Rapsri can manufacture permanent mold castings ranging from a few grams to up to about 20 kilograms. While the smaller sizes are manufactured by manual process, the bigger sizes are manufactured on machine with automated PLC controlled tilting and mold coating facility.
The casting profile is machined into a specialty mould material (two or more depending on the complexity of the part), along with the gating system. The machined molds are then assembled along with required cores into a die assembly. The metal is poured into a die which then flows under gravity while being skillfully tilted to fill the mould appropriately. After the casting is removed from the cavity the moulds and cores are cooled in a proprietary solution which readies it for the next cycle.
