What are the advantages of four column hydraulic press?

The four-column hydraulic press offers significant advantages in a number of ways:

First, it excels in reducing the weight of parts. For automotive engine bracket and radiator support and other common parts, hydroforming parts compared to stamping parts, the weight can be reduced by 20% to 40%, for hollow stepped shaft parts, and even reduce the weight of up to 50%, thus significantly improving the efficiency of material use.

Secondly, hydroforming simplifies the production process and reduces the need for tooling. Typically, only one set of molds is required for a hydroformed part, while multiple sets are often needed for stamped parts. For example, engine bracket parts can be reduced from 6 parts to 1 by hydroforming, and radiator support parts are also reduced from 17 to 10, which significantly reduces tooling costs.

Further, it can reduce the subsequent machining and assembly welding work. Taking the radiator support as an example, after adopting hydroforming, the heat dissipation area increases by 43%, the number of welding joints is reduced from 174 to only 20, and the production process is also reduced from 13 to 6, which improves the production efficiency by up to 66%.

In terms of performance, hydroforming improves not only efficiency, but also the strength and stiffness of parts. For example, the radiator support in the vertical and horizontal direction of the stiffness increased by 39% and 50%, especially in the fatigue strength, outstanding performance.

Finally, the economic benefits cannot be ignored. Statistics show that the production cost of hydroforming parts compared to stamping parts by an average of 15% to 20%, and tooling costs can be reduced by 20% to 30%, which means a significant reduction in overall production costs.

Four-column hydraulic press can be used for metal forming, bending, straightening, deep drawing, punching, metal cold extrusion molding, metal hot forging, composite hot press molding, powder products (metal, non-metallic) molding, press-fitting, extrusion and so on. Hydraulic presses have a wide range of applications in the automotive, aviation, aerospace, metalworking and pipeline industries.

Four-column hydraulic press with button centralized control, can be adjusted, manual and semi-automatic three kinds of work: the machine's working pressure, pressing speed, no-load fast down and deceleration of the stroke and the range can be adjusted according to the needs of the process, and can complete the ejector process, can be brought to the ejector process, the tensile process of three kinds of process mode, each process and for the fixed-pressure, fixed-range of two kinds of process action for choice, the fixed-pressure molding process in the The fixed-pressure molding process has an ejector delay and automatic return after pressing.
