An oil expeller machine is a complete oil extraction system that includes a feeding hopper, pressing chamber, worm shaft, cage bars, gearbox, and motor. Together, these components crush oilseeds and separate oil from oil cake.

From a manufacturing point of view, the performance of an oil expeller machine depends on:

• Accuracy of machining
• Quality of raw materials
• Strength of the gearbox
• Proper chamber and worm design

This is why experienced manufacturers like Rajiv Engineering Works emphasize precision engineering and quality control during production
