The extrusion process involves:

Billet Preparation:

• Billet heated to a specific temperature for increased ductility.

Extrusion:

• Billet placed in the billet container.
• Hydraulic pressure applied to the billet, forcing it through the die.
• Billet takes the shape of the die.

3. What factors influence the quality of a hydraulic billet?

Critical factors include:

• Material properties of the billet.
• Temperature and pressure during extrusion.
• Die design and condition.

• Implementing automation and controls.

9. How do you handle variation in billet material properties?

I would:

• Adjust extrusion parameters (pressure, temperature, speed) to accommodate material variations.
• Monitor billet quality closely and make necessary adjustments.
• Work closely with suppliers to ensure consistent billet quality.

10. Explain how you would use data analysis to optimize the billet making process.

I would use data analysis to:

• Identify trends and patterns in process parameters.
• Correlate billet quality with specific process conditions.
• Develop models to predict optimal extrusion settings for different billet materials.
• Monitor and control process variables to improve consistency and efficiency.
