Progressive Stamping Dies for Metal Terminals

1. Introduction

Progressive stamping dies for metal terminals are specialized tools used in high-speed, high-precision metal stamping. These dies are designed for the continuous production of electrical and electronic connectors, automotive terminals, and precision metal contacts.

With the ability to perform multiple stamping operations in a single press cycle, these molds ensure efficient, cost-effective, and high-quality manufacturing.

2. Characteristics of Progressive Stamping Dies for Metal Terminals

Key Features:
- High-Speed ProductionCapable of operating at 200–1,500 strokes per minute, ensuring mass production efficiency.
- Multi-Stage Forming in One DiePerforms punching, bending, forming, cutting, and coining in a single process.
- High Precision & ConsistencyMaintains tight tolerances (±0.01mm to ±0.05mm) for intricate terminal designs.
- Durable & Long-LastingMade from high-hardness tool steel (SKD11, DC53, D2, Cr12MoV) with heat treatment (HRC 58-62).
- Material OptimizationReduces material waste through optimized strip layout and precise cutting techniques.
- Automated & Continuous OperationWorks with automatic feeding systems and coil strips, improving production speed and reducing labor costs.
