High Strength		In making a forging, the metal is worked twice under tremendous pressures. First during rod extrusion, drawing or rolling 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. Often, the thinner forged parts result in lighter weight and lower piece cost compared to other manufacturing processes.

Close Tolerances		hot forging part 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 allowing for automatic chucking and handling in subsequent operations. The precise designs on the die surface can produce sharp impressions on the forging surface.

Low Overall Cost		Mass production of hot forging part lends itself to maximum savings. However, smaller quantities of copper alloy forgings can also prove economical when specific design parameters must be met. These requirements include leak integrity, close tolerances, high strength with low weight, and non-symmetrical shape.

Cold woke is one article of Forging.An example of desirable work hardening is that which occurs in metalworking processes that intentionally induce plastic deformation to exact a shape change. These processes are known as cold working or cold forming processes. They are characterized by shaping the workpiece at a temperature below its recrystallization temperature, usually at the ambient temperature.[5] Cold forming techniques are usually classified into four major groups: squeezing, bending, drawing, and shearing. Applications include the heading of bolts and cap screws and the finishing of cold rolled steel. In cold forming, metal is formed at high speed and high pressure using tool steel or carbide dies. The cold working of the metal increasing the hardness, yield strength, and tensile strength.

HS Machinery Parts is a factory producing steel castings, iron castings, aluminum castings, brass castings, bronze castings, forgings, stampings, and machined parts with material carbon steel, alloy steel, stainless steel, aluminumalloy, copper alloy such as brass and bronze. Products more than 85% export toUSA, Europe, and other countries, and quality obtained very good reputation from our customers. Electric zinc, hot dip zinc plating, power coating, painting, phosphatization are the most common anti rust surface treatment, others you can specify.

In order to your best assurance of all castings will conforming and complying with your specifications, we focus on quality control process. We provide first piece inspections and final casting inspections to verify the quality of the entire production run. Allinvestment casting tools are inspected prior to each issuance to the injection floor. We also can supply chemical, physical, and non-destructive testing such as spectrographic analysis, radiography, fluorescent zyglo, and more. We will work with you to verify we can meet the best testing process for your application.

Welcome to send us your drawings and requirement, we'll offer you the best quality products but in competitive price.
