What is Precision Die Stamping?

July 27, 2024

Die stamping is a specialized process used in cold stamping to shape materials (metal or non-metal) into parts (or semi-finished products) using unique equipment known as cold stamping dies (commonly referred to as cold stamping molds).

Precision die stamping is a highly accurate manufacturing process used to create detailed and complex metal parts and components. This technique involves using specialized molds and stamping machines to shape and cut metal sheets with exceptional precision.

Understanding the Die Stamping Process

Die stamping processes are categorized by the temperature at which they are performed: hot stamping and cold stamping. Hot stamping is suitable for materials with high deformation resistance and poor plasticity, while cold stamping is performed at room temperature and is commonly used for thin sheets.

Requirements for Stamping Materials:

Precise and Uniform Thickness: The thickness of the stamping material must be accurate and consistent.

Smooth Surface: The surface should be clean, free of stains, scars, scratches, and surface cracks to avoid producing defective products.

Uniform Yield Strength: The material should have uniform yield strength without noticeable directional properties to reduce defects and waste.

High Uniform Elongation: The material should have high uniform elongation to prevent uneven deformation.

Low Yield-to-Tensile Strength Ratio: This helps improve the accuracy of bent components.

Low Work Hardening: This helps prevent deformation in later stages.

The precision and structure of the die directly affect the formation and accuracy of the stamped parts. The cost and lifespan of the die are crucial factors affecting the cost and quality of the stamped parts.

Materials for Precision Die Stamping:

Materials used for manufacturing stamping dies include steel, carbide, steel-bonded carbide, zinc-based alloys, low-melting-point alloys, aluminum bronze, and high polymer materials. The majority of stamping dies are made from steel. Common materials for die working components include carbon tool steel, low alloy tool steel, high carbon high chromium or medium chromium tool steel, medium carbon alloy steel, high-speed steel, base steel, as well as carbide and steel-bonded carbide.
