Product Q&A

Q:Are you a manufacturer or a trade company?

We are a professional manufacturer of fastener mould with over 10 years of experience in this industry.

Q:What is a cold forging die, and how does it function?

A cold forging die is a specialized tool used to shape metal at room temperature through high-pressure deformation by applying force to a metal blank without heating it.

Q:What materials are used for cold forging dies?

Typically made from high-grade tool steels like H13 or SKD61, or carbide, chosen for exceptional hardness, wear resistance, and toughness.

Q:What are the main advantages of using cold forging dies?

Advantages include high-strength components, cost-effective mass production, superior surface finish, and reduced energy consumption compared to hot forging.

Q:What advantages do you have?

We mainly have three capabilities: 1. Professional mould simulation development and design capability. 2. High-precision and high-stability mould manufacturing capability. 3. Optimization capability for continuous improvement of mould life.
