China Changzhou Tiangong Forging Co., Ltd. company news

Free forging, also known as open-die forging, is a metalworking process that shapes metal without the use of a die to confine the workpiece. Instead, the metal is deformed between two simple, flat or shaped dies, allowing it to move and expand in all directions. This method is one of the oldest and ... Read More

As the world accelerates its shift toward sustainable energy, wind power continues to gain momentum as a clean and efficient energy source. The increasing size and performance demands of wind turbines have placed higher expectations on the mechanical properties of core components. Forged steel parts ... Read More

What Is Free Forging? Free forging is a forging process in which a metal workpiece is shaped by compressive forces between flat or simply shaped dies. Unlike closed-die forging, where the material is fully enclosed by the die, free forging allows more open shaping and manipulation of the metal. This ... Read More

As the global demand for high-strength, custom-shaped metal components grows, free forging—also known as open-die forging—continues to be a cornerstone in the metal forming industry. With its flexibility, cost-effectiveness, and ability to produce high-quality parts, free forging plays a vital role ... Read More

Enhancing Reliability, Performance, and Cost Efficiency in Renewable Energy Infrastructure As the global wind energy sector expands—with capacity expected to reach 1,400 GW by 2030 (Global Wind Energy Council, GWEC)—the demand for high-integrity turbine components has never been greater. Free ... Read More

1. Open Die Forging Definition: Also called free forging, where the workpiece is compressed between flat or simple-shaped dies that do not fully enclose the material. Metal flows freely outward during deformation. Process: The workpiece is hammered/pressed repeatedly, with operators repositioning it ... Read More

The terms "free forging" and "open die forging" are often used interchangeably in the metalworking industry, but there are subtle differences in their technical definitions and applications. Here’s a clear breakdown: 1. Free Forging Definition: A broad term referring to forging processes where the ... Read More
