The difference between hot forging and cold forging in forging forming hydraulic press?
Inforging forming hydraulic press中，根据锻造工艺不同分为热锻成形液压机和冷锻压成形液压机，为方便大家采购到合适的机型，下面山东众友重工液压机厂家就热锻压和冷锻压区别做简要介绍。
Hot forging:
Processing at a higher recrystallization temperature than the billet metal is called hot forging. Increasing the temperature in hot forging can improve the plasticity of the metal, which is beneficial to improve the internal quality of the workpiece and make it difficult to crack.
高温度还能减小金属的变形抗力，降低所需锻压机械的吨位。但热锻工序多，工件精度差，表面不光洁，锻件容易产生氧化、脱碳和烧损。在精密锻造中热锻工艺常常与冷锻压、温锻压结合运用，形成冷温热复合精密成形工艺。

Cold forging:
Forging of parts at room temperature is called cold forging. The cold forging process is a precision plastic forming technology and a (near) net forming process. Cold forging has unparalleled advantages in machining, such as good mechanical properties of products, high productivity and high material utilization, especially suitable for mass production, and can be used as a manufacturing method of final products, in transportation, aerospace and machine tool industries and other industries have a wide range of applications. At present, the rapid development of automobile industry, motorcycle industry and machine tool industry has provided the driving force for the development of cold forging technology.
Shandong Zhongyou Heavy Industry Machine Tool Co., Ltd. customizes various hot forging and cold forging forming hydraulic press equipment on demand. This series of products have fast working speed and are equipped with automatic mold spraying and lubricating systems. The hydraulic system adopts electro-hydraulic proportional servo system with high pressure accuracy and high positioning accuracy to meet the needs of different processes for hydraulic presses. Die forgings can achieve less cutting or no cutting, high efficiency and low cost of producing workpieces, and are being used more and more in machining.
