一, What thermal treatment does

resistant to wear: Heat treatment changes the surface structure of the mold, which less likely to wear out during processing.

Brass tension spring get rid of internal stress that builds up during processing to stop the mold from bending or cracking.

Increase fatigue resistance: By changing the grain size and improving the microstructure, the mold is less likely to stretching cycles.

Enhancing processing efficiency: Annealing Double ring tension spring can make the mold more flexible and durable, which makes it easier to do precision machining or troubleshooting later on.

二,surface hardening

Different brass alloys, like zinc brass, aluminum brass, and tin brass, react differently to heat treatment.

Aluminum brass, for instance Rubber tension spring , is good for age treatment to make it harder, while regular zinc brass is mostly annealed and tempered.

Based on the setting in which the mold is used

need to be made and processed continuously for a long time, thus they need methods that are very resistant to wear, like surface hardening or aging treatment.

Basic annealing or tempering techniques can be used to save money on small batches or applications with low strength.

Composite heat treatment, which includes annealing, aging, and surface hardening, can be used to treat high life molds.

Molds with normal lifespans can pick one heat treatment method.

Finding the right balance between expense and difficulty of processing

Advanced procedures like surface coating or nitriding are expensive and can be used to make molds for Double ring tension spring or very precise custom molds.

Basic annealing and tempering techniques might help save money on small batch or custom molds.

三,Precautions

Set the time and temperature of the heating to stop mold from warping or getting too soft.

Make sure the heat treatment method is the same throughout and doesn''t cause stress to build up in one spot.

Brass tension spring on custom molds, like checking their hardness, wear resistance, and fatigue life.

You can change the heat treatment method to fit the production batch and the environment in which it will be used
