2. Introduction • What is a Hydraulic Press? - A machine using a hydraulic cylinder to generate compressive force. - Operates based on fluid pressure to compress, shape, or mold materials. • Importance in Engineering: - Used in manufacturing and production where large force is needed. - Examples: Metal forming, automotive component assembly, plastic molding.

3. Principle of Operation • Pascal's Law: - Pressure applied to a confined fluid is transmitted undiminished. • Basic Operation: - Hydraulic press has two cylinders: input (applying pressure) and output (where work is done). - Small input force generates large output force.

4. Key Components of a Hydraulic Press • Hydraulic Cylinder: Converts fluid pressure into mechanical force. • Pump: Supplies pressurized fluid (typically oil). • Reservoir: Stores hydraulic fluid when not in use. • Valves: Control fluid flow and piston movement. • Piston: Moves within the cylinder to apply force.

5. Working Mechanism • Fluid Power Transfer: - Fluid power is transferred through pressurized oil. - Fluid is pumped into the cylinder, moving the piston. • Step-by-Step Process: 1. Fluid is pumped into the cylinder. 2. Pressure moves the piston. 3. Material is compressed or shaped under the piston.

6. Types of Hydraulic Presses • Manual Hydraulic Press: - Operated by hand using a lever or foot pump. - Suitable for small-scale operations. • Power-Driven Hydraulic Press: - Operated by electric or diesel engines. - Suitable for large industrial applications.

7. Design and Sizing of Hydraulic Press • Force Capacity: Based on pressure and area of the piston. - Formula: Force = Pressure × Area • Stroke Length: Distance the piston moves, affecting motion range. • Sizing Example: A press with 100 kN force at 20 MPa requires a cylinder with 5,000 mm² area.

8. Advantages and Disadvantages • Advantages: - High force with minimal effort. - Precise control, low maintenance. • Disadvantages: - Slower cycle time, higher initial cost.

9. Applications in Industries • Automotive: Used in forming car body parts. • Metal Forming: Ideal for deep drawing, punching, and forging. • Plastic Molding: Widely used in producing plastic products.

10. Conclusion • Recap: - Hydraulic presses use fluid pressure for high-force applications. - Key principle: Pascal’s Law. • Future Scope: Smarter controls for efficiency and automation. • Q&A: Open for questions.
