Forging

We offer a comprehensive range of forged shapes and products, manufactured using our various range open die hammers machine. The benefits of our forged products include increased material strength, reduced machining and material waste though near net shape manufacture, and lower material costs.

Forging describes a procedure of production of forged parts in order to form the metal with making use of comprehensive forces. Basically, it is identified on the basis of temperature as hot, warm or cold. The weight of these forged parts varies from one kg to 580 metric lots.

Renyicastings is just one of the leading steel forging producers. We have actually served all major markets such as Building, Railways, Mechanical sectors, Oil refineries, Mining industry, and so on. We have a wealth of experience functioning as a forging parts producer- Three years to be exact. We have the deepest and the width of experience in the market.We aim to accomplish our vision by preserving a rigorous quality of the elements we provide. We additionally guarantee consumer contentment with solutions that go beyond assumptions as well as offers global basic iron, spreading shop, makers, iron spreading’s, copper tubes, hot & chilly forging for sectors.

We control and witness hot forging working processes through manufacturing procedures and on-site metallographic observation to ensure that the final product meets the customer’s specific requirements.

Advantages of Forgings

Forgings offer a number of outstanding advantages over parts produced by other manufacturing processes. These advantages result from the inherent properties of copper and copper alloys plus additional improvements in mechanical and physical properties imparted by the forging process.

High Strength

In making a forging, the metal is worked twice under tremendous pressures-first during rod extrusion and then during forging. The double working under pressure compacts the metal and produces a very dense and refined grain or fiber structure.

The tensile strength of the parts is thereby increased, and resistance to impact and abrasion is enhanced.

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 piece cost compared to other forming processes.

Close Tolerances

A forging produced in a steel die with close tolerances offers several advantages. 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.

Low Overall Cost

Mass production of forged parts lends itself to maximum savings. However, smaller quantities of copper alloy forgings can also prove economical when specific design problems must be solved. These problems include leak integrity, close tolerances, high strength with low weight, and non-symmetrical shape.
