Main Process Types for Frame-Type Hydraulic Presses

The main process types for frame-type hydraulic presses can be categorized based on their core functions. The following information is provided by the team at Jianlong Hydraulic Technology; please feel free to contact us with inquiries!

1. Metal Plastic Forming Processes

1.1 Deep Drawing: Pressing flat blanks into hollow parts such as cups or boxes (e.g., kitchen sinks, automotive body panels).

1.2 Blanking/Shearing: Separating sheet metal using dies; includes operations like punching, blanking, and trimming.

1.3 Bending and Flanging: Bending sheet metal to specific angles or curvatures, or turning up vertical edges along the periphery.

1.4 Cold Extrusion: Inducing plastic flow in metal within a die at room temperature to form parts with complex cross-sections.

1.5 Calibration and Straightening: Applying pressure to deformed workpieces (such as shafts or beams) to restore dimensional accuracy and shape.

2. Press-Fitting and Forging Processes

2.1 Press-Fitting: An interference-fit process involving the pressing of parts—such as shafts, bearings, or gears—into holes or onto shafts.

2.2 Forging: Includes open-die forging, closed-die forging, upsetting, and drawing out; used for shaping alloy steel and non-ferrous metal blanks.

2.3 Powder Metallurgy Compacting: Compressing metal powder into blanks of specific shapes and densities.

3. Composite Material Molding Processes

3.1 SMC/BMC/DMC Molding: Curing sheet or bulk molding compounds (SMC/BMC/DMC) under heat and pressure within a mold.

3.2 GMT/LFT Hot Pressing: Hot-press molding of glass-fiber-reinforced thermoplastic materials.

3.3 Other Composite Materials: Out-of-autoclave molding of prepregs (e.g., carbon fiber, aramid fiber).

4. Other Pressing Processes

4.1 Rubber and Grinding Wheel Pressing: Molding products that require high pressure, such as rubber components and grinding wheels.

4.2 Environmental Recycling Pressing: Compacting materials like metal chips, waste paper, and plastics into bales or briquettes. 4.3 Magnetic material pressing: Compression molding of magnetic powders such as ferrite and NdFeB (neodymium-iron-boron).

5. Classification by process temperature

5.1 Cold pressing: Performed at ambient temperature; examples include cold extrusion, blanking, and press-fitting.

5.2 Warm pressing: Pressing performed with heating to below the recrystallization temperature to improve formability.

5.3 Hot pressing: Forming performed under heated conditions; examples include composite material molding and hot forging.

In summary, the process capabilities of frame-type hydraulic presses cover virtually all categories of pressure processing—including separation, forming, press-fitting, forging, and molding. Their high-rigidity frames make them particularly suitable for applications requiring high tonnage, high precision, or the ability to withstand off-center loads.
