Core Technologies and Features of Cold Extrusion Hydraulic Presses for Automotive Parts

A cold extrusion hydraulic press for automotive parts is a hydraulic device specifically designed to apply extremely high pressure to metal billets at room temperature, causing plastic deformation within a mold cavity to obtain precision forgings of the desired shape, size, and performance. Below is a brief description of the core technologies and features of this machine by Jianlong Hydraulic Technology for your reference!

Compared to ordinary hydraulic presses or hot forging equipment, cold extrusion hydraulic presses have the following outstanding technical features:

1. Extremely High Tonnage Pressure: 

Cold extrusion requires high deformation resistance, typically hundreds to thousands of tons of pressure. Common tonnages include 630T, 800T, 1600T, 2500T, and even higher.

2. High Rigidity and Precision:

2.1 The machine body is made of high-quality cast steel or welded steel plates, optimized through finite element analysis to ensure minimal deformation under extreme loads.

2.2 High guiding precision ensures accurate alignment of the upper and lower dies, resulting in stable and consistent dimensions of the produced parts.

3. Precise Control System:

3.1 Employs a PLC (Programmable Logic Controller) and a touchscreen human-machine interface for precise control of pressure, speed, stroke, and holding time.

3.2 Features data storage, fault diagnosis, and networking capabilities to meet the demands of intelligent production.

4. High Production Efficiency and Automation:

 Modern cold extrusion hydraulic presses typically integrate robotic arms or robots for automated feeding and unloading, forming automated production lines and significantly improving production efficiency.

5. Process Advantages (Compared to Hot Forging and Machining):

5.1 High Material Utilization: Approaching net-shape forming, reaching over 85%, far exceeding machining, saving materials.

5.2 Improved Part Mechanical Properties: The work-hardening effect refines the grain size of parts, significantly improving strength, hardness, and fatigue life.

5.3 Good Surface Quality: High dimensional accuracy and excellent surface finish, generally allowing for direct assembly or requiring only minimal finishing.

5.4 Energy Saving and Environmentally Friendly: No heating required, saving energy and providing a better working environment.

Cold extrusion hydraulic presses, through high-pressure, precision plastic deformation technology, provide lightweight, high-strength, high-precision, and low-cost core components for the automotive industry, playing a vital role in driving technological progress and transformation in the automotive sector.
