Rod

Rod Casting process of button making technology currently used by us is from Bonetti, Italy. Rod Buttons is poured by a W-shaped pipe. Pour the completely mixed Unsaturated Polyester resin, Pigments and other chemicals into the waxed aluminium tube (different sizes) through a special oscillator (casting process). When the resin become soft glue, pull out the resin stick from the aluminium tube (different sizes) and then cut it into slices (thickness wise). After the curing process, the state of sliced blanks will turn into hard.
