Wire Nails are produced by wire Nail Making Machines. The Nails are to be polished as well finished products. The quality of the Nails produced depends upon the wire used on the Machine. Generally, the wire received from the supplier is found dull due to Wire Drawing process and also some times gets rested due to weather effects. The wire for process of cutting Nails is not so bright as a result, the Nails produced do not have brightness and shining. Such finishes are never acceptable to the buyers. Thus, the Nails do require polishing which results in an attractive finished products.
To overcome this difficulty, the machine known as Polishing Barrel has been devised. The polishing barrels are available in two size viz. 250 kgs. and 500 kgs. Capacities per charge.
1) Load the polishing barrel with wire nails 3 to 4 inches above the half size of the barrel and remaining portion with Saw Dust. If the Nails are found rusty, it is advisable to Mix a little quantity of paraffin oil (Half liter Kerosene) prior to loading of Saw Dust. Rotate the barrel with blind lid on, for about 10 minutes. After this process, load the barrel with Saw Dust and rotate the barrel for about 30 minutes fixing blind lid-take out blind lid and fix up perforated lid to take out Saw Dust from the barrel by rotating. Continue this process again for about 40 minutes loading the barrel with fresh saw dust. This will result into bright shining look of Wire Nails. The Saw Dust used in second sequence can be re-used for the first cycle of the same process in next batch. This ensures economy of Saw Dust and solving the storage space.
2) If the mirror finish is required on the Nails, it is advisable to use SOFT LEATHER PIECES in second sequence of polishing instead of Saw Dust, 15 to 20 kgs. of such LEATHER PIECES are required for out 250 kgs. Capacity Polishing Barrel. These LEATHER PIECES can be applied again and again for about 15 to 20 cycles till they become very oily.
