertise:

1. High Precision (Micron-Level Tolerance)

To ensure reliable matching with other components, critical features such as bend angles and pin pitches must be held within tolerances of less than 0.1 mm. This requires molds with superior precision. Our machining equipment’s tolerances reach ±2 µm, significantly exceeding the standards of stamping dies.

2. Super Surface Quality

To ensure optimal conductivity and flawless plating, terminal surfaces must be free of burrs and scratches. Minor burs can lead to short circuits. Our molds feature sharp cutting edges and precisely controlled clearances, enabling clean, burr-free stamping.

3. Expertise in Complex Geometries

Modern terminals often require multiple forming operations—such as blanking, bending, cutting, and deep drawing—integrated into a single progressive die. Our mold designers specialize in creating complex, multi-processes into one progressive die.

4. High-Speed Production & Extended Tool Life

Because of the high-volume demand for terminals, the mold often needs 1,000+ strokes per minute. To support continuous and high-speed operation, our molds are made from high-rigidity, high-toughness materials, such as SKD11, DC53, and tungsten carbide alloys, ensuring durability and long service life.

How to Ensure the Terminal Progressive Dies Quality?

1. High Precision Die Set and Guiding System

We employ high precision-guided systems—including ball-bearing guide posts and bushings, as well as dual guiding mechanisms. High precision ensures the upper and lower dies alignment during high-speed stamping.

2. Plate Assembly

Manufactured with the highest tolerances, our plate assemblies prevent movement or deformation during die clamping, ensuring consistent stamping in production.

3. High Quality Forming System

These are the "actuators" that carry out all the operations; the material grade always determines the mold life. All punches and dies are fabricated from ultra-hard, wear-resistant materials—such as high-speed steel SKH-51, SKD11, DC53, and tungsten carbide alloys (YC20C, YG20)—ensuring longevity and consistent performance.

4. Feeding and Positioning System

Our automatic feeding system feeds the material into the die step-by-step. Additionally, guide pins engage with pre-punched positioning holes before each station, correcting any feeding misalignment.

5. Safety and Monitoring System

Misalignment or feeding errors are instantly monitored; the system will automatically shut down to prevent mold damage and reduce downtime.
