What Is Brass Hot Forging? 

According to the forging temperature, forging can be classified into hot forging, cold forging and warm forging. Most mental components intended to be forged are performed under hot forging.

Brass hot forging can be defined as “ a shaping process in which a brass bar, is worked to a predetermined shape by one or more processes such as hammering, upsetting, pressing and so forth where the bar is heated up to about 75% of its melting temperature”. The process begins with a cast ingot, which is heated to its plastic deformation temperature, then forged between dies to the desired shapes and size.

 The Advantages & Benefits of Brass Hot Forging

The brass hot forgings are quality parts, comparing favorably in material integrity, dimensional tolerance and surface finishing with products made using other major metalworking processes. As a result of deformation, hot brass forging grants superior density and freedom from flaws. Forming under heat and pressure in precise closed dies produces dimensional accuracy, always repeatable part to part and lot to lot. 

The specific advantages of brass hot forging parts are as follows:

1. Higher Strength

As the forging temperature of the brass bar is prior to the melting temperature, the flow stress and energy required to form the material are decreased and the strain rate or production rate can also be increased. Therefore, hot forging results in metal that is stronger than cast or machined metal parts.

2. Lower Overall Cost

Mass production of brass forged parts lends itself to maximum savings. However, smaller quantities of copper alloy forgings can also prove economical when specific design problems must be overcome. These problems include leak integrity, close tolerances, high strength with low weight, and non-symmetrical shape. Besides, hot forging don’t have to reach the molten temperatures.

3. Leak Resistance

The dense non-porous forged metal permits the designer to specify thinner sections without the risk of leaks due to flaws and voids. Often the thinner forged parts result in lighter weight and lower part cost compared to other forming processes.

4. Close Tolerances

Overall part dimensions are held closer than in sand casting. Dimensions show minimum variation from part to part and permit automatic chucking and handling in subsequent operations. The precise designs on the die surface can produce sharp impressions on the forging surface, which is not economical with other forming processes.

 What’ s the Differences Between Hot Forging and Cold Forging?

The cold forging manufacturing process is performed at room temperature. While the hot forging manufacturing process is performed at extreme high temperature (up to 1150°C for steel, 360 to 520°C for al-alloys, 700 to 800°C for cu-alloys).

The cold forging manufacturing process increases the strength of a metal through strain hardening at a room temperature. On the contrary the hot forging manufacturing process keeps materials from strain hardening at high temperature, which results in optimum yield strength, low hardness and high ductility.

FAQ

1.  can design the drawings for me?

Sorry, we can't provide the design service. Please send your 2D,3D,PDF or CAD drawings to us, we will provide the manufacturing design review after receiving your order.

2. How can I know  that my design will be secret?

We will sign and comply with any non-disclosure or confidentiality agreement.  And we had the strict policy in our factory, anyone can't take the photos for customer's products without permit.

3. How does compare to the price of other suppliers?

Though the compare is difficult directly, but ZH compare with China supplier, we don't compare the price, but provide the higher-level quality, rapid response, on time delivery and standard service.

 4. What tolerances can ZH achieve?

There is not a set of tolerances fit all of the process and materials. In different situations, the final to tolerances of parts will be depend on the many factor, including but not limited to part dimensions, design geometry, quantity, type and size materials

surface treatment and manufacturing process. ZH have a whole set of part inspection standards, all of the fabrication and technical specifications need clear define in the part inspection standards.

 5. How does  ensure the quality of my parts?

Once your order is confirmed, we will execute the whole fabricate design (DFM) review, so that our engineers think that maybe affect any quality problems of your parts. And we will use a set of test equipment to check and confirm the all materials.

Also, we promise 100 percent inspection before shipping.

 We are able to real-time sharing the inspection data with you, so we also can work together to solve any quality problems that you may encounter during the production process.

6. What type of surface treatment does provide?

We provide all kinds of surface treatment service, like zinc plating, anodizing, chrome plating, nickel plating, blacking oxide coating, electrophoretic paint, powder coating etc.

7. What if I am not completely satisfied with the parts I received?

According to the customer's drawings, materials and technics, we produce the parts with strict inspection to meet customers’ requests, so our company does not take any responsibility. But if the problem is caused by our processing negligence, we will 100%  take responsibility and negotiate settlement program with you.

8. How do I pay f ?

ZH accept the payment method as following:

1.T/T wire transfer

2. also can accept the western union
