During the critical period of transformation and upgrading of the manufacturing industry, Jin Qiang Machinery officially put into production two cold heading equipment imported from Germany, with a total investment of 3 million yuan. This upgrade not only greatly increased the production capacity of precision bolts, but also marked the company’s breakthrough progress in the field of metal forming technology.
Cold Heading VS. Hot Forging: Key Differences
1. Process Temperature
- Cold Heading:Shapes metal at room temperature using extreme pressure.
- Hot Forging: Requires heating materials above 1,000℃ for plasticity.
2. Technical Advantages
- Cold Heading:
- Superior dimensional accuracy (±0.05mm tolerance)
- Enhanced strength through “work hardening”
- 30-50% energy savings (no heating required)
- Minimal material waste and oxidation
- Hot Forging:
- Better for large/complex shapes (e.g., engine components)
- Lower forming pressure requirements
3. Application Focus
- Cold Heading: Ideal for mass-producing high-strength, precision fasteners (T bolt, BPW, 37#,41#).
- Hot Forging: Preferred for oversized parts or specialized geometries.
Strategic Benefits of Cold Heading
1. Enhanced Performance
Work hardening effect increases tensile strength by 15-30%
2. Precision Control
Dimensional tolerance within ±0.05mm
3. Sustainable Production
Reduces energy use by 30-50% VS. hot forging
The technical director of our company said: “The introduction of cold heading technology is not only an equipment upgrade, but also an innovation in the production model. In the next three years, we will take cold heading technology as the core, and build an automated shot blasting line and an intelligent storage system to form a “dark factory” model from raw materials to finished products. At the same time, in view of the irreplaceable nature of hot stamping technology in complex structural parts, we will cooperate with universities to develop “cold and hot composite forming” technology to break through the limitations of a single process.This technical upgrade will increase the annual production capacity of our company’s bolt products to 80 million pieces and reduce unit energy consumption by 22%
Executive Statement
“This investment anchors our strategy for precision-engineered solutions,” stated ShuiSheng Fu, Manager. “The technology enables production of high-strength bolts with 20% lower carbon emissions.”
