How to Choose a Hydraulic Oil Press Model: 300, 325, 355, and 500 Series
Published: March 15, 2026Category: Technical Knowledge
Many buyers ask for the largest tonnage they can afford, but hydraulic oil press selection should start from raw material, process, and real daily output. A model that fits the project usually performs better than a machine that only looks bigger on paper.
Do not judge by model number alone
Check batch size, cycle time, hot or cold press, raw material hardness, and planned working hours. These factors decide whether a model is actually suitable.
Quick guidance by series
300 and 325 series are practical for hot pressing and small-batch cold pressing.
355, 400, and 426 series are more stable for long working hours and premium cold pressing.
480 and 500 series are better for larger projects, harder materials, and higher structural demand.
Questions to answer before buying
Which oilseed will be your main product? Is the project retail or bulk? How many batches per day are required? Will the line be expanded later?
Do not forget supporting equipment
Pretreatment, filtration, filling, spare parts, and operator training affect results just as much as the press model.
Conclusion
The best hydraulic oil press model is the one that matches your material, process, and sales plan together. Good selection reduces both cost and future adjustment work.
