Method for manufacturing a spool

Abstract

A method for manufacturing a reel seat includes annealing an aluminum ingot at a temperature ranging from 450° C. to 500° C. for 5˜10 hours and the temperature is then reduced to 220° C.˜280° C. The aluminum ingot is then cold-forged. Next, property of the aluminum ingot is adjusted by heating the aluminum ingot to a temperature ranging from 450° C. to 600° C. for 3˜8 hours and the cooling the aluminum ingot in water. Then, the aluminum ingot is heated to a temperature ranging from 150° C. to 250° C. for 7˜11 hours. The aluminum ingot is then cut to a precise size and shape.

What is claimed is:  
     
         1 . A method for manufacturing a reel seat, comprising: 
 (a) annealing an aluminum ingot at a temperature ranging from 450° C. to 500° C. for 5˜10 hours and the temperature is then reduced to 220° C.˜280° C.;    (b) cold-forging the aluminum ingot after step (a);    (c) adjusting property of the aluminum ingot after step (b) by heating the aluminum ingot after step (b) to a temperature ranging from 450° C. to 600° C. for 3˜8 hours and the cooling the aluminum ingot in water;    (d) heating the aluminum ingot after step (c) to a temperature ranging from 150° C. to 250° C. for 7˜11 hours; and    (e) cutting the aluminum ingot to a precise size and shape.    
     
     
         2 . The method as claimed in  claim 1 , wherein the aluminum ingot is cut in step (e) by computer numerical control.  
     
     
         3 . The method as claimed in  claim 1 , further comprising a step of treating an outer surface of the aluminum ingot after step (e).  
     
     
         4 . The method as claimed in  claim 3 , wherein the treating includes chemical polishing, anode treatment, coloring, and closing in.
