Golf club how its made

The head of these golf clubs are made from aerospace grade stainless stell to produce them the factory begin with a wax replica of the clubhead to make this wax pattern as it is called they inject not wax a mold they extract pattern  and snip off the bulk of the excess wax using hot wax as adhesive a robot joins several patterns to other wax parts in the shape of gates and runners the term for the cannels that guide molten metal into the casting mold then the robot dips these pattern into liqiud ceramic material four times with a shower of silica sand in between each coat the ceramic and sand harden forming a shellaround the wax patterns then the factory melts out the wax the shell is now a mold with which to cast the metal clubheads on the casting floor a furnance heat stell bars to 3000 degree fahrenheit well beyond the melting point the pouring techinique is critical the metal must flow at a consistent rate to prevent the formation of air bubbles after five hours a pneumatic hammer break part the mold workers saw off he gates and runners seperating the clubheads then very griad off the last remnamants of the gates and runners a turn table runs the club heads through a sand bluster which gives the metal a particular finish next ,they stick on a metal badge bearing the club's model nake they apply a dot of automatic point  the color indentifies the angle of the club there are 12 different angles now they rine the neck of the club head with epoxy then coat the end of the shaft with epoxy and slip into the neck a pnumatic hammer pushes the shaft in as far as it can go the shaft is made of either extruded steel or carbon fiber now it's time to work on the shaft first,they act it to the right length depending on the model then they put the shaft on a spindle and wrap the top ten inches in double sided tape to hold the club's rubber grip  they lubricate the tape and the inside of the grip before sliding the grip over the shaft a laser line helps them align the grip in the right position this is critical ,because the grip is the golfer's guide to correct hand position which is essential to a good swing next,a computer reads the lie the term for the club head angle relative to the ground then it reads the loft the term for the angle of the lubhead's face the computer then tells the technician what adjustments to make once he is made the adjustments to make once he's made the adjustments the computer reanalyzes the new loftvand lie to ensure they are perfectit is this type of precision that ensure these golf clubs fit the quality specification
