The document introduces an automatic unloader called a sprue picker that can increase production efficiency for ball pen manufacturing. The sprue picker integrates into existing systems with safety functions and operates using pneumatic air for quick response while consuming low power. It provides flexibility to adapt to different products and brings benefits like reduced labor and electricity costs through more stable processing parameters and controlled rejection rates. The sprue picker investment of Rs. 1,200,000 for 4 units would pay back in 18 months based on estimated annual savings of Rs. 766,889 from reduced labor and electricity costs.
