Fin die supplier of Heat exchangers in China

Heat exchanger fin die

The Heat exchanger fin die, also referred to as fin progressive dies, are dies that are divided into a number of evenly spaced stations depending on the workpiece being processed. At each station, one or more fundamental stamping operations are set up to finish processing a particular portion of the stamping workpiece.

The material to be processed must be cut into strips of a specific width beforehand, and a specific feeding technique must be used to feed the material one step at a time.
A finished stamping workpiece is obtained after punching each hole individually.

Blanking, bending, drawing, shaping, and other processes can be carried out constantly in the ten pairs of fin progressive dies.
Using a set of Continuous fin mold and fin progressive dies, stamping may be done regardless of how intricate the shape of the stamped object is or how many stamping operations are involved.

application field

Fin die is a continuous stamping die that punches raw materials such as aluminum foil, copper foil, and stainless steel foil into precision molds of various shapes,

With the development of technology, people’s demands for energy conservation and environmental protection are constantly increasing,

Fin die is transitioning towards high precision and diversification, producing a range of products such as stretched fins, curved fins, elliptical tube fins, and flat tube fins.

This type of fin can be applied to industrial condensers, household convective heat exchangers, automotive evaporators, and other fields
