The programmable motion profile of a 4-post servo press ensures gradual force buildup, precise final positioning, and documented force-displacement curves for quality validation and process control.

Industrial & Heavy Equipment Assembly

In industrial and heavy equipment manufacturing, a 4-Post Servo Hydraulic Press supports hydraulic component assembly, pump housing assembly, cylinder rod insertion, structural component joining, and sub-assembly calibration. Even load distribution across the press bed ensures consistent alignment and reduces stress concentrations during large assembly operations.

The open 4-post design also allows integration with automation systems and robotic loading, supporting high-throughput production lines.

Aerospace & Precision Assembly

In aerospace and precision manufacturing, assembly presses are used for structural bracket installation, precision fastener insertion, landing gear component assembly, and controlled-force joining of lightweight materials. These applications require extremely tight tolerances and validated process data to meet industry compliance standards.

Servo hydraulic systems provide programmable tonnage control and integrated quality data logging, enabling manufacturers to track every assembly cycle and verify force parameters for traceability.

Why Use a 4-Post Servo Assembly Press?

Manufacturers choose a 4-post servo hydraulic assembly press because it offers programmable tonnage limits, force-displacement monitoring, adjustable insertion speeds, consistent press depth control, integrated quality data logging, and even load distribution across large assemblies. This combination of precision and repeatability makes it ideal for automated production environments requiring both performance and documentation.

The MTP-SV Series 4-Post Servo Hydraulic Press (35–200 ton) is ideal for light to medium-duty metal forming operations requiring controlled tonnage, adjustable stroke, and even load distribution across the entire platen.

The servo-driven hydraulic system allows programmable motion profiles and controlled forming speed, making it ideal for applications where material integrity, dimensional accuracy, and surface quality must be maintained throughout the forming cycle.
