Goodsjack designs and manufactures a variety of customizable hydraulic presses. 4-post hydraulic presses, also known as 4-column presses, can be designed to accommodate dies of any size and are well suited for part manufacturing that requires superior rigidity and precise bed-to-ram parallelism.

4-Post style presses are most commonly found in the 20 to 1,200 ton capacity, as requirements beyond that would generally call for a different style of press, such as a straight side or column press. 4-post presses are advantageous because they are typically more economical than gib-guided presses and allow four-sided access to the working area. A typical configuration may be designed with:
Multiple posts (4-post is most common)
With or without moving platens
Heated platens
Cushion or knock-out
Bolster plate
Our experienced engineering staff partners closely with clients to ensure their press is built to their exact specifications.Goodsjack equipment is built with rugged, heavy-duty construction, designed to meet demanding production schedules with years of trouble-free operation.

When to use a 4-Post Press
4-post presses are favored by manufacturers who have applications where larger dies are required, as the 4-post design can be expanded as needed. The 4-post design is also ideal when the platens need to be perfectly parallel through the stroke, as the design means it will not suffer from gapping and provides completely even pressure. Other press types such as gap or c-frame may be acceptable for applications where prefect parallelism is not necessary.

Differences Between 4-Post Press Tonnages
Goodsjack 4-post presses can be designed and built to accommodate smaller loads, such as a 30 ton model. These models, which occupy a smaller footprint are designed with heavy-duty plate construction. Machines on the larger side, such as a 1,000 or 1,200 ton model, occupy a larger machine footprint would be built with a robust weldment construction. No matter the size of press, Goodsjack equipment is always built with our signature rugged, heavy duty construction, designed to meet demanding production schedules with years of trouble-free operation.
